As you are trying to prevent wood floor moisture, there are various layers of it that are causing moisture problems as what talked about 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.
For wood floor that’s installed over concrete slab whether it includes separate subfloor or not, the moisture picture in concrete slab could bring ramifications for finished flooring. It is imperative that the slab is completely dried to be able to finish the specifications or else the moisture will keep causing problems on the concrete surface that can cause wood warping, cupping or even adhesive failure.
As a matter of fact, Todd Shupe LSU discussed at the same time that moist patches or cracks can develop in older slab which is more than enough to work its way up to the surface causing moisture that will later compromise wood flooring. Even with usual vapor barrier, still moisture could be a problem if ever the slab hasn’t dried properly. For this reason, it pays to understand the importance of wood floor moisture testing on concrete.
Concrete moisture conditions are actually dependable with relative humidity testing that utilizes 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. There are other varieties of meters such as surface concrete meters that might be useful at times in taking relative readings in current slabs to be able to figure out areas for further testing with the real quantitative moisture testing approaches. Todd Shupe LSU proposed that there has to be a true quantitative testing that ought to be done since surface concrete meters aren’t able to provide a clearer picture of moisture condition in slabs.
For a flooring contractor, not most will likely perform RH testing but it should be as it does so well in reviewing job specifications and show test results which are imperative before the installation begins. 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.
Whether you believe it or not, Todd Shupe LSU has got the relevant information for this particular subject which will significantly expand your knowledge.
