Description
An acrylic-emulsion-based primer for exposed-concrete surfaces, walls and ceilings, that improves the adhesion, working time and workability of gypsum- and cement-based plasters.
Properties
An easy-to-apply primer that improves the adhesion of cement- and especially gypsum-based plaster mortars to exposed concrete on interior/exterior vertical surfaces and ceilings, prevents the rapid water loss of these plasters, and increases their working time and workability.
Application area
Applied to exposed-concrete walls, columns and ceilings before gypsum and cement plaster.
Application method
Before applying, remove all adhesion-weakening oil, grease, rust and paraffin residues; no loose particles. Thin 30–50% with water to the desired consistency, stir 3–5 min to a homogeneous lump-free mix, then apply one coat with a sheepskin roller to the prepared surface. Stir the product periodically during application.
