YES… to understand the best way to apply, use and preserve your Flex Paste, it’s important to READ ALL DIRECTIONS before use.
Flex Paste is a super thick rubberized paste that clings to the surface and instantly fills large gaps, cracks and holes. Once dry, Flex Paste turns into a strong, flexible, watertight, rubberized coating that seals out air, water and moisture on a variety of surfaces and objects.
Flex Paste is offered in black or white and available in the following sizes:
- 9oz cartridge (caulking gun required)
- 1 lb. jar
- 3 lb. tub
- 6 lb. tub
- 12 lb. MAX tub
You can use Flex Paste on a wide variety of surfaces such as wood, glass, tile, concrete, aluminum, metal, brick, stucco, masonry, copper, fabric, fiberglass, ceramic, porcelain, natural stones, roofing, PVC, EIFS, EPDM, CSPE, Hypalon polyurethanes and so much more.
Flex Paste adheres to a variety of surfaces. However, it may not adhere to certain plasticized or rubber surfaces. We recommend testing in a small inconspicuous area before using.
One pound of Flex Paste provides about 10 linear ft at 2 inches wide with a layer thickness of approx. 1/16th inch.
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. For best results apply a generous amount to the surface using firm pressure. This will help push the water out and allow better contact to the surface during application. Etching the surface may help with adhesion on both wet and dry surfaces.
Flex Paste is perfect for DIY, Handyman projects, arts & crafts, hobbies and so much more! Use it to repair your roof, winterize your home, plumbing repairs, to seal cracks, automotive or marine repairs, pool and spa repairs, and so much more.
YES, it is an excellent waterproof sealant. Flex Paste can be used on windows, doors, vents, thresholds and so much more. It will create a watertight barrier that seals out air and moisture. Use Flex Paste to help prevent flood damage. It can even be used to fill large voids to help keep insects and rodents out of your home.
Flex Paste has not been tested for safe use on potable water sources or around plants and animals.
Use a putty knife, trowel or similar tools to remove a smooth even layer of material from the top of the tub. Scooping deeply into the tub may cause air pockets which can dry the Flex Paste. Apply a generous amount using a smooth sweeping motion. (see label instruction)
Depending on temperature, humidity or the thickness of the layer, Flex Paste can be tooled within 15-30 minutes of the initial application. It will dry to the touch in approximately 2 hours and fully cure in 24 to 48 hours. Flex Paste gets stronger over time.
Flex Paste begins to cure once exposed to air, moisture and humidity. To ensure fresh, usable product, there’s a protective foil on the surface of the Flex Paste. This protective foil helps keep air, moisture and humidity out of the tub. DO NOT DISCARD PROTECTIVE FOIL OR SILICA GEL PACKET!
1. After each use, always replace the protective foil and the silica gel packet.
2. Start by pressing the foil on the center of the surface of the product and continue pressing outwards so the foil remains in constant contact with the Flex Paste.
3. Make sure no air pockets have formed between the foil and Flex Paste.
4. Once you reach the edge of the tub, press the foil around the inside perimeter, keeping the excess foil facing up.
5. Replace silica gel packet and secure the lid.
Before use, always remove any dry material or skin that may have formed on the surface. Do not mix dry and fresh Flex Paste together in the tub.
Cut a piece of heavy-duty aluminum foil larger than the opening of the Flex Paste container by a ½ inch all the way around. Use it in place of the protective foil after each use.
Allow 24 hours to cure before applying additional coats if needed.
Depending on the thickness of the layer the product needs 24 – 48 hours to fully cure. Temperature and humidity levels will also impact the curing process. Humid environments will cure the product faster than dry environments. If the treated area is still wet or soft, it will need more time to cure.

NO, Flex Paste will not shrink, crack or peel.
YES, once fully cured, it can be painted any color.
Unlike spackle or joint compound, Flex Paste dries to a waterproof, flexible rubber. Therefore, sanding may not be the best option once Flex Paste has cured. Instead of sanding we recommend using a putty knife, trowel or similar tool to smooth over the surface of the Flex Paste to your desired finish. You can even add designs and patterns to Flex Paste to create your own unique artistic textures.

Application tools may also be cleaned with a dry cloth and with acetone or mineral spirits as needed. Once fully cured, Flex Paste can be removed with a sharp tool like a chisel or a putty knife. However, it may not be possible to remove it without damaging the surface.

With proper application, care and maintenance, Flex Paste will last for years.
There are a variety of factors that can impact the maximum pressure Flex Paste can withstand. Depending on the thickness of the layer applied, the surface type it’s being applied to, the size of the crack or hole to be sealed, Flex Paste will withstand a wide range of hydrostatic pressure. Always wait until the Flex Paste is fully cured before testing.
To increase the life of the product we recommend always replacing the foil and silica packet after each use and closing the lid tightly. Whenever possible, store your Flex Paste in cool dry place.
