Video 20 – Kanare’s Summary
So, to wrap up, we know that relative humidity indicates the chemically active water that’s available to interact with adhesives and floor coverings.
In our experience over the last 15, 20 years making lots of measurements, thousands of measurements on many different floors, it really seems to be the most useful tool to understand the true moisture picture within a floor.
Adhesive and floor covering performance really does relate to relative humidity, as you saw, we can do tests scientifically, valid, accurate, useful tests in the laboratory that tell us how an adhesive and floor covering respond to different relative humidities. So that manufacturers can set-up this tiered systems and provide you with particular adhesives and floor coverings that will work under different moisture conditions.
We know that relative humidity can be measured usefully even when the building is not at service conditions. We will know in a fairly short time, we’ll have available for you some graphs and some tables, so you can convert relative humidity measurements made in the field under, whatever the temperature conditions happen to be, to the true service conditions of the floor coverings we’ll see. And that’s going to be great, because, it means we’ll be able to make measurements, early in life of construction and predict if the floor would be dry enough when it’s time to install the floor coverings or coatings.
