Excessive rain and humidity often cause damp patches on walls. The moisture not only attracts dirt, but it also promotes the growth of mould and green algae on the walls! It makes the walls unsightly and if the damp is transferred indoors, mildew patches can form on the interior walls, creating a damp and musty smell. By treating the wall with HG water seal for outside walls, water can no longer penetrate the wall, so problems caused by excessive moisture are unlikely to occur. HG water seal for outside walls has been developed using the latest chemical technology, making it active for at least 10 years after application!
HOW TO USE
- Step 1: Apply HG water seal for outside walls using a brush, roller or pump spray.
- Step 2: Apply 2 or more coatings. The previous coatings must not be fully dry before applying the next coat.
Depending on the porosity of the surface to be treated, 1 litre of product is sufficient for 2 to 10 m2 surface area.
