Hello, I have never posted to this group in the past, but read when time permits. I now have a question. Our house was built in early 60s and the walls do not have a nice texture (old paneling was removed from one section). I want to re-texture the walls with this gun and hopper thing we have that hooks up to an air compressor. The walls have semi-gloss paint on them. Do these walls have to have something done to them (primer) before I do the retexturing? I fear that the mud will not stick to the semi-gloss paint. Or can I just spray on the mud, then prime, then paint?
Thank you very much for any comments.
