Frequently Asked Questions
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.
Damp-Vent will start working immediately after installation, but results will take time. It can take a couple of months up to a year depending on the type of walls.
You require a Rotary Hammer Drill & 40mm SDS Max Masonry drill bit (recommended). The 40mm SDS Core bit will also work. This can be hired from most Tool Hire Shops.
Drill into the centre cavity of the wall between the front and back layers of bricks (+/- 140mm). If there is no cavity, drill straight through the wall, and fit the plugs on either side. If it's not possible to drill straight through, drill halfway through and fit the plug/s on one side only.
Depending on the severity of your damp, the ideal spacing between plugs is 300-500mm apart. The suggested height is 300mm from the floor (or can be placed at height where damp is most prominent).
Vents need to be installed directly into the problem damp area. We also recommend that Vents are placed at least 1000mm past the damp area, with 300mm gaps between vents.
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.
They last for a very long time. You leave the plugs in the affected wall/s indefinitely. You can see it as a wall fixture. As long as the plugs are in, the damp will be ventilated.
Most definitely. Works well on exterior walls, and the plugs have a seal preventing rainwater/sprinklers and insects from penetrating it, yet at the same time providing damp ventilation.
Yes, it would work. Nutec houses are made from fiber cement boards. The plugs will provide damp ventilation.
Yes, it will provide damp ventilation in stone walls.
It only comes in a light beige color, which can be painted the same color as your wall (just don’t paint over the top ventilation hole).
It does not matter, you just have to drill straight through – and insert one plug on each side.
DIY Installation Guidelines
Builders Tip: When building a new wall, use a 40mm pvc pipe as a template for the Damp-Vent holes to avoid having to drill afterwards!
