PL-PRIMER is a concentrated liquid primer, specially develop for preparing surfaces prior to rendering. It provides hydrophobic properties to the substrate, eliminating the risk of strength decrease of the render due to water loss. PL-PRIMER does not form a skin, therefore it does not affect the render’s adhesion to the substrate or the vapor permeability of the structure. PL-PRIMER is applied thinned with water to absorbent substrates to be rendered, including brick walls, lime stone, aerated or gas concrete, etc. preventing water loss from the render to be applied. Especially for MARMOCRET color renders, the use of PL-PRIMER is necessary to achieve uniform color over the entire surface. In this case PL-PRIMER is applied to the substrate of the colored render (rendering, concrete, etc.).
PL-PRIMER is diluted with water 1:3 up to 1:4 by volume, depending on the absorbency of the render’s substrate. It is applied by brush or spray to a clean substrate. The primer should dry before rendering.
