I have built an arcade replica out of MDF. I've given it two coats of MDF primer and two coats of satin black emulsion. It looks nice. I'd like to protect it with a coat of varnish but I wanted to make sure that you can varnish over emulsion with a water-based varnish or not? Something like the Ronseal diamond hard floor varnishes? Is this OK? I really don't want to spoil my pain job and resand it all! If it's OK, is it best applied with a roller?
Thanks in advance,
