PRELIMINARY FLOOR INSPECTIONS CHECK THE SUBSTRATE: Determine finish on existing substrate. All conventional finishes must be removed. Ultradurable urethanes and previous coats of Eco-UVC may be sanded and recoated or removed based on customer need. If coating concrete, it must be structurally sound and free of curing membrane, paint or other sealer. If you suspect that the concrete has been previously sealed, call Tennant Company, technical support for further instructions. CHECK FOR MOISTURE: Check existing covering for visible signs of moisture. If none present, substrate may be coated. Concrete must be dry before application of this floor coating material. Concrete moisture testing must occur. Calcium chloride testing or in-situ relative humidity testing is recommended. Readings must be below 3 pounds per 1,000 square feet (1.5 kg per 150m 2 ) over a 24-hour period on the calcium chloride test or below 75% relative internal concrete humidity. Test methods can be purchased at see ASTM F1869 or F2170, respectively or follow manufacturer's instructions. NOTE: Although testing is critical, it is not a guarantee against future problems. This is especially true if there is no vapor barrier or the vapor barrier is not functioning properly and/or you suspect you may have concrete contamination from oils, chemical spills or excessive salts. CHECK THE TEMPERATURE AND HUMIDITY: Floor temperature and materials should be between 65 F (18 C) and 90 F (32 C). Humidity must be less than 80%. DO NOT coat unless floor temperature is more than five degrees over the dew point. SAFETY (See machine manual.) Wear eye protection with side shields and gloves for protection during mixing. Curing is accomplished by using UV light. In order to limit exposure to skin and eyes, long pants, closed toe shoes and eye protection rated for 100% UV protection should be worn during the cure process. APPLICATION EQUIPMENT Slow-speed power drill (500 rpm or less) Jiffy Mixer Blade Pro-style paint roller assembly that provides support on both ends of the roller Shed-resistant 3/8 (10 mm) nap rollers (wire brush and thoroughly tape to remove all loose fibers) 6 (182.9 cm) threaded handles 2 (50.8 mm) safe-release painters tape for thresholds, transition strips and for laying out stop points if you are rolling and curing a larger area in sections 2 (50.8 mm) and 4 (101.6 mm) brushes and foam rollers for cutting in edges and small detail areas 4 (101.6 mm) scrapers to remove wax residue from edges and any drips that set during application A box of shop rags and lint-free cotton rags Microfiber tack rag (untreated) Eco-UVC Tennant Company 08/04/09 Page 2 of 6

3 Wooster Wide Boy paint bucket with long side of cover cut back 5 (127 mm) (just enough space to insert roller to load). NOTE: If a deep, covered tray is not used, coating will cure in mass before it is applied. Black contractor grade garbage bags Duct tape that adheres well to VCT Poly to protect adjacent areas from stripping solution and for mixing station Black poly to cover any windows during daylight Extension cord at least 14/3 and no longer than 50 (15.24 m) (to total no more than 100 (30.48 m) when added to the 50 (15.24 m) cord attached to machine) Safety Glasses rated for 100% UV protection An InstaCure+ machine with side shields set 0.25 (6.35 mm) (12.7 mm) off ground (make sure all bulbs light) UV hand-held curing unit for hard-to-reach areas. The unit pictured is model UVH-255 from Panacol-Elosol. Turn off these lights. If there is not adequate ambient light for application, use temporary job lights. If the ambient bulbs cannot be determined, after the coating is mixed and prior to edging, use a small amount of material (cover the rest in the can) to do a work time field test under the lights on a small area or piece of cardboard. An edging roller can be used; material should reroll for at least 20 minutes. 3. Use a measuring wheel or laser rangefinder to measure the square footage of all areas to be coated. 4. Ensure you have material to achieve a minimum coverage rate of 500 square feet (12.3 m 2 /L) per gallon (3.78 litres). 5. Plan your curing process to ensure that outlets are within reach. There is a re-start delay each time the machine is unplugged. DO NOT change outlets in the middle of curing an area. 6. Roll unplugged machine over areas of concern, checking for elevation changes like ramps or uneven floors. Do this before coating, to ensure machine does not drag or hit floor. 7. Practice, if necessary, rate of cure (pace) (0.5 miles ( m) per hour = 0.75 ft (228.6 mm) per second) and how to handle the extension cord during curing. Make sure it never touches any uncured part of the floor. 8. Determine ahead of time if the hand-held unit will be required so it is warmed up and ready to go when needed. 9. Tape off logical sections of the floor if you plan to roll and cure it in sections. Use tile lines, transition strips, and other logical sight lines for masking guides. PLAN Plan each installation carefully before coating. Each jobsite will have unique situations to consider. 1. If coating during the daytime, have enough black poly to cover windows and doors in the area to be coated. Remember, Eco-UVC is cured with ultraviolet light and exposure to daylight can cause the product to cure as it is being applied. Always eliminate UV light in the area to be coated by blocking windows and doors. 2. Metal halide light bulbs will also affect cure of the coating. PREPARATION Sweep, detergent scrub and rinse with clean water to remove surface dirt, grease, oil and contaminants. For bare concrete floors: 1. Acid etch 2. Detergent scrub OR 1. Diamond grind the floor with fine diamonds 2. Sweep and vacuum to remove loose debris For VCT and other surfaces with conventional finish: 1. Protect adjacent areas with well adhered duct tape and plastic. 2. Strip all of the old finish. Be sure to completely remove all of the old material and follow the proper recommended stripping technique. There should be no sticky residue on floor. Eco-UVC Tennant Company 08/04/09 Page 3 of 6

