Surface preparation
Cement-based traditional supports should have a sufficient maturity time of (28 days in temperature 23°C and U.R 40%). Supports should be flat, stable and in function of intended use. The support where the product will be applied should be clean and free of external materials, such as: paints, oils, varnishes, anti-adhesion materials. The cleaning is made mechanically or manually. Before the application of the product, the plasters should have a maturity time of at least 1week for 1 cm of thickness. The supports should be mechanically stable, in function of intended use. The surface of the support where the product will be applied should be free of any type of external materials.
Application of product
For a better application of the product, and for a good and uniform spreading of it in the entire surface, it is recommended that you first lay the product on the support through the straight blade of the trowel, and then through its notched part. The product should be applied with a suitable trowel, depending on the type and parameters of the tile. It is recommended that after laying the tile, you put pressure on it so that the back part of the tile gets completely saturated with the adhesive. Special conditions, such as: high temperatures or strong winds, sun or substrates with a high absorption of water, affect negatively the performance of the product and can even decrease significantly the spreading and correction time. To avoid these problems, it is recommended to sprinkle the support with water before the application of the product, or to treat it with the liner DW PRIMER. However, in any case, it is important that before the laying of the tiles, you check if the adhesive has created a “skin”. In such cases, you should re-spread the adhesive in order to re-activate its adhesive strength. You should avoid pouring water over the adhesive which has created a skin (is solidified) because in such as case, an anti-adhesive layer is created. In cases of coatings and floors in outdoor environments, especially in cases when the back part of the tile has relief, it is recommended that you spread the adhesive in the pack part of the tile and also on
the support, so as to avoid the creation of cavities where water can penetrate, or moisture can be created, which can cause the tiles to detach or break.
Storage
