When dealing with damp issues in Bolton homes, the job doesn’t end once a new damp proof course (DPC) has been installed. One of the most overlooked yet critical steps is the plastering that follows the damp proofing work.
Why Plastering After DPC is So Important
Old plaster often contains hygroscopic salts that absorb moisture from the air, even after the wall has been successfully treated. If this plaster is left in place, it can cause future signs of damp and damage — even though the DPC is functioning correctly.
This is especially common in homes across Bolton where bridging plaster extends down to the floor or sits in contact with moisture-bearing masonry.
The Role of Vapour-Permeable Plaster
To prevent future problems, we apply a vapour-permeable plaster system that allows the wall to breathe while resisting moisture and salt migration. This ensures the treated wall remains dry and stable in the long term.
At Weather Wise Solutions, we often recommend and install PAM Ties plaster systems, which are specially designed for use after damp proofing. These plasters offer an excellent barrier while maintaining internal air flow — key to keeping your home warm, dry, and healthy.
Key Benefits of Using the Right Plaster System:
-
Prevents salt contamination
-
Allows wall to dry out properly
-
Avoids reintroduction of bridging effects
-
Provides a clean, smooth finish for decoration
Do All Damp Jobs Need Replastering?
Not always. If the original plaster hasn't been contaminated or is not bridging the DPC, removal might not be necessary. At Weather Wise, we always assess this during our visit and provide honest, tailored advice based on your home.
