easy to apply, dries very fast in a sunny day - we have the sealer about a month on the roof and so far the seal looks pretty good - we did 2 layers of seal

By Maria F From Killarney

Recently used product to seal my Kent peg tile roof as tiles had become porous and covered in moss etc. The roof now looks great and the rain runs completely off leaving the tiles dry in no time. Great product and brilliant company to deal with.
