Sealing your walls with an external masonry water repellent cream will not only prevent water penetration but it will also preserve the life of the masonry. We have used many of the products available and only use the highest quality. masonry water repellent cream is absorbed into the substrate by up to 18mm this provides far better protection and durability than any topical silicone water repellent.

Coastal Wall Ties are approved contractors of Secotherm masonry water repellent. Secotherm is a great product that can be applied to most substrates providing they have not been painted and is guaranteed for 20 years.
