Bona 5" Disc Siafast DIAMOND

Bona 5" Diamond Abrasive Discs are best in class when prepping any polyurethane finished floors for recoating. This even includes difficult to abrade ALOX and ceramic prefinished flooring. Bona Diamond Abrasives last 12x longer than screens and other inter-coat abrasive products. Each disc is designed to better conform to the floor surface which provides a more consistent abrasion and smoothing of heavy scratches. Can be used on bare wood for smoothest natural finish. When used in a set on the multi-disc sander, expect 4000-6000 sq ft on inter-coat abrasion. Packaged in pack of 12 and 48 per case.
