Floor Tiles Skirting

Thin Porcelain tiles skirting, Gaza 2019

Floor tile skirting is a short wall tile to protect wall from water and to give the walls a nice finishing. The main function of floor tile skirt is to protect the wall from water during floor cleaning. Furniture against the walls will scratch and damage it, tile skirting keep a small distance between wall and furniture. Also tile skirting keep a nice appearance of the connection between tiles and walls. Floor tiles skirting can be made from different materials according to the space function.

Tile Skirting Height

Since tile skirting function is to protect the wall from water, several centimeters height are enough. The tiles skirting nice height is 7 cm, I have tried shorter and higher skirt but wasn’t nice as 7 cm in height. Keep in mind that for some special cases, like when the wall has marble cladding one or two centimeters are enough. Select skirting material with low water absorbing to protect marble from water. Select a black granite skirting it will look as a nice shadow line detail.

For tile cladding wall there is no need to install tile skirting. Another special case when there is a wall in less than 15 cm height, like what is used for handrail balcony or curtain wall detail. I prefer to avoid few cm painting wall over the skirting, therefore skirting could be higher or from the same material as sill to appear as a block of marble.

Skirting Cutting Problem

Many companies produce tile skirting in a certain size, these skirts have a straight edges.  Other times, craftsmen cut tiles in certain heights to make the tile’s skirting. There are several methods to cut a porcelain or ceramic tiles either by manual tile cutter, grinder or a saw machine. Cutting tiles using manual tile cutter or grinder won’t have a straight edges. Craftsman will install bad cut edge at the bottom, to avoid it appear to the human eye. Then cement grout used to fill the bad cut edge connection. This cut method can be used if there is much tile pieces that have at least one straight edge. The best tile cut method is saw machine to have straight edges. Not all tiles contractors have in-site saw machine, therefore sometimes they send it to marble workshop to cut them.

Skirting Round Edges

At the British International School in Gaza project, it required a recognition from the UK. One of the main requirements to get the recognition was student safety, therefore they asked to round skirting edges. The marble flooring and skirting disassembled, then send them to marble factory to round the top edge. Full-body porcelain can round it edge, while full-color porcelain the round edge will have similar color to the edge and won’t look nice. However, can’t round ceramic or veneer tiles because the bisque layer is weak and have a different color.

Skirting Corners

It’s important to notice that skirting require a 45 degree cut as shown in the following photo. It can’t install over each other to avoid tiles bisque layer to appear. Half on half and other detailed connection doesn’t suite the skirting scale. Also 45 degree corner connection suite when the skirt has a top round edge.

Plaster Paint  and Tile Skirting Details

As tile skirting role to have a nice wall floor appearance, the wall-skirt detail is important. Most walls have plaster and painting finish and sometimes a wallpaper finish is used. 

For plaster craftsmen like to end their work 15 cm from the top of concrete. 10 cm is the finish floor level, then tile skirt require 7 cm. This means tiles craftsman have two choices either to lay skirting tiles over plaster works or to remove the plaster then lay the skirt. I prefer to remove the plaster then to lay tile skirt to have less thickness skirt. Another finish alternative, when plaster craftsman leave 20 cm from the top of concrete instead of 15 cm. This way they need to finish the 3 cm plaster after the tiles work finish and before tile joint grout begins. 

For painting works, the most important to make a sharp edge between painting and tile skirt, and it’s better to make a round edge to have a nice finish. Also for wallpaper it’s important to know where to end the wallpaper.

Tiles Expansion Joint

For high temperature countries like Arab Gulf, tiles expansion joint is important. In outdoor and large spaces expansion joint can be installed each 4 meters in both directions. Another expansion joint at room boundaries and in the connection between wall and floor. A centimeter that doesn’t have either tiles or a mortar, then it’s filled with rubber material like SikaFlex or other products. Then the tiles skirt will cover the expansion joint and won’t appear for the human eyes.

