  • Let floor dry completely before dry screening.

 

Dry Screen Disc

 

  • Work in small areas by laying the screen grit discs in a pattern of 10 feet by 25 feet (250 Square Feet).
  • Using a Single Disc 175 rpm floor machine equipped with dust control and a 120 grit screen on a white pad.
  • Inside these 10 foot by 25 foot sections of the floor, screen across the grain, then with the grain until all gloss is removed from the floor. Make sure you flip the grit screen disk every 250 square feet and replace with a new grit screen disk every 500 square feet.
  • Continue until the entire wood floor is completed and making sure to screen the gloss off the floor on the edges and corners.

 

Dust Removal

 

  • Using a vacuum remove dust from confined areas like edges and corners.
  • Using the automatic scrubber equipped with blue scrub pads and properly diluted cleaner to scrub the floor.
  • Allow the floor to dry completely and check floor for any glossy or shiny areas. If any of the floor areas are still glossy or shiny, screen disc the floor again until the floor is uniformly dull.
  • Once the floor is uniformly dull, tack the floor with a push broom and towels/cloth dampened with a Tacking Solution. Repeat tacking until floor is clean and dust free being sure to cover the entire floor including edges and corners.
  • Allow the floor to dry completely for 30 minutes before applying finish being sure to applying finish to the wood floor within 2 hours of tacking.
