Waterproofing your basement floor is necessary. This process isn’t complicated, but will take time and effort to complete. The first thing you must do to waterproof your basement floor is to inspect the floor for any cracking. If you have cracks in the floor, water will seep up through them. For small cracks, use caulk to fill it with concrete. For the larger cracks, you’ll need to patch it with a patching compound. After the patching compound has taken the time to dry, you can start applying a primer to the surface of the concrete. Make sure to buy a primer that is designed specifically for basement floors. Use a paintbrush or roller to apply the primer to the floor. Then allow this primer to dry for a few hours before moving on. After the primer completely dries, you can start applying waterproofing paint. You should look for an epoxy paint that is specifically designed to waterproof concrete. Again, use a paintbrush or roller to apply this paint, and then allow the first coat to dry before applying more. Apply up to three coats to maximize the effectiveness of the paint. Just make sure each coat dries thoroughly before the next. Once all of them dry, you can begin using your newly waterproofed basement floor.
