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.

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.

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.

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.

Using Tiles for Stairs

rough stairs tiles white color, at lighthouse restaurant Gaza 2011

Selecting proper tiles for stairs is a hard mission, because stair is in high traffic area. Designers choice a high strength cladding material like granite because it’s solid. Due to high price of granite, usually people choose the cheapest granite type. Rosa Beta, has a low price because it doesn’t look nice, traders says “Rosa Beta is granite in marble price”. Using marble is the next option, but marble surface will scratch and fragment due to stairs’ high traffic. However marble is weak and nice, but could maintenance easily by grinding and polishing it surface. after maintenance and renovation marble will look as it’s installed yesterday. Porcelain tiles is economical choice, it’s artificial material where tile body could be different from tile’s face according to different types. This post will cover how to select tiles for stairs, what are riser and tread connections types and how to install stairs’ tiles.

How to Select Porcelain Tiles for Stairs

Selecting the proper stair tiles is a sensitive mission. Take in mind few things while choosing stair’s tile: the tile’s classification, the size of the tile, the glossiness, and finally choice anti scratch tile.

  1. Do not use ceramic tiles, ceramic body is weak and stairs has high traffic. Also ceramic’s body color usually is red and this doesn’t fit the connection between step’s riser and tread. Even for porcelain’s tile Choice full body tile or color body’s tile. 
  2. Choose proper size tile’s to fit stair’s width. In market, there are tiles in size of 120*40 cm and 120*60 cm. These tiles size fit with stairs’ in width of 120 cm or less. Using small tile’s size isn’t recommended because tiles will be weak and easy to break.
  3. Choosing matte tile’s or high glossiness, depends on the context design. Personally i don’t like glazed porcelain, because glaze layer is usually wave. Matte tile’s is a better choice especially for riser and step tread connection as we will discuss in the next paragraphs. 
  4. One last thing to take in consider especially for high glossiness glazed tiles. Due to stair’s high traffic, tile could scratch, it’s recommended to choice anti scratch tiles. Also you can test scratch resistance at material lab.

Stairs Tile’ Edges Types

The difference between marble and porcelain, marble’s edge could polish to have safe edge in nice finish. This due to marble’s body and surface are the same material. When it comes to tiles, even full body tiles, tile’s polished edge glossiness won’t appear as nice as the surface glossiness. Therefore designers look for special edge details for riser and step treads that fit porcelain material. There are several types for edge details either by installing tile trim or polished porcelain tiles: bull nose type, straight riser, or to use advanced details like Costa Retta or Gradone types.

Tile trim

This by installing a porcelain, metal or stainless steel tile’s trim at the connection between riser and step tread. The tile trim will have a hard edge however it doesn’t have a high aesthetic value.

Tiles for stairs

Some manufacturers produce tiles for stairs, these tiles in width of 30cm and different lengths. What is unique of these tiles that it’s design with edge suitable for stairs and an anti-slip lines. Those lines are important to implement in stairs with tile, marble or granite finish.

Bullnose

This type of stair’s tile, by cut and polish the edge of step tread in round or semi-round end. The edge will be safe and hard to break. On the other hand, the tile has to be full body or color body, to allow edge polishing. Another disadvantage of this type that not all tiles contractors could implement it, because it requires special machines.

Straight or Angled Riser

Simplest way to install stair tiles. Where riser installed at right angle or acute angle to improve the safety of the staircase. In case of acute angle, craftsmen create a template to install riser, this makes the job easier and aligned. In right angle, tread lay over the riser, and 45 degrees edge use when tile’s body difference than the surface. It depends on the quality of tiles, remember that 45 degrees edge connection is weak.

Straight Nose (Costa Retta)

This by creating a detailed step nose from several tiles pieces. Implement this type require an experienced craftsman. The void of nose is filled with cement mortar. Costa Retta is Italian word mean straight nose, this type has a high aesthetic value.

Large Step (Gradone)

This method also has a step’s nose but it’s simpler to implement than Costa Retta. This by gluing a tread as shown in the following photo. Gradone mean long step in Italian, also this type has a nice appearance.

Installing Tiles on Stairs

Installing stair tiles need a professional, he needs to also calculate the height of stair’s risers. Then making few millimeters slope at step’s tread toward downward. Tread slope is necessary to prevent water from collecting on each stair tread, for long periods of time. Tiles laid over cement mortar, and below the mortar a mix of sand and cement in 1:1 ratio. The cement and sand mix, will be a concrete when water reaches it through tiles or tile’s grouts. The last important thing to implement is anti slip lines at each step, this is necessary for outdoor and glazed stairs.

Conclusion this, installing tiles at stairs is economical but has to choose the right tile and install it the correct way. The following photo is porcelain tiles’ stairs installed 13 years ago in high traffic outdoor restaurant. Thousands of people pass through this staircase daily, the stair situation still good compared to it low price.

How to finish porcelain tiles 45 degree corners?

You have two options, for outdoor use cement grout, it won’t give the best solution. For indoor and away from sun rays, use marble adhesive it will give better appearance and finish as shown in the following photo.
