Product Overview
Berger BP Cement Primer (Anti-Alkali) is a high-quality water-based interior wall primer specially formulated for cement plaster, concrete, and masonry surfaces. It penetrates deeply into the substrate, sealing porosity and creating a strong bonding layer for topcoat paints. Designed with anti-alkali resistance, this primer prevents surface deterioration caused by alkaline salts and moisture migration from cement-based walls. BP Cement Primer improves paint adhesion, enhances topcoat finish uniformity, and reduces paint consumption, ensuring longer-lasting and visually superior wall finishes.
Key Benefits
Anti-Alkali Protection
Prevents alkali attack from cement surfaces, reducing paint peeling, blistering, and surface degradation.
Improved Paint Adhesion
Creates a strong bonding layer between wall surface and paint, ensuring long-lasting coating performance.
Seals Surface Porosity
Penetrates porous surfaces effectively, reducing uneven absorption and improving finish uniformity.
Enhanced Paint Coverage
Reduces paint consumption by providing a stable base, improving spreading and coverage of topcoat paints.
Smooth Base Preparation
Provides a uniform surface that enhances final paint appearance and finish quality.
Easy Brush & Roller Application
User-friendly formulation spreads smoothly and evenly with standard painting tools.
Recommended Applications
- Interior cement plaster walls and ceilings
- Concrete and masonry surfaces
- Surface preparation before applying interior emulsions and distempers

Application Process
1. Surface Preparation
Ensure surface is clean, dry, and free from dust, grease, oil, loose particles, or previous flaking paint. Repair cracks and damaged areas using suitable fillers. Newly plastered surfaces should be fully cured before primer application.
2. Dilution
Stir the primer thoroughly before use. Dilute with clean water as recommended to achieve proper application consistency.
3. Primer Application
Apply one uniform coat using brush, roller, or spray equipment. Ensure complete and even coverage across the entire surface. Avoid over-thinning or excessive spreading.
4. Drying
Allow the primer coat to dry for approximately 4–6 hours before applying putty or topcoat paint. Drying time may vary depending on humidity and weather conditions.
5. Painting
After primer drying, apply wall putty (if required) and proceed with recommended interior paint system for best results.
