Cure times can vary depending on bead size, temperature, and humidity. Generally, it will be touch-dry within a few hours and fully cure within 24-48 hours. Refer to the product packaging for specific details.
Store unused tubes upright in a cool, dry place, ensuring the nozzle is either sealed or a small amount of sealant remains in the nozzle tip to prevent air ingress and curing. For best results, use within the recommended shelf life.

Each tube in the 3-pack is 290ml.
Ensure the nozzle is cut appropriately and the tube is punctured correctly. Check if the sealant has started to cure inside the nozzle or tube. Try using a high-quality sealant gun with sufficient leverage.
Verify that the surfaces were thoroughly cleaned, dried, and free from any contaminants like dust, oil, or old sealant. Ensure proper surface preparation, including light abrasion if necessary for non-porous materials.
This could be due to low temperatures, high humidity, or applying too thick a bead. Ensure application is within the recommended temperature range and allow adequate curing time in appropriate conditions. Avoid disturbing the seal during the curing process.
Practice applying on a scrap surface. Use masking tape to create clean edges before application and remove it immediately after the bead is laid and tooled. Ensure consistent pressure on the sealant gun.
