Breathable Brick Sealer & Waterproofer (5 Litre)
Floorseal Premium Surface Sealers & Cleaners

Breathable Brick Sealer & Waterproofer (5 Litre)

Why we love it
  • Preserves historical buildings naturally.
  • Prevents growth, rainwater and damp.
  • Ensures long-lasting protection.
Main Highlights
  • A NATURAL FINISH BRICK SEALER & WATERPROOFER: A powerful water & damp repellent suitable for use on the exterior surfaces of your building. This brick sealer can be applied by sprayer, roller or brush in a single application. Or for very porous surfaces a 2nd lighter application can be applied within 30 mins to 1 hour later. This sealer does not alter the appearance of the treated surface.
  • PERFECT FOR: Sealing porous bricks, natural stone, concrete masonry and pointing creating a water repellent surface. Suitable for use on any building and any form of pointing. This includes rubble filled walls, cavity walls, domestic buildings and commercial buildings. Inhibits organic growth, seals against rainwater and damp. Also seals traditional sand and cement pointing and lime pointing.
  • SUITABLE FOR LISTED OR HISTORIC BUILDINGS: This sealer is non-film forming so does NOT create a non-breathable coating or lacquer. Breathable Brick Sealer & Waterproofer is an impregnating sealer which soaks into the pores of the treated material. This creates a water repelling effect to resist rainwater & damp. The sealer will still allow moisture vapour transmission through the bricks or masonry.
  • COVERAGE & LIFESPAN: Approximately 5m2 per litre when applied to porous bricks, natural stone, flints, lime, slate & concretes. A 2nd light application can be applied to very porous surfaces. Very dense materials may produce a coverage rate of up to 10m2 per litre. Expected lifespan of 10 years+
  • SEE ALSO: Floorseal Interior Brick Sealer & Dustproofer also listed on Amazon for sealing and dustproofing INTERIOR brick walls to prevent dusting.
  • FURTHER INFORMATION: At the foot of the page for further information regarding cleaning and sealing interior and exterior bricks and masonry.

SmartSeal

Climashield Masonry Waterproofing Cream - 1L - Exterior Brick Sealer & Rain Repellent Clear Waterproof Sealant for Concrete, Cement, Mortar, Sandstone, Limestone & Granite. Lasts up to 25 Years

Why we love it
  • Long-lasting masonry protection cream.
  • Invisible finish after application.
  • Exceptional customer support available.
Main Highlights
  • Colourless: Climashield Masonry Cream is a waterproofing cream that does not alter the appearance of a surface after application. It dries as a clear brick sealer and forms a rain repellent barrier on exterior walls. The damp proof cream can also be used as a waterproof sealant on many surfaces, such as concrete, stone, cement, mortar and sandstone.
  • Easy to Apply: The clear masonry waterproofing cream dries as a clear sealant and can be easily applied using a masonry brush or roller. Only one coat of the brick waterproofer is normally required and should be applied at a coverage ratio of 5m² per litre. The simple application process for the damp proof cream makes it an excellent choice for DIY enthusiasts.
  • Long-lasting: The damp proof cream and waterproofing sealant can last up to 25 years, and will protect walls against damp penetration without compromising their breathability. Furthermore, the waterproofing cream acts as an additional damp seal that enhances the properties of a damp proof course already protecting brick walls and masonry.
  • Improves Thermal Efficiency: The waterproofing cream can help to lower heating bills by improving the insulating properties of external walls by making them water repellent. The damp proof cream can also help improve the thermal efficiency of cavity wall insulation by keeping external walls dry and inhibiting moisture build-up inside the home.
  • Breathable Technology: The brick waterproofing sealant allows walls to breathe and dry naturally, which helps to prevent the build-up of damp inside a home. Once applied, the waterproof coating blends seamlessly with existing surfaces, providing a breathable water seal. Any excess moisture is slowly released through the breathable clear coat.
