The Damp-Vent plugs prevent further spreading of damp, helping the affected wall to ‘breathe’. Often moisture stays trapped in the wall after treatments like waterproofing. This causes the walls to crack and peel time and again. Installing Damp-Vent plugs lessens the likelihood of plaster and paint peeling further. It also accelerates the drying out of your walls.
No. It won’t be that effective.. The damp in a bathroom is usually caused by a plumbing leak, or from continuous condensation from steam. It can be relieved with sufficient room ventilation or by identifying the leak. Damp-Vent plugs are more effective for rising damp issues, or external penetrating damp, assisting the internal damp in the wall to ventilate, and eventually dry up.