Tiles Skirting Connection with Doors

The connection between door and tiles skirting is a sensitive detail. Where door frame install after tiles works and sometimes after the painting works to keep it clean. So site engineering has to give the tiles craftsman where the tile skirting ends. So when the door frame installed they have a nice finish together. Sometimes interior designers make a door frame base to avoid bad connection with tile skirt.

How to make curved walls skirting ?

Well, tiles and natural stone materials can’t bend according to the wall curve. Therefore the best solution is to divide the skirt into smaller width size according to the wall curvature. Dividing the skirt width will give a not bad solution that will have a bad appearance.Curved wall skirt using small width species, Gaza 2016

How to Select Ceramic and Porcelain Tiles

How to select a trendy porcelain tiles
How to select a trendy porcelain tiles, Alsiksik showroom Gaza 2019

Ceramic and porcelain tiles are artificial building materials made of clay, with a nice colored layer then a glaze layer in the top. The alternatives in clay types – the bisque layer – is different from ceramic to porcelain. If it’s red then it’s definitely a ceramic tile, ceramic is weaker and has more pores than porcelain.

Porcelain is treated by firing process to increase it strength in order to resist scratching and water absorb. Porcelain types are veneer surface, full-color and full-body porcelain. Veneer is just a thin top printed layer with off-white color bisque. Full-body porcelain has colored bisque layer, usually it has different colors to form particles or to have veins like style. Full-body tiles is allowed to surface grind for maintenance, also if the surface scratch the body has the same texture. Full-color porcelain is a cheaper alternative, it has two layers, the top surface is printed and bisque has color similar to surface texture.  

Last several years, when tiles’ production bloomed. The tiles have more textured finish alternatives ranging from shiny, soft reflection, rough and in addition to 3D geometric tiles. As a trend, designers use the tiles that similar to wood, natural stones and concrete like tiles. Porcelain production’s developed to have products that are similar to natural materials in texture, reflection and seamless tiles prints.

Ceramic and Porcelain Tiles Texture

Rough and 3D geometric tiles become more popular recently. in order to have an appearance closer to natural materials. Some tile’s designs have several 3D forms to create a more natural and realistic appearance. Rough and 3D surface tiles are not suitable for floors, where it’s hard to clean. Rough and 3D geometric tiles designed for a wall decoration. Use 3D geometric and rough tile to create a focal point by applying a graze light to it. This idea suite small spaces like toilet and bathroom. For rough surface tiles use a defined boundary wall that doesn’t have openings or fixtures to avoid bad connections.

Ceramic and Porcelain Tiles Printing

There are two methods of tiles printing, the printing veneer and full-body casting types. In both methods, it’s always better to have different printings. The different prints will have a more natural appearance, four and more seamless prints will increase the tiles price. Full-body casting will definitely have seamless tiles, since it’s casting the mix could have slightly different tones. The different tones will look ugly next to each other, each tile package has a tone number, keep an eye on that. To reach economical casting solutions, producers created combination type of porcelain. The combination by casting the top surface at porcelain bisque. The combination type porcelain is the tiles manufacturing trend, the tiles casting is in competition to veneer printing tiles price.

Ceramic and Porcelain Tiles Reflection

Ceramic and porcelain tiles has glaze layer, this  glaze layer could be matt, slightly reflect or high glossy.  The traditional shiny tiles that have a high gloss became timeless. The matt and rough tiles’ finish took it place to look similar to natural materials. 

Porcelain manufacturing contain the firing process, this by applying a high temperature to porcelain. Firing process give the glaze layer strength to resist scratching and fill the surface pores to be a waterproof layer. The porcelain fire process disadvantage is that glaze layer will wave. The waving will appear more in high glossy tiles, and decreasing in less shiny surface and won’t appear for matt surfaces.

Matt tiles suite lighting design more than glossy tiles. When light source reflect at glossy tiles will it mirror the light source gives visual noise. Designers use matt and rough tiles that doesn’t reflect light, to have a visual comfort.  The only problem face matt and rough tiles is cleaning, where the rougher the surface is, the harder to clean it surface. Therefore we prefer not to use at floors. But also keep in mind that a high gloss tiles is hard to clean, it has always to appear elegant and shiny.

