Bona Diamond Abrasive Discs deliver consistent scratch patterns across the entire floor, creating the best surface for optimal adhesion. These revolutionary discs prepare all polyurethane-finished floors for recoating, including hard-to-abrade ALOX and ceramic prefinished surfaces. Engineered to last 12 times longer than screens and other inter-coat abrasives, they provide exceptional durability and value. Their unique construction allows them to conform to the floor, ensuring complete abrasion and smoothing for a flawless, scratch-free finish on raw wood or recoats. Each set covers 4,000 to 6,000 square feet during inter-coat abrasion, reducing downtime and replacement needs. With no visible swirl marks, a consistent scratch pattern and improved adhesion for recoating, Bona Diamond Abrasives set a new standard in surface preparation.
