Limitations
MOISTURE CONTENT LIMITATIONS: Titebond 991 PROvantage 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.
- Do not use Titebond 531 Plus for moisture control with this adhesive, use Titebond 531
- Do not install solid wood below-grade
- Do not use on concrete with curing agents or sealers (except for recommended Titebond or Franklin products)
- Do not allow foot traffic for 4 hours after installation
- Do not use as a subfloor leveler
- Installations in dry or cool climates or over dry subfloors will take longer to cure
- Temperature and humidity will affect the open time and the cure time of the adhesive
- Open time is 30-45 minutes depending on temperature and humidity
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.
