We built a conservatory and rather than plain plasterboard inside we did it with wood cladding - looked great at first (almost white wood and a nice smell) - I varnished it with Ronseal waterbased varnish and after a few months the wood went a horrible yellow/orange tinge.
Q1 - Is there anyway of preventing this from happening
So wife complained (it was her who wanted wood in first place) and made me paint it - so rubbed down varnish - and applied satinwood with a small roller - again looked great - however after about 6 months all the knots have started to come through as black marks
Q2 -what can I apply to painted surface to stop this happening before redecorating - will i have to rub back to bare wood and apply knotting solution
