Applying Product

Before applying as a primer, prime the surface using EC-12 Epoxy Primer or EC-11 Water-Based Epoxy (See Product Specification Sheets) As a coating, apply EC-34 within 24 hours after the primer coat. 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 ¼ 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 look, thickness, chemical and abrasion resistance

Dry Time You may re-coat as soon as the surface is dry to the touch or in about 4 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
