I stupidly thought I could paint my daughters pine loft bed with white gloss without needing an undercoat/primer as it’s not untreated wood, it has a factory applied matte varnish type surface. I’m horrified after painting it in white 1 coat of gloss that its just scratching off with my finger nail and hasn’t bonded! Everything I’m reading is leading to me needing to scrape the gloss paint off and start again but as the tiny room is only a foot longer than the bed which was horrific to put together and I’m having to work in a cramped area, unless I take down the bed again. I’m really not happy to have to sand the bed and am wondering if there’s any way to sort out this mess without having to take off all my hard work?
This is a major bummer. First, give the paint a couple of weeks to see if it will bond. The bond between a surface and the paint increases as the paint cures. Curing takes 3-4 weeks, typically. Plus a gloss cures slowly.
If there is no or little bond then yes you will need to remove the new paint, sand the surface then prime it before applying a finish paint. It might be best to take the bed apart and do some of this out side.