FAQ

Ceramic tiles bisque is red?

Most common it’s red but no, it’s can be a white clay as well. Many tiles showrooms present white clay ceramic tiles as it’s porcelain to increase the ceramic tiles price. Ceramic has more pores than porcelain, if it’s rough it’s white ceramic clay. Also you can test it by applying water to tile back, where ceramic absorb water more than porcelain.

Beauty of Travertine Veins

Travantine is a natural stone classify as limestones. Travertine stone is unique by it veins, pores and holes, this what gives it more aesthetic value. These make travertine soft, absorbent and it doesn’t resist the weathering action well. Travertine become known by its veining, it’s the beauty of travertine. Also Travertine is known by its warm natural range of colors, in tones of beige, cream, brown, yellow, orange, red, gold, silver and a wooden like texture. Travertine formed in salted lakes from calcium carbonate. In most often travertine found in Italy, Turkey, USA, Mexico, Peru and Croatia. This post will discuss several topics you need to know before selecting travertine.

Travertine Applications

For thousands of years travertine is used as a common building material for walls and decorations. Since travertine has pores and holes, which is hard to fit some applications like floor, stairs and sinks. Travertine holes need to be filled, and pores to seal in order to achieve these applications function. Travertine holes could filled with cement grout or marble adhesive.

Cement grout is holes filler, where cement will absorb water and it became darker. Also cement won’t have the same reflection as travertine surface. On the other hand, marble adhesive is available in many colors as well as transparent base. Marble adhesive doesn’t effect from water and will remain with the same color. The disadvantage of marble adhesive that it will break and fragment when exposed to sun rays. Therefore, as holes filler and joints between tiles, it’s better to use cement grout for outdoor and marble adhesive for indoor applications.

Pores also affect how travertine will look over time, sealer can protect travertine and keep the surface beauty over time. There are several products in the market to protect travertine surface and keep the same glossiness or the rough surface. Be aware that rough surface is harder to seal, because it has more pores and it requires a matte sealer.

These solutions allow designers to select travertine as marble and granite, especially because travertine has unique colors and texture. The below photos shows the use of travertine as sink, stairs and other applications.

Travantine Veins

As mentioned above, travertine is unique by it softness, veins and holes. Travertine is groups of light and dark veins. The most important thing is to arrange travertine tiles before installation in order to have the continuous veins. Arranging will show the travertine tiles as art, a mass, or as slab of travertine. To have a continuous veins there are two methods, the continuous and book match arrangement. 

Continuous veins arrangement, when tiles are cut parallel to veins directions. Arranging tiles in stacked bond, or running bond that I recommend. Running bond is better because it will interlock the different tones together. Continuous veins arrangement is the best technique for travertine tiles.

Diagonal veins cut is suitable to be arranged continuously or in book match arrangement. Marble and travertine tiles and slabs that has a clear diagonal veins are suitable for book match arrangement. Book match arrangement adds aesthetic value to walls, the wall will look as continuous paint of travertine. To have a continuous veins for book match arrangement, where the back of travertine need to be polished.

The scale of travertine veins has an important impact, where most people consider smaller veins is more beautiful. This is true for interior scale, or in applications that is close to human eye. On the other hand the larger veins is more suitable for applications that has longer distance from human eye like architecture scale. Then in both cases you can enjoy the appearance of travertine veins to appear as a mass, or a natural rock.

Travertine Cross Veins

Cross veins travertine is also available. Cross veins cut required a rigid and solid travertine stone. it’s popular for American Travertine, the orange travertine like the one in the below photo. It’s like particles of different colors and tones instead of continuous veins.

Travertine Decoration

Travertine Tiles and mosaics are available in different sizes and arrangement as decorations. Whites, greys, yelows, oranges and red shades makes the small tiles sizes and mosaic look nice. From french set, to straight arrangement, and other shapes that have classic appearance.

