Black mould on walls in an Irish home — condensation causes mould in corners and on cold walls

Black Mould on Walls — The Permanent Fix

Painting over black mould doesn't fix it — it comes back because cold walls keep producing condensation. VIPEQ breathable cork coating warms the wall surface so the moisture stops forming and mould cannot return.

Why It Keeps Coming Back

Why Black Mould Keeps Returning on Irish Walls

Most people scrub black mould off or paint over it — and within weeks it's back. That's because the mould isn't the problem. Condensation is.

Cold walls in Irish homes drop below the dew point of the air inside. Moisture condenses on the surface and creates the damp layer that feeds black mould. Until you warm that wall, the cycle never ends.

Anti-mould paints, bleach and dehumidifiers treat symptoms. VIPEQ treats the cold wall — the actual cause.

Common Black Mould Locations

Bedroom corners and behind wardrobes
North-facing external walls
Bathroom walls and ceilings
Solid-wall terraced and semi-detached homes
Ground floor rooms in older properties
Rental properties with inadequate heating
Heritage and stone cottage walls
Newly built airtight homes with poor ventilation
The VIPEQ Approach

Warm the Wall — Stop the Mould Permanently

VIPEQ trowel-applied cork is applied directly to the internal wall surface. Cork is a natural thermal insulator — it raises the wall surface temperature above the dew point so condensation stops forming entirely.

Crucially, cork is vapour-permeable — moisture can still escape through the wall rather than being trapped. This is the correct approach for solid-wall Irish homes where sealing the wall causes greater problems.

Raises wall surface temperature above dew point
Condensation stops forming — mould has no moisture
Breathable — does not trap moisture in the wall
One application lasts 20+ years
Works on internal walls in any room
Natural, non-toxic cork material

Important Note on Damp

VIPEQ trowel-applied cork is effective for black mould caused by surface condensation — the most common type in Irish homes. It is not a treatment for rising damp or penetrating damp from structural defects. If you are unsure of the cause, we recommend an assessment before specifying any treatment.

"We had persistent condensation and mould on the north-facing bedroom wall for years. After VIPEQ Thermal Corkspray was applied, the wall stays noticeably warmer and we haven't had a single damp spot since."

Declan Murphy

Homeowner — Wicklow

"I had two rented terraced houses with bad exterior render — cracked, patchy and leaking in a couple of spots. The corkspray sorted the facade, improved the look completely, and the tenants have commented on the warmer walls."

Siobhán Brennan

Landlord — Cork

"Old stone cottage on the west coast — we were losing heat through the gable wall badly. The breathable corkspray was important to us as we didn't want to trap moisture. Very happy with the result."

Tom Gallagher

Homeowner — Mayo
