- Uses
- EC-38 is primarily designed for use on concrete floors, tables and counter tops.
- Liquid Dazzle® Epoxy can be topcoated with a variety of sealers from high gloss to satin, as desired.
- 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-38.
- 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
Thinning of EC-38 is not recommended.
- Coverage
- Coverage will vary depending on condition of surface and desired thickness.
- As a coating: approximately 50 square feet per gallon.
- Applying Product
- Applying Product Apply EC-38 with an 1/8 inch notched trowel, being sure to get even coverage over the entire floor, to achieve the published coverage rate.
- Back roll the EC-38 with a loop roller to create an even look.
- To help reduce the possibility of bubbles, you may use a porcupine roller at this stage of the application.
- To avoid bubbles, best to apply EC-38 when temperature is dropping and in an area that is not in direct sunlight.
- After loop and porcupine rolling, the dynamic drift begins to change the look of the coating.
- 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.

- Avoid breathing vapors, it is strongly recommended that respirators are worn.
- Prolonged or repeated skin contact can cause slight skin irritation.
- All epoxies have the potential of causing skin irritations or allergic reactions.
- Be careful not to get on skin, clothes or in eyes.
- Gloves are strongly recommended.
- If splashed in the eye, flush with warm water and contact a physician if blurring persists.
- Solvent based products are extremely flammable, extinguish all pilot lights and sources of ignition such as electrical motors.
- Be sure to have adequate cross ventilation prior to installing.
