Flooring Moisture And Quality Flooring
A good flooring moisture barrier is the key to quality and high-performance flooring. This is particularly pertinent when a resin surface is installed. That process can be severely hampered if the substrate beneath the already existing surface is still damp. In such cases, the obvious solution would be to break and replace the substrate and risk adding a lot more time and cost. But a moisture barrier can the salvation. It may be in the form of a liquid solution applied to a slab as a simple alternative to ripping off the old surface.
It is essential to be precise about flooring moisture. One most common method to measure it is the calcium carbide test. It involves taking core samples from a concrete floor which will be crushed and mixed with calcium carbide. The whole process takes a few minutes and is considered to a very accurate moisture reading method.
Knowing the accurate substrate moisture reading is essential for the long-term performance of a resin floor. The concrete and the screeds, both of which exceed the 4% moisture level, may result in the resin floor to be de-bonded or suffer osmosis.
A lot of manufacturers have a solution to eliminate such issues, like a guaranteed temporary moisture barrier that can also serve as a self-smoothing floor screed. The systems can be of three parts, and epoxy-modified, and comprising a moisture-tolerant primer. This primer will allow moisture to pass through the substrate to the temporary moisture barrier that scavenges the excess moisture. All of this will result in lowering the percentage to <4% by weight and will leave a resin-ready surface.
It is economical, fast and easy to apply. The sheer genius of a good moisture barrier lays in its superb ability to remain liquid resistant while staying permeable to water vapour.
