Dryzone Damp-Resistant Plaster is a breathable pre-blended plaster developed to control dampness and salt migration in walls. The plaster is used as part of the Dryzone System for replastering after Dryzone Damp-Proofing Cream or Dryrod Damp-Proofing Rods have been used to create a remedial damp proof course. This highly effective renovation plaster has a porous structure which controls salt migration and allows walls to dry out by evaporation. Suitable for use on salt and damp contaminated walls and provides enhanced salt protection compared with competing products.
