What are the Epoxy Mortars & Urethane Mortars Floor Systems?

Epoxy Mortar is a heavy-duty, troweled floor topping that can be used to patch or resurface concrete, metal, and wood floors. It is composed of a unique blend of aggregates and polymer resins. The product offers superior durability and resistance to heavy traffic.

Epoxy Mortars also withstand the abuse of a wide range of chemicals, acids, alkalies, fatty greases, salts, and solvents. The product can be troweled directly onto the floor without prior application of a bonding agent and it can also be used to repair holes and complete other patch jobs.

Urethane Mortar/Cement is a three-component urethane mortar/slurry that has outstanding wear performance and can withstand higher heat exposures than typical unmodified urethanes.

Urethane Mortars have good thermal shock capabilities and are a good choice for hot wash-down areas. They are durable enough to withstand heavy and abusive service.

This product is recommended for resurfacing areas where a durable shock-resistant surface is needed. The product can be applied as a stand-alone or as part of a broadcast system consisting of an industrial quartz/sand broadcast and a novolac topcoat.

What are the 4 Facts about Urethane Mortar?

  1. It’s a mixture of urethane and cement
    Urethane cement is made by mixing polymer urethane with cement and aggregate. Urethane and concrete are both durable materials on their own. When they are paired together, they yield one of the industry’s most durable flooring options.
  2. Urethane mortar can be applied directly to concrete.
    Not like other coating systems, urethane mortar can be installed directly on concrete as a stand-alone system. It doesn’t require a primer or topcoat which makes the installation a lot easier and faster.
  3. Urethane mortar is resistant to moisture
    A separate moisture vapor mitigation/control system is not necessary. When a urethane cement system is applied, the floor becomes resistant to some of the toughest conditions in the industries including moisture, chemicals, and thermal shock, etc.
  4. Urethane mortar is visually appealing
    A tough floor doesn’t have to be ugly. Because it can be used with colored topcoats, additives, and decorative broadcast aggregates. The design options are unlimited. The end result is a floor that is just as durable and long-lasting as the one you could find in any industrial building, but far more aesthetically appealing.

What is Thermal shock?

Thermal shock to a floor system occurs when a liquid comes in contact with the floor where there is a large temperature gradient and the resulting stress may damage the floor. Example: cleaning a very cold floor with a steam generator.

Urethane mortars can withstand the stress of thermal shock far better than concrete and typical epoxy systems.

What is the typical thickness of a mortar system?

Minimal thickness is often 1/8″, but 1/4″ is typical of urethane and epoxy mortar systems. Some systems can also be installed as a slurry/broadcast system and can be gauged thinner than 1/4″.

Are Mortar Systems more costly than traditional epoxies?

Yes. Epoxy and urethane mortar does cost more and is placed at a much thicker film thickness than traditional epoxies and urethanes. The labor cost to install is higher too.

How Can We Help?

Epoxy flooring had been the “go to” product for many decades due to the low cost, widespread availability, and very good all-around performance. Urethane mortar flooring is now “taking up the slack”, in areas where thermal shock is common and industries where epoxy typically fails.
