Application Coverage
Coverage Rate, ft2/gal [m2/L]) 53-535 [1.3-13.1]Application Thickness, wet mils [mm] 3-30 [0.08-0.76] - Limitations
Orange Peel: Eco-UVE with fumed silica can be used as a topcoat to achieve a textured appearance.
Colors: Multiple coats may be needed to achieve complete hide in lighter systems.
UV/Light Stability: This is an epoxy product with improved UV resistance, but it may amber/yellow over time.
Thickness: The clear, thickened version of Eco-UVE with fumed silica will "ghost" or will appear cloudy if applied at >8 mils per coat.
Contamination (Fisheyes): Products may fisheye if oil, silicones, mold release agents or other contaminants are present.- Application Equipment
- Protective clothing
- Jiffy® mixer blade [Tennant Part No. 08643-1 (1 gal) or 08643-5 (5 gal)]
- Slow speed drill (500 rpm or less)
- 18-24" Flat rubber squeegee
- 18-24” Notched rubber squeegee
- Roller assembly (18")
- Medium (3/8") nap roller (shed resistant)
- Spiked shoes
- 60 grit sandpaper
- 80 grit sandpaper
- 100 grit sandpaper
Assemble Equipment: Due to the limited pot life of the material, all application equipment, etc. should be ready for immediate use. (Clean roller with tape to remove any residual lint.)
- Preparation
Ensure concrete is free of dirt, grease, oil or other contaminants. Certain types of contaminant may interfere with coating adhesion and cause fisheyes or defect in the coating. Scrub with detergent, rinse with clean water, and allow to fully dry.
Concrete Preparation Options for Thin to Medium Film Applications (25 mils (0.63 mm) maximum)
Diamond Grind: (results of diamond grinding may vary depending on technique and the hardness of the concrete. Additional mils may be required). Sweep to remove large debris and vacuum to remove fine dust.
Light Blast: Use magnetic broom to remove excess shot, sweep to remove large debris and vacuum to remove fine dust.
Concrete Preparation options for Thick-Film Applications
Steel Shot Blast: Use magnetic broom to remove excess shot, sweep to remove large debris and vacuum to remove fine dust.
Scarify: Sweep to remove large debris and vacuum to remove fine dust.
Filling Joints: Depending on the preference of the facility owner, joints may or may not be filled. If the joints are filled, non-moving joints, i.e. contraction or control joints, can be hard filled with thickened epoxy or with a semi-rigid joint filler such as Eco-PJF™ or Eco-EJF™. Construction joints less than one inch wide may also be filled with Eco-PJF. Isolation or expansion joints must be filled with a flexible material designed for this purpose. Coating applied over filled joints may crack if there is concrete movement.- Application - Primer Coat
A primer coat is needed when using Eco-UVE as part of an epoxy system. A thin coat of Eco-UVE may be used as a primer to wet out concrete, help seal off concrete pores and minimize outgassing bubbles. Apply a tight coat of primer with a clean, flexible squeegee. Backrolling is not recommended. There should be no mil build over the high spots of the concrete.
COVERAGE RATE will depend upon coating thickness. Much of this will soak into porous concrete. One gallon (3.78 liters) of Eco-UVE will cover:- 535 ft2 (49.70 m2) @ 3 mils (0.08 mm) wet/dry film
- 400 ft2 (37.16 m2) @ 4 mils (0.10 mm) wet/dry film
- 321 ft2 (29.82 m2) @ 5 mils (0.13 mm) wet/dry film
PREMIX PART A using a Jiffy mixer blade and slow speed drill. Pour out 2 gallons (7.56 liters) into a measuring container. Then, pour the measured Part A into a mixing pail.
COLORS: Premix Tennant Colorants to ensure uniform color. Colorant is added to the Part A and mixed using a Jiffy® mixer blade and slow speed drill. NOTE: When using colorant in the bulk units, add the colorant to the Part A that has been measured into the "mixing pail".
ADD ECO-UVE PART B TO PART A (3 GALLONS / 11.34 LITRES TOTAL MIX). Pour out 1 gallon (3.78 liters) Part B into a measuring container that is separate from the one used with the Part A. Then, add the measured Part B to the Part A already in the mixing pail. POTLIFE: Mix only enough material which can be applied within the work time (time between the addition of Part B to Part A and the completion of all application actions). Check the following chart for work times at various temperatures. For smaller quantities, use 2 parts PART A to 1 part PART B by volume.

