Bathrooms are one of the most moisture-heavy spaces in the home, which makes them prone to mold, leaks, and water damage if not properly waterproofed. The good news is you can handle a lot of the basic waterproofing tasks yourself without needing to call in a contractor.
What You Will Need
A bucket, a paint roller, waterproofing membrane or liquid sealant, painter’s tape, a brush for corners, and gloves.
Step One: Clean the Surfaces
Start with a clean surface. Remove dust, grime, or leftover adhesive from your bathroom walls and floors. A simple scrub with soap and water is often enough. Dry the area fully before moving on.
Step Two: Apply the Tape
Use painter’s tape to cover any areas you do not want coated with sealant, such as trims or edges. This makes your work neat and professional.
Step Three: Apply the First Layer of Waterproofing
With a roller or brush, apply the liquid waterproofing membrane to your floor and walls. Make sure you push it into the corners and edges where leaks often begin. Allow the first layer to dry completely.
Step Four: Apply a Second Layer
Once dry, add a second coat for extra protection. It may feel repetitive but the double layer is what keeps water from seeping in over time.
Conclusion
Waterproofing your bathroom might feel like an advanced project, but the steps are simple once you break them down. By taking a little time to protect your walls and floors, you can save yourself from expensive repairs later. A well-waterproofed bathroom is safer, healthier, and much easier to maintain.
