Hardwood Flooring
Installaon Guide
Job Site Inspecon & Acclimaon
• Bridgewell Hardwood Flooring should be one of the last
elements installed in new construcon. Cement, paint,
plumbing, heang and cooling systems should all be
installed prior to wood ooring and in nished and good
working order rst.
• Proper and constant temperatures should be at 68-74°F.
• All concrete slabs must have at least 3/4”plywood and 6 mil
polylm vapor-barrier aached. Each slab must be tested
for moisture content as well. It should be no more than
3 lbs./100 sq.  emissions, prior to installing hardwood
ooring.
• Preliminary moisture tesng can be done in the following
ways:
1. Use an approved moisture meter such as: Delmhorst
Moisture Meter Model J-200 or Tramex Concrete
Encounter and follow the manufacturers’ instrucons
for use.
2. Use polylm, such as a clear garbage bag or plasc drop
cloth, cut into 2’ x 2’ squares. Tape it down in several
places on the concrete suboor. Wait for 24-48 hours
and check for condensaon under the polylm, or for
dark moisture spots on the concrete. Either occurrence
may be a sign of excess moisture, and further tesng is
mandatory.
• A Calcium Chloride test and a PH alkalinity test will
determine the true moisture emissions and alkalinity of the
concrete oor. Follow all manufacturers’ instrucons.
1. For the Calcium Chloride test – the maximum
acceptable reading is 3 lbs./24hrs/100s q.  for
moisture emissions.
2. For the PH alkalinity test – on a pH number scale of
1-14, a reading between 6-9 is acceptable.
3. If either test yields unacceptable results the concrete
slab must be sealed with appropriate sealers, following
the manufacturer’s instrucons.
