Full Product Manual

Q: Can I use this on drinking water, rain barrels, fish tanks, etc.…?
A: Flex Paste has not been tested for safe use on potable water sources or around plants and animals.
Q: How do I apply Flex Paste?
A: 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)
Q: Can I smooth or tool it once it has been applied?
A: 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.
Q: How do I preserve Flex Paste?
A: 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.
Q: I lost my protective foil. What should I do?
A: 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.
Q: How long should I wait to apply a second layer of Flex Paste?
A: Allow 24 hours to cure before applying additional coats if needed.
Q: How long does it take for the product to fully cure?
A: 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.
Q: Once fully cured, does Flex Paste remain flexible?
A: YES, Flex Paste dries into a strong, flexible rubber that expands and contracts with the surfaces to
which it’s adhered.
Q: Will Flex Paste shrink?
A: NO, Flex Paste will not shrink, crack or peel.
