SEALS & PROTECTS Waterproof, chemically resistant membrane protects substrates from freeze-thaw spalling. Stops further corrosion of reinforcing steel. FAST REPAIR & CURE Liquid becomes solid in 60 seconds. Traffic Ready in 10 minutes. SAFE TO USE No toxic fumes during application. NO ODOR. YEAR ROUND USE Make repairs, resurface pavements, and apply protective coating in freezing weather or in the heat of summer. 10-Minute Traffic Ready for Machine Applied Version. 30 – 90 Minute Traffic Ready for Hand-Mix Version, Cure time dependent upon temperature and application technique chosen. USAGE Super Fast-Setting; simplified application equipment, FASTCAT®, siphons the nearly water-thin liquids (“A” and “B”) from their respective containers through separate hoses and mixes them in a mixing nozzle just prior to application. The mixed liquid is flooded or sprayed over graded aggregates, poured into cracks, or sprayed onto wood, steel or concrete decks, solidifying in one minute. The mixed liquid cures to a resilient, impact resistant solid plastic, suitable for repairing and sealing spalls, potholes, cracks and expansion joint headers. Repairs can be made to smoothly transition mismatching grades with adjacent slabs. Hand-mix versions are available. Traffic Ready in 10 minutes. LIMITATIONS Apply only to properly cleaned and prepared surfaces. Do NOT apply to wet, dirty, greasy, scaling or waxed surfaces. Consult LiquidConcrete technical department for approved surface preparation methods and application techniques. Read Material Safety Data Sheets and Installation Instructions before using.

Cracks greater than 1/6 inch in width shall be routed to a minimum of 1/4 inch wide by 1/4 inch deep and filled with URE-KOTE R-60 or URE-KOTE PF-60 materials. 3. Fill all expansion joints as required – using UREKOTE PF-60. 4. All application equipment shall be in good operating condition. 5. Coating materials shall not be applied when the ambient air temperature or the surface temperature is outside the boundaries as stated on the product data sheets and application guidelines. 6. Keep material out of sun or hot areas prior to applying, as this may cause working time to be diminished and could cause poor appearance and/or adhesion. If room and or concrete surface is hot (85 deg F or more) you can spray with cool water and soak for a short period to cool surface. 7. Vacuum the surface free of water, and torch dry if necessary, prior to applying product. Damp surfaces must be thoroughly dried prior to the application of product. This step is essential for proper cure, adhesion, and postcure performance. 8. Product shall be maintained at 50℉ – 80℉. 9. Product may be installed between 20℉ 100℉. For temperatures above or below these limits please consult LiquidConcrete. SURFACE PREPARATION 1. Prepare surface to a minimum CSP-3 profile, removing all surface contaminants, including sealers, oils, or other bond inhibiting substances. Mechanically abrade by shotblaster, scarifier, bushing hammer, scabbler or other means to provide a coarse (rough) texture. 2. For overlays, cut keyway channel (groove) using concrete saw equipped with dry cut diamond blade around perimeter of area to be resurfaced. Keyway channel (groove) depth shall be a minimum of ½” depth. Surfaces adjacent to a vertical plane (such as curbs, walls, tanks, etc.) shall have keyway channels cut approximately 4 – 6 inches INSTALLATION GUIDELINES PRE-INSTALLATION CHECKLIST 1. All substrates shall be sound, solid and free from any loose or failing components. All surfaces must be free from previously applied coatings, dust, rust, scale, grease, oil, and other bond breaking contaminants. Page 2 of 4 PRODUCT DATA SHEET Product: URE-KOTE PF-60 Version: May 21, 2007 back from vertical plane towards the interior of area to be resurfaced. Keyway channel shall be ½” deep by ½” wide. 3. For overlays, chip 2 inch wide taper back from interior edge of keyway channel at all termination edges (ie: drains, doors etc.). Using bush hammer or chipping gun equipped with a 1 – 2 inch wide spade blade, chip a 2” wide taper back from edge of interior keyway channel (groove) inward towards the area being resurfaced. Taper shall match depth of keyway channel at its deepest point, which is the edge of the keyway, and taper out to 0” at its most shallow point, 2” inches towards the interior of the area to be resurfaced. 