Can I paint emulsion over varnish
If you ever thought of painting matt emulsion straight over varnish, then don’t!
This was acrylic matt emulsion from a sampler applied straight onto a varnished wooden kitchen door. The paint was 3 days old and “looked” solid. A quick rub over with wet n’ dry sandpaper turned it to sludge. An accelerated vision of a gradual self destruct peeling process where the paint has no key.
Ordinarily, paint needs a key. There are high adhesion primers that will stick to non keyed surfaces, but emulsion isn’t one such product.
Better to do nothing than slap the wrong paint on, without cleaning, sanding and priming! Of course, if you want to paint waxy furniture without too much prep, try Annie Sloan chalk paint. That is easy to apply, but like most things that work, it isn’t all “easy”, because you need some hard graft applying the wax for protection.
