The first stage of floor restoration is removal of lippage. Since this can only be accomplished by grinding the floor flat with an aggressive metal bond diamond disc, Alpha Professional Tools® introduced a lippage disc designed specifically for this application. Alpha® Advantage Lippage Discs consist of a group of metal bonded pellets imbedded in a resin compound that contains a sub-abrasive grit on a rigid pad. The resin compound prevents pellet loss and chipping of the stone. The sub-abrasive in the resin compound keeps the metal bonded pellets sharp for consistent performance. Floor restoration workers will love the aggressiveness of these discs. Designed for use on the AFP-300’s 17” driver pad, a minimum of 3 discs for each grit are required for the system although as many as 6 can be used for best results. Used wet and hook and loop backed for easy application, the Alpha® Advantage Lippage Discs are long lasting and provide the initial steps that result in a superb finish. Available in 2 grits, 60 & 150, these discs are the best discs for removing lippage and making the floor completely flat. If you do floor restoration, these discs are a must for you.
