knots

[waggonway]

I have recently put up a pine tongue and groove ceiling. I now know I should have treated the knots with knotting solution before painting...but I thought primer, undercoat and two final coats of satinwood would have done the trick. Knots are now staining the paint any ideas about what to do to stop this?

Give it a coat of bin then recoat with your satin.
