Review: Much better than I expected. - This sounded too good to be true, but it's actually easy to use, and does a nice job filling little cracks and holes. I'm a renter, and have found that if I complain about little problems I might get an increase in my monthly bill. But, I was afraid bugs would make winter homes in the cracks around my door way. This isn't an elegant fix by any means (probably could be if someone wanted to take a lot more time), but it fills in openings in just a second or two, and I found it very easy to use.
Review: Good stuff — EZ application & EZ cleanup - Like a large tube of thick toothpaste but grainy - super EZ to apply; perfect consistency; not runny, not too thick. I’m ordering more. Color is lighter than I’d like; a light gray, not quite as dark as cement. Simple clean up. Caution though, it starts to dry rather quickly so smooth it out quickly so you don’t have to go back a second time Time will tell how it holds up, but price seems fair. So far, very pleased

### ⭐⭐⭐⭐ So far, so good
*by S***E on September 2, 2022*

Used this to patch a moderately large chip in a sidewalk. Wish they sold a smaller pint size since I didn't need this much. This is the smallest size you can get as far as I know, which is 1 quart or 4 cups. It comes in a plastic tub container with instructions to use a screwdriver to help you open and a hammer to close it. You can open and close it by hand, but I get why it might sometimes arrive open by mail since the plastic lid is easy to deform if something lifts it up. My plastic tub arrived fine and the material was not open or dried out. I got the package with the plastic knife set. You could probably buy this cheaper in a big-box store, so you're paying extra for the convenience of delivery. It's a lot lighter in texture than I was expecting. Other reviews call it "fluffy," which I would agree is the best description of it. I thought it would be denser, but it has the texture of cake mousse. I do wish it was a little denser so it would be easier to scoop and pack into deeper cracks. It does have a tendency to stick a little to gloves and spreading implements. I used the plastic knife set, but maybe it's easier to spread with a metal knife. I was worried it wouldn't set due to the texture, but it seemed pretty hard and dry 24 hours after the patch. I did apply it on a summer day where temps were between 70s and 80s. Didn't shrink, but it seemed to sink down a bit and "level" into the crack after 24 hours. I could probably do another layer, but I'm waiting to see how it holds up to rain and whether it will "melt off" like some negative reviews mentioned. So far, so good though.
