6 3.02 PREPARATION A. All concrete surfaces must be sound, solid, cleaned and primed: 1. All concrete subfloors must be of adequate strength, clean and free of all oil, grease, dirt, curing compounds and any substance that might act as a bond breaker before priming. Mechanically clean if necessary using shot blasting or other. B. Joint Fill 1. Honor all joints up through the ARDEX PC-M, including expansion joints, isolation joints and control joints (saw cuts). 2. All moving joints shall be filled with ARDEX ARDISEAL RAPID PLUS. 3. All non-moving joints shall be filled with ARDEX ARDIBOND AP, ARDEX ARDIFIX or ARDEX ARDISEAL RAPID PLUS. 4. For joints to be filled after the polish process, contact manufacturer for specific recommendations. C. Pinhole Filler (on ARDEX PC-T Polished Concrete Topping) 3.03 PRIMING 1. ARDEX PC-M can be used as pinhole filler on ARDEX PC-T Polished Concrete Topping. Please see ARDEX PC-M Technical Data Sheet for complete pinhole application instructions. 1. If the ARDEX MC ULTRA Moisture Control System is used, no additional priming is needed. The sand-broadcast surface of the ARDEX MC ULTRA is the primer. 2. Follow manufacturer installation instructions for primer suitable for substrate conditions ARDEX PC-M INSTALLATION A. After mixing, apply a scratch coat of ARDEX PC-M to the substrate with the flat side of a steel trowel to obtain a solid mechanical bond. Apply sufficient pressure to fill all defects and to feather the product onto the subfloor surface. B. It is necessary to install a minimum of 3 coats of the ARDEX PC-M to a total thickness not to exceed 1/16 (1.5 mm). C. Since ARDEX PC-M is a micro-topping, it is common to have trowel marks and variations in surface finish. Variations in surface texture will be highlighted when the PC-M surface is polished. D. Allow the ARDEX PC-M to cure a minimum of 16 hours before proceeding with the micro-polishing process. SECTION MODIFIED 02/08/12

7 3.05 MICRO-POLISH PROCESS A. Application 3.06 EDGES 1. After ARDEX PC-M has sufficiently cured apply ARDEX PC 10 Lithium Densifier for ARDEX Polished Concrete Toppings. 2. MICROPOLISH/BURNISH #1: FLOR-GRIT 800 Diamond Impregnated Pad. 3. MICROPOLISH/BURNISH #2: FLOR-GRIT 1500 Diamond Impregnated Pad. 4. MICROPOLISH/BURNISH #3: FLOR-GRIT 3000 Diamond Impregnated Pad. 5. Dry mop the floor clean to remove all debris. 6. Apply ARDEX PC FINISH or DIAMTIC FLOR-FINISH Stain and Wear Protection Treatment, per application instructions at a rate of 2,000 square feet per gallon. 7. Allow to dry a minimum of 15 minutes. 8. MICROPOLISH/BURNISH #4: FLOR-GRIT 3000 Diamond Impregnated Pad 9. Dry mop the floor clean to remove all debris. 10. Apply ARDEX PC FINISH or DIAMATIC FLOR-FINISH, per application instructions at a rate of 2,500 square feet per gallon. 11. Allow to dry a minimum of 15 minutes. 12. MICROPOLISH/BURNISH #5: FLOR-GRIT 3000 Diamond Impregnated Pad A. Where desired, polished edge work of ARDEX PC-M shall be done with a 5 DIAMATIC Hand Held or Walk Behind polishing tool. The edge polishing process will match the corresponding steps outlined above for the desired gloss level, and each edge polishing step shall be done immediately after the matching main polishing step PROTECTION A. Prevent any spills or stains from coming into contact with the floor. Clean any spills that may occur as quickly as possible. B. Avoid moisture for 72 hours after installation. Don t permit standing water for this period or place any protective plastic sheeting, rubber matting, rugs or furniture that can prevent proper drying, thereby trapping moisture, which can result in a cloudy effect on the floor. C. Light pedestrian use only in the 24 hours after installation. Normal traffic recommended 14 days after completion of the ULTRAFLOR POLISHED Concrete System. SECTION MODIFIED 02/08/12

8 D. Protect the finished ULTRAFLOR Polished Concrete System from continuing construction and build out as needed by installing material such as the DIAMATIC PRIMO-COVER Protective Floor Covering or DIAMATIC ECONO-COVER Protective Floor Covering ONGOING MAINTENANCE A. IMPORTANT NOTICE: Maintaining the ULTRAFLOR Polished Concrete System and adherence to a recommended cleaning schedule will help the floor hold its gloss longer and greatly reduce the absorption of spilled liquids. The treated concrete floor is easily maintained by regular cleaning with the Maintenance/Post Cleaning procedure, accompanied by Micro-Polishing. B. Newly Installed ULTRAFLOR Polished Concrete System 1. Restrict water cleaning for 72 hours after installation. Use only a dry mop to clean. Avoid putting mats or covering treated surface to allow coating to fully cure out. 2. DO NOT USE cleaners that are acidic or that have citrus (de-limonene) or Butyl compounds. Although the ULTRAFLOR Polished Concrete System is chemical and stain resistant, the application of these high acid cleaners may etch the surface and cause a residual stain. Regular maintenance and cleaning will help prolong surface shine. C. Daily Maintenance and Cleaning 1. Once the system is fully cured out (min. 72 hours), routinely sweep, dry mop and wash with neutral ph cleaners or water using a mechanical auto scrubber with vacuum to pick up any residual standing water. 2. DO NOT USE cleaners that are acidic or that have citrus (de-limonene) or Butyl compounds. Although the ULTRAFLOR Polished Concrete System is chemical and stain resistant, the application of these high acid cleaners may etch the surface and cause a residual stain. Regular maintenance and cleaning will help prolong surface shine. D. Bi-Monthly or Monthly Cleaning (dependent upon floor wear and traffic) 1. Follow the daily maintenance process. 2. Apply DIAMATIC FLOR-MAINTAINER diluted with 2 parts water using a DIAMATIC CONDOR APPLICATOR or microfiber pad at a coverage rate of 8,000 to 10,000 square feet (743 to 929 m 2 ) gallon. 3. Burnish/Micro Polish with DIAMATIC FLOR-GRIT 3000 Diamond Impregnated Pad. 4. Dry mop to remove any debris. SECTION MODIFIED 02/08/12

Although the ULTRAFLOR Polished Concrete System is chemical and stain resistant, the application of these high acid cleaners may etch the surface and cause a residual stain. Regular maintenance and cleaning will help prolong surface shine. E. ULTRAFLOR Rejuvenation (recommended application every 1 to 2 years depending upon floor wear and traffic) 1. Follow the daily maintenance process. 2. Application of ARDEX PC FINISH or DIAMATIC FLOR-FINISH applied with Condor applicator or microfiber pads. Follow manufacturer application instructions. 3. Burnish/Micro Polish with DIAMATIC FLOR-GRIT 3000 Diamond Impregnated Pad. 4. Dry mop to remove any debris. 5. DO NOT USE cleaners that are acidic or that have citrus (de-limonene) or Butyl compounds. Although the ULTRAFLOR Polished Concrete System is chemical and stain resistant, the application of these high acid cleaners may etch the surface and cause a residual stain. Regular maintenance and cleaning will help prolong surface shine. SECTION MODIFIED 02/08/12
