A ready-to-use, high-performance acrylic primer enriched with fine quartz filler (up to 40 µm), specially formulated by Kraski Breez to create an optimal adhesive interface between mineral substrates and decorative or leveling finishes—both indoors and outdoors, including façades and wet areas.
Primary Functions
✔ Significantly enhances adhesion between substrate and subsequent layers
✔ Creates a micro-rough, matte “keying” surface ideal for thin-layer decorative plasters (microcements, structural plasters, etc.)
✔ Acts as a temporary protective layer for walls during winter pauses in construction
✔ Can serve as a standalone base coat in select applications
Mandatory in all professional systems involving Kraski Breez decorative plasters.
Key Properties
- Eco-friendly — safe for people and environment
- Vapor-permeable — does not form a film; preserves wall “breathability”
- Antibacterial
- Odor-resistant
- High density & optimal viscosity — easy trowel or roller application
- Minimal splatter, uniform coverage
- Excellent bonding to mineral substrates
- Dries to a matte, slightly abrasive surface—perfect for mechanical adhesion

Tinting
- Can be tinted to light, unsaturated tones to harmonize with the final finish
- Use compatible tinting pastes; always test for stability before full application
Surface Preparation
Substrate must be:
• Dry
• Clean
• Structurally sound
• Free of dust, grease, and loose particles
❗ Mandatory first step: Apply Universal Deep-Penetrating Primer WD-AC-007 before WD-AC-558.
