The damp-proofing experts at Prokil were contacted by a client in Amesbury for condensation treatment, as they had spotted dampness and decorative spoiling on a bedroom wall. The problem area was where a chimney breast had been. This was believed to be the cause of the problem.
Our experts investigated the problem, having been told that the chimney breast had been removed at the roofline.
The team found that the decorative spoiling on the internal plaster was due to the historic burning of fossil fuels.
Once the chimney flue was no longer used, there was inadequate ventilation, causing condensation to build up in the flue. This led to salts migrating through the brickwork, which then spoilt the decorative finish of the internal plaster.
Work carried out:
The condensation treatment started with the Prokil team removing the contaminated section of plaster.
We then disposed of the waste plaster before moving on to the next step.
With the affected plaster removed, the next step of our remedial work was to apply a waterproof render to the section of the wall that was affected.
This coat is a specialist render that contains salt inhibitors and waterproofing agents so that areas covered by this render are damp-proofed.
To complete condensation treatment, the team added a skim coat of multi-finish plaster. This specialist plaster is an additional barrier to prevent salts and moisture from accumulating, and seeping through the wall and causing decorative spoiling or mould.
The result of this condensation treatment was a damp-proofed wall section that had two preventative barriers to condensation dampness.
The specialist render will work underneath the damp-proof plaster to prevent salt and moisture from getting through and causing spoiling on the inside of the bedroom.
We left the wall plastered and ready for the client to paint.
