Quikrete 8660-30 Polyurethane Self Leveling Sealant, Gray, 29 Oz

I used this on the concrete around the pool on all of the concrete joints that had cracked. This stuff is great and easy to use. Flows very easily (not like regular caulk) once cured, turns into a rubbery extremely strong material. Do not over fill, you want this product in the joint filling cracks but not above the joint itself.

Ended up returning most of this item. Color didn't work for my project.

We have tried several different types of sealers for the cracks in our driveway. This one has worked the best first used it three years ago and it is still holding up. Just finished sealing several long and wide cracks again. Love the self leveling since I am not the steadiest at applying it. We live in Rockies and it gets cold and hot in the same day. The caulk seems to expand and contract and still maintain the seal.

Worked exactly as needed, easy to use

The price shot up. Should be at least 50% less than current asking price.

Tube appeared to be normal, but edge opened up when pressure was applied, causing it to burst, sending contents all over the concrete driveway. Packing was inadequate and lacked proper cushioning for shipment.

If you have cracks and expansion seams on concrete floors, this self leveling polyurethane compound is great. Good adhesion and complete sealing. Be sure to use backer rod to fill most of the space on seams and large cracks. Backer rod means you use far less on this compound and also prevents three point adhesion in expansion seams.

Used this to fill the joints in our driveway that had been previously filled with wood strips. A lot of back breaking work to get the wood out but this selfleveling sealant is wonderful and a lot cheaper than the poly strips you can push in---and this will last longer as the strips are only guaranteed for 5 years.
