EC-34 Epoxy Topcoat

Description EC-34 Epoxy Topcoat is a two-component, 100% solids, medium viscosity, low odor, high-build, chemical resistant epoxy.

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 or broadcast coat and not as a top coat.

Inspection Surface must be structurally sound. The surface must be dry and free of oil, grease, curing agents, dirt, dust or other foreign material that may prevent proper adhesion. The concrete should be porous and be able to absorb water. The surface must be porous or rough enough to allow the product to soak in. A minimum of 28 days cured is required on all concrete. Before starting flooring work, test existing concrete slab for efflorescense, moisture, and hydrostatic pressure.

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 around pools, scarifying too aggressively, grinding marks or grinding too smooth. When applying over existing epoxy, sand the surface with a floor buffer and 80 grit sand paper, remove debris and wipe with denatured alcohol or acetone just before new application.

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 30 or 50, grit sandpaper. You may mechanically profile by grinding, shot blasting, scarifying, or water blasting. Methods may vary according to the thickness of the coating to be applied, and the condition

Moisture All concrete should be tested for moisture before applying a seamless coating. Water vapor transmission upwards through on-grade concrete slabs may result in loosening of epoxy floors or improper curing of epoxy materials. If moisture emissions exceed 3 lbs./1000 sq ft. contact the manufacturer before application.


Mixing As a coating, pre-mix each component seperately. Mixing should be done by using a mechanical mixer. Mix 2 parts of Part A with 1 part of Part B, by volume of EC-34, into a clean container. Make sure to scrape the sides and bottom of container during mixing. Mix only the amount of material that can be used within the pot life. For an epoxy mortar, mix 2 to 5 parts of silica sand or other dried aggregate by volume to 1 part of mixed EC- 34 and mix until uniform in consistency. For a slurry filler, combine 1½ gallons of mixed EC-34 with 1½ gallons slurry filler powder (a combination of Silica Sand and Silica Flour) using a mechanical mixer.

Thinning EC-34 can be thinned with acetone typically 1 to 2 quarts.

Coverage As a coating, 100-300 square feet per gallon depending on conditions or specified mils. As a mortar, 1 gallon of epoxy mixed with 5 gallons of sand will yield approximately 3 to 4 gallons of mortar. As a slurry filler, 1 ½ gallons of epoxy with 1½ gallons of slurry filler powder will cover approximately 100 sq. ft. at 40 mils.
