Damp proof paint isn’t designed for external use – it’s best used internally to protect against damp. Treat your internal walls with anti-mould cleaner and salt neutraliser before redecorating to prevent the reappearance of salt deposits and mould When your external walls are exposed to a water source such as rain, this water can enter your masonry, in some cases travelling laterally from your external walls to your internal walls. Long term, the pollutants in the atmosphere and in driving rain, and storms can affect your home in a number of more serious ways: corrosion, growth of algae and lichen on the walls, loss of structural integrity and damage to timber elements.
