Product Description

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 Description

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.

Tips & Advice

1. Preparing the Surfaces

To get the best results, ensure surfaces to be painted are clean, dry and free from all defective or poorly adhering material, dirt, grease and salts. See Dulux Trade Datasheet 448 for full information before use, available free on request by telephoning 0333 222 70 70 or visiting duluxtrade.co.uk. Before surface preparation, read the Health & Safety information about old lead paints.
2. After use

Cleaning After Final Use: Clean brushes and rollers immediately after final use to reuse them for future projects, saving you money and reducing waste. Cleaning Steps: 1. Remove Excess Paint: Scrape off leftover paint into a container for reuse. 2. Wash with Warm, Soapy Water: Clean brushes and rollers with warm soapy water in a sealed container like a bucket or tub. 3. Rinse Thoroughly: Rinse out all soap and paint residues into the same container. 4. Dry Naturally: Let tools air-dry and store in a dry, dust-free area. Dispose Responsibly: Settle Solids: Let paint solids settle at the bottom of the container. Pour off clear water for reuse or disposal. Disposal: Let remaining paint solids dry fully before disposing of them as solid waste. Do not flush paint down the drain, including when cleaning painting tools Pro Tip: Watch this cleaning guide from the British Coatings Federation and Dulux Connect contractor Bagnall’s: https://coatings.org.uk/general/custom.asp?page=HowToCleanPaintbrushes
3. Storing

Storing & Responsible Disposal Do not use or store paint in extreme temperatures and protect from damp & frost. Reuse, Recycle, or Donate- Whenever possible, reuse, recycle, or donate leftover paint. Find local services at recyclenow.com. If no Community RePaint service is nearby, consider advertising paint locally—many good causes need it to brighten community spaces. Dispose Responsibly- Never pour paint or wastewater down drains or sinks. Follow instructions at recyclenow.com to recycle empty packs. Reuse Roller Cages- Remove sleeves and store cages in a dry, dust-free place. Dispose of Unusable brushes and Sleeves- If brushes or sleeves cannot be cleaned or reused, dispose of them in general waste to avoid recycling issues. Paint Wash Water- Collect wash water in a container; don’t pour it into drains or on the ground. Let solids settle, pour off clear water for reuse or disposal, and let solids dry before disposing as solid waste. Do not flush paint down drains, including when cleaning tools.
