Facing a nasty, peeling, paint-splattered old deck? Stripping it by hand or with chemicals is a nightmare. This Diamabrush tool attaches to a standard 5/8-11 angle grinder and makes the job way faster. It's a 4-1/2 inch diameter brush with super aggressive, stiff bristles (it's not for sanding – it's for stripping). It tears through old paint, stain, and weathered wood to get you back down to bare wood in one pass. It's chemical-free and does the job of both removing the old finish and roughing up the surface so new stain or paint will stick better. It works on textured coatings and flat surfaces. For the cleanest job and to protect your lungs, they recommend using it with their matching metal dust shroud that connects to a shop vac. This is a pro-grade tool that DIYers can rent or buy to totally transform a deck, fence, or other exterior wood surface in a weekend. It's tough, it's fast, and it saves your back.
