BonaKemi USA’s latest innovation, BonaTech Prep, is a recoating adhesion system for hardwood floors. BonaTech Prep is Bona’s solution for the problem of recoating the new aluminum oxide and ceramic-type finishes used on prefinished hardwood floors, as well as all urethane-finished hardwood floors. The system not only prepares the surface to ensure adhesion, it removes scuffs and scratches by using a buffer and Bona Conditioning Pad with BonaTech Prep to abrade the old surface, the company says.
