Tremco 45SSL Vulkem Polyurethane Semi-Self Leveling Sealant, Gray

Absolutely the best free flowing, self leveling driveway sealant. Better than any crack repair in the hardware store. This stuff will fill the biggest cracks, especially when used with a back bar (foam insert). You can remove the old felt-like spacer and refill the space with the backer bar and this sealant, or use just the sealant if the gap isn't too deep. Works like a charm. Dusted with sand while wet, it blends in well with a regular concrete driveway, and even better with aggregate walks. Buy it!

The way it was packed the tip of the caulk tube got bent and the product leaked out. Sounded like a good product that unfortunately is unusable

This sealant is self leveling, like another sealant I've used before. I chose this sealant hoping it will last longer than the previous item.

Not only had product leaked out, but I couldn't even put it into the dispenser and had to return the item

It is very easy to use, and produces a professional result. I would have given it 5 stars except for the fact that after several temperature changes, I have noticed a couple of places where it is separating or cracking. It still is the best caulk I have found so far.

Worked as advertised and it was exactly what I needed for my project

This is a 30 ounce tube. I didn't see that anywhere, in any review. Figured I would add that info to my comment.I had to run out to Lowes and get a larger caulk gun, the one I had would only handle the standard 10 ounce caulk tubes.So today, I am out caulking the pool coping, waiting to see how the first layer works out. The coping backs right up to a concrete pad. The builders did not leave any gaps to caulk. What I am doing today if filling the gaps that time and weather have created.I will probably update this later, so far so good as far as the product goes.The folks who sent this, well they get 5 stars. I got this in no time. It was very well packed and arrived in good shape. THANKS!!!!

If you think your getting something thicker than Sikaflex you can buy anywhere and everywhere don't wait or waste your time with this. Flows the same....