Travantine Finish Surface

Travertine came in different surface finish, range from polished, matt, brushed to rough surface. Personally i don’t like travertine with high reflection, rough travertine surface reflect the less amount of light and sound. This makes it suitable for building cladding, where weathering will add more aesthetic value to it. Also it’s suitable for interior spaces, especially public spaces that require less echo wall cladding finish materials.

FAQs

How to install travertine walls?

Travertine can install at walls either by casting, using cement mortar or glueing using tile adhesive. I prefer to install using transparent tile adhesive for two reasons. The first reason is that travertine has pores and holes which means cement could be pure during casting, which will look ugly. Another reason I prefer gluing, is also because pores and holes that tile adhesive could stick easy in them to enhance the connection between wall and travertine. To gluing the travertine it requires to plaster the wall in a good leveling, and remember that tile adhesive can’t have a thicknesses like cement mortar and casting methods.

What are the available travertine sizes in the market?

Travertine is available in similar sizes as marble range from, Slabs, Tiles and Stairs. Slabs are available in size of 1.7*2.8m in thickness of 3cm. Tiles are available in size of 30*60 and 120*60 in thickness of 1.8cm. Stairs are available in several sizes, where the thickness of going in 3cm and 1.8cm for risers. The length of the stair step typically is 120 and 130cm and could be longer. Also there are other sizes like 15*15*1.8cm in diagonal veins direction and also french set, mosaic and other decoration sizes. Travertine red shades french set.Travertine slab

Marble Stairs Detail; The Shadow Line

Select the suitable stairs finish is a hard mission, especially for homeowners. There are a variety of finishing materials, details and style. Marble is the common use material that is strong and has a nice appearance despite it classic style. Personally as much as I love marble but i struggle to find a modern details. The shadow line detail is a method to get a modern appearance, that is suitable for the most type of marble. The shadow line has flush clean look with no overhang nosing to have a modern appearance. With a thin black granite underneath the riser, it shows each step by itself individually.

when to use the shadow line detail

As mentioned before the shadow line detail is suitable with many kinds of marble. It’s the best choice with marble that have different tones like Flower Beige marble as shown in the below photo. The shadow line detail will separate each step by its own, then people will not easily notice the difference in marble tones. Also it’s suitable with marble that has many veins, it displays the beauty of each step. On the other hand, it’s not nice with clear marble that look similar tone and doesn’t have veins. It’s not a bad choice but it won’t add much to the marble and stairs.

Installing shadow line marble stairs

The shadow line detail is simple and cheap detail comparing to another marble details. Because its regular straight steps with a 2cm black granite underneath the riser. Granite is prefer to used and not marble, because it’s thin we need a plain black color. Also granite is more rigid material to avoid the break the 2cm piece through cutting process. Personally I prefer black shadow line to be thinner than 2cm but then it will become weaker. There are three types of black granite, beside artificial stone read How to Select Black Granite article for more information. Artificial stone is not suitable because it will efflorescence and appear with with grey and white spots. The craftsmen need to cut the granite using saw cutting machine at marble factory, and then to glue it with the riser according to floor and riser height.

In conclusion, It’s not the only modern marble stairs detail, but it’s suitable for marble that has variety of tones or density veins. The shadow line detail is cheap compared to another modern marble stairs details. Also it’s well-designed, the design is avoiding water collecting and has no fine details that could break in the future.

FAQs

Can i do shadow line detail for porcelain tiles cladding stairs?

Yes, where a piece of black porcelain can stick using tile adhesive to the step rise. Then it’s filled with cement mortar as shown in the following drawing.

Porcelain Stairs Design

Development of outdoor stairs tiles, Before and after
Before and after installing stairs tiles for ORIGIN DESIGN office entrance. Gaza 2019

This project is stairs porcelain tiles as application for Using Tiles for stairs, the project is outdoor stairs for ORIGIN DESIGN office entrance. The old situation as shown in the before and after photo is black tiles and four steps of Rosa Beta granite. We have redesigned the stairs and garden to have four steps each in size of 120*150 cm. Beside the steps, will add grass in sloped level to enhancing stairs beauty, this beside rearrange and developing the landscape. Through this topic we will discuss stairs building stages from drawings, selecting tiles, building blocks, tiling and finishing.

