All About the Wood Floor Moisture Problems
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.
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 also said that if old slab begins to develop either moist patches or cracks, it’s more than enough to work its way up to the surface and provide a way for moisture to 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. Other varieties of meters similar to surface concrete meters may sometimes be useful to take relative readings in the existing slabs to determine most likely areas for more testing with real quantitative moisture testing methods. Surface concrete meters is not providing a thorough picture of the slab’s moisture condition and with that, true quantitative testing must be done as what proposed by Todd Shupe LSU.
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. Wood floor moisture problems in concrete slab might not be your ultimate responsibility but leaving this unchecked will become your problem in the future. This is why Todd Shupe LSU informs contractor to always deal with this issue professionally. Incorrect moisture condition in wooden subfloor can lead to moisture related issues in finished floor.
