Very good. I use it on small cracks as long as they are not very deep, hairline, casings, holes from nails, and so on. Wherever I have applied it, it hasn't cracked anywhere. I will see if it withstands over time. I have eliminated the ready-made acrylic fillers for minor repairs and I haven't regretted it so far. It does cost more, of course, but you don't need much for small fixes. Those of you who don't have experience with fillers, etc., will find it a bit difficult. It is a tricky material to work with. You need to keep wetting the spatulas, and the material itself on the spatula, and apply it quickly because it dries.
