used to fill a gap in the sidewalk expansion join. pros: easy to use. after cure time, the product is solid. cons: can be messy. Wish it was just a bit thicker and overed more coverage.

In terms of product performance, this stuff works great on expansion joints. It sealed the gap between my driveway and the road with a flexible, but dense rubbery material. Adhered to both side of the joint walls, too, so should keep water out. I finished by tossing some sand on the top of the smoothed goo, which helps hide imperfections. Now, the down side. The sellers are borderline incompetent or lazy. Twice my orders were lost and I had to cancel and reorder. Another time It was a week before they finally shipped my order. Bottom line, do not use seller if you have a time sensitive job, and their fulfillment effort is very lacking. Am giving a very generous four stars because the produce is good, but minus one star for poor customer service. I should deduct two, but I am feeling charitable today….

Product looks and seems very heavy duty, but it is very sticky and hard to tool , for a nice professional looking job

Good quality product. Found that set to touch sooner than other products I used. Easy to knife for smooth finish. Overall dry time seems to be longer than other products I used.

Product had an expiration date of June 2026, but had no problems. Flowed smoothly from start to finish.

excellent adhesion, tact time and coverage. i wanted to try this edge sealant for a long time. I used it on stem walls foundations to footings. the elasticity is more than I expected. This was a good practice being the inside edges of foundations. it’s really a protections if and ever an edge crack occurs to keep water from seeping into the footings/ rebar. I’ll probably use more along the outside sill plate to stem walls foundations to prevent long term bugs from exploring around.

Looks durable, flexible with good adhesion, however this is not self leveling and a bit thick, so you need to make sure scrape excess and level it before it hardens
