Random late night ponder..
Going to put up a small picket fence, B&Q have ronseal on offer, is it decent or should I look at something else, I don’t really want to be re-proofing it very often.
Thanks

If it’s rough sawn timber that’s pressure treated, I’d use a preservative rather than a stain, not water based or ronseal though. Try your local decorators merchant, Johnstone’s do a decent one at a decent price

What does the tin say?

I’ve bought stuff from them in the past. Good advice given by them. Some of the stuff is expensive, but buy cheap, buy twice…
