E-SDSConcrete Crack Repair Sealant Self Leveling Gray Polyurethane Construction Sealant Sealing Horizontal Expansion Joints in Concrete 10.5 fl. oz (6 Pack)

Got it fast. Got it in good condition. got it like the picture.

I used this for some concrete crack repairs in addition to holding some pavers in place. This stuff works great but depending on how much you put down (thickness wise) it takes a few days to dry. It is very flexible and seeps into the cracks very quickly. I used it as a preventative maintenance product to seal up cracks before the winter gets here and tries to destroy expensive concrete.

UPDATE: I had gone beyond the return window when my batch of tubes proved to be seized up and worthless, BUT the seller reached out anyway and gave me a full refund. Went from 1 star to 4.------I bought these as part of a project to repair a crack in my house concrete pad. First I needed to inject (expensive) 2-part epoxy glue with bolts every few inches along it and then I planned to use this product to fully seal the top of the crack. I bought this a few weeks early and kept it on hand so that when the prep work and epoxy glue had fully cured, I'd be ready to go.When I punctured the inside foil seal on the first tube, I could tell the product was semi-liquid. BUT when I started working the trigger on the gun, the inner end would not budge. I thought, "oh well -- good thing I've got 3 tubes!" Not so fast. Each one of them was frozen in the tube. I took a rubber mallet to the back angled plunger, and then a heavy hammer, but those tubes were totally seized up. Unfortunately, I also bent the plunger and the sheet-metal trigger trying to get the product out. Good thing caulk guns are relatively cheap!I'm past the 30 day return window and so I've wasted my $30 plus the gun.Frustrating!

This driveway crack sealer was very poor. Only one tube of the six sent was usable. The other 5 tubes would not release sealant when using the tube gun. Amazon replaced with 6 tubes from a different manufacturing lot. All six worked fine from the replacement lot.

The product came in 3 regular caulk size tubes with screw on tips. It is thinner than caulk so it flows into smaller cracks perfectly. Larger cracks may need foam packed to prevent the product from flowing out. It may be a little raised when used on hairline cracks, which is fine with me as long as it keeps the water out. It drys a gunmetal gray, and goes a long way. We are supposed to have a cold of wet winter and this product appears to have good adhesion and sealant properties.

Difficult to dispense from tube. It stayed tacky for days. It has actually not firmed up really at all. It did dry from being tacky. However its sticky and attracts dirt. Difficult to sweep over. Just to tacky.

I am using it to fill a gap between the house and a sidewalk. The self-levelling works great. You may need to reapply more if the crack is deep because it will settle to the bottom of the crack which is the desired state. I am trying to prevent water from entering the crack so this means it will form quite a solid bond.

Awsome product. Easy to use, it makes crack repair a snap
