Presentation Transcript

  1. Initial Grinding -Wet • Eliminate dust • Residue has to be captured • Floor has to be auto-scrubbed

  2. Initial Grinding - Dry • Dust has to be captured • Particulate can be used for patching • Floor has to be vacuumed • Honing and polishing • always performed dry

  3. Aggregate Exposure Classes

  4. Class A – Cream

  5. Class B – Fine Aggregate (Salt & Pepper)

  6. Class C – Medium Aggregate

  7. Class D – Large Aggregate

  8. Repairs • Holes • Surface damage • Air hole voids • Spalls • Small and micro cracks • Dust particulate can be • mixed with patching material

  9. Densifying • Denser the concrete, the better the results • Hallmark characteristic of polished concrete is that the surface is harder, more durable, and more stain-resistant because of the densifier

  10. Densifying Densifier reacts with excess calcium hydroxide to form calcium silicate hydrate to fill the capillaries left by hydration

  11. Coloring • Integral color in concrete mix • Water-based dyes • Acid stains • Solvent-based stains

  12. Honing and Polishing Ever increasing abrasive grits used to establish gloss levels

  13. Gloss Levels

  14. Reflective Clarity • Degree of sharpness • Reflective crispness of overhead • objects • Viewed 5 ft. above and perpendicular • ASTM D 5767

  15. Reflective Sheen • Degree of gloss reflected from surface • Viewed 20 ft. from and at an angle • ASTM D 4039
