NJ USDA Epoxy Floors, selecting a brand.

The most notorious epoxy topping application is without a doubt a wash-down floor in a food processing plant. The constant wash-down cycle with water, detergents and in some cases steam will eventually break-down even the best polymer flooring material.
Once oils and detergents get in between the overlayment and the substrate, seperation begins.

When pursuing a product for a wash-down floor subject to thermal shock look for a urethane mortar or moisture insensitive hybrid like HD-501, from Legacy Industrial. HD-501 will shrug off the thermal shock and detergent. It requires no primer and will even bond to existing systems that are still in good condition.
