Damp walls can create a number of problems in residential and commercial properties. Not only can it create ugly stains and smelly odors, damp it can also damage the structure of the building over time.
If you happen to have damp walls, it is important to handle the issue properly, so as not to compound the damage. In this guide, we will outline the method and steps for repairing damp walls while using Sakshi Chem Sciences quality products to ensure long-lasting results.

What Causes Damp Walls
Dampness in walls is a common issue usually attributed to water seepage. Water can enter the wall from a few sources: water intrusion, poor waterproofing, or condensation inside the building.
If not treated properly, continued damp problems can result in mold, peeling paint, and a general deterioration of the indoor environment.
Steps to Repairing Damp Walls
Repairing damp walls will not only include a cleaning of the surface but also repairing and addressing the source of the problem, so it doesn’t come back.
Step 1: Removal of Old Plaster
The first step to repairing damp walls is removing the old plaster. Using a hammer and chisel or a plaster removal tool, carefully chip off the plaster from the areas affected by the damp walls.
It is important to do this carefully so you do not damage the brick or concrete underneath. This is important because it allows you to expose the damp areas and assess how serious the damage is.
Step 2: Cleaning the Brick Surface
After the old plaster is off, it is time to clean up the brick surface. Using a cleaning solution of vinegar and water at a 1:1 ratio, scrub the area and any obvious dirt, stains, or bacteria.
The acidic vinegar is effective at dissolving hard water deposits and killing household bacteria, thus ensuring you are cleaning the surface and preparing it for the next treatment.
Step 3: Applying Liquid Rubber Waterproof Coating
Once the brick surface is properly cleaned and dried, it is time to apply a liquid rubber waterproof coating. This liquid rubber will act as a primer by creating a strong waterproofing barrier to support the adhesion of additional layers.
By mixing 1 part liquid rubber with 4 parts water, and then adding 6-7 parts cement to the mixture, you’ll get a smooth slurry. This should be applied to the brick surface using a brush or trowel. It ensures that the wall is moisture-resistant, effectively preventing further moisture infiltration.
Step 4: Applying the Second Coat
After drying the first coat of liquid rubber (within thirty minutes), you can apply a second coat of liquid rubber, while the surface is still tacky.
The second coat will help to strengthen the waterproofing and continue to protect against moisture. The second coat is important in ensuring that the wall remains dry and protected against moisture in the future.
Step 5: Preparing and applying the best polymer mortar
After the second coat of liquid rubber has dried, it is time to prepare the best polymer mortar for the wall. The polymer mortar is comprised mainly of liquid rubber and water, in a 1:6 ratio (1 part liquid rubber to 6 parts water).
The polymer mortar mix should be applied smoothly across the surface, attempting to fill in any defects, gaps, or cracks in the brickwork. After the polymer mortar has been applied properly, that wall will now be sealed and repaired adequately, while also adding adhesion properties.
Step 6: Curing the wall
After the polymer mortar has been applied, it is important to leave the wall to cure for 5-7 days. During this time, the polymer mortar will set and harden, creating a permanent repair.
Curing is vital for the performance of the wall as well as for the longevity of the repair and the moisture-proofing of the wall.
Step 7: Applying Polymer Modified Wall Putty Powder
As a final step, use a coat of polymer-modified wall putty powder. The putty will level any imperfections and leave you with a smooth, perfect finish.
It will also create another level of protection against moist conditions, which will provide a pristine, uniform finish and a durable coat for your walls.
