A comment
A lot of scary information on the Internet about coating bathtubs with liquid acrylic. But, despite all this, I decided, and I called a specialist to restore my old bathtub with acrylic. I do not regret it, though a little less than 1 year has passed since the coverage. But, at the moment, everything suits me. The bathtub has become much more beautiful, I don’t even want to remember about its old appearance. It did not crack, did not deteriorate and did not turn yellow, in my opinion, rather, you need to choose the right organization. Plus, now it has become more pleasant to be in such a bath, the heat is kept excellent, it cools slowly.
Liquid acrylic is tightly connected to the bathtub, so I'm not at all afraid that it will move away from the bathtub (which cannot be said from the same acrylic liners). Liquid acrylic coating is not afraid of drops, scratches, moisture and light, I advise!
pros
Fast, cheap and practical.
