Although bare concrete flooring is durable, coating the surfaces will make it last longer. The membrane provides a barrier to moisture, dirt buildup, and wear from traffic. When weighing options, you’ll come across epoxy and polyurea floor coatings. By knowing how the two compare to each other, as outlined below, you can decide which to use.

Epoxy Coatings

An epoxy coating is a thermoset resin that ranges from thin to thick, allowing options for low- and high-traffic areas. Epoxy must bond to a clean, porous surface, so you must remove all polishes, sealants, and oils first.

Although thicker coatings are impact-resistant, epoxy is vulnerable to high temperatures. When you drive into a garage or warehouse, the resin could stick to hot tires, causing vehicle and flooring damage. The thick membrane can become brittle and crack when concrete expands and contracts, too. Chemicals and oils from leaky cars and service trucks can leave unsightly stains on the surface.

Polyurea Floor Coatings

Polyurea, a subgroup of polyurethane, is a flexible polymer that will expand and contract with the concrete to prevent cracking. Polyurea floor coatings can resist substantial impacts like epoxy-covered surfaces, but also repel moisture to prevent corrosion. The material won’t melt and peel when exposed to high temperatures, either, or stain if salt, chemicals, or gas reach the floor.

Polyurea floor coatings are ideal for patios and rooms that receive ample sunlight, as the membrane will reflect UV rays to keep the surfaces from fading. As it takes about a day for polyurea to cure, you can start using the floors again quickly. 

To take advantage of the benefits polyurea floor coatings provide, call the technicians at SealTek Surface Coatings. Based in O’Fallon, MO, and serving the St. Louis area since 2013, the team specializes in the one-day installation of durable polymer floor coatings that are stronger than alternative materials.
