SPC flooring, also known as stone plastic composite flooring, is a waterproof flooring option that is growing in popularity.
However, it is still important to ensure that the moisture content of the subfloor is within an acceptable range before installing SPC flooring.
The acceptable moisture reading for a concrete subfloor before installing SPC flooring is between **5% and 12%**.
If the moisture content of the subfloor is too high, the SPC flooring can buckle, warp, or delaminate.
If the moisture content is too low, the SPC flooring can become brittle and crack.
Moisture readings can be measured using a moisture meter.
There are two types of moisture meters: pin-type and non-pin-type.
* Pin-type moisture meters measure the electrical resistance of the wood to determine its moisture content.
* Non-pin-type moisture meters measure the dielectric constant of the wood to determine its moisture content.
Once you have a moisture meter, you can follow these steps to measure the moisture content of your subfloor:
1. Turn on the moisture meter and calibrate it according to the manufacturer’s instructions.
2. Place the moisture meter on the subfloor in several different locations.
3. Record the moisture readings.
4. Compare the moisture readings to the acceptable range listed above.
If the moisture readings are outside of the acceptable range, you should take steps to correct the problem before installing SPC flooring.
