Wood Floor Cupping Causes & Fixing


What is cupping? Cupping is usually the
first obvious sign that a floor is being affected by moisture in its environment.
Any hardwood floor will naturally expand when it’s exposed to moisture. When only
one side of a plank is exposed, just that side will expand causing the whole board
to warp away from the damp side. This makes the plank edges curl up
resulting in an overall wavy appearance. This can happen due to seasonal changes,
like during the summertime, when humidity levels rise. In this instance the
expansion tends to correct itself naturally when the seasons change and
humidity falls. The most common causes are wet mopping, which should not be done
on any hardwood floor, and when the relative humidity in a home is not kept
within a 20% range. Cupping can also occur due to faulty
plumbing, bad ventilation, and a variety of other circumstances all having to do
with excessive moisture in the home. How to treat cupping. In some cases a cupped
floor can straighten out naturally over time on its own, but the key here is
first determining all potential sources of moisture and acting quickly to treat
them before the flooring becomes permanently damaged. Until this occurs a
cupped floor cannot be repaired. Once you have located and eliminated any trouble
spots and controlled your home’s humidity, erify that the underlying
subfloor is dry by taking readings with a moisture reader. This may take weeks,
months or even an entire heating season. It’s a good idea to take moisture
readings at different levels in the flooring. If there’s a difference of 1
percent or more between the top and bottom of the boards they’re probably
not done drying. If your flooring does not return to an acceptable state, your
home likely has an underlying moisture issue and requires closer inspection by
a professional certified by the National Wood Flooring Association or NWFA . So
just to recap, to avoid cupping you’ll want to stay away from wet mopping your
floor. Keep your home’s relative humidity within a 20% range.
Avoid excessive moisture, and use the recommended moisture barriers when
installing. For more information contact the Cali Bamboo customer support team at
