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.

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

How to Select and Buy Marble

Marble Samples

Marble is a metamorphic stone, it’s formed when limestone is exposed to high temperatures and pressures. Marble has more aesthetic than granite, veins add more to marble aesthetic value.
Select marble tiles and slab isn’t an easy mission, especially with the variety of choices in the market. Marble is a natural material extracted from mountains, each area in the mountain is different. It’s hard to compare marble types, because its similar in appearance but different in strength, water absorption and other properties we will discuss later in this article. For non expert who will get information from market, the flow of advice, maybe even conflicting advice, will make marble select process harder. Through this article we will go through marble properties and advice in FAQ style, try to read this article in full to get a well understanding of the process.

Everything you need to know about Tiles Grout

Grout is tiles joint – small space – between tiles, this space function is to allow the craftsmen to align tiles together. Typically spaces between tiles range from 2 to 4 mm and it measured by plastic grout spacers.

The size of tiles joints can affect the tiles style either modern or classic. For modern appearance usually we recommend arrangement tiles directly with no space. This fit laser cut tiles case, where tiles are well trimmed at 90 degrees angles. On the other hand, saw cutting tiles will have classic appearance. Saw cutting tiles are cheaper than laser cutting tiles, but during manufacturing it could have a difference in tiles size. This could appear clearly by eyes therefore it’s better to use large tiles joint about 7 mm wide. However in classic appearance tiles it more beautiful to leave a large grout space, but be aware to buy a good brand ground to avoid color changing.

Grout function is to align tiles together and it’s not expansion joints, because it could fill by cement grout or in marble tiles cases could fill with epoxy or marble adhesive. Both fillers type could be colored to appear in harmony or in contrast with tiles.

As expansion joint we recommended to leave around a cm between tiles and walls. The expansion joint will cover by tiles’ skirting. Expansion joints need to be clear from sand and mortar, then to fill with highly stretchable material like Sikaflex. Then it covers with tiles skirting.There is a special accessory for tiles expansion joints where it installed outdoors in high temperature countries.

According to ISO standards 13007, where grout classified according to materials to resin grout RG and cement grout CG. The cement grout classify to CG1 and CG2, of course CG2 is better. You can search about Iso standards 13007 for more information. Notice that there are few other factors affect grout quality. For example, the tile joint has to be clear from sand or dust, so the grout find a place it self. 

Cleaning Tiles Grout

Many people suffer from tile grout cleaning, especially floor cement grout. For cement grout, where cement has pores that could collect dust and dirt. Then the cement grout will become darker and look old. There are some chemical products that clean cement grout like Grout Cleaner from Fila. It will clean the cement pour from dust and dirty then partly close those pour. Designer sometimes use dark color cement grout, in order to protect it from color difference. Compared to epoxy or using marble adhesive as tiles grout, where it has less pour that won’t collect dust and dirt. The epoxy and tile adhesive grout is using only in indoor where sun will fragment it, making creaking and disassembled with walking friction.

Can i use Portland cement as cement grout?

Yes, cement grout is made of cement, either white or Portland cement – gray -. Then add pigment to give it a color and zinc to enhance it strengths. So if you want cement color grout add zinc to Portland grout and use it as tile grout. Use black pigment to make darker grey if you like.
