This means you need to sand it to take off the gloss, then apply wood undercoat (or combined wood primer/undercoat) to give a matt finish ready for the new topcoat.
Use knotting solution, which you apply only to the knots, or, better still, paint all the wood with Ronseal KnotBlock Wood Primer & Undercoat (from PS7.98 for 250ml, B&Q), which is water-based and nicer to use.
If the undercoat
takes in solvent and swells, a compressive stress will develop causing the coating to buckle in a manner similar to the skin described above.
Both new surfacers are part of the DuPont Refinish ValueShade technology platform which improves topcoat performance by applying an undercoat
in a shade of grey.
As well as two layers of undercoat
(pounds 6.99) slap on two layers of top coat.
Soak-in is the defect where paint sinks down into a substrate or undercoat
instead of forming a smooth, continuous layer on top of it.
Are you sure you used an oil-based undercoat
and top coat?
