Staircase glossing gone wrong... advice please

[mezibella]

Hi we have painted our stair case that was bare wood. We used an oil undercoat and gloss to finish, four coats of each. We still get a yellowing bleeding through. Im thinking we should have primed the wood before undercoating.

To solve do I

A: Sand back to bare wood & apply a primer, then undercoat & gloss. (Please No

B: Lightly rub back the gloss to form a key, add a primer, undercoat & gloss.

I am very tempted to rip out the whole lot and fit a nice clean new bannister however I've just spent a fortune laying new flooring so trying to avoid extra expense for the time being.

What a fook up. You should have used water based primer/undercoat and ideally waterbased sikkens satin. You are going to have to leave it for ages now to fully harden up.

Did you put knotting solution on the knots in the bare wood?

If not, the sap will bleed through, and you will have sticky yellow spots everywhere.
