If you’ve treated rising or penetrating damp in your Skelmersdale home but the walls still look patchy or powdery, your plaster may still be holding moisture or salts.
At Weather Wise Solutions, we’re often called to homes where damp has returned simply because the contaminated plaster was never properly addressed.
Knowing when to repair and when to replace is key to a lasting result.
💧 Why Damp-Damaged Plaster Fails
When water passes through brick or stone, it carries soluble salts that remain behind in the plaster once the wall dries. These salts are hygroscopic, meaning they draw moisture from the air — keeping walls damp even after a DPC or tanking system has been installed.
Common signs of salt contamination include:
-
Persistent damp patches or tide marks
-
Powdery white deposits on the wall surface
-
Paint or wallpaper that won’t adhere
-
Bubbling or flaking plaster
If left untreated, these salts continue attracting moisture, making the wall feel damp long after the original problem is fixed.
🧱 Repair vs Replacement – How to Decide
At Weather Wise Solutions Limited, our specialists carry out moisture and salt testing to determine whether plaster can be saved or needs replacing.
✅ Repair (Salt-Inhibiting Plaster) – Suitable when moisture levels are low and salts are minimal. We apply breathable, salt-resistant coatings that allow the wall to dry naturally.
✅ Full Replacement – Needed when plaster is heavily contaminated, soft, or bridged to the floor. We remove it up to one metre high and reapply breathable, salt-resistant plaster systems compatible with modern DPCs or tanking treatments.
We use trusted materials from PAM Ties and Wycamol to ensure long-lasting protection that keeps walls dry and breathable.
