- 01Mechanical Prep: Shot blast or diamond grind concrete to ICRI CSP 3. Vacuum dust completely.
- 02Pre-Mix: Separately stir Part A for 1 minute. Accurately measure 2 Parts A to 1 Part B by volume.
- 03Mechanical Mix: Blend 3 minutes with low-speed drill (350 RPM). Scrape bucket walls and bottom.
- 04Immediate Placement: Empty contents immediately onto slab in ribbons (exotherm risk in bucket).
- 05High Moisture App: Spread with 3/16" or 1/4" V-notched squeegee at 100-120 sq ft/gal (14–16 wet mils).
- 06Moderate Moisture App: Spread at 130-150 sq ft/gal (11–12 wet mils) for slabs up to 15 lbs MVER.
- 07Back-Rolling: Immediately cross-roll with 3/8" nap lint-free roller perpendicular to squeegee pulls.
- 08Pinhole Inspection: Inspect cured film for outgassing pinholes. A continuous monolithic film is mandatory.
- 09Recoat Window: 8 to 16 hours. Apply base coat within this window without mechanical abrading.
- 10Abrasion Window: If recoat window exceeds 24 hours, abrade with 60-80 grit sanding screen.
