Main Highlights

Long-lasting Damp Proofing Protection: An effective brick sealer that gives lasting brick waterproofing protection for interior and exterior brickwork and masonry. The brick sealant is best described as a brick waterproofing sealant, and will continue to work long after application, offering protection from water ingress for up to 10 years.
For Interior & Exterior Use: The water sealant for brickwork is usually applied as a water repellent spray so it becomes a brick sealer exterior. Apart from its use as a brick sealant for exterior applications, the clear acrylic sealer works just as effectively as a brick sealer interior. The clear waterproof sealant can be used on internal and external walls.
High Performance Sealer: The water sealant for brickwork is a brick waterproofer and water sealer that offers lasting protection against water ingress. The brick wall sealer is an effective brick sealant that begins to work as soon as it is dry. It soaks into porous brickwork, sealing the voids to give a protective, water-resistant finish.
Breathable Multi-Use Formulation: The breathable brick sealer waterproofs bricks and masonry and helps prevent moisture build-up inside the home at the same time. Furthermore, the versatile exterior and interior brick sealer can be used on a variety of surface types, including brick walls, cement, concrete, natural stone and masonry facades.
Application & Coverage: Prior to application, ensure the surface is clean and dry. The waterproof brick sealant can be applied by brush or roller, and 5 litres will cover up to 25㎡. For best results, apply 2 coats. Once dry, the invisible waterproof sealant will ensure the brickwork or masonry exhibits water repellent properties when water lands on it.

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+
