How to repair a moist/damp wall

Posted by Qarah ICT on May 20th, 2021

Rising damp is the word given to high water content on the building wall that rises from the ground. This is often characterized by a wave of waves and white salt powder deposits. It can cause wallpaper to peel and plaster for bubbles.

Signs increased Damp

• The wall caused by a moist rising often smells musty.

• The painting becomes moist with expansion and blisters at the bottom of the wall.

• peeling wallpaper, colouring wall cover and blistering paint.

• Plaster without colour & fractions.

What is the reason for the moist increase?

• Moist proof courses (D.P.C) are plastic layers built into the original brick on the ground to avoid moisture from rising on the wall. The layer is wrongly placed sometimes or not even placed at all by the builder, allowing water to find the way up.

• The land level on the exterior side may be higher, and above the damp holding course, it allows water to penetrate.

• The leaking pipe above the damp continued course can cause moist increases.

• Paintwork is terrible on the exterior side, and that allows water to penetrate the walls

• Houses with wooden floors often have the lower floor respiratory system. When this wood floor is replaced with concrete floors, the results on the floor cannot be ventilated so that the water rises.

Now, after you learn to identify reasons for increasing humid, you will be able to fix some problems using the following steps:

Drying wall

• Use the industrial gas dryer to the drywall and let it run for 24-48 hours.

• Remove the moist plaster and drill 70 mm holes to the wall at a depth of 80 mm, leave 10 mm between holes. Continue this order from the ground to 500 mm above the ground on the side of the wall interior.

• Inject silicon into the hole that has been drilled.

Silicon injection.

There is a need to drill a series of holes as close as 20 mm apart. Holes need to be drilled along the mortar section. These joints can be found by paying attention to the differences in drill dust colours.

That part - a combination of mortal - often soft than brick, which allows you to drill it quickly. You can inject silicon liquid into a hole using the Caulking gun. Silicon will now penetrate bricks and mortars to make moist resistant courses in the brick.

Cracked wall and joints

Confirm for cracks on the exterior side of the wall and fill with a waterproof plaster.

Check the joints between door frames, door and wall frames. Get rid of damaged sealants and reseal with sealants with waterproof builders.

Waterproof plaster

Crumb The Old plaster from the wall and then made it retired using a waterproof plaster mixture. When you want a waterproof plaster, add a waterproofing additive to the wet plaster and smell before applying it to the wall.