4. Rout out all cracks to a minimum of ½” wide by ½” deep, using concrete saw equipped with dry cut crack chasing blade. 5. Vacuum surface free of all dust and dirt. MIXING AND INSTALLATION INSTRUCTIONS NOTE: Mix ratio is 1:1 by volume. For machine applied (FastCat) product refer to your FastCat operators manual and consult your LiquidConcrete representative for specifics. HAND MIX INSTRUCTIONS Before Beginning - Read Entire Document Mix a small sample before working on your specific project so you will know what to expect as to what product looks like while setting and curing. Following directions below, mix a small amount of material for a test. Remember that as material quantities increase, the heat generated by the product increases, and the potlife of mixed product will decrease respectively. FOR RESIN ONLY REPAIRS - (control joints, non-skid overlays, cable/conduit applications, large potholes, random crack repair, etc.) 1. Measure equal parts URE-KOTE PF-60 separately (equal parts A & B)…DO NOT BLEND TOGETHER YET!!! Set aside. STOP! - BEFORE BEGINNING NEXT STEP MAKE SURE ALL MATERIALS ARE READY FOR MIXING & IMMEDIATE INSTALLATION. MATERIALS CURE VERY QUICKLY. DO NOT PERFORM THE NEXT STEP (#2) UNTIL YOU ARE READY TO IMMEDIATELY FOLLOW UP WITH STEPS #2 thru #3. 2. NOW, using pre-measured PF-60 (from STEP #1) mix PF-60 A&B together, stirring for 30 seconds (scraping side walls of mixing container). 3. Pour into or onto application area. For non-skid overlay (a) Pour mixture into ribbons on surface and spread with ⅜” nap roller. (b) Broadcast specified aggregate. (c) Apply second coat of PF-60 to lock in aggregate. For Pothole Repair and Random Crack Repair (a) Place aggregate in pothole or crack slightly below grade (⅛” below). (b) Pour PF-60 onto aggregate. (c) Top with specified topping aggregate. For Joint Filling (a) Pour PF-60 into joint. (b) IF OVERFILLED - scrape off excess with sharp floor scraper. FOR SAND-FILLED/MORTAR REPAIRS - (Shallow chips/spalls, vertical repairs, small potholes, patching, etc.). These repairs require priming with resin only PF-60. SAND - You will need about 40 lbs of #16 silica sand per gallon depending on how wet or dry the finished mix needs to be. Make sure clean, dry, fine-grade approved aggregate is open and ready for use. Set aside (see Step #5). Prepare 2 batches of resin only PF-60. One for the sand-filled application and one smaller batch for priming. 1. Measure equal parts URE-KOTE PF-60 separately (equal parts A & B). Example: 4 oz. each A and B for use as primer batch. Then 16 oz. each A and B to mix with sand for Mortar/Grout product. DO NOT BLEND TOGETHER YET!!! Set aside.

MATERIALS CURE VERY QUICKLY. DO NOT PERFORM THE NEXT STEP (#2) UNTIL YOU ARE READY TO IMMEDIATELY FOLLOW UP WITH STEPS #2 thru #6. 2. NOW, using pre-measured PF-60 for use as primer (from STEP #1) Mix PF-60 A&B together, stirring for 30 seconds (scraping side walls of mixing container). 3. Prime prepared concrete substrate with mixed PF-60 (use paint “chip” brush to coat substrate with PF-60). 4. While worker is priming repair areas with primer batch, second worker mixes PF-60 A&B for use as the Mortar/Grout batch together, stirring for 30 seconds (scraping side walls of mixing container). 5. Add SAND to PF-60 and blend to saturation. NOTE: Adding more SAND to PF-60 will create a drier mix. Adding less will make the mix “wetter” and more pourable. Make sure PF60 as primer is still wet on the repair area when applying the PF-60 “grout”. 6. Top with traction aggregate.
