Mechanical Room Floor

Guide Specification


General Information

Epoxy.com Mechanical Room Floor is a fluid applied, resilient flooring system for concrete and wooden floors in mechanical rooms or other applications where crack isolation is required.  The resilient properties of the floor help to provide sound deadening quality and cushioning underfoot.

Surface Preparation

Surface preparation is extremely important to insure the success of any flooring system application.  All substrates should be prepared in accordance with Epoxy.com Surface Preparation Guide that can be found at: www.epoxy.com/surfaceprep.aspx or a copy can be requested from Epoxy.com Technical Support Department.  Specific attention should be given to the following:

A.  Concrete Placement: A properly working moisture vapor barrier under slabs on and below grade to prevent the migration of moisture vapor transfer.

B. Curing and finishing Techniques of the Concrete Substrate.

C. Concrete should be at least 28 days old.

D. Previous contamination of the substrate should be completely removed

E. Current condition of the concrete.

The temperature and humidity conditions in the area that will receive the flooring should be check.  Ideal conditions are 75°F with a minimum temperature of 50 °F is required for the proper curing of the floor.
