About 30 years ago I used Rust-Oleum spray paint to put a textured fake stone finish on a wooden nightstand for my young son's room. (It worked with this decor, trust me.) Now I want to be able to paint that nightstand for the guestroom using Benjamin Moore Advance Aklyd paint. But I need to get that surface smooth.
Do I try to sand it off? Will it even come off? It's been remarkable durable for 30 years with no visible wear - no chips, peeling, loss of little "stones".
Is there something to put over it to level it, fill in, and create a smooth surface to work from?
