HG Water seal for outside walls

Water seal for outside walls, 1L HG water seal for outside walls prevents rain from permeating external walls. The permeating damp attracts dirt from the air, so that the external walls become dirty. This causes mould and green deposit may start to form on the external walls. If the damp is transferred indoors, mildew patches can form on the interior walls, creating a damp and musty smell. The product has been developed using the latest technology and it remains active for at least 10 years. In addition, it is very simple to apply and allows the wall to continue to ‘breath’. Depending on the porosity of the surface to be treated, one litre of product is sufficient for 2 to 10 m2 of surface area.

Start by cleaning the surface with HG krachtreiniger (product 19). Preferably remove green deposits with HG algae and mould remover. Apply HG water seal for outside walls with a brush, roller or pump spray. Do not treat more than two square metres at once and always work from top to bottom. Apply the product in horizontal strokes from left to right. Always treat the surface with 2 or more coats, until you achieve saturation. It is better to apply 2 thin coats than one thick one. Always apply the different coats of HG water seal for outside walls wet on wet. In other words, the previous coat must not be fully dry before applying the next coat. Do not apply in the sun or on warm walls.
