🧱 Don’t Let the Wrong Plaster Undo Your Damp Proofing
After a new damp proof course (DPC) has been installed, many homeowners are surprised when damp stains or damage return—even with no signs of rising moisture. The culprit? Often it’s the wrong type of plaster.
Standard plasters like gypsum trap moisture and draw salts back to the surface, ruining finishes and making the wall look and feel damp again. That’s why vapour permeable plaster is the trusted solution for post-DPC work.
At Weather Wise Solutions, we use salt-resistant, vapour permeable systems from PAM Ties, following industry best practice as members of the Damp Proofing Association.
🚫 Why Standard Plaster Fails on Damp-Treated Walls
Standard plasters may look fine initially but often cause problems like:
✅ Bubbling or flaking paint
✅ Efflorescence (white salts) reappearing
✅ Cold or damp-feeling patches
✅ Cracked or blown finishes
These issues occur because moisture and salts trapped in the wall have nowhere to escape—so they migrate through the plaster and redeposit on the surface.
🌬️ What is Vapour Permeable Plaster?
Vapour permeable (not breathable) plaster allows moisture vapour to escape from the wall while resisting the re-entry of salts and damp.
Benefits include:
✔️ Prevents salt damage and staining
✔️ Supports long-term wall drying
✔️ Safe for use on traditional and modern builds
✔️ Works with silicone-based DPC systems
✔️ Provides a clean, smooth finish ready for decoration
