Ronseal 36285 Thompsons Water Seal 2.5 Litre RSLTWSEAL25L

Utilises hydrophobic technology to deliver invisible protection against water damage.
Deep penetrating formulation that travels deep into exterior dry porous surfaces to form a breathable membrane
allowing moisture vapour inside the substrate to evaporate whilst protecting against water penetration and damage.
A unique formulation which, unlike some waterproofers, penetrates the surface therefore waterproofing even after the initial beading is gone.
Will not be destroyed by ultraviolet light and is long lasting even under heavy moisture conditions.
If application instructions and coverage guidelines are adhered to it provides effective water repellency for years.
Suitable for use on brick, concrete, stone and wood.
For exterior use only.
