Why Plaster Choice Matters in Damp Homes
When damp proofing or tanking has been carried out, choosing the right plaster is just as important as the treatment itself. In Wigan homes, we often see damp returning simply because the wrong plaster was used.
Standard plaster can trap residual moisture and draw salts back through the wall, leading to peeling paint, tide marks, and mould. That’s where breathable plaster systems make all the difference.
Standard Plaster: The Limitations
While standard gypsum-based plaster is fine for dry walls, it’s not suitable after damp work. Problems include:
-
❌ Absorbs and holds moisture
-
❌ Attracts salts that leave unsightly marks
-
❌ Can fail within months of damp treatment
-
❌ Often leads to repeated decoration costs
Breathable Plaster: The Better Choice
Breathable plasters are specifically designed to let walls dry naturally after damp treatment. Benefits include:
✅ Allows moisture vapour to escape
✅ Resistant to salts left behind by rising or penetrating damp
✅ Creates a longer-lasting, healthier finish
✅ Reduces the risk of mould growth on wall surfaces
We source breathable plaster products from trusted suppliers like Builders Super Store, ensuring quality and durability.
When to Use Breathable Plaster
Breathable plaster is essential after:
-
Installing a new damp proof course (DPC)
-
Applying tanking or waterproof coatings
-
Removing contaminated or salt-laden plaster
-
Treating condensation and mould-prone walls
