Is your home plagued by damp walls, mold, or peeling paint? Don't fret! Waterproofing your interior walls is easier than you think. Whether you live in a humid climate or have experienced consistent water damage in your bathroom or kitchen, taking the right precautions can help you protect your walls and prevent costly repairs.

Finding the Source of Moisture

Before you dive into waterproofing, it's essential to identify the root cause of the issue. This is particularly important when dealing with plumbing leaks or cracks in exterior masonry. Simply waterproofing your walls won't solve the underlying problem. Thoroughly inspect your home, paying close attention to bathroom and kitchen areas, window sills, door jams, gutters, and drainage systems. Repair any cracks or leaks you discover.

Invest in Drainage Systems

If a damp basement is your main concern, consider investing in a sump pump. These below-ground pumps help divert water away from your basement walls and foundation. For those without basements, exterior gutters can also prevent water-related issues on interior walls.

Fixing Cracks

Cracks in your drywall can be easily repaired using joint tape or drywall putty. Apply the chosen product as directed, then sand the area and seal it with a drywall sealer. When it comes to cracks in your basement walls, opt for a concrete sealer or liquid rubber to prevent further seepage.

Consider Replacing Materials

Instead of simply sealing and applying waterproof paint to your bathroom or kitchen backsplash, why not consider replacing the materials altogether? There are various types of waterproof tiles available that can add both functionality and style to your space. Remember, it's important to repair any existing damage before installing new materials.

Opt for Water-Resistant Drywall

While no drywall is entirely waterproof, certain types are better suited for damp environments. Traditional white drywall can be replaced with blue, green, or purple varieties that offer improved moisture resistance and help combat mold and mildew growth.

Seal Your Walls

If your walls are already painted, you'll need to remove the paint before applying a sealant. A good sealant will form a protective barrier over the drywall, providing an excellent base for painting. If you're working in a basement, use a deep-penetrating concrete sealer to fill in the porous concrete and prevent moisture absorption.

Explore Paint Options

Finish your waterproofing project with a waterproof primer and paint. A waterproof primer, when used in combination with a drywall sealer, significantly enhances the waterproofing qualities. Look for emulsion paints, which are water-based and offer a wide range of color options. Brands like Watertite specialize in waterproof paints, providing additional protection against water damage.

Things to Consider

It's essential to note that most waterproofing should ideally be done during the construction phase of your home. If you're waterproofing your interior walls after a remodel or repair, focus on the areas that need it most. Understanding the difference between waterproof and water-resistant products is crucial. While both help prevent moisture damage, waterproof sealers or masonry sealers are the most effective options.

By following these steps and taking necessary precautions, you can effectively waterproof your interior walls. Say goodbye to dampness, mold, and peeling paint, and enjoy a dry and comfortable living space.
