Waterproofing a Basement Floor Waterproofing a Basement Floor
Waterproofing a basement floor is a necessary step for many homes so that mold will not eventually start to grow. The process of waterproofing is not complicated, but it will take a little bit of common sense and some work. Here are the basics of how to waterproof a basement floor effectively.
Step 1 - Fix Cracks
The first thing that you have to do in order to waterproof your basement floor is fix any cracks that you might have. If you have cracks in the floor, water can get in the basement through them. If you have a very thin crack that is less than 1/8" you could potentially fill it with a caulk that is designed to fill cracks in concrete. If the crack is larger than that, you will need to patch it with a patching compound.
For this process, you need to clean out the crack. Use a vacuum to remove any dirt, dust, or broken pieces of concrete in the crack. Once you have cleaned out the crack, you can apply a bonding adhesive to it with a brush. This will help the new patching compound stick to the existing concrete.
Step 2 - Apply the Patching Compound
Once you have applied the bonding adhesive to the crack, you can start filling it with patching compound. For this part of the process, you should use a trowel to apply the patching compound. Make sure that the area is completely level once you are done applying it to the surface.
Step 3 - Primer
Let the patching compound dry completely for a few days. Once it is dry, you can start applying a primer to the surface of the concrete. Make sure that you get a primer that is designed to go on concrete basement floors. They make several products that are specifically designed for this application. Use a paintbrush or a paint roller to apply the primer to the floor. Then allow the primer to dry for a few hours before moving on.
Step 4 - First Coat
After the primer is dry, you can start applying a coat of paint. Typically, people will use an epoxy paint that has waterproofing capabilities. You can apply the paint with a paint roller or paintbrush. In most cases, using a paint roller will be the easiest because you will be able to cover a lot of ground faster than you would with a paint brush. After applying the first coat, allow the paint to dry before continuing.
Step 5 - Additional Coats
Most experts would recommend putting a second coat on your basement floor. In some cases, you may also want to put a third coat of waterproofing paint on the concrete floor. Three coats will improve the odds of keeping out the moisture and avoiding any moisture problems in your basement. Just make sure that each coat dries thoroughly before putting on another coat. Once all of them are dry, you can begin using the floor.
