## Questions & Answers

**Q: Can this be applied on top of a layer of glossy paint?**
A: It cannot be applied over any water-soluble paint, including glossy latex paint. It can be applied over oil based paints.
Directions and warnings on the the can: 
"DO NOT APPLY over water-soluble paints or any material that is soluble in water such as calcimine, casein, glue size, wallpaper. DO NOT APPLY over frozen concrete or dead plaster."
"Glossy painted surfaces should be dulled with an abrasive."

**Q: What’s the remedy for plaster weld left too long on drywall  before plastering**
A: You can scrape or peel it off or just apply another fresh coat.

**Q: For use on closed-cell spray foam?**
A: I don't think so. This is "traditional plaster" that needs a mesh matrix to which to cling.

**Q: When can I paint over the new plaster?**
A: I worked only on weekends so my plaster set a week after I patched my wall. Then I sanded it and  then I applied a surface texture. The temp was +100 deg in the summers after 2 weeks I painted my wall. However, you should be able to paint after a couple of days of drying.