4 3. Wet sand all areas of the floor to be coated in order to control dust. Use a swing buffer with 100 grit screens. Use a palm sander for the edges and detail areas. Completely sweep and scrub the area to remove the sanding dust. 4. Since auto scrubbers with dirty tanks, squeegees and wheels can transfer contaminants to the floor, visually inspect before using. Clean if necessary. Detergent scrub, clean water rinse the floor and allow it to dry. Make sure that small channels and gaps in tiles or floor sections are completely clean and dry before applying Eco-UVC coating. 5. After the floor is dry, tack entire surface repeatedly using a damp, lint-free, microfiber towel to remove fine dust/debris. Check for dust by wiping your hand over the floor. Tack again if necessary. NOTE: Microfiber that leaves a residue behind must not be used. 3. Start rolling out the main floor in small 8 x 8 (2.44 m x 2.44 m) sections by dipping the roller and rolling off any excess material in your pan. 4. Start in the center of an 8 x 8 (2.44 m x 2.44 m) area and evenly roll out two paths - left to right and right to left. 5. Then, dip the roller, roll off any excess and roll out two more paths - left to right and right to left. 6. Once you have completely applied Eco-UVC left to right in your 8 x 8 (2.44 m x 2.44 m) work area, use long front to back rolling strokes in the area, smoothing out the product, making sure there are no missed spots and coverage is even. 7. Finally finish roll that area by rolling all the way straight in and out, picking up the roller, moving over and rolling straight in and out. Continue until the entire 8 x 8 (2.44 m x 2.44 m) area is finished, then move on to another 8 x 8 (2.44 m x 2.44 m) section. 8. Be sure to remove all of your masking tape as you are rolling. Once you have rolled past the masking tape, you may not be able to get back to it until after the floor is cured. The masking tape will then be cured into your work. SETUP 1. Clear an area to be used as a mixing station, adjacent to the floor that will be coated. Lay down a sheet of poly about 8 x 8 (2.44 m x 2.44 m), tape the edges down and then cover it with a layer of paper. This will protect the floor in the mixing area from spills and drips. 2. Mask off all borders where you do not want coating applied. 3. Lay out your application tools. 4. Brush and tape the roller covers to remove and reduce any roller lint that may be left on the floor. MIX Follow mixing instructions carefully for Eco-UVC: 1. Mix only as much Eco-UVC as you can use in 20 minutes. 2. Shake part B. 3. Open Part A and premix with the Jiffy mixer. Mix for 1 minute to ensure Part A is properly blended. 4. Add part B to part A, and mix for three more minutes. 5. Pour small amount of material into edging containers. Leave the balance of the material in covered can. 6. Once adequate area has been cut in, immediately pour mixed material in the covered Wooster Wide Boy paint bucket. Eco-UVC is now ready for application. APPLICATION 1. Always keep your supply of mixed Eco-UVC as close to you as possible in order to reduce the possibility of drips. Be careful not to let the product drip onto the floor. If product drips onto the floor, roll out any drips immediately. 2. Cut in the floor edges with brushes and roll with a foam roller. 9. It is important to keep track of your coverage rate. Be certain that you are covering a minimum of 500 square feet (12.3 m 2 /L) per gallon (3.78 litres). NOTE: If material is applied too thick, surface defects may be seen and poor adhesion may result. CURE 1. Allow at least 8 minutes after applying before starting to cure. This gives the product time to level out, reducing any orange peel texture left from the roller application. 2. While the coating is relaxing, stage the InstaCure+ machine in an area far enough away from the wet floor so it doesn t cure any of the coating. Before plugging the machine in, make sure everyone in the curing area is wearing approved UV eye protection. Plug the machine in and allow it to warm up for 3 minutes. Be sure to move the machine around during warm-up so the UV light doesn t damage the flooring underneath. 3. It is best to start curing by using an assistant to manage the extension cord while another person handles the InstaCure+ machine. 4. Turn on the sidelight which overhangs the leading edge, or wet side of the curing machine. Start curing by pushing the machine in front of you at a slow walking speed (0.5 miles ( m) per hour = 0.75 ft (228.6 mm) per second). Use walls and sight lines to create straight curing paths and work all the way up to walls and edges. Eco-UVC Tennant Company 08/04/09 Page 4 of 6

