How to Waterproof Your Garage

A garage is a part of your home that many tend to overlook when they think of home improvement projects. While there are seemingly endless DIY projects for bathrooms, bedrooms, backyards, and decks, projects for your garage are often overlooked. One project many people forget about is waterproofing their garage. While your basement is the first and most important waterproofing project in your home, you shouldn’t forget that your garage could also benefit from a good waterproofing job.

Your garage not only protects your cars, it’s quite often also storage for other valuables and household goods. Heavy rains can also threaten your garage and while your car can survive low-lying water, some of the other objects you store in your garage cannot. For this reason, here’s how to waterproof a garage floor.


What You’ll Need: SANI-TRED PermaFlex, LRB (Liquid Rubber Base), TAV (Thickening Activator), paint roller, trowel


Step 1 Prepare the space

Remove everything from the garage until you’re left with the bare structure. Prepare concrete by degreasing, power washing and acid etching concrete.


Step 2 Apply first coat of SANI-TRED PermaFlex

After mixing PermaFlex with the activator, apply PermaFlex to the floors and walls of your garage. Allow to dry for 1-2 hours at 70 degrees Fahrenheit.


Step 3 Inspect the area

Look over the walls and floor area for cracks or other damage.


Step 4 Fix any damage

Mix LRB with the TAV and apply it to any cracks you find in the wall and floors.


Step 5 Finish waterproofing

Apply top coat of PermaFlex to the area, let dry for 1-2 hours at 70 degrees Fahrenheit.

Step 6 Enjoy your new waterproof garage

Following these steps, your garage will be waterproof and will protect the valuables you store there. A waterproof garage can safeguard your belongings and should be considered for your next DIY project.
