Use Mapei Quarzolite Base Coat on old or well-cured new render or as a base layer on old paintwork before applying a finishing coat from the Quarzolite range.
Mapei Quarzolite Base Coat is a ready to use adhesion primer that has been formulated with quartz granules for application as part of a layered system from the Mapei Quarzolite range of products. Quarzolite Base Coat can be used on old render to level out imperfections, or well-cured new render to improve the application and adhesion of the finishing coat.
Mapei Quarzolite Base Coat is supplied in white or can be tinted to a colour similar to the finishing coat to help integrate the final coat, particularly when bright, lively colours are applied which do not usually have good covering properties.
Preparation of the substrate
New surfaces or surfaces patched up with repair 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 Quarzolite Base Coat may be used neat, or diluted with 5 - 10% water. 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 Quarzolite Base Coat in its original container before pouring off the quantity required.
Application of the product
Mix Quarzolite 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 Quarzolite 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 hours. Quarzolite Base Coat may be painted over after 12 - 24 hours.
