HMK® 727 Re-Polishing Powder restores the natural shine of all dull calcareous stone without coating the surface. Deep scratches and acid etch marks may be restored by first sanding the natural stone surface, then using P727. This task is best left to the professional. Unlike new re-polishing methods, such as crystallization and vitrification, P727 has been factory and field proven for decades and is therefore known as the only "non-hazardous" Re-Polishing method. Furthermore, these other methods frequently contain ingredients that cause efflorescence, discoloration, and permanent burn marks.
Note:P27 is not effective on granite, resin based agglomerate, or any other material devoid of calcium carbonate. Darker natural stone usually does not polish up well or as easily as lighter colored stones.

Proceed with Care! First clean or strip area to be restored with HMK® R155 Intensive Cleaner or HMK® R154 Stripper/Satin Remover, depending on situation. Protect all adjacent masonry and non-masonry surfaces, since P727 contains acid. Mix R155 with clean water, about 1 part R155 to 10 parts water, and wet surface to be refinished. Allow to soak in for a few minutes. Sprinkle a little of P727 onto surface, enough to give a creamy/milky consistency when buffing. Do not allow solution to sit or dry on surface. Instead, start immediately with the buffing action. Add more water or powder as needed. More control can be achieved by pre-mixing P727 with water and R155 solution in a container. Use a hand-held radial buffer at 600-800 rpm for small areas or a regular floor machine at 175 rpm with a tampico brush or a white/tan polyester pad. Move machine slowly and evenly, doing small, manageable areas at a time. Buffing action may take 1/2 to 2 minutes to create shine. Check refinishing progress approximately every 15 to 30 seconds to prevent permanent burn marks.
Note: When interrupting buffing action, to check results, immediately pick up P727 solution to avoid acid burn marks. Place floor machine on a plastic sheet to avoid same. Repeat buffing and rinsing action as needed.

Toxic Solids, Organic, n.o.s. Poisonous. Protect skin and eyes. Use protective gear. If exposed, wash or flush with water. Keep out of reach of children. See Material Safety Data Sheet.

Store in cool place. Keep lid tightly closed.
Testing in an inconspicuous area is in every case imperative! The re-polishing success depends on the calcium content in the stone and the proper combination of the following: Dilution of P27, weight, rpm of the floor machine, and duration of buffing action. Trial and error will provide proper buffing time.
