Dulux Trade Blockfiller Plus

Dulux Trade Blockfiller Plus is a water-based product, which is suitable for interior use on concrete walls and ceilings. Designed to fill surface imperfections in concrete block and poured concrete, to improve the appearance of the substrate. It can act as a finish or a primer for subsequent Dulux Trade finishes. Ideal where minimum downtime and efficiency is required. Caution: This product is designed only for the purpose of filling voids and pores within the surface of the concrete. Topcoats applied over excessive build-up of the Dulux Trade Blockfiller Plus can cause delamination of the filler, resulting in peeling of the topcoat.

Application: Apply a generous coat by airless spray followed immediately by tipping off with a medium pile roller. For airless spray application, we recommend a minimum working pressure of 140 kg/cm² (2000 Ib/sq in) with a spray tip size of 19 thou and a fan of 12 inches. May also be applied by brush, roller or conventional spray. When applying by spray, work into all pores and voids with the first pass, then finish with a full coat. If applying by brush, remove brush marks with a partially loaded roller while the filler is still wet. Do not apply if the surface temperature is below 10°C.
STIR THOROUGHLY BEFORE USE. Do not thin. Concrete Block and Poured Concrete: After surface preparation, apply one coat of Dulux Trade Blockfiller Plus, which can be left untopcoated or finished with an appropriate Dulux Trade paint system. Previously Painted Surfaces: Not suitable for application to previously painted surfaces, unless the surface contains voids and pores large enough to allow application of this filler without excessive surface build.
