Applications & Uses
- Markets
- Application Area
- Uses
- EC-34 epoxy is used to create industrial seamless floors in manufacturing plants, mechanical warehouses, industrial kitchens and garages.
- It is best used as a filler coat, broadcast coat or topcoat.
- Inspection
- 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.
- Preparation
- 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.
- 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-34.
- 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).
- Coverage
- Coverage will vary depending on condition of surface and desired thickness.
- As a primer: 300-500 square feet per gallon.
- As a coating: 100-300 square feet per gallon.
- Applying Product
- As a primer, spray or squeegee and backroll thinned EC-34 onto the surface.
- Primer coat should be applied evenly and worked into the surface to help seal and avoid pinholes.
- When thinned, apply EC-34 at a maximum of 5 mils. Do not allow material to puddle.
- As a coating, apply EC-34 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 to 3/8 inch nap, non-shedding roller.
- A notched trowel or squeegee will help regulate the thickness and a porcupine roller will help to release trapped air and minimize bubbles.
- Depending on the look, thickness, chemical and abrasion resistance desired, 1 to 2 coats may be applied.
- 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 degrees 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.
