Limitations
MOISTURE CONTENT LIMITATIONS: Titebond 231 Acrylic Polymer Wood Flooring Adhesive may be used for
above-, on- and below-grade applications and on all substrates listed in this specification guide. All applications are susceptible to moisture and should be tested for moisture prior to installation in several locations within the installation area.
Acceptable conditions of concrete for above-, on- and below-grade applications are:
- Less than 3 lbs. /1000 sq.ft./24 hours on a Calcium Chloride Test (ASTM F1869)
- Less than a reading of 4.5 on a Tramex Concrete Moisture Encounter
- Relative humidity (RH) of 75% or less when tested with an in situ probe (ASTM F2170)
Acceptable conditions of wood substrates are a moisture reading of less than 12% or be no more than 4% different from the flooring being installed when using a Tramex, Delmhorst or equivalent wood moisture meter.
If subfloor moisture conditions do not meet above guidelines at the time of flooring installation, or they could exceed them at any time after installation, then a Titebond Moisture Control System should be used.
CAUTION: Do not sand, scour or abrade any material that is suspected of containing asbestos fibers. Asbestos is known to cause cancer. Federal law requires that asbestos be handled by a licensed and certified hazardous materials contractor.
