Improperly Prepped Paint Peels Off Easily

this vanity was originally white . To update the powder room and coordinate with the new wallpaper , the vanity cabinet was painted this rich green . When hanging wallpaper , some paste will get onto the woodwork or cabinetry . Usually, it’s a simple matter to wipe this paste off with a damp rag (we like microfiber cloths ).

But as you can see, even gentle wiping with a damp cloth has taken some of the new paint with it. This is usually because the new paint was applied without having properly prepped the original surface. The original paint has a gloss / sheen , which makes it attractive , as well as resistant to dirt and stains . But new coatings (be they paint , latex paint , wallpaper paste , etc. ) won’t adhere tightly to a glossy surface .

So it’s imperative that the original surface be prepped correctly , before the new paint is applied . This means de-glossing . Deglossing can be done by sanding the surface to scruff it up, which will give a bit of “tooth” to the surface for the new coating to stick to. Or you can buy a chemical de-glosser from a good paint store like Sherwin-Williams or big box store like Home Depot . This is simply wiped on with a cloth . You can also use what’s called a bonding primer , which is formulated to adhere to just about anything , and then provides a surface that paint or other coatings can grab a hold of and stick to .
Once the original surface is properly de-glossed and primed and prepped , the new paint can be applied . Once that dries and cures , you can put stress on the surface, such as rubbing or wiping , without fear of the new paint peeling off .

Another weird thing is that the green color came off on my microfiber rag . I’ve had this happen with water-based / water-borne paints – but not with the old-fashioned oil-based paints . Not a big deal. Not enough of the color wiped off to cause any lack of color on the painted surface of the vanity . install
