Review on Gorilla Waterproof Patch & Seal Liquid - Black 16Oz - Ultimate Solution For Quick Fixes (Pack Of 1) by David Grajales

This clear sealing product is easy to use. It will keep spreading/flowing for a few minutes after it is applied to the surface. It does a good job of flowing into cracks, before curing. The curing process took a full 24 hours before it was completely dry to the touch. It stopped every leak in my 1950s concrete wash tray, in my garage.One thing to note. When the product is completely dry, then exposed to water, it turns whitish, but it doesn't seem to loosen the adhesion. Applied this product over 5 months ago and it's still working fine.Worth the price for ease of use and durability.I would but it again.
