There is no use to damp-proof and re-paint when there's still damp trapped inside a wall.
Introducing Damp-Vent - A Simple & Cheap Ventilation Solution to accelerate the drying out of walls - and cause no further damage.
Do you have rising damp in your walls? Experts will probably advise you to strip your plaster and replace the DPC in your wall. Stripping the plaster not an option? There is an easier way. Less hassle, and only a fraction of the price. Damp-Vent plugs are a viable way to slow down wall damage and prevent the problem from getting out of hand. It not only provides a practical solution to a growing problem, but also negates the need for re-plastering and repainting your entire wall.
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 ideal height is 300mm from the bottom of the wall.
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.
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!
In short, rising damp on interior walls is a build up of internal moisture. This moisture shows through the plaster and paintwork. When the problem gets more severe, it shows up as wet patches on your wall. The building industry is booming worldwide. But many contractors take short cuts and don’t ensure proper foundations. There are also lots of old houses, so the rising damp home owners see is subtle, but fairly common.
Is your wall or foundation compromised for some or other reason? It may be because your home was built a long time ago. It may also have been built in a less-than-adequate manner by an amateur contractor. Whatever the reason, rising damp happens all the time. Some of the worst cases of rising damp has ever seen occur because of water that travels up from the ground and into your wall. When this happens, no amount of paint can hide the problem for long.
Moisture in your wall is likely to have a snowball effect of damage. It spreads slowly throughout your entire wall and will eventually affect other areas of your home. You can try and paint over it, but eventually it will show through. There are really only two ways to treat this issue: You could strip your entire wall and replace the DPC, or you could use Damp-Vent supplied plugs and air the moisture out of your walls. Which one sounds easier—and cheaper—to you?
