Mapei Silexcolor Base Coat

Mapei Silexcolor Base Coat is an initial masonry coat formulated to even out surfaces by filling defeats on old render prior to a top coat of Mapei Silexcolor Mineral Silicate Masonry Paint.

Best Uses

Mapei Silexcolor Base Coat is best used as a base filling layer with quartz granules for dehumidifying render before applying layered finished materials from the Silexcolor range. Silexcolor Base Coat is indispensable when scratch effect finishes are applied, to avoid the substrate showing through the more transparent part. Silexcolor Base Coat may be used to even out the surface, by creating an even finish and by covering small imperfections. When applied in white, or in a colour similar to the final coat, it helps to integrate the final coat particularly when bright, lively colours are required via the top coat.

Surfaces treated with Silexcolor Base Coat have a uniformly rough finish, which makes it easier to apply layered finishing materials, particularly when applied by trowel. This results in a more even distribution of the finishing material over the entire surface.

Mapei Silexcolor Base Coat is the second stage of the Silexcolor masonry paint Range, compromising of Mapei Silexcolor Primer, Mapei Silexcolor Base Coat and Mapei Silexcolor Top Coat.

Application

Preparation of the substrate
New surfaces or surfaces repaired with touch-up mortar must be cured, perfectly clean, sound and dry. Remove all traces of oil and grease and parts which are not well-attached from the surface. Seal any cracks which are present and repair any deteriorated areas. Seal off the porosity and smooth off any uneven parts in the substrate.

Preparation of the product
Silexcolor Base Coat may be used neat, or diluted with 5-10% water or Mapei Silexcolor Primer. Make sure that the product is well blended, and use a low speed drill if possible for blending. If only a part of the product is to be prepared, mix the Silexcolor Base Coat in its original container before pouring off the quantity required.

Application of the product
Mix Silexcolor Base Coat well before use, and apply it using conventional techniques with a brush, a roller or by spray (air mix). A single coat of Silexcolor Base Coat is usually sufficient to prepare the substrate. However, if the substrate is particularly uneven, a second coat may be required. Protect from rain for at least 12-24 hours. Silexcolor Base Coat may be painted over after 12-24 hours.
