HUMI-BLOCK is a filler coating solution for walls damagad by dampness. It blocks water while keeping the substrate water vapour permeable. It prevents ugly, defective and decorative coatings deterioration associated with dampness flooding and water ingress.
Over exterior walls : HUMI-BLOCK operates as a dampproof filler, which blocks water penetrating the surface of the substrate.
