Before you purchase tile adhesive, you should decide where the cladding will be laid - inside or outside the house. It is also important to know the size of the tiles. It can be large or regular. All this will affect the results of the selection. For ceramics, you can use the simplest compositions. As an exception, there are cases when flexible surfaces are faced like plywood or drywall.
How to choose a ceramic tile adhesive
Before you visit the building materials store, you need to resolve a few issues. For example, look at the base. If the base is subject to temperature changes, this should also be taken into account. As for the decoration of the facade, it is better for him to purchase a frost-resistant composition. The characteristics of such an adhesive will be determined by a set of additives. For finishing pools, you need to choose frost- and moisture-resistant mixtures. If moisture gets under the tile, then the effect on separation during freezing increases several times. Among other offers of the market it is possible to allocate tiledglue "Bergauf". It will be discussed in the article.
Description
The above composition is a highly elastic adhesive for standard and large ceramic tiles. The mixture is also suitable for stone. The adhesive is recommended for outdoor work and interior cladding. The mixture prevents the material from moving off the horizontal surface. The adhesive can be used for underfloor heating, loggias, façades, showers and plinths.
Specifications
Bergauf tile adhesive is prepared using cement, which acts as a binder. It determines the main color. He is grey. For one square meter of the finished surface, 2.5 kg of dry mix will be enough. This is true if the layer thickness is 3 mm. The recommended thickness is equal to the limit from 2 to 6 mm. Tile adhesive "Bergauf" after mixing remains viable for 3 hours in an open container. After application, the open time is 20 minutes. It is possible to correct a tile after laying within 10 minutes. A full set of strength should be expected after 28 days, and after 48 hours it will be possible to walk on the finished surface. Grouting is allowed in a day.
Bergauf tile adhesive can be applied at a base temperature of + 5 to + 25 ˚С. Brand strength is M 100 or higher. You may be interested in compressive or flexural strength. These indicators are equal to 10 and 2.5 MPa, respectively. The adhesion strength to concrete after 28 days is 0.8 MPa. Operation is possible in a wide range from -50 to + 70 ˚С. Tile adhesive "Bergauf Keramik" has frost resistance equal to F 35.
Usage areas
The described adhesive can be used when laying ceramic tiles with an area of 900 cm2. Installation can be carried out on walls and floors. Low-absorbent tiles or porcelain stoneware products can only be laid on the floor, walls are excluded here. The same applies to natural stone. Mosaics, transparent tiles and marble cannot be laid with Bergauf Pro tile adhesive.
The base can be deformable or solid. Laying can be carried out on a warm floor. Critical reasons should not be. The room may have normal or high humidity, masonry in the pools is excluded. The application layer should not exceed 10 mm. The composition is reinforced and suitable for porcelain stoneware and tiles. It is manufactured in accordance with GOST R 56387-2015. For a bag you will pay 236 rubles.
Work conditions
The surface to be finished should be cleaned of oil, dirt and dust, as well as various delamination. There should be no particles interfering with adhesion on the substrate. The surface is covered with a primer of the same manufacturer. In order to achieve the desired result and preserve the properties of the solution, you should follow the instructions. For example, it is important to observe the air temperature when applying BergaufCeramic Pro. This indicator should vary from + 5 to + 25 ˚С.
The required water consumption per 1 kg of the mixture is 0.19 liters. This value can be increased to 0.22 liters. 4.75 liters of water will be enough for a 25-kilogram bag, this volume can be increased to 5.5 liters. The resulting mass must be mixed until it acquires a homogeneous composition. It is important to exclude contact of the solution with the respiratory and vision organs.
Additional recommendations for preparing the base. Reviews
The base before starting work must comply with SNiP 3.04.01-87 and have sufficient bearing capacity. The described adhesive can be used for laying tiles, ceramic tiles and porcelain stoneware exclusively on the floor on cement, concrete substrates and surfaces made of waterproofing cement coatings, as well as cellular concrete. The base can be cement-lime, plastered or covered with putty.
From the reviews of the Bergauf tile adhesive, you can understand that the material is recommended for work on the facade, balcony and plinth. When carrying out work, the heating of the surface should be turned off two days in advance. The inclusion of the floor is possible in a week. The base of the master is recommended to be cleaned, to remove the peeling old coating. For irregularities up to 5 millimeters, an adhesive should be used to seal local irregularities. This must be done a day before gluing the tiles. If the irregularities are greater than 5 mm and do not exceed 15 mm, plaster or putty should be used. This must be done a day before gluing.tiles.
Reinforced tile adhesive "Bergauf", as consumers emphasize, should be applied to the prepared base, which is treated with a primer and dried for 4 hours. If the surface is highly absorbent, the primer should be applied twice. Reinforced concrete, concrete and low-absorbent bases should be treated with "Betonokontakt" and dried for 4 hours. Consumers point out that without a primed coat, poor adhesion of the finish to the substrate and reduced open time can be experienced.
In conclusion
The reinforced tile adhesive described in the article should be prepared using clean tools and in the same containers. The properties of the product can only be guaranteed by observing the proportions of mixing, as well as the procedure for preparing the mixture. So, 0.22 liters of water will be enough for 1 kg. For 5 kg of the mixture, approximately 1.1 liters of water will go. For a 20- and 25-kg bag, you will need 4.4 and 5.5 liters of water, respectively.
The mixture is then stirred until smooth and left for 5 minutes until the chemical reactions are completed. After that, the solution is mixed again using a special mixer for dry mixes. You can use a regular drill with a nozzle. However, the number of revolutions must not exceed 800 per minute.
