Varnishing gone wrong - help please.

It's nothing to do with the temperature. I have used Ronseal in temperatures close to zero. Beech is quite an oily wood and I suspect its the same effect as with teak. (and the iroko table I am typing on) Just keep going and subsequent coats will dry quicker.

Second coat has dried within 3 hours.

It may be....that the brush used was not perfectly clean and contaminated the application.

I have a technique for cleaning brushes used to varnish as follows:

I take chunky glass (like a whysky tunbler) and into this I pour a 50 / 50 mix of white spirit and washing up liquid (say about 3 tablespoons of each).

Then I rotate the brush in this mix to get all the bristles right to the root affected.

Then brush under the tap to rinse off and the glass likewise.

The operation is repeated 4 or 5 times.

The bristles come out like new.
You have to make sure the fibres are separated.

Shake excess water out of brush and leave to dry naturally, works a treat, preserves brushes in top condition for years of repeated use.

Yep pound shop brushes do that

Scrape it all off, even when left to dry, it will go all crinkly wrinkly (technical term, means looks like 5h1t. Sanding won't take it off, it just loads the sandpaper, scrape back to bare wood and re-sand. Start again.
