DESCRIPTION:

White, two-component, 100% solids epoxy primer or build coat. Applied at 3-5 mils for priming or up to 30 mils as a build coat.

USES:

• To level floor after mechanical prep

• Use as a concrete primer before applying another epoxy or urethane.

• Use over other 100% solids epoxies.

• Use as random crack filler when combined with thickening agents.

ADVANTAGES:

• Seals concrete and provides a more consistent background (better hide) for urethanes that are lighter in color.

• Complies with VOC regulations

STORAGE: Materials should be stored indoors between 65ºF (18ºC) and 90ºF (32ºC).

SHELF LIFE: Minimum 1 year from date of manufacture.

OPTIONS:

Colors: Tennant colorants (Battleship Gray, Black, Canada Gray, Light Gray and Medium Gray) may be added to tint Eco-CEP. Use colorants at a rate of one pint per 4-gallon unit of Eco-CEP. Due to the high amount of white in Eco-CEP, all colors will be much lighter than the normal effect. For example, the addition of 1 pint of Canada Gray to 4 gallons will tint the epoxy closer to Light Gray.

LIMITATIONS:

UV/Light Stability: This product is not light stable and will yellow/amber over time.

Contamination (Fisheyes): Product may fisheye if oil, silicones, mold release agents or other contaminants are present.

Properties: Product designed as primer and build coat only.

For enhanced chemical resistance and wear characteristics, product must be topcoated.

IMPORTANT:

READ AND FOLLOW ALL PRECAUTIONS AND

INSTRUCTIONS BEFORE PROCEEDING.

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. Calcium chloride testing or in-situ relative humidity testing is recommended. Readings must be below 3 pounds per 1,000 square feet over a 24-hour period on the calcium chloride test or below 70% relative internal concrete humidity. Test methods can be purchased at www.astm.org, see ASTM F1869 or F2170, respectively or follow instructions from the suppliers of these tests.

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.

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

• Shed Resistant, Short (3/8") Nap Rollers

• Spiked shoes

• 80 grit sandpaper

[Tennant Part No. 65450]

• 100 grit sandpaper

[Tennant Part No. 65451]

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

Detergent scrub and rinse with clean water to remove surface dirt, grease, oil and contaminants.

THIN FILM APPLICATIONS (3-10 mils):

Acid Etch (bare concrete): Detergent scrub and rinse with clean water.

Tennant Eco-Prep™ or Diamond Grind: Scrub with Tennant Acid Wash and rinse with clean water (results of diamond grinding may vary depending on technique and the hardness of the concrete. Additional mils may be required).

Light Blast: Use magnetic broom to remove excess shot, sweep to remove large debris and vacuum to remove fine dust.

THICK FILM APPLICATIONS (11-30 mils):

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.

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, 100% solids epoxy or with a semi-rigid joint filler such as Eco-PJS™ or Eco-EJF™. Construction joints less than one inch wide may also be filled with Eco-PJS. Isolation or expansion joints must be filled with a flexible material designed for this purpose.

APPLICATION - PRIMER COAT

A thin coat of primer will 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. A gallon of Eco- CEP will cover:

535 ft2 @ 3 mils wet/dry film 400 ft2 @ 4 mils wet/dry film 321 ft2 @ 5 mils wet/dry film

PREMIX PART A using a Jiffy® mixer blade and slow speed drill. (This is required for both 4-gallon and full-fill 5-gallon units.) For full-fill 5’s, pour out 3 gal 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-CEP PART B TO PART A (4 GALLONS MAX).

For full-fill 5’s, pour out 1 gal 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 3 parts PART A to 1 part PART B by volume.

IMMEDIATELY POUR ALL OF THE MIXED MATERIAL

onto the floor in a single bead.

PUSH THE FLAT SQUEEGEE at an even speed with down pressure. The squeegee should be pushed to apply maximum pressure and therefore 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 and push at an even speed with slight down pressure. NOTE: Eco-CEP 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-CEP. For the best adhesion, apply the buildcoat within the following times after application of primer.

APPLICATION - BUILD COAT - (IF REQUIRED)

COVERAGE RATE will depend upon required thickness. A gallon of Eco-CEP will cover:

160 ft2 @ 10 mils wet/dry film 107 ft2 @ 15 mils wet/dry film 80 ft2 @ 20 mils wet/dry film NOTE: Total Eco-CEP (prime and build coat) should not exceed 35 mils.

REPEAT STEPS used for mixing and spreading of the primer coat. A notched squeegee can be used to increase the thickness applied.

*1/16" notched squeegee to apply 10-15 mils *1/8" notched squeegee to apply 15-20 mils *1/4" notched squeegee to apply more than 20 mils *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-CEP is applied and there is room to roll, a second person will BACKROLL THE MATERIAL with a 1/4" roller to a smooth and uniform appearance.

NOTE: Get off the Eco-CEP as soon as possible.

APPLICATION OF ADDITIONAL COATINGS

If Eco-CEP is being topcoated with Eco-HTS™, Eco-HTS™ 100, WearGuard™-ITS, WearGuard™-420, WearGuard™-HTS or WearGuard™-CRU (Clear, White, Canada Gray or Light Gray) at 65-90°F (18-32°C), it does not need to be sanded if applied within 24 hours of the Eco-CEP application.

SANDING REQUIRED

Eco-CEP must be thoroughly sanded if applying Eco-HPS™, Eco-HPS™ 100 or any of the previously mentioned topcoats outside of the 24-hour recoat window. See the following list of times Eco-CEP needs to cure before it can be sanded.

APPROXIMATE SAND TIME (hours)

Eco-CEP 24 20 16 12 8

Eco-CEP 20 16 12 9 6

For all coatings, use 80 grit sandpaper/60 grit screen except for Eco-HPS, Eco-HPS 100 and WearGuard™-CRU–use 100 grit sandpaper/80 grit screens. 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.

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: 800-553- 8033.

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.
