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.

to be dry. Be careful not to clump the material and cause high spots.
You will need about 3 to 6 lbs of sand for ever 10 square feet. If
terminating the system with tape broadcast up to the tape and remove the
tape from the edges after the material has cured for only about 30
minutes. Never walk in the wet material without spiked shoes.
Never walk on the floor after it has been broadcast with silica.
7. Allow to cure overnight. Sweep off the
excess silica sand with a stiff bristled broom. Stone with a rubbing
stone if a finer finish is required. Vacuum the floor completely.
C. Sealing the system.
The finish of the floor is dependent on the number of
coats applied to the surface. 1 coat will result in a rougher
floor, and 2 or more coats will result in smoother finishes. The