Prepare Drawings and Selecting tiles

Stairs drawings designed according to available tiles at the market, usually designers have knowledge about tiles sizes at the market. The process after choosing the tiles size, is to select the proper tiles texture and color. In this project, I have selected parquet in size of 15*120 cm to fill area of 90*120 cm. Unfortunately, choices were limited in this size, and I haven’t like tiles texture and color for this size. As an alternative I have found 120*20 cm parquet tiles in color I like, but this size doesn’t fit the drawings. 4 tiles pieces will cover area of 120*80 cm, in addition to cut a piece to 120*10 cm, but it won’t look professional.

Drawings for stairs tiles using 15*90cm parquet and white matt tiles in surrounding

Another alternative in the market was a Spanish parquet tiles from UNDEFASA in size of 15*90 cm. This mean we can rearrange tiles where 8 tiles will cover area of 90*120 cm perfectly. For border tiles and risers, we selected light gray 120*60 cm Italian tiles from ABK in thickness of 7 mm. Both tiles color and texture match, and they add to stairs design beauty. 120×60 tiles need to be cut in size of 15*120 cm and few in size of 30*120 cm. In order to have a clear edge cut, we sent the tiles to marble factor to cut tiles using saw machine. Now tiles are ready for the next stage.

Building the Stairs

After ordering building materials from cement blocks, cement, lime and sand. And demolishing the old steps, in order to prepare the site for building as shown in the drawings. The block walls top-level built to be lower than tiles level by 5 to 10 cm. This due to block dimensions and to allow craftsman adapting the steps levels. Then to fill sand between steps walls, and top 10 cm was mix between sand and cement. The mixture between sand and cement will enhance the ground strength, If there is a water leakage it will become a concrete surface. After finishing these works, now we are ready for tiling stage.

Stair’s Tiles

Usually craftsmen begin to install stairs from first step at the bottom then going upward. in this case, it’s more convenient to use downward method by installing step tread then the riser. Another advantage of building upper level going downward because there is a certain upper level and flexible lower level.

First of all craftsman arrange tiles at straight level, matching parquet colors together making area of 120*90 cm. Then add gray tiles around them, we face a problem where the gray tiles are 119.5 cm instead of 120 cm. Also parquet make area of 121×90 cm, we planned to install parquet without grout, but still there is a millimeter between each. The solution was to cut a 1.5 cm from a parquet tile to have area of 120*90 cm. Together with the light gray tiles it made an area of 150*120 cm.

After installing the step tread, for the riser we use regular connection, where tread will lay over the riser gives straight angle. Also risers between each other will gather using 45 degrees method, to appear as one mass. 

Tiles Finishing

Finishing showing the beauty, especially for tile edges details. Grout is important, we used Vitra Cement grout CG1 white color for the stairs. Using liquid colors to give it a color similar to tiles, The parquet color is mixed using black, brown and mustard color. For the gray color we mixed to the black and a little brown color to the white cement grout. Notice that to have a well bond cement grout to the tile, you need to clean cement and sand between tiles. Then to fill the grout probably and leave to setting well. Then using metal sponge, clean the rest of the grout, you need to clean tiles well because they are rough.

Why tile size is 119.5 cm instead of 120 cm ?

This is related to shipping and size of shipping container. Tiles pack by cardboard to reach 120 cm, then it could fit the wooden plate. These few millimeters will save a lot of money. And sometimes this happens during cutting tiles at factory, Saw cutting will have the blade thickness around 3 mm. Therefore i prefer laser cutting tiles where it’s more accurate and thinner during cutting. 

Why not using a tile adhesive for the grout?

Tile adhesive will crack when sun rays reach it, so it doesn’t fit outdoor applications. Another reason not to use tile adhesive, that tile adhesive has fast setting, and it couldn’t clean the rest of the grout by metal sponge. It need to grind the material, this fit marble but tiles can’t be grinding.

