PRODUCTS

Mannington's ColorFields Sheet Rubber Flooring
Because Mannington Commercial Rubber Sheet Flooring products are intended for use in high-traffic areas, underfloor selection
and preparation are especially important. In most cases, remove all existing floor coverings before installing these commercial
products. (You must strictly follow all federal, state, and local regulations regarding the removal of existing flooring.) Furthermore,
all concrete under floors must be tested for moisture before starting the installation. Mannington requires that the concrete be
tested for moisture using either the anhydrous calcium chloride test following ASTM F 1869 procedures and or the in-situ relative
humidity test following ASTM F 2170. Maximum permissible MVER are determined by product construction and adhesive type.
NOTE: While either of the industry accepted moisture-testing methods may be used, the results are not exchangeable, if both
tests are performed they must both be in the acceptable range to be considered valid.

HANDLING INSTRUCTIONS

It is imperative to maintain the material, adhesive, and job site at a minimum temperature of 65°F and a maximum temperature of
85°F for 48 hours before, during, and after the installation. To acclimate properly, the flooring material must be unrolled and
allowed to relax overnight before proceeding with the installation. Remember; maintain the adhesive, floor covering, and job site
between 65°F and 85°F for a minimum of 48 hours before, during, and after the installation.

SUBSTRATE CONSIDERATIONS AND PREPARATION

Concrete Subfloor Requirements:
The General Contractor must provide a finished concrete subfloor ready to receive Mannington's ColorFields Rubber Flooring.
Subfloors must be smooth and level within a tolerance of 1/8" (3 mm) in a 10' (3.05 m) radius.
Minor surface cracks or grooves must be filled with a good quality Portland cement based patching or leveling compound with a
minimum compressive strength of 3,500 psi. High spots, bumps and peaks must be repaired prior to installation.
Concrete subfloors must be dry, sufficiently porous, smooth, clean and free of paint, wax, dust, oil, sealers, grease, curing agents,
surface hardeners, old adhesives and any other contaminants that could inhibit or reduce bond strength. Concrete surfaces that
are powdery or scaly are not acceptable.
Although a smooth, flat concrete surface is required, a shiny, slick, nonporous surface is to be avoided. To roughen up a concrete
substrate, remove sealers and increase the porosity of the substrate, mechanical abrasion options are recommended. A "shot
blaster "or "blast track machine" using a No. 275 shot is recommended. Also, scarifiers, of various descriptions, are also
acceptable. Nonporous surfaces must be mechanically roughen or "opened" up. Chemical methods, of any description, are not
recommended.
An over-porous surface is to be corrected with a Portland cement based patching or leveling compound with a minimum
compressive strength of 3,500 psi.
As a general rule, a Concrete Surface Profile (CSP), as defined by the American Concrete Institute, of about 1 is recommended.
Mannington requires that the concrete be tested for moisture. The use of the anhydrous calcium chloride test, following ASTM F
1869 procedures, is acceptable. The test should generate results not exceeding 3 pounds of moisture transpiration for 1,000 Sq.
Ft. within 24 hours. In-situ relative humidity tests following ASTM F 2170 is also acceptable and should generate results not
exceeding 75 percent.
Never execute moisture tests until the building's HVAC has been operational for at least 7 days. It is imperative that the site
conditions (temperature and humidity) are constant in the building and reflective of in-service conditions.

Adhesion (Bond) Test

• Adhesive Bond Tests should be performed as a final and authoritative "real world" check.
• A bond test of at least 24-hour duration should be performed.
• ColorFields Rubber Sheet Flooring can be cut into 9"x 9" sample sizes.
• Install samples using the recommended adhesive and procedures.
• After 24 hours, removing the test samples should be difficult.
• Most of the cured adhesive should remain bonded to the subfloor.
• If proper bond is not accomplished, do not proceed with the installation.
