The following are important recommendations for handling and storing Oak
Flooring.
UNLOAD IN DRY WEATHER-
If possible, unload
flooring in good weather -- never unload in the rain.
DELIVERY-
If the atmosphere is damp, cover each
truckload of flooring with a tarpaulin until it can be unloaded.
Never deliver or store unprotected flooring in rain,
sleet, or snow.
PROPER WAREHOUSING-
Kiln dried flooring should be
stored in an enclosed building that is well ventilated with weather proof
windows and located in areas where similar fine millwork is stored. The storage
area within the building should be clean and dry. Provide good air circulation
around stacks of flooring and prevent water drainage into the storage area.
PREVENT CONDENSATION-
When air in a building is
warmer than outside air, moisture may form on the underside of the non-insulated
roof and affect flooring. Insulation in the roof or walls can prevent
condensation. A covered area can also provide protection. If this is not
possible, all top pallets should be covered with polyethylene film or other
water proof covering. The building should not be heated, unless
temperatures are maintained & controlled humidity provided.
Continual dry heat may dry flooring below its manufactured moisture content. Too
dry flooring could result in buckled floors when flooring is delivered to the
job and immediately installed without proper acclimation.
MOISTURE CONTENT-
NOFMA MEMBERS' oak flooring is
manufactured at 6-9% moisture content. It is desirable to maintain this average
moisture content as close as possible.
ACCLIMATE STOCK-
Recently manufactured flooring
should be allowed to acclimate to the area. This helps prevent cracks which may
result if the flooring is installed while at a higher moisture content,
oversized, and later shrinks.
ROTATE STOCK-
Maintain a -first in -first out-
policy. Flooring which is received first should be the first shipped out.
Maintain separate flooring stacks, one stack for the old flooring, and one for
new flooring. Do NOT place new flooring on top of the old at any
time. Use the oldest flooring before using the new.
REGULARLY CHECK STORAGE AREA-
Be sure there are no
roof leaks, wall leaks, or condensation problems. Cracks in concrete block walls
can permit rain or melting snow to leak on flooring. A monthly check is
preferred.
