Interior Spray Cork for Damp & Mould
A thin breathable cork layer that warms cold internal walls, stops condensation forming and can be painted over like plaster.
The problem
Why this matters
Cold external walls inside the home form condensation, which leads to black mould, damp patches and ruined decor. Standard insulated plasterboard eats 50–80 mm of room width and is invasive.
Our solution
How we fix it
We spray a 2–4 mm cork coat directly onto your interior wall. It raises the surface temperature above dew point, allows moisture vapour to pass through, and gives you a smooth finish ready for paint or wallpaper.
What you get
- Stops condensation and mould at the source
- Adds <5 mm thickness — no room loss
- Breathable, ideal for solid-wall homes
- Paintable, wallpaperable, sandable
- No skirting, sockets or coving to remove
- Completed room-by-room with minimal disruption

Common questions
People often ask
- Will mould come back?
- Once the wall surface stays above the dew point, condensation can't form — and mould has nothing to feed on. Combined with normal ventilation, the problem stops.
- Can I decorate over it?
- Yes — emulsion, wallpaper or even tile adhesive bond to it normally.
- How long does a room take?
- A typical bedroom is one day including prep; a whole house can be done over a week.
