CrystalClear 500% Elastic Waterproof Coating - 1 Quart - Self-Leveling Liquid Rubber Sealant for Roofs/Pools/Bathrooms - UV-Resistant & -40°F to 300°F - Professional Leak Repair

Goes on smoothly and sealed up the cracks on the basement walls without trouble. It’s been holding strong after rain.

This is an excellent product.The tubs are very welled sealed. No risk of spills.waterproof sealant claims to be a versatile and effective waterproofing solution both indoors and outdoors.I highly recommend this product as it’s easy to use and seems to hold up well so far.

but it does a pretty good job on the old yellow rain slicker. Just be careful not to sit on anything until it’s dry. I was unsuccessful at getting it off my car seat.

This sealant saved my leaking roof! The 35oz black formula is 3X thicker than others—applied easily with a brush, forming a rubbery waterproof layer. Sealed cracks in concrete and stopped gutter leaks. After 6 months of rain/sun, no peeling or cracking. Professional-grade but DIY-friendly—even covered 120 sq ft with one jar!

This stuff is not elastomeric at all. In fact it is thinner than cheap white latex paint. I was expecting a thicker elastomeric coating. I'm using this on large hummingbird feeders. Over time, the plastic feeders crack because of UV exposure. I then repair with epoxy, then normally coat with a flex seal or gorilla liquid rubber sealant. Have also used both on lining gutter connections when they leak. My problem is when I seal the cans of flex seal / gorilla, the cans eventually bend, and the lid won't seal. So half the product becomes hard. Quite frankly I bought this because it looked liked it had a screw on top vs. a metal can with a lid. I've put on 8 coats, wasted 8 brushes and it is still not as thick as 1 coat of flex seal / gorilla. Don't waste your money. You are better off buying a gallon of cheap latex paint - and it has better coverage. This stuff is worthless.

No rain yet, so I'm not sure it has waterproofed the area of the roof I was concerned about, but we'll see. It was easy to paint on with a paintbrush BUT it's not white at all, but a kind of yellow-brown-white color that looks like dirty white. Not very good looking. I may need to paint over it with another brand of white roof sealant.

If all steps of followed, went on slick and easy so far looking good big rain storm today no leaks

Bought it for garage cracks, but it became my household hero! Coated my roof twice—it withstands scorching sun and hail. Sealed my fish tank's edges—no leaks in six months. Even waterproofed plant pots to prevent root rot. The sleek black finish looks pro-level. Now, whenever there’s a leak, I just grab this trusty can and say, "Problem solved!"
