STEP 5: TESTING FOR MOISTURE CONTENT
For Wood and Other Sub-Floors Types:
Using a quality moisture meter, measure the moisture content of both the sub-floor and the hardwood flooring.
Sub-floors must not exceed 12% moisture content and the difference between sub-floor and
hardwood flooring cannot exceed 4%. If sub-floors exceed this amount, an effort should be made to locate
and eliminate the source of moisture before further installation.
A moisture barrier (StrateStuff Safeguard is
recommended; 8 mil polyethylene film minimum) is required in the floating applications of BR-111
™
5/16" Engineered hardwood flooring products.
For Concrete Sub-Floors:
Concrete sub-floors should always be checked for moisture content prior to the installation of wood flooring.
Please note that these tests do not guarantee a dry concrete slab year round. The two most common moisture
tests include:
•
Calcium Chloride Test – Moisture transfer should not exceed 3 lbs/1000 square feet with this test. One test must be
performed every 250 square feet. Calcium chloride tests can be found in flooring retail stores or retail websites on the
internet such as www
.taylortools.com or www.moisturetestkit.com 1-888-216-TEST (8378).
•
Tramex Concrete Moisture Encounter Meter – Moisture readings using a metering device should not exceed 4.5 on
the upper scale (www
.tramexltd.com).
STEP 6: MOISTURE BARRIER SYSTEMS
StrateStuff Substrate Safeguard — Protects against moderate to high moisture emissions from the sub-
floor. Recommended for use with BR-111
™
flooring, apply StrateStuff Substrate Safeguard following
manufacturer’s instructions. When used in conjunction with StrateStuff Urethane Adhesive, BR-111
™
extends a
15-year moisture protection warranty to the original purchaser of the installation. Please see product label
and literature for full details.
