Hi.
We are repainting our house and are wanting to change all the skirting boards, window sills and bench tops from the vanished wood to painted white.
Looking for advice on best way to do this to avoid the underlayer bleeding through the white. Thank you.
Welcome to the Bunnings Workshop community @Emmzee. It's sensational to have you join us, and many thanks for your question about painting varnished timber.
@prettyliving is on the money. I'd be a bit more concerned about adhesion than stain blocking. Stain blocking is typically only needed for tannin-rich timber or when you are painting over heavily stained timber. You could either sand the high-gloss bench until there is no sheen and apply Zinsser 1L CoverStain Primer Sealer Stain Blocker, or you could sand it lightly and use Dulux 1L PRECISION White Maximum Strength Adhesion Primer. Being a shelf/bench that might see some wear, it's important that the paint is well-adhered, so that's why I'd be going with a primer for difficult-to-paint surfaces rather than a stain blocker. For your paint, I recommend something like Aquanamel and potentially overcoating it with Cabots CFP for additional protection.
Please let us know if you have any questions.
