2100 Series ProFloor® Epoxy |

|||||||||||||||||||||||||||||||||
| Surface Preparation | |||||||||||||||||||||||||||||||||
| New Concrete: | |||||||||||||||||||||||||||||||||
| New concrete should be at least 30 days old, had a light steel trowel finish and have a vapor barrier under the slab. Remove any curing compounds. Repair cracks with Pro Guard's Epoxy Crack repair products. Products for repairing cracks in Masonry and Crack Repair Instructions. | |||||||||||||||||||||||||||||||||
| Existing Concrete: | |||||||||||||||||||||||||||||||||
| Remove any existing coatings using a rotary grinder (available at most Equipment Rental Stores) Vacuum dust. Repair cracks and surface defects using Epoxy repair products, see Crack Repair Instructions. Remove oil stains using a combination of solvent wiping (you must allow the solvent to completely evaporate) followed by heating with a small propane torch to oxidize any remaining oil. | |||||||||||||||||||||||||||||||||
| Surface Profile: | |||||||||||||||||||||||||||||||||
| The surface prep method used whether rotary grinder, shot blast or sanding should produce a minimum surface profile of 4-6 mils in order to achieve adequate adhesion of the epoxy coating. | |||||||||||||||||||||||||||||||||
| Chemical Resistance: | |||||||||||||||||||||||||||||||||
| The 2100 Series Floor Epoxies using the F2201 Standard Hardener have very good resistance to commonly used floor cleaners, oils, anti freeze, hydraulic fluids and solvents. The F2202 Chemical Resistant Hardener expands the resistance properties to include dilute acids and corrosive compounds. | |||||||||||||||||||||||||||||||||
| Moisture: | |||||||||||||||||||||||||||||||||
| On grade and below grade installations are prone to moisture transmission problems. An ASTM D-4263 moisture test or the Calcium Crystal moisture absorption test should be performed prior to coating these floors. | |||||||||||||||||||||||||||||||||
| Mixing: | |||||||||||||||||||||||||||||||||
| The mix ratio for all 2100 Series Epoxies is two volumes Part A to one volume Part B. This ratio is the same for Standard as well as Chemical Resistant Hardeners. Mix Part A and Part B individually first then combine together and mix thoroughly using a drill mixer for 2-3 minutes. Scrape sides of container occasionally to incorporate all material. Any air being incorporated will release when applied to the floor. | |||||||||||||||||||||||||||||||||
| Cure Conditions: | |||||||||||||||||||||||||||||||||
| Floor and air temperature must be at least 60° F and relative humidity preferably below 85%. Floor temp must be above the dew point. The coating will substantially cure in 8-12 hours and can take light foot traffic in 24 hours. | |||||||||||||||||||||||||||||||||
| Pot Life: | |||||||||||||||||||||||||||||||||
| Pot life will vary from 45 min. to 1 hour at 80°F and below. The amount of material mixed at one time will also affect pot life. Larger quantity mixes build up heat faster and shorten pot life. Working time is increased when material is spread on floor where the generated heat can readily dissipate. | |||||||||||||||||||||||||||||||||
| Recoatability: | |||||||||||||||||||||||||||||||||
| The 2100 Series Epoxies can be recoated within 36 hours using another epoxy or a Urethane coating. When cure has exceeded 36 hours the surface must be sanded before recoating. | |||||||||||||||||||||||||||||||||
