Universal Acrylic Deep-Penetration Primer (Concentrate) WD-AC-007
High-Efficiency 1:4 Concentrate – The Smart Professional Choice | Kraski Breez
Purpose & Key Features
Primer WD-AC-007 (Concentrate) is a highly concentrated, water-based acrylic impregnation engineered for deep strengthening and professional preparation of porous mineral substrates—before applying plasters, paints, spackling compounds, tile adhesives, and more.
Delivered as a 1:4 concentrate (1 part primer + 4 parts water), it offers exceptional cost and logistics efficiency without sacrificing performance:
- 1 kg of concentrate yields up to 5 kg of ready-to-use primer
- Reduces transport weight and packaging waste by up to 80%
- Lowers material costs by 60–70% compared to pre-diluted alternatives
Once diluted, it delivers identical performance to the standard WD-AC-007: optimal fluidity, deep penetration, and uniform substrate stabilization—even on highly friable surfaces.
Key Characteristics
- Deep penetration – binds dust and reinforces substrate from within
- Equalizes absorbency – prevents uneven drying and reduces topcoat consumption
- Eliminates “hungry” and “greasy” spots – ensures consistent adhesion
- Eco-friendly – water-based, solvent-free, low environmental impact
- Odour-neutral – ideal for homes, clinics, schools, and public spaces
- Concentrate format – compact storage, on-demand preparation, extended shelf life
Applications
Suitable for interior and exterior use on:
- Aerated and foam concrete
- Silicate and ceramic brick
- Clinker, slag, and ceramic blocks
- Concrete slabs
- Cement- and gypsum-based screeds
- Cement and gypsum plasters
Recommended before:
- Water-based paint application
- Spackling and levelling
- Decorative plaster systems
- Ceramic tile installation
Approved for use in:
- Residential and children’s rooms
- Hospitals, schools, and clinics
- Restaurants and administrative buildings (Classes A, B, C)
Preparation & Application
Dilution:
- Mix 1 part concentrate with 4 parts clean water (1:4 by volume)
- Stir thoroughly until homogeneous
Surface prep:
- Must be clean, dry, sound, and free of loose particles
Application:
- Apply with roller, brush, or spray equipment
- 1 coat is usually sufficient; 2 coats for highly porous substrates
- Allow full drying before next step
Consumption (of ready-to-use primer):
- 0.1–0.3 kg/m², depending on substrate porosity
Technical Data
- Dilution ratio: 1:4 (concentrate : water)
- Yield: ~5 kg ready primer per 1 kg concentrate
- Drying time (+20°C, 65% RH):
- Tack-free: 2 hours
- Dry to touch: 24 hours
- Full cure: 28 days
- Shelf life: 12 months in sealed original packaging
Advantages of the Concentrate Format
- Lower logistics costs – lighter, smaller volume
- On-demand mixing – prepare only what you need
- Longer shelf stability – concentrate degrades slower than ready mix
- Significant savings – up to 70% more economical than ready-to-use primers
Why Professionals Choose WD-AC-007 Concentrate
This isn’t just a primer—it’s a smart material strategy. By combining maximum performance, environmental responsibility, and economic efficiency, it delivers a rock-solid foundation for any high-quality finish—whether in a family home, a luxury boutique, or a large-scale commercial project.
