Indeed, white and gray tile adhesives are available on sale, made on the basis of white and gray cement.
The gray color of cement is mainly due to the presence of iron compounds in the original raw materials, so to obtain white cement, it is necessary to use raw materials with a low content of iron compounds and also apply bleaching technologies.
Of course, this affects the final cost of the adhesives; the price difference can reach up to 25%. Based on the technical data sheets of the manufacturers, we have: “THE ADHESIVE MIXTURE BASED ON WHITE CEMENT IS ESPECIALLY RECOMMENDED WHEN INSTALLING COLORED AND TRANSPARENT GLASS MOSAICS, AS WELL AS TILES MADE FROM NATURAL WHITE STONE AND SENSITIVE TO STAINING NATURAL STONE, BECAUSE NOT THIS IS THE ORIGINAL COLOR OF THE MATERIAL.” In other cases, you can use adhesives based on both white and gray cement, having previously read the technical data sheet.
I saw an adhesive based on white cement Kerakoll H40 Eco Marmorex in the display case of shopping mall KVADRAT. What explains its “high” price: several times more than other manufacturers and 2 times more than other “white” adhesives in the Kerakoll line?
Kerakoll H40 Eco Marmorex - provides very fast and high hydration, which binds the mixing water and prevents the formation of surface stains, ensuring the safe installation of sensitive marble and natural stone.
The price is determined by the following characteristics: 1. ULTRA-FAST BINDING AND CURING - thanks to a special mixture of fast-binding hydraulic substances, with a high content of white cement and polymers that increase the cohesion of the structure molecules;
2. HIGH LEVEL OF HYDRATION - thanks to a mixture of quickly binding substances with a high degree of hydration, which retain water in the mixture and eliminate the appearance of stains on the marble;
3. SHOCK ABSORBING SYSTEM (SAS) TECHNOLOGY - a testing technique to ensure traction in real construction conditions;
4. MARBLE CHIPS - used as a filler;
5. HIGH ADHESION - 2 MPa concrete/gress after 28 days.
White adhesives are also recommended for use when working with monoporosa ceramic tiles - single-firing wall tiles . Let me explain what this tile is.
The production of monoporosa is carried out using a technology similar to that of monocottura production, using a press and subsequent firing of tiles on which the glaze has already been applied. But the use of other components of the batch causes a change in both the physical characteristics and the scope of application of this tile, which are more close to bicottura.
High-density single-fired ceramic tiles, such as monocottura and porcelain tiles, are made using clay that has a high iron oxide content and the addition of a feldspar-based flux to provide strength. To make monoporosa, clay is required that is highly saturated with carbonates, the importers of which are France and Germany. As a result of firing, a white mass is created that has high porosity and moisture absorption. Its strength is significantly lower than monocottura; therefore, the tile itself has a thickness of about 12 mm and is used for interior decoration .
This technology makes it possible to produce large slabs. And, if in the production of bicottura a significant thickness of the enamel layer is required in light colors in order to hide the red base, then in monoporosis the white base eliminates such measures. This allows them to be executed in imitation of natural marble.
You can describe in more detail what we are talking about in the following phrase: AN ADHESIVE MIXTURE BASED ON WHITE CEMENT IS ESPECIALLY RECOMMENDED WHEN INSTALLING Stain-sensitive NATURAL STONE , which is written in the technical data sheet by manufacturers of tile adhesives.
Texture, permeability, mineral content, history of stone formation - all these properties are of great importance both for the process of laying the stone and for its further operational purpose. If natural stone is exposed to water, it will easily penetrate through the pores of the stone. Porosity ensures the spread of water, which, of course, affects natural stone and leads to a number of problems: deformation , staining , and the formation of efflorescence . Since the question concerned staining, I will describe this problem in more detail.
The coloring agent penetrates into the natural stone along with water. As soon as the water evaporates, the coloring substance is concentrated and, as a result, leads to the coloring of natural stone. These substances are found in the stone itself , come from the installation adhesive , or are contained in the base . The use of adhesive mixtures based on white cement can significantly reduce or completely eliminate the influence of the last two points.
I need to clad the facade of a two-story building with heavy slabs of light marble. Since the project is “serious” and the budget for construction chemicals allows the use of professional materials, I would like to use the Keracoll product line. I’m familiar with some products (I’ve used them at work), but H40 Eco Marmorex glue remains a mystery. I couldn’t find the video on the Internet; the technical information is presented scatteredly and contradictory. Maybe someone has a selection of information on this product, please share, I’ll remember with a kind word.
Due to interest in H40 Eco Marmorex , a detailed description has been added to the website.
This product has unique characteristics and it is difficult to find analogues. Due to the significant cost, it is delivered to order. Video material on the product has not yet been publicly available.
I have a branded video from the Kerakoll company, although the resolution is rather weak, so we won’t post it on the site. I can provide it to you upon request (write to me in the private message module on the site). The video shows in detail the process of cladding a 6-story building with new marble slabs, in Russian. Additionally, we contacted a representative of the Kerakoll company, they confirmed to us that there is video material on the H40 Eco Marmorex. As soon as it is provided, we will post it on the website.
