Difference Between Sealers, Coatings and Floor Systems


What’s the difference between sealers, coatings and floor systems?


A sealer is typically anything that would be applied 5 mils thick or less and is used to seal and protect an existing surface.

An example of a high-quality sealer is Tri-Chem’s 144 Water-Based Hybrid Urethane Coating. This sealer is an ideal finish coat for all vertical and horizontal surfaces. It is abrasion and scratch resistant and designed to protect any surface, including: VCT, ceramic tile, concrete, epoxy, paint, metal, wood and more. Sealers not only protect existing surfaces, but can brighten up a room with a glossy finish and create an easily maintainable surface.

Floor Coatings

A floor coating is the next step up from a sealer and is usually between 5 mils and 20 mils thick.

An example of a durable floor coating is Z-Poxy, a 100% solids, no VOC coating. This super-strength epoxy coating is made for high-traffic floors and gives old, worn-out floors an abrasion-resistant surface that can stand up to acids, solvents, alkalies and temperature changes. Floor coatings also often come in a variety of colors.

Floor Systems

Lastly, floor systems are made up of several components. They range anywhere from 20 mils to 1/2 inch thick.

Our most popular floor system, 377, is available in both slurry-applied and trowel-applied versions. It has no VOCs and resists all kinds of harsh chemicals, making it an ideal coating for processing plants and commercial kitchens. 377 has a coefficient of expansion similar to that of concrete allowing it to tolerate thermal shock and temperature swings. This floor system has a topcoat component, 377 D, that is used to make 377 TR and 377 SL more durable and easier to clean.
