You don’t say if the varnish was water-based or not. I suspect as previously said it has gone on a bit thick, first coat should be thinned a little, the varnish doesn’t need rubbing down as such it just needs the little specks removing with a specialist de- nibbing paper which can be completely worn out to work best, quite amazing stuff, you can rub your hand over the dried varnish and think oh God what a mess, and then 30 seconds later with something that you think won’t do any good at all and it’s like satin, and ready for another coat.Don't know if you can help but I have just finished varnishing a desk I made for my son and was not pleased with the finish I obtained, reached the level of "it will do". Being new to this I followed the instructions as best I could. On hardwood ply, wiped down with a white spirit damped cloth to remove dust, stained with a water based stain, two coats of Ronseal polyurethane satin 6 hours apart left 24 hours sanded with 240 paper then top coat. Result brush marks, orange peel and some visible scratches from sanding. Following unsatisfying results on the underside as an experiment preped as before then when the first coat was dry scrapped it with a Stanley blade and applied one further coat, much better finish no brush marks, fairly even shine, not up to the standard in your photo but wouldn't expect that on my second attempt.
What puzzles me is why am I getting a better result going away from the method used by people who obviously know more than I do. Any idea what I'm doing wrong?
One thing about Johnstons water-based varnish, on the instructions it says do not overlap the brushstrokes – lol, I think the people that wrote that have never actually vanished anything in their lives, I overlap, brush it in the other direction and back again with the grain and it always comes out perfect, don’t know what they’re on about really.
Edit, I don’t know if it will make any difference, but I never use white spirit to remove dust, just one of those household dusting cloth‘s that when you pass it over a sanded surface, pick up an incredible amount, also anything that’s missed gets removed with the de-nibbing paper. Ian