Aluminum Composite Panels Edges

Aluminum Composite Panels (ACP) is modern, cold, lightweight material, it gives aerodynamic feeling for architecture. Aluminum Composite Panels Edges’ details and finishing is the beauty. Throughout this post we will discuss the different edge types, there are three main edges types: ACP edge’s profiles, Folding ACP and Gluing ACP edges. Edge types beauty is to have glossiness continuity of ACP panels to achieve aerodynamic feeling design. ACP designed to be able to groove and fold, this by using different machines and techniques. Also there are a method to install edge’s profiles.

ACP Edge’s Profile

Aluminum composite panels edges’ profiles available in different shapes to fit different applications. F profile use for right angle edge, while H profile use for straight angle edge, this beside other profiles for special uses. These profiles are available in different colors according to RAL index, also some materials like mirror and golden mirror …etc. Notice that ACP edge’s profiles have to fit ACP colors, if color isn’t available paint it using powder coating. Advantages of edge’s profile, it’s easy to install, edges will be straight, cutting finishing will be fair enough. However ACP edges’ profile are easy to install, but profile doesn’t have aesthetic value, where profile level is higher than sheets. Different levels mean glossiness won’t be continuous through different sheets, This hide the beauty of aerodynamic glossiness.

ACP Folding Edges

Despite its difficult and has high cost method but it shows the beauty of ACP. The folding concept by creating a groove at the back of ACP that allow the sheet to fold. The groove placement has to be well measured. The grooves implemented by a blade installed at router, or table saw, CNC machine cut and create grooves at one stage. The Blades are available in different sizes and shapes to reach the needed groove for required application. The difficulties facing folded edges’, it’s hard to level panels together, it’s a sensitive in-site mission need accurate. The high aesthetic value by having straight same level, and continuity of soft glossiness.

ACP Edges Gluing

For special cases like curves we could use edges’ profiles or to glue edges. Glue edges will appear better, however it’s sensitive and has many processes to implement. Although Gluing is weak compared to edge folding and profiles, and it won’t last for a long time. 
To implement edge gluing, it requires to cut both sheet ends at 45 degrees. Then gather them using Sikaflex, and avoid using indoor silicon. Notice that SikaFlex will glue in a while mean both sheets need to stay temporarily in place until SikaFlex dry. Check if SikaFlex dried by doubt it by a needle , if needle is clean this mean its dry, otherwise needle will have remains of SikaFlex. After that using small brush paint the edges with the same color of ACP. This Method is useful also for 3D applications and decorations ends.

Generally, Details have a big effect. The photo below shows a petrol station in circular shape and curve section I have designed and implemented for Alhelou Petrol station in Gaza 2018. The job was very sensitive and accurate, and edges’ finishing added much to this project. The client was happy and proud with the design and results. Now you have a good knowledge about ACP edges’ connections, feel free to ask any question. i like to hear from you.

Marble Floors Disadvantages

Installing Marble at Floor, ORIGIN DESIGN, Gaza 2019

Marble flooring give the interior an elegant appearance, however marble floor have many problems because marble is sensitive. Installing marble at floor is more sensitive than wall. At wall dust and water will slide away from marble, but on floor it remain at marble ruining it surface.

Level surfaces problem

One of marble floors disadvantages is surface level. After extracting marble from quarries , marble cuts into slabs using band saw or bridge type saw. Band saw produce a wave surface, comparing to bridge type saw it’s produce a straight surface. During installing of marble flooring, craftsman has to level the floor surface. IF the marble cut using band saw machines craftsman has to arrange the tiles in a way to avoid different surface level.

To check if marble surface leveled, keep you eyes at floor reflection, the reflected photo has to be straight not sporadic or wave. In case that marble surface isn’t leveled, it requires grinding marble and polishing it. Personally I don’t recommend grinding marble because original grinder will lose for longer period. 

Fragmentation of marble Surface

Another marble floors disadvantages is surface fragmentation. Marble floor has to be always clean, where dust and sand at floor with people movement will scratch marble surface, marble will lose reflection of marble. When small area in marble scratched it will affect other areas and will make the surface look bad. Although i prefer grinding marble only if the marble surface scratched, it will return as it installed last month.

