Easy to use.
Filling a crack in the family room, I smoothed this crack filler with my finger. It fills great and seems to be holding up well, only time will tell if it doesn't crack again.

Did not come out smoothly.
Seemed hard to use. This may have been due to type of caulk. I had to let the pressure off my caulking gun and then use the product that had been released. I would have preferred a smooth flow. I used another caulking over top of this to smooth it out and I was very satisfied when I finished fixing a large crack in my wall.

Why does it come in tube?
I don't like the tube, after cutting the tip to open the material didn't want to come out. After clearing out some harder stuff in the nozzle area the rest would freely come out. It dries hard so try not to build it up higher than you need. I put this in a crack and after drying I still had a crack. It may because I had filled the crack before with different material. the directions on the tube say it not for structural or stress cracks. I have to try some other cracks and see how they come out.

Lightweight Spackle in a caulk tube!
I read the bad reviews and thought the bad ones were just people who did not know how to use the product. So I purchased it anyway. This stuff is useless. A huge hole in the tip and a huge puncture in the foil seal are required to get it to flow at all. It spreads like spackle or joint compound, and is not very sticky. It is basically lightweight spackle in a caulk tube. I would give it zero starts if it was possible. I am surprised 3M even puts it's name on this junk.

3M crack sealer
Works but shrinks after drying. Have gotten some tubes that were almost dry and hard to work with not suppliers fault.

This product was a complete waste of money, it’s very slow to release from tube and it seems like it has already gone off not sure as to what year it was made as no clear date on tube. As for being value for money and easy to use and quality what a joke. Wouldn’t recommend this product to anyone, save your money and try something else!!! Rubbish.
