Westcoat EC-12 100% Solids Pigmented Epoxy Primer 1-1/2 Gallon Kit


About

Westcoat EC-12 Epoxy Primer is a two component, 100% solids, low viscosity, moisture tolerant, fast drying, high strength and multi-purpose epoxy primer.

Specs

  • Coverage: approx. 300 square feet per gallon
  • VOC Content: 0 g/L
  • Mix Ratio: 2:1 (by volume)

Instructions

Preparation

Pre-cut and clean all cracks and joints with a concrete diamond blade to at least 1/4 x 1/4 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. Please refer to desired System Specification Sheet for more information on preparation.


Moisture

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.


Mixing

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-12. 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).


Thinning

Thin EC-12 with 1 to 2 quarts of CA-23 or acetone or in some cases, EC-12 may be thinned up to equal parts with CA-23 or acetone. Thinned material must be applied at less than 5 mils to cure properly. Do not allow material to puddle.


Coverage

EC-12 covers up to 300 square feet per gallon under normal conditions, which will achieve 5.2 dry mils. EC-12 may be applied at a heavier rate to achieve a higher build system or to accommodate the broadcasting of aggregates.


Applying Product

As a primer, immediately after mixing, spread a strip of the batch 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.

As an intermediate coat, mix and apply without solvent at the desired thickness using a notched trowel or squeegee and backroll. The addition of silica flour or silica sand will add body and help to build up more cost effectively. Please refer to desired System Specification Sheet for more information on applying the product.


Dry Time

You may re-coat as soon as the surface is dry to touch or in about 4-8 hours (but not later than 24 hours). Light foot traffic may be permitted in 8-10 hours, light vehicle traffic in 48 hours, heavy traffic in 3 days. All times are based on average temperature of 70°F and 50% humidity. Cooler temperatures will increase drying time.


Clean Up

Uncured material should be removed with an environmentally-safe solvent. Cured material should be removed mechanically.


Limitations

  • 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.
