Product Description
Mapei Silexcolor Primer is an odourless, silicate based primer to promote bonding and to even out the absorption of the substrate before the final application of coloured top coats from the Silexcolor Range.
Best Uses
Mapei Silexcolor Primer is suitable as a primer coat on cementitious render, lime based render or de-humidifying render. When used in conjunction with Silexcolor coloured finishes, Silexcolor Primer forms a finishing system which guarantees protection of masonry substrates against attack by aggressive chemical products, U.V.
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.
Application
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. Use masking tape to protect adjacent areas not to be painted (fittings, glass, tiles, etc.) to avoid them coming into contact with Silexcolor Primer, as it could stain these materials. While pouring the product, do not use unlined glass or metal containers.Do not dilute. Do not apply As Mapei Silexcolor is odourless and does not contain solvents which makes it suitable for poorly ventilated areas.
The surfaces to be treated must be well-cured, perfectly clean, sound and dry. Completely remove all traces of oil and grease from the surface. Substrates MUST be free of residues of old paint. 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.
