Seal a brick wall?HG water seal for outside walls is a brick wall sealer that prevents moisture from permeating the façade. The moisture attracts dirt from the air, so that the walls become dirty and mould starts to grow. Luckily, with HG water seal for outside walls this is a thing of the past!
Moisture in masonry causes mould and algae on the brick exterior. If the damp is transferred indoors, mildew patches can form on the interior walls, creating a damp and musty smell. Using a waterproof brick wall sealer on the outside walls is thé perfect solution. Our masonry sealer for outside walls has been developed using the latest chemical technology and remains active for at least 10 years. In addition, our waterproof brick sealer is very simple to apply and allows the wall to continue to ‘breathe’. Depending on the porosity of the surface to be treated, one litre of brick sealer is sufficient for 2 to 10 square metres of surface area.
