CEMIX® BRICK & BLOCK SEALER is UV stable, eco-friendly, non-toxic water repellent non-flammable water-based penetrating & film-forming repellent treatment that will protect concrete and masonry from water and chloride intrusion while still permitting water vapour transmission. It can be successfully applied on slightly damp but surface dry substrates. The application does not produce any discolouration of the surface and is suitable for weatherproofing and sealing a wide variety of absorbent surfaces including cementitious roof tiles.
The brick, block or roof tile surfaces should be water blasted and made clean, free from grease, loose particles, dirt, paint, curing compounds etc. Moss or algae growth should be removed with a suitable treatment and washed with clean water.
Shake or stir thoroughly before use. Always test apply on an area first to approve the look and feel. CEMIX® BRICK & BLOCK SEALER should be applied without diluting in two coats to ensure complete coverage and saturation of the surface. Apply with garden sprayer, roller or brush. *Depending on the porosity of the substrate – coverage of approximately 5m2 – 14m2 per litre can be achieved.
Before applying any sealer on a fresh concrete, ensure a minimum of 28 days for curing.
