Circular Floor Edger and Sander Discs
For beginners and those less experienced using floor sanders, sanding discs for floor buffers are usually a better option for sanding and refinishing floors than a drum sander. These discs are more forgiving on the floor’s surface and less likely to cause grooves or valleys that a drum sander might create.
Empire Abrasives carries an assortment of floor sanding discs in a variety of sizes, abrasive materials, and grits for whatever floor sanding job you plan to take on.
Hardwood Floor Edger Discs
These flooring discs are made to fit edger machines to sand floors all the way up to the edges of the walls. If using a drum sanding machine on the floor, there will be a gap between the edges of the floor and the furthest point the drum sander can reach. The edger discs close that gap and sand flush to the edges.
Concrete Sanding Discs
If you are looking for a circular floor sander that can sand concrete floors, the abrasive you should consider is silicon carbide. Silicon carbide grains are sharper and harder than zirconia, making them optimal for concrete. You can also use this type on hardwood floors as well as drywall, tile, marble, glass, and stone.
Sanding Over Coated Floors
Silicon carbide flooring discs can be used to sand and remove polyurethane, varnish, shellac, or paint from hardwood floors. The discs are load-resistant, but you may need additional discs when sanding coated surfaces because paint or varnish embeds into the abrasive faster than wood or concrete alone.
Mesh sandscreen edger discs and floor sanding screens are waterproof and more resistant to loading than coated abrasive varieties.
