ESD Rubber Tile: Installation

Moisture Barrier Information

Staticworx® is not responsible for any floor installation failures associated with unaddressed pre-existing site conditions like vapor transmission, moisture permeation, contaminated concrete and damaged subfloors. Always determine if there is a vapor barrier below concrete subfloors before beginning any flooring installation. All subfloors should be tested for moisture using ASTM test methods. For information about moisture and a complete list of ASTM test methods for determining potential moisture problems visit http://Staticworx® .com/articles/articles-moisture-barrier.htm.

Flex-Floor ESD Rubber Tile Installation

I. JOB SITE CONDITIONS
A. Installation should not begin until after all other trades are finished in the area. If the job requires other trades to work in the area after the installation of the floor, the flooring should be protected with an appropriate cover.

B. Areas to receive flooring should be weather tight and maintained at a minimum uniform temperature of 65° F (18° C) for 48 hours prior to, during and after installation.

II. SUBFLOORS
A. Metal subfloors shall be sand blasted or otherwise abraded to achieve bright, shiny bare metal. There should be no rust, scaling or other contaminants on the metal surface.

B. The subfloor shall be dry, clean, smooth, level, and structurally sound. They should be free of dust, solvent, paint, wax, oil, grease, asphalt, sealers, curing and hardening compounds, alkaline salts, old adhesive residue and other extraneous materials, according to ASTM F710.

C. The subfloor should be smooth to prevent irregularities, roughness, or other defects from telegraphing through the new flooring. The surface should be flat to the equivalent of 3/16" (4.8 mm) in 10 feet (3.0 m).

D. All saw cuts (control joints); cracks, indentations and other non-moving joints in the concrete must be filled with a Portland based patching compound.

E. Expansion joints in the concrete are designed to allow for expansion and contraction of the concrete. If a floor covering is installed over an expansion joint, it more than likely will fail in that area. Expansion joint covers designed for resilient floor coverings should be used.

F. Always allow patching materials to dry thoroughly and install according to the manufacturer's instructions. Excessive moisture in patching material may cause bonding problems or a bubbling reaction with the E-Grip II for ESD adhesive.

G. Maximum moisture vapor emission of the concrete must not exceed 5.0 lbs. per 1000 sq./ft in a 24 hour period as measured by the calcium chloride moisture emission test conducted in accordance to ASTM F1869. If the emissions exceed the limitations, the installation should not proceed until the problem has been corrected.

H. It is essential that pH tests be taken on all concrete floors. If the pH is greater than 9, it must be neutralized prior to beginning the installation.
