I am confounded by an inability of both polyurethane and Behlen’s Rock Hard table top varnish to adhere to some nightstands I made 20 years ago. At that time I used a homemade oil/varnish wipe-on finish. I now would like to do a varnish finish completed with pumice and rottenstone. First I rubbed the pieces with naptha to get any wax residue off. I then brushed on a coat of Behlen’s varnish. It took three days to dry and could be easily scraped off. I decided to completely strip the pieces with the nasty kind of stripper and try a few samples. I should point out that the surface is pretty smooth, and has not been scuff sanded. Small applications of Behlen’s and poly both still scrape off easily, but at least the poly dries in 24 hours.
