Painting over knotted pine

[RobFJ]

I'm just starting to decorate a boot room where the ceiling and walls have been clad in knotted pine and then varnished. It was done about 30 yrs ago.

I want to repaint to a much lighter colour as well as fill in some of the gaps around the worst knots.

Any advice on how to proceed and preparation products in particular whether knot treatment would be required.

Many thanks

unless the knots are bleeding, which I doubt after 30 years, then give it a good sand back and then a coat of undercoat, fill the knots that your not happy with then second undercoat and top coat

If in doubt, Zinsser BIN will prime and seal anything.

Thanks guys for the advice - much appreciated.

The knots shows no sign of bleeding but I've got some left over Zinsser bin that I can use if I do come across any
