I have noticed a weird bleed through white paint on stairs.
Spindles and side boards were lightly sanded and painted with Ronseal Ultra Tough white paint.
Soon after yellow marks started to appear.
Some are on the previously varnished arreas, but many are where varnish was very thin or most likely not present at all.
I have removed a 3mm plywood with clover leaf cutouts from the size and yellow staining follow this patern where cutouts were (no staining where area was covered - no sun, no adhesive or maybe no smoke).
I have attached photos of the staining, but I'm wondering what is the best stain blocker to use.
No nonsense didn't seal it. I was thinking about Zinsser but they have several products and the best one dries in seconds which is probably not good for this area.
What would be your advise?
