All About the Wood Floor Moisture Problems
When you work to avoid wood floor moisture, there are several layers that could contribute to the moisture problems as what discussed as well by Todd Shupe LSU. In an effort to correctly install the wood flooring products, there are many steps that have to be done successfully as acclimating and installing the flooring product wouldn’t cut.
If for example that the wood floor is installed over concrete slab, this is regardless if there’s a separate subfloor, the moisture picture in concrete slab may bring some issues on the finished flooring. Say that the new slab is not thoroughly dried to finished specs, that moisture is going to wick through the surface of concrete and can cause anything from adhesive failure, wood warping or cupping.
Todd Shupe LSU discussed that if the older slab started developing moist patches or cracks, it is enough to work their way to surface and provide a way for the moisture to compromise the wood flooring. Even with usual vapor barrier, still moisture could be a problem if ever the slab hasn’t dried properly. For this, it is smart to understand the significance of wood floor moisture testing on concrete.
Concrete moisture conditions are reliable with relative humidity testing that is using situ problems. There are other testing methods that have been discontinued by several organizations such as poly film test or calcium chloride testing due to the reason that it was observed to be problematic before. Then again, there are other known meters including the surface concrete meters that can be pretty useful in taking relevant readings of slabs already in place to know what areas of it are requiring further testing of real quantitative moisture testing methods. Surface concrete meters don’t provide thorough picture of moisture conditions in the slab and for that, true quantitative testing should be done as what suggested by Todd Shupe LSU.
While you being the flooring contractor might not perform the RH testing, it does well to review the job specifications called for and to what the test results are shown before the start of installation. You may contest this by saying that wood floor moisture issues aren’t your responsibility but you should know that not doing your part can bring some unwanted issues. Todd Shupe LSU has been informing contractors of such to deal with such issue properly. In the finished flooring, improper moisture condition in the subfloor wood can cause real problems in the finished flooring.
