Application Procedure
Preparation of substrate
The substrate should be dry, clean, and free from grease, oils, residual paint, and other loose material. In each case, the manufacturer’s recommendations for gypsum-plaster must be followed, particularly as far as moisture content and level of surface finishing are concerned. Cracks in concrete surfaces must be repaired with Epoinject. Anhydrite surfaces must be sandpapered.
Preparing the product
Ready to be used.
Applying the product
Stir the PRIMER AC before use; spread it uniformly on the surface with a flat brush or roller without diluting it. If the gypsum plaster surface is particularly smooth and glossy, it is recommended to rub it beforehand. Once it has dried, install the tiles.
