FAQs

Can I paint over this sealer?

Yes, once the sealer is fully cured, it can be overcoated with nitro-cellulose, acrylic, or compliant refinishing paint systems.

Does this product work on vertical surfaces?

Yes, its non-slumping characteristics make it ideal for both vertical and horizontal joints.

How long does it take to dry?

The sealant requires approximately 2 hours to dry at 20ºC.

What tools do I need for application?

You will need a standard caulking or sealant gun to apply this product.

How should I store the leftover sealant?

Store it in a cool, dry place and ensure a bead is left in the nozzle to cure and act as a plug for the rest of the tube.

Is this product water-resistant?

Yes, it is specifically designed to protect overlap seams against both water and dust penetration.

Troubleshooting

Sealant is difficult to squeeze from the cartridge.

Ensure the bottom seal of the cartridge has been completely punctured and removed, and verify that the nozzle tip is cut large enough for the product viscosity.

Sealant hardened inside the nozzle between uses.

Always leave a small amount of product protruding from the tip after use to act as a seal; if it still hardens, remove the nozzle and clear the obstruction with a stiff wire.

Pros and Cons

Pros

  • Resists slumping on vertical surfaces
  • Provides a durable, flexible seal
  • Compatible with a wide range of topcoats
  • Simple application using standard caulking guns

Cons

  • Requires a caulking gun not included in the pack
  • Two-hour dry time may delay immediate painting
  • Moisture-curing nature requires proper storage to prevent premature hardening

Setup, Compatibility & Care

To prepare the cartridge for use, first remove the plastic nozzle extension and push the internal nozzle seal inwards. Cut the nozzle tip to your desired bead width and screw it back onto the cartridge. Finally, punch and remove the bottom seal of the cartridge before inserting it into a standard caulking gun.

To ensure product longevity, avoid exposing the cartridge to excessive humidity during storage. If you do not use the entire contents of the tube, leave a small bead of material protruding from the nozzle tip. This protruding bit will cure, creating a natural plug that keeps the internal material fresh. Before your next project, simply pull this hardened plug out of the nozzle to clear the path for fresh sealant. Always store in a cool, dry environment.
