How Can You Use Flex Seal to Waterproof a Basement?
For waterproofing basements, Flex Seal is one of the most widely recognized products. Using Flex Seal, you can ensure that no water will enter the basement. Upon application, the product coats, seals, and protects foundation cracks through which water can enter.
If you have a basement prone to flooding, here are the steps you need to take:
Step 01. Gather All Materials
When working with Flex Seal to insulate a basement, you will need:
- Wire brush
- Vacuum cleaner
- Painter’s tape
- Drop Cloth/Plastic Sheeting
- Flex Shot
- Flex Seal Liquid MAX
- Paint Brush
- Plastic Paint Container
- Paint Roller
- Paint Tray
Step 02. Prepare the Applying Basement Area
Before applying Flex Seal to your basement, you must prepare the area properly. First, clear out any debris or obstacles that might get in the way of a smooth application. Next, use a wire brush to remove any loose paint or flakes.
Now power wash to clean the surface of the basement, paying special attention to any cracks or gaps. You can also use a vacuum cleaner with a hose attachment to remove any cobwebs or dust.
Next, cover the basement floor with drop cloth or plastic sheeting and secure them with painter’s tape. Once the area is clean and dry, you are ready to apply Flex Shot.
Step 03. Apply the Flex Shot
Basement cracks are notorious for being damp and musty, but there are ways to waterproof them to make them more resistant to flooding. One way to do this is by using Flex Shot with a caulking gun that applies a thick bead of sealant to cracks and holes.
Flex Seal spray shot forms a waterproof barrier that stops water from seeping in and causing damage. It is also great for sealing around windows and doors. To apply Flex Shot, point the nozzle at the area you want to seal and squeeze the trigger.
The sealant will come out in a thick bead that will adhere to the surface and create a tight seal into the cracks. Once the sealant has dried, it will be clear and will not affect the appearance of your basement.
Step 04. Apply the Flex Seal liquid
Unlike traditional sealants, Flex Seal can be applied directly to wet surfaces and will not wash away with rain or snow. It is also resistant to mold, making it ideal for use in damp basements. To apply Flex Seal, transfer some liquid into a plastic paint container or tray.
Using a paint brush or roller, apply the Flex Seal to the areas you want to waterproof. For best results, apply a thick coat of sealant. For the corners, it is best to use a paintbrush to reach the cracks better. You can also use Flex Seal Liquid MAX for larger jobs.
Because Flex Seal liquid self-levels, it may appear rough when applied to a surface, yet, the surface will start to smooth out as it dries. Ensure that you apply the product gently, pushing it into all cracks and divots rather than rolling it to ensure a level and sealed surface.
Step 05. Let the Seal Dry
Once you have applied the Flex Seal to all the cracks and gaps in your basement, let it dry for at least 24 hours. During this time, open all the windows and doors to ensure proper ventilation. If there is moisture in the air, use a dehumidifier or fan to help speed up the drying process.
After 24 hours, Flex Seal will be dry to the touch and will have formed a waterproof barrier. You can now use your basement wall without worrying about flooding or leaks.
Flex Seal is an excellent product for waterproofing basements and protecting them from flooding. Following the steps above, you can ensure that your basement is adequately sealed and protected from the elements.
