Flex Paste Super Thick Rubber Paste, 8.75 fl oz, White

I had to cover up a couple of cracks so water wouldn't leak in and the flex tape helped keep the water out, it's a great quick fix. I suggest getting a putty scraper that's narrow enough to fit into the tub. Apply a thick enough coat, let it dry fully for a full day. Go over it the next day just for extra coverage. You have to read the directions and keep the foil on it and silica gel packets so the entire tub doesn't dry out. This is very important. It's a good price and I had some left over just in case I need it in the future. I recommend it!

Two different uses of the Flexseal paste I have never seen advertised. 1) I have used Flexseal to repair bicycle inner tube punctures rather than a cheap patch. Normal prep of the tube and a coating if the paste is all that's required tor an air tight seal and no issues. As a competitive cyclist, I have lots of training rides in less than ideal conditions resulting in several punctures. I'll usually collect several tubes and spend very few minutes affecting the repairs. 2) I'm currently replacing pool decking and installing composite decking over a concrete and paver pool deck. Over time, the pool deck has shifted and cracked and the surface is uneven and broken in places. I use Flex seal to help anchor the ends of the composite decking to the existing surface to keep the surface level and secure. Works well.
