## Description

Product description Stops leaks fast. Starts out as a thick liquid and dries to a super strong, flexible, watertight, rubberized coating. Seeps into cracks and holes. Blocks out air, water, and moisture for a superior seal, virtually anywhere. Prevents rust and corrosion. Extends the life of patio furniture, pool pumps, RV and shed roofs, and more. Stands up to extreme weather changes. Expands, contracts, flexes and stretches. Resists rain, snow, sun, and hail. Exceptional adhesion. Works on all types of surfaces, even challenging ones, like metal and glass. UV and chemical resistant. Use indoors and outdoors for basement waterproofing, foundation fixes, roof repairs, and more. DIRECTIONS Fully clean and dry the surface for best results. Etch the surface to help with adhesion if needed. For the best application, use a standard disposable paint roller or paint brush. Apply several even, thin coats and wait 24 - 48 hours for each layer to fully dry before adding the next. Always place the lid back on the container after each use. If drying occurs, remove any skin before using product.

### ⭐⭐⭐⭐ GREAT PRODUCT! It works!!
*by C***M on June 25, 2020*

My order to 3 weeks to arrive. Once it arrived I noticed that the 2 cans had multiple dents. I used this product to seal leaks in my studio ceiling. My ceiling is made of aluminum. The product worked perfectly! It was dry to the touch in about an hour. But I did use an industrial fan to help the drying process along. I would highly recommend this product despite the damaged to the exterior of the cans.
