This product is best around. Can't fault it at all.

By Martin Gauld From Elgin

Excellent product. Roofs we have used this product on do not get wet and brings back the colour of the tile. Excellent product

By Martin Gauld From From Gutters To Gates

Having continued to use this product I can honestly say it's by far the best out there. The roof stays dry in recent bad weather in the area. Brilliant product.

By Martin Gauld From Elgin

Used the sealer on a roof and I must say it's an awesome product. Customer is absolutely delighted. Will use anything else and also using drive dealers and will be ordering the masonry sealer. 5* product and customer service. Can't rate them high enough

By Martin Gauld From Elgin
