Primer for mineral surfaces RILAK Kvarc A 0.9 L

RILAK Kvarc A 0.9 L is a water-based primer formulated for mineral surfaces. It is intended to improve adhesion and create an even, slightly textured substrate on concrete, cement, lime and gypsum plasters and other mineral-based substrates. Suitable for both interior and exterior use, this primer reduces surface absorbency and promotes uniform coverage of subsequent paints, decorative renders or textured finishes.

Advantages

RILAK Kvarc A provides consistent surface sealing that reduces patchiness and paint consumption on porous mineral substrates. Its formulation improves mechanical bonding between the substrate and the finishing coats, helping to prevent peeling and uneven appearance. The primer dries to a stable, slightly granulated film that evens out minor differences in porosity and supports better workability of topcoats.

Suitable for

• Preparation of concrete and cement surfaces before painting
• Sealing plaster and render to reduce absorbency
• Priming interior and exterior walls prior to decorative finishes
• Improving adhesion for paints, textured coatings and thin-layer renders

Key specifications

• Volume: 0.9 L
• Type: water-based primer for mineral substrates
• Application surfaces: concrete, cement, lime and gypsum plasters, mineral renders
• Effect: reduces absorbency and evens substrate porosity
• Usage: suitable for interior and exterior application
• Appearance after drying: stable, slightly textured sealing layer

How to use

Ensure the substrate is clean, dry and free of dust, loose particles, oil or salt efflorescence. Stir the primer thoroughly before use. Apply one even coat by brush, roller or low-pressure sprayer, keeping an even wet edge to avoid lap marks. Allow the primer to dry fully according to ambient conditions before applying paint or finish; drying times depend on temperature and humidity. For highly absorbent surfaces a second coat may be applied to achieve uniform sealing.

Usage recommendations

Store and apply at recommended temperatures; protect from frost and direct sun during application. Test a small area before full application when working over substrates of unknown composition or on previously painted surfaces. Follow safety instructions on the product label and allow full curing of the primer before decorating.
