Paint Direct's guide to damp proof paint

‘Tis the season... for damp! This time of year is the most common time to experience damp conditions in your home. It’s caused by condensation from warm, moist air coming into contact with cold surfaces such as windows and walls. It occurs mainly during the colder months, regardless of whether the weather is wet or dry.

Before we share our roundup of  the best and most popular products to use to treat and prevent mould, be sure to get your property checked by a qualified building surveyor as a paint may just mask a more serious problem.
