For treating penetrating damp externally (eg for direct rain penetration) we recommend a water repellent treatment.
-Water repellent applied to external walls - We use STORMDRY Water Repellent Cream for the protection of external masonry from penetrating damp and freeze thaw
damage.
It prevents rain penetration into masonry materials by lining their pores rather than blocking them – allowing the masonry to continue to breathe naturally.
Unlike waterproof paints or waterproof coatings, STORMDRY retains the natural finish of the masonry so is particularly suited for application to brickwork or
stonework.
Typical applications of Stormdry include:
Protection against penetrating damp.
Improving thermal efficiency of masonry keeping it dry (Energy Saving)
Maintaining thermal properties of cavity wall insulation
Improving flood resistance of masonry.
