I have never used shellac before. Always used lacquer and polyeurathane. I have always read that an advantage of shellac is you could spray a coat and it would dry very quickly (in 30-60 minutes) you could sand it down, spray again, etc. you could pretty much finish a small project in a day. So I tried it on a small project and I am finding it takes a long time to dry. I am spraying thin coats. Using a 2 pound cut. I didn't mix flakes with alcohol. It's Zinser. I live in Texas where it is in the high 60's to low 70's. This stuff doesn't dry even over night. Still gummy to the touch. Any thoughts or advice?
