Dryseal Masonry Waterproofing Cream is a BBA approved, one coat penetrating damp treatment for external brick, block and stone walls. The thixotropic cream penetrates deeply into porous masonry, helping stop rainwater ingress, frost and salt damage while still allowing the wall to breathe. Supplied in 3 litre tubs, it is easy to apply by brush, roller or spray and dries clear with no change to the natural appearance. Typical coverage up to 15m² per tub depending on surface porosity.
