Finish
Ambering
Urethane oil finishes (the type most commonly specified
for maple basketball, multipurpose and stage floors) as a group have
a tendency
to amber over time. The timing and degree of the ambering
vary by product, but typically the greatest color change in the finish
takes
place between the sixth month and the end of the first
full year of service.
In a repair situation, replacement boards will
appear
generally lighter in color than surrounding existing
boards due to the ambering affect of the existing
oil finish. The degree of variance is a function of
the age and number of coats of finish on the original
flooring. Color variations in the finish should be
expected on a repaired floor immediately after repairs are completed.
Most repair areas begin to blend in with surrounding
flooring after several months and over time become
imperceptible to the untrained eye.
MFMA recommends
contacting your finish manufacturer(s)
regarding the performance history of the specific
product(s) installed. As a rule MFMA does not recommend
tinting a repaired area to match existing floor coloring,
and does not recommend staining maple flooring under
any circumstances.
If you have additional questions, please contact
MFMA's Technical Director at 847-480-9138.
