Polyurethane varnish on top of water based varnish. Can I do this?
I have used water based quick drying varnish on a bare wooden front door which I now regret as I don't think it will be tough enough.
Would the water based varnish work as a primer or undercoat for a polyurethane varnish?
Thanks

Yes should do, I did beams in water based then decided I liked the sheen of spirit based & slapped it on top, no bother.

spirit based & slapped it on top, no bother.
is it the other way round when theres a problem? water paints on top of oil paint? [g]
With art you can put oil on top of acrylic but not the other way round. quite often oil paintings use acrylic for under coat.

Are you sure? My experience with water-based is that some of them are remarkably tough. However I have not used it somewhere quite as extreme as an exposed front door.
Hmmm... if you get it wrong you can come down the next morning and discover that you paintakingly created a craqueleur, entirely without wanting to.
