Dulux Trade Drywall Primer Sealer - White - 10 Litre

Dulux Trade Drywall Primer Sealer is a high-performance, water-based primer designed to prepare interior drywall and ceiling surfaces for a flawless topcoat. Formulated to even out surface porosity, it ensures consistent paint absorption for a smooth, professional finish with excellent opacity. This primer effectively binds and seals powdery or porous surfaces, creating a stable base that enhances durability and coverage of subsequent coats.

Easy to apply and quick-drying, it’s ideal for both new builds and refurbishment projects with new or bare drywall, where a reliable, uniform finish is desired.

• Evens out drywall porosity for uniform coverage
• Binds & seals powdery or unstable surfaces
• Perfect 1st step for a smooth finish with high opacity
• Suitable for interior drywall & ceilings
• Water-based formula for easy application & low odour

Surfaces must be sound, clean and dry.

• Remove all loose and defective paint. Special precautions should be taken during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead.
• Any surface defects should be filled with the appropriate Polycell Trade Polyfilla.

For best results, ensure the surface to be painted is sound, clean, and dry (new surfaces, particularly, must be dry). It is recommended to test a small area of the surface to be painted to ensure compatibility and that you are happy with the finished results.

• Stir thoroughly before use.
• Apply Dulux Trade Drywall Primer Sealer on new or bare surfaces by brush, roller or spray.
• Allow 2-4 hours before recoat. Once dry, apply your top coat. The normal finishing process is 2 coats of a recommended Dulux Trade emulsion.

Spray Recommendations: Airless Spray: For best results use a 517 Low Pressure tip @ 1300 - 1500 psi. (90 – 103 bar). Alternatively, use a 517 tip @ 2000 – 2400 psi (138 - 165 bar). Please note that the above recommendations are intended as a guideline only and some adjustments may need to be made to accommodate equipment type & age, substrate type and individual site & atmospheric conditions.
