Sticking to a Glossy Surface

Not many materials like to stick to a glossy surface. So today, when I had to skim-float a wall to smooth it, in order to help the joint compound adhere to the existing paint, I first wiped the wall down with Liquid Sandpaper – a chemical formulated to knock off the gloss and prepare the surface to accept the coating you are wanting to apply on top of it.
