Flex Seal Liquid is a helpful resource for fixing driveway damage. The product can be easily poured into cracks and crevices for repair. It's important to note that we do not recommend sealing large areas that receive a lot of foot traffic because the liquid can become slippery when wet.
A: Yes many people have had great success in filling cracks in their driveway. For large cracks you can pour the liquid in to make sure it fills in completely and then brush or roll over to smooth it out.
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.
Q: How much pressure will it withstand? A: Flex Seal will withstand normal hydrostatic water pressure such as rainwater, but it is not made to withstand extreme pressure. Q: Can I apply it on a wet surface? A: Flex Seal can be applied on a wet surface or moist environment in an emergency.

A properly applied application of Flex Seal will last 3+ years in normal conditions. Please note that Flex Seal doesn't withstand high heat or pressure.
According to HomeAdvisor, a driveway repair professional will charge as little as $300 to fix minor concrete driveway cracks, but most homeowners can do the job on their own with a rubber or synthetic crack filler. This costs about $0.10 to $0.15 per linear foot—but watch out if cracks are larger than 1/8 of an inch.
The sooner you take action to repair cracks in your driveway, the better. Cracks left unattended for long periods of time can expand when water finds its way into them and freezes, potentially widening the cracks.
Plus, it won't sag or drip in the summer heat, and it won't crack or peel in the winter cold. It even prevents corrosion. There are many practical and creative ways to use Flex Seal.
If you need to repair a concrete crack that's a minimum of 1/4-inch wide up to a maximum of 1 1/2-inches wide and 1/2-inch deep, then our top recommendation is Sikaflex Pro Self-Leveling Sealant. This polyurethane sealant dries to the touch in just one or two hours but can take three to five days to fully cure.
Generally speaking, you can use concrete sealants to repair or protect concrete surfaces. If you have a repair project at hand, you will want to use a flexible filling material like Loctite PL Concrete Self-Leveling Polyurethane Sealant to repair driveways, garage floors, concrete floors and decks, and sidewalks.
Brick: For sealing gaps in brick, a silicone caulk such as DOWSIL 758 Silicone Weather Barrier Sealant is a great choice. It's waterproof and can withstand extreme temperatures, making it ideal for use around windows, doors, and other penetrations.
While you may see small driveway cracks as nothing important, they can be the first sign that you may have foundation issues.
In hot temperatures, the pavement expands and closes the cracks. This is why spring and fall are considered the optimal time for crack repair. In the cold temperatures of winter, pavement contracts and cracks open to their widest. In the hot summer season, the pavement expands and closes the cracks.
In fact, all cracks need to be repaired before sealcoating, not just the large and obvious ones. Sealing an unfilled crack simply means that the crack will continue to grow underneath the applied sealant. So Seal King does the job right for each and every job.
Small cracks (less than 1/4 inch in width and depth) can be repaired using concrete or asphalt filler. Medium cracks (1/4 to 1/2 inch) should be repaired with patching compound or pre-mixed mortar. Large cracks (more than 1/2 inch) need to be repaired with pre-mixed concrete or asphalt (the cold patch variety).
A: YES, Flex Paste can be applied on dry or wet surfaces and even underwater. It won't dissolve or wash away and even dries underwater.
You can easily remove Flex Seal from any wood surface with patience and elbow grease. I've read of others having success with spraying WD-40 on the Flex Seal overspray. You can then take a damp cloth and wipe off the Flex Seal.
Yes, Flex Glue is fully waterproof, and there are countless uses for applying the instant grab and hold adhesive when it comes to all of your waterproof glue needs. Since Flex Glue can be applied underwater and can even fully cure underwater, it's no wonder our product is considered the finest waterproof glue around.
A: Flex Seal Liquid can be poured as thick as you need it, but the dry time will increase with thickness. We timed dry time for something that was a half inch thick and it took about 8-9 days to dry. Temperature and humidity play a factor as well.
Flex-Seal Utility Sealant will not bond properly to uncured cement. If coating PVC, fiberglass or epoxy, the surface must be clean and abraded with 40 grit sand paper, then coated with “NHNS” to ensure proper adhesion prior to the application of the primer.