50 40 35 30 25
MIX FOR 2 MINUTES using a Jiffy® mixer blade and slow speed drill. (Failure to do so could result in lower/diminished coating properties.)
IMMEDIATELY POUR ALL OF THE MIXED MATERIAL onto the floor in a single bead.
PUSH THE FLAT SQUEEGEE at an even speed with sufficient down pressure to apply the thinnest coat.
START THE SECOND AND REMAINING PASSES by pushing material parallel to the first stroke. Hold the bead of material near the center of the bar. NOTE: Eco-UVE applied thin may "bridge" holes and cracks momentarily before soaking in--make sure the previously squeegeed area is overlapped (halfway). NOTE: The use of spiked shoes will allow freedom of movement on the wet floor.
TO REDUCE OUTGASSING BUBBLES, it is best to wait until the primer has set up enough to walk on before applying a build coat of Eco-UVE. The primer does not need to be sanded if coated within 24 hours at floor temperatures 65°F-90°F (18°C-32°C).
If primer is not coated within 24 hours, it must be sanded with 60 grit paper. We recommend thorough sanding with a swing-type buffer so that multiple scratch marks cause an obvious gloss loss on all areas (depressions will remain shiny), and the floor is uniformly dulled. The ability to see individual scratch marks is an indication that sanding is not adequate. Scrub with detergent and rinse with clean water before coating.- Application – Build Coat (If Required)
COVERAGE RATE will depend upon required thickness. One gallon (3.78 liters) of Eco-UVE will cover:
- 160 ft2 (14.86 m2) @ 10 mils (0.25 mm) wet/dry film
- 107 ft2 ( 9.94 m2) @ 15 mils (0.38 mm) wet/dry film
- 80 ft2 ( 7.43 m2) @ 20 mils (0.51 mm) wet/dry film
NOTE: Total Eco-UVE (prime and build coat) should not exceed 35 mils (0.89 mm).
REPEAT STEPS used for mixing and spreading of the primer coat. A notched squeegee can be used to increase the thickness applied.- *1/16" (1.59 mm) notched squeegee to apply 10-15 mils (0.25-0.38 mm)
- *1/8" (3.18 mm) notched squeegee to apply 15-20 mils (0.38-0.51 mm)
- *1/4" (6.35 mm) notched squeegee to apply more than 20 mils (0.51 mm)
- *These guidelines were arrived at by using new squeegees on smooth concrete with little applied pressure. The application rate is affected by worn squeegees, applied pressure and texture of the concrete.
Immediately after the Eco-UVE is applied and there is room to roll, a second person will BACKROLL THE MATERIAL with a 3/8” roller to a smooth and uniform appearance. NOTE: Get off the Eco-UVE as soon as possible.
ALLOW COATING TO CURE 24 hours at 75°F (24°C) before opening to light traffic. Allow more time at low temperatures or for heavier traffic. Full coating properties take 14 days to develop.- Optional Application Of Orange Peel Texture

If Eco-UVE is being topcoated with a Tennant urethane except Eco-HPS® 100 at floor temperatures of 65-90°F (18-32°C), it does not need to be sanded if applied within 24 hours. NOTE: This is a Tennant solution only, DO NOT try this with competitive epoxies.
- Sanding Required
Eco-UVE must be thoroughly sanded if applying Eco-HPS 100 (see chart below).
APPROXIMATE SAND TIME (hours) - °F (°C): 65 (18.3) 70 (21.1) 75 (23.9) 80 (26.7) 90 (32.2)

Eco-UVE must also be sanded if applying other Tennant urethanes after 24 hours. Use 80 grit sandpaper except for Eco-HPS 100, WearGuard™-240 Gloss and Tennant CRU–use 100 grit sandpaper. The use of more aggressive paper will introduce deep grooves that will not be covered by a single, thin coat of urethane; swirl marks will be particularly evident if the topcoat is glossy. We recommend thorough sanding with a swing-type buffer so that multiple scratch marks cause an obvious gloss loss on all areas (depressions will remain shiny), and the floor is uniformly dulled. The ability to see individual scratch marks is an indication that sanding is not adequate. Scrub with detergent and rinse with clean water before coating and tack rag to remove fine dust.

Safety & Health
- Environmentally & User Friendly
- Excellent UV resistance
- Seals concrete, protecting against dirt and spills
- Cleans easily, saving detergent, labor and water
- Preliminary Floor Inspections
CHECK THE CONCRETE: Concrete 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: Concrete must be dry before application of this floor coating material. Concrete moisture testing must occur. In-situ relative humidity testing is recommended. Readings must be below 75% relative internal concrete humidity. Test methods can be purchased at www.astm.org, see F2170, or follow manufacturer's instructions. If moisture issues are present, the use of a moisture mitigation system may be a consideration. Please call Tennant Company Technical Support for further information / 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 85°F (29°C). Humidity must be less than 70% or the result may be a hazy appearance. DO NOT coat unless floor temperature is more than five degrees over the current, local dew point.
