Dear Bob,
I have searched high and low for an answer to my question to no avail - I hope you can help. I have a building with exterior cladding in stucco on top and permastone on the bottom. My question is, can this type of siding be painted or re-coated in some way? It seems to me that it would need to breathe and painting it could cause a problem if the paint "closed its pores" so to speak. The reason I want to paint or re-coat it is because it has developed expansion and contraction cracks - vertical cracks throughout the "stones". I have caulked the cracks for now with a flexible cement colored caulk to protect the structure from the elements; but the cracks and caulk are very obvious due to the permastone being multi-colored. This house would look great if I could re-coat or paint the permastone one color, thereby camoflouging the repaired cracks. I can find no information on line about re-finishing, repairing, or painting this type of siding. Can you advise? Thanks, kb
