Why Do You Need to Waterproof Your Garage Walls?
Waterproofing garage walls can help prevent water from entering and damaging the structure of your home.
It also helps prevent mold growth, which can harm your health. Additionally, it prevents rust and corrosion on the walls, helping you keep the appearance of your garage in good condition for longer.
If your garage wall has been damaged from years of exposure to moisture, it might be a good idea to waterproof the area before you attempt any repairs. As the damage may be more severe than you first anticipated.
What Materials Do You Need?
To waterproof your garage wall, you’ll need:
- A paint roller and tray
- An airless sprayer (optional)
- Exterior-grade waterproofing paint or sealant
- Painter’s tape (optional)
How to Waterproof a Garage Wall: 7 Steps to Follow
Step 1. Cleaning the walls
Start by cleaning the wall with a pressure washer or power sprayer and let it dry completely. This will remove any dirt, grime, and debris that could prevent the paint from adhering properly. If your walls are severely damaged, you may need to repair them before painting.
Step 2. Fill the crack & holes
Fill in any cracks or holes using a putty knife with a patching compound. Allow the filler to dry before applying primer and paint. You can also use a caulking gun to fill in any gaps between the wall and the floor.
Step 3. Apply primer
Apply a coat of exterior-grade primer using either a paint roller or an airless sprayer. This will help the paint adhere to the wall better and prevent moisture from entering the walls. If you’re unsure which primer to use, you can go for Drylok, an all-purpose waterproofing primer.
Step 4. Apply the waterproofing paint/sealant
Once the primer is dry, you can begin applying your choice’s exterior-grade paint or sealant. When using a roller, use even strokes and cover each area completely. You may need two coats of paint or sealant for complete coverage.
Step 5. Sealing the bottom of the wall
To protect your garage from water seepage, use a paintbrush or caulk gun to seal the bottom of the wall.
This will create a barrier between the ground and your walls, preventing moisture from getting in. You can add extra protection by applying a layer of plastic sheeting underneath the wall.
Step 6. Drying the wall
Once you’ve finished waterproofing the walls, it’s important to let them dry completely before using your garage. This could take up to several days, depending on the temperature and humidity in the area. Do not use any heat sources near the wall during this time, as it could cause damage.
Step 7. Finishing touches
Once the wall has dried, you can finish the project by adding decorative trim or accents. This could include an outdoor light fixture, weather stripping, or a skirting panel.
You can also use painter’s tape to make a clean line between the waterproof section and the rest of the wall.
Once you’ve completed these steps, your garage walls are ready for use. Always make sure to check the walls regularly for signs of damage or wear and tear, and reapply waterproofing as needed.
With proper care, your garage walls should stay protected from water damage for many years.
Make Your Garage Walls Sustain Last Longer with These Tips:
1. Inspect the walls for damage regularly.
2. Apply a fresh coat of waterproofing paint or sealant to protect your walls against water seepage.
3. Fix any cracks or holes in the wall immediately.
4. Keep the area around your garage dry and free from standing water.
5. Add extra protection by using a vapor barrier to prevent moisture from getting through.
6. Use insulated panels on the exterior of your garage walls to keep the temperature regulated inside.
7. Make sure that air can circulate within the garage by opening windows and doors often.
8. Clean off dirt, dust, and cobwebs with a hose or cloth to keep the walls looking fresh.
Tanking Your Leaking Garage Wall:
If you have a leaking garage wall, the first step is to move any furniture, fixtures or things out of the way. Check for signs of water damage like discolored patches on the walls, pools of standing water, or mold and mildew growth.
The next step is to prep the wall by cleaning it thoroughly with a hose, brush, or pressure washer. This will help remove dirt and debris that could interfere with the waterproofing process.
Next, you’ll want to use a concrete or masonry patching compound to repair any cracks in the wall that could allow the water to seep through.
After you have prepped and patched the walls:
- Put a waterproof sealant on.
- Get a good sealant that is made for garage walls.
- Read the instructions on the package carefully.
- If it rains a lot where you live, add an extra layer of protection with a waterproofing membrane.
Finally, apply any finishes you want (like paint or sealant) and let the wall dry completely before putting the furniture back in place.
With these simple steps, you can easily waterproof your leaking garage wall.

It’s important to inspect your garage walls regularly to ensure they stay in good condition. Apply a fresh coat of waterproofing sealant or paint as needed.
Additionally, fix any cracks or holes in the wall and keep the area around your garage dry and free from water.
