Heritage and listed buildings require due care and attention when specifying paint and protective coatings. This is due to the traditional construction techniques and the building materials such as lime based renders natural stone and even cob. Another modern feature often negated from heritage buildings is a damp course. When a modern film forming paint is applied to the fabric of a heritage structure without a modern damp course, moisture becomes trapped in the substrate leading to issues with damp. The knock on effect of this damp is the formation of mould which is a health hazard.
Also, the building structure itself can become damaged due to the build-up of trapped moisture content.
Promain have an extensive range of coatings for heritage properties. This range includes highly breathable mineral silicate paints from manufacturers Keim & Mapei. And traditionally formulated internal and external lime washes and linseed oil paints from the Traditional Paint Company.
