Wood is naturally porous and can
absorb and release moisture. If the humidity in your facility rises, your wood
floor will absorb that moisture, causing it to expand. If the humidity falls,
your wood floor will release moisture, causing it to shrink. Many installations
include expansion voids around the perimeter and around columns or floor
inserts, plus expansion joints built into the floor surface. These features
permit natural, normal expansion and contraction without damage to the floor. Too
much moisture causes abnormal expansion, which can lead to cupping or buckling
of your floor. In abnormally dry conditions the wood will contract, leaving
separations between flooring strips.
Six Steps For Proper Daily
THE FLOOR DAILY with a
properly treated dust mop. If the floor is used heavily, sweep it up to three
times per day.
SPILLS and any
moisture on the floor surface.
SURE THE HEATING/VENTILATING/AIR CONDITIONING SYSTEM IS FUNCTIONING PROPERLY and set to maintain indoor relative humidity’s between 35 percent
and 50 percent year round. In areas of consistently high or low outside
humidity, a 15 percent fluctuation will not adversely affect the maple.
HEEL MARKS using an
approved floor cleaner applied with a soft cloth or a dust mop. Contact your
floor finish manufacturer for approved cleaning products.
FLOOR FOR TIGHTENING OR SHRINKAGE. During wet weather, check for water leakage around doors and
windows. Remove debris from expansion voids.
PROTECT THE FLOOR when
moving heavy portable equipment or lifts. Ensure portable equipment does NOT
have crowned wheels or wheels that include center ridges remaining from the
molding process. These types of wheels can create very significant point loads.
Never Do the Following:
NEVER shut down the ventilation system in your
facility for a prolonged period of time.
NEVER clean your MFMA floor using scrubbing
machinery or power scrubbers that use water under pressure. Water is your
floor's worst enemy!
NEVER attempt to modify or repair your MFMA sports
floor without first consulting your MFMA contractor.
NEVER use household cleaning products or
procedures. They can be harmful to the floor finish and to the wood and may
also leave floors sticky or slippery, and potentially harmful to athletes. Your
MFMA finish manufacturer will recommend the proper cleaning and maintenance
materials for your MFMA sports floor.
