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/1,000 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.
STEP 7: PREPARATION FOR SPECIFIC SUB-FLOOR TYPES
Sub-Floor Type: Concrete Slabs
Glue-Down Application – Indusparquet
®
5/16" & 7/16" can be glued directly to high compression strength concrete slabs
using the appropriate adhesive. BR-111
™
recommends using StrateStuff Adhesive in conjunction with StrateStuff Substrate
Safeguard for an added moisture protection warranty. See StrateStuff product labels and literature for details. Please
carefully read and follow the manufacturer’s instructions.
Unless using the StrateStuff system (StrateStuff Urethane Adhesive and StrateStuff Substrate Safeguard), do not use any
other concrete sealer or install over existing sealers.
All concrete sub-floors must be tested for moisture
content, especially adjacent to exterior walls and plumbing fixtures. Visual checks are not acceptable.
Please refer to the “Step 5: Testing for Moisture Content” section. Regardless of current moisture
readings, BR-111
™
recommends applying StrateStuff Substrate Safeguard to protect against future sub-floor
moisture fluctuations.
Sub-Floor Type: Acoustic Concrete
Glue-Down Application – Acoustic concrete sub-floors must have a minimum compressive strength of 2500 PSI. Because
acoustic concrete contains large quantities of gypsum, the surface must first be coated with a primer/surface hardener as
recommended by the concrete manufacturer. Perform appropriate moisture tests.