Water as we discussed before, its ruin marble. Grinding marble surface can protect from natural factors like dust and water, but marble sides and back will gain water. It will gain water if there is a problem with sewage or water supply system underneath the marble. Therefore marble sides and back has to be protected against water and moisture. 

Palestinian Stone

Palestinian stone is located at West Bank Mountains. Also it’s called Jerusalem stone and marble, with average annual sales of 600$ million. Commonly it caved in a rough texture to use in building facade cladding and for decor. The Palestinian stones and it unique rough texture is a main character of the Palestinian architecture.

As Palestinian stones are limestone extracting from different mountains. Thus stone types are various according to location. Each stone has it physical specifications, where they vary in absorption ratio, rigidity and strength of bearing, leading to price differences. Most famous stone types are Njassa, Shyoukh, Slayeb, Tafouh, Barezit and many others.

Palestinian stone types

Njassa and Shyoukh are white. However Njassa is more white and has less absorption ratio which will remain white for longer type. In other hand Shyoukh Band 160 found deep inside the mountain, which is similar to Njassa stone specifications. Slayeb is red and yellow stone, its solid with a low absorption ratio. Taffouh is that yellow stone, while Birzeit is varied from yellow to grayish green but it yellow is more hue than Tafouh. There are other types found in Palestine like Beersheba stone in Negev desert. Its light gray color stone in similar tones, this gives architecture seem like it built from one stone building.

Palestinian Stone Extracting

Stone extracted then cut in slabs then to different sizes and thickness to fit the required application. What’s makes Palestinian stone unique in facade cladding, its has a rough face where it shows architecture massive. The well-known two major sizes, the 25 cm height and 12 cm height its come in 3 cm thickness and random widths. Personally I consider 12 cm height is more beauty in scale and details, however 25 cm scale and details appear differently because it requires a different caving techniques. Increase stone thickness could be a solution to have the large size appears in nice details similar to 12 cm stone size.  

Palestinian Stone and Water Absorbing Problems

Palestinian stone as limestone has a high water absorbing ration. Specially that rough Palestinian stone surface is not treated for water absorption. The stone will yellow and convert to black color that have a bad appearance and could easily noticed. There are a few tips to take in consideration to avoid yellowing.

First and most important to fix water leakage problems. Most usual problems happen in slab connection, where problems with indoor plumbing that affect the elevation stone cladding.

Also inverted beams around the building boundaries will prevent water to reach the Palestinian stone. The inverted beam has to be casting with slab to avoid water leakage. Another thing is to avoid installing water supply pipes at floor, and install the pipes in the false ceiling. In the false ceiling the problem will appear immediately, unlike floor installations. The cost of removing the false ceiling to fix the pipes is smaller than removing floor tiles for pipes maintenance.

Second tip is to temporarily connect stone together, use marble adhesive. Some craftsmen use gypsum to temporary connecting, but gypsum is organic material that wouldn’t stay for a long time. Then the place of gypsum mortar will be a gaps to collect water. The marble adhesive is better choice for traditional installing method – the casting -.
Stone types, cut sizes and arrangement have various alternatives, resulting huge methods to build and design of the building facade. Here are some photos of buildings elevation designs that created by Palestinian stone.

Palestinian stone joints

Rough Palestinian stone, use a wide joints that fills with cement grout. The nice width for the rough Palestinian stone is 7 mm. Where craftsmen use grinder to wider the joints. The grinder will straight the joint and give them the same thickness. As the joints between the stone tiles are wide it requires adding sand to cement grout. Sand will make the mixture rigid, rougher also sand will color the mixture. For white stones like Njassa, Shyoukh use white sand like sea shore sand to prevent yellowing the mixture. After filling the cement grout craftsmen use steel brush to clean the joints and after use grinder steel brush to clean the stone surface. For colored Palestinian tones like Beirziet, Slayeb or Tafouh craftsmen add pigments to color the grout.
