6. Objectives Overview of Polished Concrete The Process Features and Benefits of Polished Concrete

7. What is Polished Concrete? Polished Concrete is a practical, decorative and economical floor system for any facility. Polished Concrete is becoming one of the fastest growing products to ever hit the flooring industry. Polished Concrete is a multi-step mechanical grinding & polishing process that utilizes industrial diamonds (tooling) & concrete densifier to level, densify, polish & finally seal the floor from within the interior of the floor surface.

8. Where can it be used? Recommended for use wherever a dense, wear resistant, architectural pleasing low maintenance floor is desired. • Manufacturing • Institutional Facilities • Commercial • Residential • Warehouses • Convention Centers • Sports Arenas • Airplane Hangers • Airport Facilities

9. The Origin of Polished Concrete Discovered in Tunisia by a granite and marble contractor Had utilized wet grinding and polishing on those surfaces and found it successful on concrete Mistake made and concrete was polished DRY Contractor using equipment from Scandinavia Brought to US in early ’90’s

10. The Equipment

11. Diamond Grinding Segments (Metal Bonds) Diamond Polishing Pads (Resin Bonds) The Equipment

12. The Process Ensure floor is clean and dry Concrete must be a minimum of 28 days old Minimum compressive strength of concrete should be 3,500 psi (24 MPa) Dry process – no water added during grinding or polishing Certified applicators/contractors

13. Step 1- 80 Grit Metal Bond Grinding Segment

14. Step 2- 150 Grit Metal Bond Grinding Segment

15. Step 3 – Concrete Densifier application

16. Concrete Densifier – Why? Silicate technology Hydration of concrete produces calcium hydroxide (free lime) Chemically coverts the free lime to calcium silicate hydrate (CSH) producing a dense surface To protect the integrity of the surface Does not allow the floor to erode, micro-pit or scratch Maintains the light reflectivity and shine

17. Step 4 – 100 Grit Diamond Resin Polishing

18. Step 5 – 200 Grit Diamond Resin Polishing

19. Step 6 – 400 Grit Diamond Resin Polishing

20. Step 7 – 800 Grit Diamond Resin Polishing

21. Step 8 – 1500 Grit Diamond Resin Polishing

22. Step 9 – 3000 Grit Diamond Resin Polishing

23. Sealing / Protection Cut down version of densifier Silane Siloxane mix Thin Clear Epoxy Silicone impregnators Specifically designed proprietary enhancers

24. Types of Finishes 800 GRIT : SATIN FINISH THAT WILL REFLECT IMAGES FROM SIDE LIGHTING. 1500 GRIT : SEMI-GLOSS FINISH THAT WILL REFLECT OVERHEAD AND SIDE IMAGES FROM 35-45 FEET WITH INCREASED LIGHT REFLECTIVITY. 3000 GRIT : HIGH-GLOSS FINISH THAT WILL LOOK WET AND SHOW MIRROR LIKE REFLECTIONS OF SIDE AND OVERHEAD IMAGES.

25. 800 Grit Satin Finish 1500 Grit Semi-Gloss Finish 3000 Grit High Gloss Finish Types of Finishes

26. Benefits of Polishing Elimination of Dusting Due to free lime (efflorescence) Vapor drive from below forces free lime to surface Can cause adhesive and specialty floor failures

27. Stain Resistance Reduces the porosity of the floor in conjunction with densifier Densification process is a chemical reaction, stain resistance not immediate Slows down penetration of water, oil and other contaminants Benefits of Polishing

28. Restoration of Older Floors Rain damage, spalling, pitting, delamination, floor failures Removal of top surface and harden the concrete below Deteriorated concrete can be strengthened Impact and abrasion resistance of the concrete can be increased Benefits of Polishing

29. Better Lighting Reflectivity of the floor Can reduce lighting costs Benefits of Polishing

30. Slip Resistance Measurement of coefficient of friction and slip resistance Exceeds OSHA standards for floors Exceeds ADA (Americans with Disabilities Act) Higher degree of polish is not directly related to slip resistance Benefits of Polishing

31. Less Maintenance Reduced penetration of contaminants, remain on surface Tire marking significantly reduced No sealing, waxing or stripping of floor required No aggressive scrubbing required Benefits of Polishing

32. Reduced Tire Wear Smoother concrete surface can significantly reduce tire wear Benefits of Polishing

33. Timing of Installation Applied after 28 days – no extended time frames between finishing and applying as with specialty coatings Non-toxic – can be applied while building is still occupied Densifier used in process – approvals through CFIA for use in food handling facilities Benefits of Polishing

34. Cost Effective Relatively inexpensive application costs Low maintenance costs One time application – no replacement costs as with specialty flooring systems Benefits of Polishing

Cost Comparison of Various Flooring Treatments   Vinyl Sheet Flooring* Carpet* Vinyl composite Tile* Epoxy Terrazzo* Epoxy Coating Polished Concrete               Cost / square foot Installed $2.72 $1.93 $1.23 $9.10 $4.00 $5.00 Annual Maintenance Cost / sq ft $1.39 $1.53 $1.47 $0.46 $0.50 $0.50 Replacement Cost $3.43 $2.24 $1.60 $0.00 $7.00 $0.00 Frequency of Replacement (years) 9 10 15 20+ 6 20+ 20 Year Cost $37.38 $39.39 $34.06 $18.30 $24.29 $15.00 Annual Cost / square foot $1.87 $1.97 $1.70 $0.92 $1.21 $0.75               20 year cost for 10,000 square ft. $373,800 $393,900 $340,600 $183,000 $242,900 $150,000 *information taken from commercial flooring life cycle cost analysis as provided by The National Terrazzo and Mosaic Association. The 20 year cost includes initial cost, replacement and maintenance costs

36. Cost Comparison of Various Flooring Treatments

37. Benefits of Polishing Long Lasting One time application Minimal maintenance required to preserve the appearance of the floor

38. Polished Concrete is developed to be a part of your sustainable design. Meets low emissions – no VOC Virtually dust-free process Increases ambient light – saves energy Local manufacturing of materials High Performance System Meets ADA/OSHA/CFIA requirements Earn credits towards LEED Sustainable Design

39. LEED Assist with LEED credits/points Areas: MR (Materials & Resources) IEQ (Indoor Environmental Quality)

40. LEED How does it assist with LEED credits? This process: Reduces the amount of construction waste Reduces the cost of building maintenance Reduces the cost of operation Reduces the amount of construction materials Preserves the recyclability of concrete Reduces airborne dust particulates Safe for the contractor and personnel Does not off gas Contains no VOC’s Extremely long-lasting
