Description
Product Overview
Flex Paste is a clear, waterproof, paintable putty designed to create a durable, flexible, rubberized seal that protects against air, water, and moisture intrusion. Engineered by Swift Response, this sealant combines a high‑performance polymer matrix with advanced UV‑resistant additives, delivering long‑lasting protection in both indoor and outdoor environments. The product is supplied in a convenient half‑quart container, making it easy to handle for both professional contractors and DIY enthusiasts. Its thick, tacky consistency allows it to cling to vertical and horizontal surfaces, filling gaps, cracks, and holes up to several centimeters wide without sagging or shrinking. Once cured, the material becomes a flexible, watertight barrier that can be sanded, primed, and painted to match any surrounding finish, making it ideal for a wide range of repair and maintenance projects.

Usage
Flex Paste excels in a variety of applications where traditional caulks and fillers fall short. It can be applied to walls, drywall, concrete, masonry, EPDM roofing membranes, and even the fiberglass surfaces of recreational vehicles. Because the formula cures to a rubberized state, it remains flexible under temperature fluctuations, preventing cracks caused by expansion and contraction. The sealant can be used underwater, allowing repairs on submerged surfaces such as boat hulls, pool liners, and irrigation systems without the need for drying time before application. Its UV‑resistant properties ensure that exposure to sunlight will not degrade the seal, making it suitable for exterior repairs on roofs, siding, and balcony railings. The product also adheres well to metal, providing a protective layer that helps prevent rust and corrosion when painted over.

FAQ
Can Flex Paste be applied in temperatures below freezing?
Yes, Flex Paste can be applied in cold conditions down to 32°F (0°C). The formula remains flexible enough to adhere and cure, though cure time may be slightly longer in colder environments.
Is the sealant safe for use on food preparation surfaces?
Flex Paste is a non‑toxic, solvent‑free product once cured. It is safe for use on surfaces that may come into contact with food, provided the area is thoroughly cleaned and painted with a food‑grade coating before exposure to food.
How long does it take for Flex Paste to fully cure?
Initial skin formation occurs within 30 minutes, and the sealant reaches full cure strength in 24 hours under normal indoor conditions. Full cure may take longer in high humidity or low temperature environments.
Can I sand the cured Flex Paste before painting?
Yes, after the sealant has fully cured, it can be sanded to achieve a smooth surface. This prepares the area for optimal paint adhesion and a flawless finish.
What is the recommended storage condition for unused Flex Paste?
Store the unopened container in a cool, dry place away from direct sunlight. Keep the lid tightly sealed to prevent the product from drying out. Unused product can be stored for up to 12 months under these conditions.
