Excessive rain and humidity often causes damp patches on walls. The moisture not only attracts dirt, 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!
