The pin meter is not acceptable for testing concrete at all.
Pin moisture meter reading through existing laminate.
Most laminate manu s want a layer of thick visquine laid over the concrete and run up the walls a couple of inches.
These meters are less accurate than pin meters and may produce questionable moisture readings with low profile flooring therefore limit its use to flooring 3 4 or thicker.
Wood laminate subfloor moisture standards kronotex less that 14 on wood subfloors shaw 12 maximum on wood using a wood pin probe meter mannington columbia mohawk quickstep unilin each state that subfloor moisture content may not exceed 12.
Moisture content for wood.
Some ways to use a moisture meter with a reference scale include.
Step 2 is documenting your readings.
But with the moisture levels you have i would worry about the moisture damaging the walls if they are sheetrock.
It should be noted that readings above 27 nominal value of the fibre saturation point are indicative only.
In general a reading of 5 12 percent is optimal but a normal reading on a moisture meter depends on the material with drier ones like drywall needing lower moisture readings of around 5 7.
This is especially confusing where the meters scale incorporates colored zones green good or low yellow fair or moderate and red bad or high or colored lights as in the case.
Wood pin meter mode vs.
By documenting your moisture readings you now have a reference point to go back to should a problem happen.
Non destructive measurement mode the two main types of moisture meter for measuring moisture content in wood are the pin type meter.
Some meters use a 0 300 reference scale so readings taken on a reference scale often do not correlate with one another.
Measurement can be taken through the finish coating.
With all meters the readings would be quite low with a thick laminate which could lead an inexperienced user to conclude that there isnt much moisture present.
In many cases a moisture meter s reference scale will range from 0 100 but that reading should not be confused with a percentage.
Quick pass fail moisture.
Next the moisture meter is useful in verifying that water has been trapped within the laminate.
These tests simply indicate the presence of moisture or degree of saturation or resident static moisture level and use simple testing methods such as moisture meter surface probes.
The mrh iii gives moisture readings from 7 to 40.
The cc tests are high.
Without regard to the make or type of meter i will state that none give a reading that can be related to anything other than an arbitrary scale which meter manufacturers adopt as their standard for moisture level.
Moisture testing standards follow for several nalfa member companies.
We talked about taking moisture readings.
