    Things to Consider When Painting Water Resistant Walls

    • Remove Water Covering

    First of all, if your wall is covered by water you must remove the water covering the wall, treating the wall behind it and then replacing it with a new one. Water resistant paint for internal walls like an acrylic would also work well against high humidity. If the wall has no water resistant paint on it and is only partially covered by water, you can apply a water based acrylic wall coating. For external walls, you can still use water based acrylics or even latex but make sure they are water resistant before applying them.

    • Apply Pain Primer

    Another thing you must do is to treat your home’s existing water based paint with a mold inhibitor and a good quality paint primer. You should make sure that the paint is completely dry before removing the mold inhibitors. Mold inhibitors prevent mold and mildew from growing and spreading on the surface of the wall. If the vapor barrier is missing or damaged, you should immediately replace it so that your basement vapor barrier does not continue to deteriorate and become ineffective. Any time you have a vapor barrier in your basement, you should also have a basement vapor barrier paint applied.

    • Clean the Outer Surface

    All exterior walls should be treated the same way as the interior ones. In order to get a good result, you should clean the outer surface of the wall using a bleach and mop water solution. If you have concrete or cement walls, you can mix some cement dust with water and create a paste that you can apply to the surface. This paste would prevent water from penetrating your paint and will give you a Matt finish.

    • Apply Wood Veneer

    Once you have cleaned the exterior part, you can then prepare the interior of the wall. Start by applying a wood veneer over the concrete. Then, add some more wood veneer as well as some gravel at the bottom part. Then, add concrete dust to fill the spaces between the wood veneer. Finally, apply another layer of wood veneer. Keep in mind that the vapor barrier paints are highly effective against moisture, but they are not able to stop stains.

    • Apply Water Vapor Barrier on Interior Walls

    Make sure you apply the first coat of water vapor barrier paint on a drywall surface. You can then apply the second coat after the first one has dried up completely. Just make sure that you use the right type of drywall. In most cases, it is best to use fiberboard, because this kind of drywall has a small gap at the top. This will trap any water that would get through the paint and prevent it from getting to the surface underneath.

    Most interior walls should now be ready for the third and final coat of water vapor barrier paint. Since you have used the first coat as a moisture barrier, it will be even easier to do the last one. Just make sure that your primer is thoroughly dried before you apply the water vapor barrier. You can also use an exterior sprayer to get any water droplets that may be left on the walls.

    • Apply Water Vapor Barrier on Exterior Walls

    Exterior vapor barriers are also quite effective for protecting the concrete surface of the exterior walls. These products have a high R-value, which means that they are able to significantly dampen the sound of an outside echo. In fact, many soundproofing products nowadays contain this R-value. Damp proofing products are ideal to use on garages, sheds and industrial buildings, where dampness is a common occurrence.


    Water vapor barriers are not only used on the wall itself. You can also find these products for trim, ceilings, doors and windows. These products will help prevent water penetration into the structure. This way, your home will stay dry even if there is a persistent water leak. So if you find your home is suffering from water leaks and dampness problems, apply one of these products around the perimeter of your house to help reduce moisture problems.
