Varnishing MDF

[MadDoc]

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,

MadDoc, hi.

Would suggest that you use a scrap bit of your MDF, apply the finishes and the Varnish you note in your post an see what happens, trying this on a scrap bit of MDF rather than on your Project will give you an insite as to how it will all come together.

Ken.

Thanks Ken. I think that's what I'll do. I'd hate to wreck the project at the end.
