Application Method:

USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product. Read entire label before using. Test in a small inconspicuous area to determine desired results. Sweep or vacuum surface. Protect baseboards, carpet, etc. with protective plastic and/or blue painters tape. Surface must be free of existing sealers or coatings. Liberally apply KnockDown® to the stone surface. Add water to form a slurry. Refinish using a weighted floor machine fitted with a natural hair or synthetic fiber tan floor pad or use a hand polishing machine. If lippage is present, use two pads, double stacked. Keep slurry wet while buffing. Add KnockDown® as needed. Harder stones will require a thicker slurry. Buff area until the desired level of hone has been achieved squeegee slurry from a small area to check for desired results prior to removing slurry. Rinse well and use a wet vacuum to remove all excess compound.
