Westcoat EC-11 Water-Based Epoxy

• USDA/FDA Compliant
• Water based
• Moisture Tolerant
• Chemical Resistant
• Long Pot Life
• Medium Gloss
• Very Durable
• Easy to Use
• Very Fast Drying
• No Induction Time

• EC-11 is designed to be used on concrete, metal, masonry or wood where a tough, chemical-resistant finish is needed.
• EC-11 is recommended for use as a medium-duty concrete sealer for interior floors.
• EC11 may also be used as a primer under many Westcoat Systems.

• The surface must be structurally sound, clean, dry and free of grease, paint, oil, dust, curing agents, laitance or any foreign material that will prevent proper adhesion.
• The concrete should be at least 2,500 PSI and porous or rough enough to allow the product to soak in.
• A minimum of 28 days curing time is required on all concrete.
• Prior to starting work, test existing concrete slab for efflorescence, moisture and hydrostatic pressure.

• Pre-cut and clean all cracks and joints with a concrete diamond blade to at least ¼ x ¼ inch.
• Prepare concrete to a profile equal to CSP 3-4 as specified by ICRI.
• Methods may vary according to the condition and hardness of the concrete.
• Other factors include the forecasted use of the surface and the environment in which it is to be installed.
• When preparing the surface use caution when shot blasting, scarifying too aggressively, leaving grind marks or grinding too smooth.

• All concrete should be tested for moisture before applying a seamless coating.
• If moisture emissions exceed 5 lbs/1000 square feet/24 hours (ASTM F1869) or if the relative humidity (RH) exceeds 75% (ASTM F2170), contact the manufacturer before application.

• Premix each component separately.
• For color consistency, box all part A’s. In a clean bucket, mix 2 parts A with 1 part B (by volume) of EC-11.
• Mix thoroughly with a low speed (400-600 rpm) drill motor for 3-4 minutes.
• Make sure to scrape the sides and bottom of the container during mixing.
• After mixing is completed, remove material from container within 5 minutes, as epoxy will begin to generate heat.
• Spread immediately onto the floor.
• As product is spread out, you will have longer working time (10-15 minutes at 70°F).

• Thin with water, up to 50%
• Amount will vary depending on use.

Will vary depending on the mil thickness applied and the porosity and texture of the surface, but in general, EC-11 will cover approximately 300-600 square feet per gallon as a primer, coating or sealer.

• As a primer, spray or squeegee and backroll thinned EC-11 onto the surface.
• Primer coat should be applied evenly and worked into the surface to help seal and avoid pinholes.
• When thinned, apply EC-11 at a maximum of 5 mils.
• Do not allow material to puddle.
• As a coating or sealer, apply EC-11 within 24 hours after the primer coat.
• Immediately after mixing, spread a strip of material onto the surface along the edges, where it will be “cut in” using a brush.
• Pour the remaining material near the “cut in” area and spread evenly using a trowel or squeegee and back roll using a 1/4 inch nap non-shedding roller.
• Depending on the look, thickness, chemical and abrasion resistance desired, 1 to 2 coats may be applied.

• You may re-coat as soon as the surface is dry to the touch in 1 to 4 hours, but no later than 24 hours.
• Light foot traffic may be permitted in 6 hours, normal traffic in 24 hours and vehicle traffic in 72 hours.
• All times are based on average temperature of 70F degrees and 50% humidity.
• Cooler temperatures will increase drying time.

• Uncured material should be removed with soap and warm water.
• Cured material should be removed mechanically or with an environmentally-safe solvent.

• This product is designed for professional use only.
• Be sure to measure and mix properly. Be aware of the pot life of mixed epoxy.
• Do not apply when temperatures are below 50°F or above 90°F.
• Hot or cold weather will affect dry times.
• Epoxy must be cured for a minimum of 24 hours before coming in contact with water.
• Skid-resistant additives are available, such as CA-30 or CA-31.
• For interior use only unless protected by a UV-resistant coating.
• Solvents may be required in cooler weather to lower viscosity and increase coverage of 100% solids.
• Please check with local laws governing the use of solvents.
• Do not allow Westcoat products to freeze.
