Because I'm an idiot I specced a bare spruce ceiling + beams in our kitchen extension. This means I have to paint it with intumescent varnish which is a total pain in the ass and also doesn't improve the wood visually. The manufacturer have told me I can use a water based varnish during the process to improve the finish. Osmo top oil is sort of what my mind jumped to, but obviously that's oil based. What can I use that's water based, not horrifically expensive, and will do what top oil would?
