  • Minimum 1.5 HP motor
  • Maximum speed of 175 RPM
• Release water and distribute the slurry evenly by moving the machine back and forth.
• Maintain a thick slurry consistency; avoid making it too wet.
• Polish using a spiral motion for approximately 2.5–4 minutes.
• Check the surface with a squeegee; a high polish should be visible.
• Rinse with clean water, vacuum the slurry, and clean with a neutral stone cleaner such as MB-1 Floor Amore or MB-15 StoneGlow.
• Repeat the process on the next section.

Countertop Application

• Work in a 3–4 sq. ft. area.
• Apply approximately ½ teaspoon of Ultra 5 powder.
