Dunlop Damp-Proof Waterproofing is an acrylic brush-on membrane designed to prevent rising damp, efflorescence, and resist negative hydrostatic pressure. It adheres excellently to substrates including brick, masonry, concrete block, concrete, stone, and timber, and can be easily applied using a brush or roller. Once cured, it can be overcoated with most decorative paints.

Surface Preparation: Ensure all surfaces are structurally sound and free from existing coatings, adhesives, and efflorescence to achieve maximum bond strength and resistance to hydrostatic pressure. Surfaces may be damp but not wet and must be cleaned free of dirt, grease, oil, or other contaminants. Fill holes and non-structural cracks with a suitable floor repairer before application.

Application Instructions:

  1. For Floors: Spread the material using a brush or long nap roller to achieve coverage, then finish with a long nap roller.

  2. For Walls: Apply using a brush, roller, or spray, ensuring even coverage.

  3. Work the material into voids to avoid pinholing.

  4. For areas affected by hydrostatic pressure, apply a minimum of two coats. The second coat can be applied after 4 hours. Ensure uniform coverage and the required dry film thickness per coat.

Coverage:

  • Single Coat: Approximately 3m² per litre, per coat, when used as a barrier to efflorescence or as a moisture-resistant coating over green concrete.

  • Multiple Coats: For areas with hydrostatic pressure, two coats are required at a coverage rate of 1.5m² per litre per coat. Additional coats may be necessary to achieve uniform coverage.

Drying Time: Allow the membrane to cure for 24 hours before applying adhesives, mortars, decorative coatings, or other surface treatments. Ensure the membrane is not damaged during subsequent treatments. For floor surfaces, allow the final coating to cure for at least 24 hours before further treatment to minimize the risk of mechanical damage.

Clean Up: Wash all equipment with water or a water/detergent mixture immediately after use.