5 5. When you reach a wall, pause for 3 seconds before pulling the machine back. Always be careful to keep the wheels and extension cord from coming into contact with the uncured parts of the floor. 6. Follow your plan for special areas and elevation changes. It is OK to overlap each curing path. This insures that the entire area is getting cured. Be sure to go all the way around columns. If necessary, use the handheld curing unit for hard-to-reach spots. You only need to go over the floor once. One coat of Eco-UVC and one curing pass makes the floor ready for use. When the floor is completely cured, clean up the mixing area, dispose of all waste properly and take down any light blocking plastic and tape you may have needed. MAINTENANCE Proper maintenance will increase the life and help maintain the appearance of Eco-UVC floor coating. 1. Sweep and scrub regularly as dirt and dust are abrasive and can quickly dull the surface of the coating. 2. Use soft nylon brushes or white pads on an auto scrubber. 3. Use Tennant ec-h2o as an alternative to detergent. 4. Remove spills quickly as certain chemicals may stain and could permanently damage the coating. 5. Avoid scratching or gouging the surface. All floor finishes and coatings will scratch if heavy and/or sharp objects are dragged across the surface. REPAIR 1. Detergent scrub and rinse with clean water to remove surface dirt, grease, oil and contaminants. 2. Tape around the damaged area with 2 (50.8 mm) masking tape. Tape right on VCT grout lines in order to hide the edge of the repair. 3. Sand all areas of the floor to be coated. Use a swing buffer to abrade flooring, using 120 grit screens or sand paper. Wet sand with screens if dust control is a concern. Use a palm sander for smaller areas. Completely sweep and scrub the area to remove the sanding dust. 4. Pull tape. 5. Detergent scrub and clean water rinse the floor and allow it to dry. Make sure that small channels and gaps in tiles or floor sections are completely dry before applying Eco-UVC coating. 6. Retape around the damaged area with 2 (50.8 mm) masking tape. Tape right on VCT grout lines in order to hide the edge of the repair. Push the tape down in order to prevent wet material from wicking under the tape. 7. After the floor is dry, Tack rag entire surface using microfiber materials. Check for dust by wiping your hand over the floor. Tack rag again if necessary. 8. Follow instructions under SETUP, MIX, APPLICATION and CURE. 9. Stripping Eco-UVC is not part of the standard lifecycle of the InstaCure+ system. Removal may be needed if preparation was not adequate or if severe damage cannot be sanded out. NOTE: Mechanical removal on tile that is not colored all the way through is not recommended as inconsistent color will be the result. If removal is required, use 140 grit diamond tools specifically designed for this purpose on a Tennant scrubber or swing buffer. Perform removal using a cross hatch pattern (north south, then east west). Use multiple passes to remove the coating by cutting it off of the floor. Periodically clean area to check removal progress to prevent tile damage. Once the coating is removed, use 120 grit sandpaper to smooth the surface for application of finish. Scrub and rinse with clean water and allow it to dry. REAPPLICATION Follow instructions under REPAIR to recoat an entire area when multiple fine scratches have reduced the gloss level of the floor to a point where the appearance of the floor is not acceptable. TRANSPORT OF INSTACURE+MACHINE The light head assembly can be easily removed for transporting the Instacure+ machine. (See machine manual.) The packing crate that the machine is originally shipped in is made of heavy grade cardboard that can be reused many times. This carton will help to protect the machine from damage caused by collisions with unsecured equipment.

6 MAINTENANCE GUIDELINES Allow floor coating to cure at least one week before cleaning by mechanical means (e.g., sweeper, scrubber, disc machine). Care: Proper maintenance will increase the life and help maintain the appearance of your new Tennant floor coating. Sweep and scrub your new coating regularly, as dirt and dust are abrasive and can quickly dull the finish, decreasing the life of your coating. Remove spills quickly as certain chemicals may stain and could possibly permanently damage the finish. Use soft nylon brushes or white pads on your new floor coating. Polypropylene or abrasive bristle (Tynex ) brushes can cause premature loss of gloss. Detergent: Tennant has a full range of detergents--general purpose to heavy duty--for your cleaning needs. For assistance in determining which detergent is right for your facility or for additional technical information call: US ( Aust). Caution: Avoid scratching or gouging the surface. All floor coatings will scratch if heavy objects are dragged across the surface. Do not drop heavy or pointed items on the floor as this may causing chipping or concrete popouts in the case of a weak cap. Rubber tires can permanently stain the floor coating from plasticizer migration. Plexiglass between the tire and the floor coating can prevent discoloration. Rubber burns from quick stops and starts can heat the coating to its softening temperature, causing permanent marking. Repair: Repair gouges or scratches or chip outs as soon as possible to prevent moisture or chemical contamination.
