We do not recommend using Flex Seal on foam. Some foams may react poorly with Flex Seal, and may warp or dissolve. We also do not recommend using it in situations where it is subjected to high heat or pressure (such as engine radiators) or gas tanks. We do not recommend the use of Flex Seal spray on vinyl.
A: Yes you can use Flex Seal on concrete.
Depending on the environment, coats added, and maintenance, many people have found Flex Seal will last for years without cracking, peeling, or losing any of its strength or sealing properties.
Use a wire brush or pressure washer to clean the surface thoroughly. Repair any cracks or gaps in the concrete with an appropriate filler. Choose the right waterproofing material There are several types of waterproofing materials available, including liquid coatings, membranes, and sealants.
Epoxy is a robust sealer known for its durability and resistance to moisture, making it an excellent choice for basements that are used frequently or are prone to dampness. This type of sealer creates a thick, protective layer over the concrete, which helps prevent water penetration and resists stains and chemicals.
Drylok is an indoor waterproofing paint, and while that has been mentioned several times, it is a crucial detail. Waterproofing your basement from the inside may be cheap, but it is by far the least effective way of waterproofing your basement, and this is because it never stops the source of the water.
Sealing basement walls helps protect your home from water damage, ensuring a dry, healthy living space. Whether you're dealing with minor dampness or recurring leaks, understanding how to waterproof your basement can save you time, money, and headaches in the long run.
Flex Seal Liquid is optimal for sealing, repairing, and weatherizing concrete. It works by sealing out air, water, and moisture and is mildew, chemical, and UV resistant. You can either brush, roll, dip or pour the liquid directly onto the concrete surface.
Once dry, Flex Seal's watertight, rubberized coating can withstand water, heavy rains, snow, and more. Flex Seal can be applied to a wet surface or moist environment in the event of an emergency. However, it will always adhere better to a clean, dry surface.
Flex Seal Liquid is not compatible with Drylock.
For minor leaks and moisture, you can use hydraulic cement, silicate concrete sealant, and silicone caulk to fill cracks and gaps. You can apply these products yourself, followed by waterproof paint. Larger problems may call for exterior drainage improvements or professional foundation repairs.
If the Flex Seal is still wet, it can be removed with a dry cloth or paper towel. If the Flex Seal is cured/dry, it can be removed with acetone, denatured alcohol, or mineral spirits.
A: Yes! Flex Caulk is 100% waterproof and can be applied to wet or dry surfaces. It will even cure underwater.
Superior Waterproofing Performance: Crystalline Waterproofing offers a higher level of waterproofing performance compared to Drylok Extreme.

Which is the cheapest basement waterproof? The cheapest basement waterproofing method is typically applying a waterproof paint coating, which can cost as little as a few dollars per square foot for materials if doing it yourself. Caulking cracks and opting for interior solutions is cheaper than exterior excavation.
If the water is seeping through the concrete walls themselves, it may be necessary to waterproof the exterior of the walls. This may involve applying a waterproof coating or membrane to the walls or installing a drainage system to direct water away from the building.
DRYLOK® Masonry Waterproofer is not recommended for use on anything other than bare masonry and concrete surfaces. It can be applied to porous terra cotta, concrete, stucco, and cement.
