rays and damp in general. Transpiration of the substrate remains unchanged, and the product forms a highly decorative and attractive finish on the surface. Silexcolor Primer penetrates deep down into absorbent substrates without forming a surface film, and without altering its water vapour diffusion capacity.
Do not apply the Silexcolor Primer cycle on painted substrates. Silexcolor Primer must always be applied on substrates before applying the final Silexcolor silicate finishing coat. During application, wear suitable protective goggles and gloves.

Mix well prior to use and apply using a brush roller or sprayer. One coat is suitable for good impreganation. Silexcolor Primer can be recoated with Silexcolor Topcoat after 12-24 hours.
