Aqua Mix KnockDown Honing Powder

Aqua Mix KnockDown is a non-acidic, honing powder that removes light surface scratches, moderate acid etching, and wear patterns and produces an even, flat, honed finish. It is excellent for safely honing polished marble, limestone, or travertine to a smooth honed surface where a honed, unpolished finish is desired.

Aqua Mix No VOC (Volatile Organic Compound Formulas) help provide better indoor and outdoor air quality compared to similar traditional products.


Limestone, marble, and travertine.

Equipment Needed:

  • 1) 175 to 300 RPM floor machine or hand polish machine
  • 2) Natural hair or synthetic fiber tan floor pads
  • 3) KnockDown
  • 4) Protective plastic or blue painter’s tape
  • 5) Spray bottle of water
  • 6) Wet vac
  • 7) Mop and bucket
  • 8) Squeegee


Test a small area according to application instructions to determine desired results.

1) Read entire label before using.

2) Test in a small inconspicuous area to determine desired results.

3) Sweep or vacuum surface.

4) Protect baseboards, carpet, etc. with protective plastic and/or blue painter’s tape.

5) Surface must be free of existing sealers or coatings.

6) Liberally apply KnockDown to the stone surface.

7) Add water to form a slurry.

8) 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.

9) Keep slurry wet while buffing. Add KnockDown as needed. Harder stones will require a thicker slurry.
