Clean damaged area with Cotol-240™ Cure Accelerator/Precleaner or solvent (paint thinner, nail polish remover or similar). Trim loose threads. Non-fabric surfaces should be roughened with sandpaper, then cleaned. Apply Aquaseal® to surfaces directly from tube or with knife or flat stick. Keep repair level overnight. Avoid contact with other surfaces. Most repairs reach full strength overnight (10–14 hours). Allow longer for thickest repairs. For fastest cure (2 hours or less), mix in Cotol-240.
