In construction projects, fair-faced or bare concrete surfaces are structurally smooth, glossy, and low in porosity. When gypsum or cementitious plasters are applied directly onto these slick surfaces, the fresh mortar fails to find a mechanical key to anchor into, leading to severe sagging, blistering, and eventual total debonding due to gravity. Similarly, if surface absorption is not checked on exterior walls, the substrate rapidly drinks the moisture from topcoats and decorative renders, leading to excessive material waste and visual imperfections.
The Solution: Mineral-Filled and Acrylic Smart Primers
Eliminating surface slickness and managing absorption variability is the absolute safety insurance of any job site:
- Interior Fair-Faced Concrete Preparation: To lock gypsum, lime, or cement renders onto fair-faced walls and ceilings, the single-component, mineral-filled polymer dispersion DAUGUARD B-PRIMER must be used. It creates a highly textured, rough mechanical grip on the concrete while safely reducing substrate porosity.
- Pre-Decorative Exterior Render: On highly absorbent exterior walls, integrating the acrylic emulsion-based, filled DAUGUARD D-PRIMER optimizes surface readiness. By safely lowering the consumption of expensive final coatings and paints, it secures budget efficiency and perfect visual uniformity.
