Installation Guide

REV 11.14.2019

JOBSITE TESTING

1. Before jobsite testing, the building envelope must be sealed (walls,

roofing, windows, doorways etc., installed).

2. The installation area and materials to be installed shall be maintained

at a minimum of 65°F (18.3°C) and a 85°F (29.4°C) for 48 hours

before, during and for 48 hours after completion of the installation.

Relative humidity level extremes should also be avoided. General

recommended humidity control level is between 35–55%. If a system

other than the permanent HVAC source is utilized, it must provide

proper control of both temperature and humidity to recommended or

specific levels for the appropriate time duration.

3. Test sites must be properly prepared and protected for the duration of

testing to achieve valid results.

4. Surface Flatness for all Subfloors:

1. The surface shall be flat to 3/16” (3.9 mm) in 10 ft. (3050 mm)

and 1/32” (0.8 mm) in 1 ft (305 mm).

2. To check flatness, place a 10 ft straight edge, string, laser level

or use another suitable method on the surface and measure the

gap.

5. Concrete Subfloors:

1. Concrete subfloors must be finished and cured, free of all

sealers, coatings, finishes, dirt, film forming curing compounds,

or other substances that may prevent proper bonding of the

flooring materials (ACI 302.1 and ASTM F710).

2. Randomly check concrete subfloor for porosity using the drop

water test. Place a 1-inch diameter drop of water directly onto

the concrete subfloor. If the water droplet does not dissipate

within 60 to 90 seconds, the subfloor is considered non-porous.

3. Concrete subfloors must have a minimum compressive strength

of 3,000 psi. Concrete subfloors shall not consist of lightweight

concrete or gypsum.

4. Moisture Testing: Perform either the preferred In-situ Relative

Humidity (RH) Test (ASTM F2170) or the acceptable Moisture

Vapor Emission Rate (MVER) Test (ASTM F1869). For acceptable

moisture limits please refer to the specifications of the adhesive

being used.

5. Alkalinity: Must test surface alkalinity (ASTM F710). A 7.0 to 9.0

pH is acceptable.

6. Wood Subfloors and underlayment panels shall have the

moisture content tested using a suitable wood pin meter.
