4 Tips for Using Waterproof Paint in Your Basement 4 Tips for Using Waterproof Paint in Your Basement

Never neglect to use waterproof paint to protect your basement against moisture. The basement is cooler when compared to the rest of the home, leading to dampness. If there are any imperfections in the foundation wall, then water will find a way to get into the basement.

Waterproof paint will not protect from a flood of water, but it will lessen the dampness, moisture, and mold. The following information will share several tips on how you can use waterproof paint to properly protect your basement.

Start With a Dry Surface

It may seem silly to want to have a dry surface in order to apply waterproof paint. In order for the paint to adhere to the surface, the wall must be dry. If it is not dry, moisture will simply be trapped in the material.Use a wet and dry vacuum to remove any water that has accumulated in the basement.

Dampness is also a factor. To combat that problem, use one or more dehumidifiers. How many you use will depend on the size of the basement. The dehumidifiers will leach the moisture from the air, which will dry the basement.

Basement Repair

Applying waterproof paint to the basement walls is not a substitute for basement repair. Painting over bad areas with the waterproof paint will just be a waste of time. In order to get the best possible seal from the waterproof paint, you must do some grunt work.

Use a wire brush to remove any loose mortar on the walls. Fill any holes with fresh mortar. The easiest method is to mix small batches of mortar and fill a pastry bag with it. You can then easily fill these areas with the mortar. Wet your finger and smooth out the excess. Wait for the mortar to fully cure before applying waterproof paint to the basement walls.

Don't Avoid the Edges

One mistake that homeowners make is applying waterproof paint to a wall then stopping. Water will find a way into the basement from every hole and space imaginable. Closely examine the basement, paying attention to the seams where the walls and ceiling meet.

You will most likely notice very small spaces between them, which form naturally as the home settles. It is important to not only use mortar to seal these small gaps, but to also apply waterproof paint over them.

It's in the Details

Concrete is a very porous surface that absorbs moisture like a sponge. One coat of waterproof paint is not sufficient to properly seal the basement wall. Use at least 2 coats of paint to ensure proper protection.

Once the last layer of paint has dried, it is time to play detective. Look very closely at the wall for any voids in the waterproof paint. When you find one, paint over it.
