The formula self-levels to span small gaps and cracks, forming a watertight barrier as it cures. It’s paintable after drying and offers resistance to temperature and UV exposure, aiming for lasting repairs on outdoor projects. This product is not designed for continuous submersion or below-waterline use.

Real-World Uses and Surface Compatibility

Designed for exterior applications, it adheres to metal, concrete, wood, aluminum, brick, tile, fabric, rubber, glass, and more. Potential outdoor projects include repairing roofs, gutters, skylights, flashing, chimneys, window seals, RV roofs, and DIY exterior fixes. Note that some plastics and rubbers may vary in performance, and the product is not suitable for below-waterline scenarios.

How to Apply and Cure

• Clean the surface to remove dirt, dust, grease, and oil; ensure complete dryness before application
• Stir contents for 30 seconds until fully mixed to activate the rubberized coating
• Apply using brush, roll, trowel, dip, or pour; ensure complete coverage of cracks and gaps
• Apply multiple coats as needed; allow curing between coats and before exposure to water

Full cure typically occurs within 24–48 hours under suitable conditions. After curing, the coating accepts latex or oil-based paints; if using oil-based paints, a primer is recommended before painting. For best results, test a small area with light water exposure and recoat if necessary.

Practical Tips

• Prepare for exterior use only and store with a tight seal to preserve remaining product
• Clean applicators with a dry cloth; mineral spirits can be used for brushes and rollers
• Monitor temperature guidelines and keep application within the 50F to 120F range for proper curing
