It does as expected. I used it to fill some cracks in my concrete driveway. Some areas started sinking a bit, so I attempted to fill a d bridge them to smooth the transition in those areas. Maybe it's possible with a few well placed coats, but on the initial application I let is drip from the highest edge to round out the sharp edge and fall down into the crack. While the height difference is still there, it makes it much smoother on the feet and less of a trip hazard. Flat gaps were quickly and easily filled. I'll be getting a bunch more of this stiff to finish up the larger cracks I have. Good stuff so far.

Works mostly as described. Purchased 5 pack and have opened 4 thus far. First 3 were perfect. The 4th packet was not leveling itself and had a thicker consistency out of the tube. I ended up leveling with a putty knife. Application cures very quickly without a mess.

El producto sí cumple con las expectativas es un adhesivo sellador que sí ayuda a sellar grietas principalmente donde hay movimiento sobre la superficie

Does the job. Fill the crack with a foam backer before use.

Overall this filler isn't bad. It was easy enough to squeeze out, though I prefer the style that come in caulk guns. It did shift a little bit in cracks where one side was higher than the other but not so much that it was running. I had one giant crack that was basically a hole and I mixed it with gravel and this filler and it seems to be holding up well. It's elastic enough I feel like it can handle ground movement. After a month, there's no pulling away from the edges of the cracks. I thought gray would match the patio. I was wrong. Oh well, it actually looks better with gray crack filler than all the sprouted weeds. There was enough in the package to do two yard-long cracks plus the hole and about six inches of another crack I didn't finish. The only issue I have is long after drying, the filler is still a bit tacky on the surface. That may be just due to what the material is made of and part of the feel of the finish, as it's not sticky. Dirt is already sticking there and not blowing off with the leaf blower, which may lead to more weeds sprouting in those spots

Fortunately I tested this indoors before pouring it all over my driveway cracks. Takes over 24 hours to dry in perfect conditions. After curing I did a stretch test and it just breaks apart. I can’t imagine this lasting more than a few months.
