Enabling faster returns to service when installing flooring

By Casey Ball
Whether building a new facility or retrofitting an existing one, downtime can be a construction manager’s worst nightmare. It can interfere with the project’s overall productivity, creating delays that hold up multiple service providers from performing their duties.

Unfortunately, when the time comes to install or repair a resinous flooring system, downtime is a given for nearly every discipline involved. However, unnecessary delays can be prevented by knowing more about the different types of flooring and their limitations, allowing design/construction professionals to select the system best aligning with the project timeline, budget, and longevity requirements.

To avoid contaminating a new resinous flooring system, other construction activities must often stop, and personnel must clear the area throughout the multistep—often multiday—installation. The applicator’s goal is to then return the facility to service as quickly as possible following the flooring installation. To speed up installations and minimize project downtime, it is best to select flooring systems that apply and cure quickly. Such products include urethane concrete coatings, which can allow foot traffic within four to eight hours of application and full service within six to 12 hours.

Additionally, methyl methacrylate (MMA) systems allow foot traffic after one hour and full service in two hours, with the caveat they typically require additional project setup time to mitigate odours. Conventional epoxy mortar systems are another common alternative, but they typically need a 24-hour curing time before returning to service. The three systems also differ in their number of application steps and total installation times, with urethane and MMA systems offering enhanced efficiencies.

For commercial facilities, there are three commonly used flooring system chemistries.
