How to Waterproof a Surface with Sealant Paint

Whether you need to waterproof your basement walls, the outside of your home, or your bathroom, you can do so with waterproof sealant paint. The paint comes in different levels of waterproofing ability, so you can buy a more heavy duty kind for places like inside your shower where there is regular exposure to moisture. It is made from oil or latex and is often clear, but you can also buy it in shades like white or gray. It’s easy to use and you can waterproof any surface in your home by yourself.

Choosing a Paint

The first step is to choose a paint. You can do this by deciding where you want to paint and then finding a sealant that is created for the purpose. There are sealant paints for the roof, your shower, the concrete in your basement, and more. Rubber roof paint might be more heavy duty than what you would use for floor coatings in your living room.

Start with a Smooth Surface

Like with any paint you want to start with a clean, smooth surface. Waterproof products will be more effective when they are evenly distributed over a surface without a lot of bumps or cracks. Depending on what surface you are waterproofing you might need to do some sanding, seal cracks and holes, or just do a general washing of the surface to get rid of unwanted dirt and grime.

Protect Other Surfaces and Objects

If you’re painting indoors then it is wise to cover your floor and move away objects that you don’t want to get sealant on. You can lay down a tarp to protect your carpet and use masking tape to protect smaller areas.

Begin with Product Application

To apply the waterproof sealant paint you can use a paint roller for quick and effective coverage. It is often a good idea to add a second layer just to be sure that everything is covered, because paint rollers don’t always apply completely even coats. You can perform a waterproof test after the sealant has dried to make sure that the product is working appropriately.

Waterproofing surfaces in your home is a relatively simple process that is very similar to normal painting. You can often finish it in a day if you put the time in and have well protected walls and floors in no time.
