Thistle DriCoat

Thistle DriCoat

A cement-based undercoat plaster for re-plastering after the installation of a damp-proof course

Thistle DriCoat is intended for re-plastering after the successful installation of a new damp-proof course (DPC). Walls which have had defective damp proof courses (or none at all) are likely to contain hygroscopic salts, which can continue to be a source of dampness, even after rising damp is prevented, because they absorb atmospheric moisture. Thistle DriCoat is cement-based with waterproofing additives, which restrict the migration of these salts from the background through the plaster and helps to limit any detrimental effect on internal decoration.

Thistle BoardFinish is the recommended skim finish plaster for use over Thistle DriCoat.
