I sanded my banisters and applied wood paint (recommended by the worker in homebase) for first coat, lovely. Second coat on and it peels everything away. Why?
Gloss on top of gloss will peel in small sheets. Easy fix.. Solvent based undercoat to tighten up the paint and stop it running. Light rub down and then f funish coat
Did all the priming and undercoat nothing would work, got Poundlands wood paint for a fiver thought got nothing to lose🤷‍♀️went on a dream just one coat
Grease most likely, a degrease followed by a really good sand. Then appropriate primer and then top coats with denibbing (fine sanding) in between coats and removing dust.
