- As this recipe is simple black and white, it works best when creating line art. Using a water-jet cutter, cut out a set of full-size templates for your design.
- Shotblast the floor with Blastrac 1-15DS and S-460 steel shot to open the surface of the concrete.
- Clean floor thoroughly with a vacuum.
- Mix the Moisture Vapor Treatment and put down one coat of the product with a paint roller.
- Mix the dry-pack mudbed using the portland cement, coarse sand and Plex-A-Bond, at a ratio of 4 parts portland cement to 1 part each of sand and Plex-A-Bond. Screed the mixture to the proper elevation.
- Trace design on the mudbed using your template, and then affix your divider strips along the lines of the pattern.
- Mix Key Resin Epoxy, which comes as a two-part system, at a 5:1 epoxy-to-hardener ratio, and mix for 5 minutes.
- Add 25 pounds of Plus 5 as filler to help stiffen the epoxy mix. Let mix for 2 minutes.
- Add a batch of chips – half of them size 0 and half size 1 – and let mix for 3 more minutes. Pour mix on the floor and spread with a hand trowel.
- Let cure for 10 hours before beginning grinding and polishing.
- Start with a rough grind (dry or wet) using the 24-grit diamond segments. Make sure to make an even number of passes so the floor will be even and flat.
- Next, a medium grind with 80-grit carbide stones.
- Finally, a fine grind with 120-grit carbide stones.
- Mop the floor with clean water after the fine grind. Rinse and repeat a couple of times.
- Allow the surface to dry for 4 hours before applying a coat of sealer with a paint roller.
