Plastering Specialists

Plastering after damp problems requires specialist techniques and plaster . Standard plasters, such as Carlite, should not be used after a damp treatment as they cannot prevent the migration of hygroscopic salts. Failure to apply a salt retardant plaster after treatment is the most common cause of continuing after a remedial damp proof course has been installed.
