Case Study: A carpet directly glued down has several bubbles, and underneath is a white powder substance. How would a carpet inspector perform this inspection?
Carpet inspectors face many different challenges. They must figure out what causes the problems that clients report. One issue comes up more often than expected. Inspectors often encounter reports of a white, powdery substance underneath a carpet.
One cause of the white powder could be the deterioration of the carpet backing. Sometimes vinyl and other materials break down, and the result is a powder under the carpeting. Another cause could be alkaline salts coming up from the concrete slab underneath. A pH test evaluates this, as well as by checking the moisture content of the slab itself.
A third option might be that the clients have used a lot of powdered carpet cleaner or deodorizer over the years, but haven’t been able to thoroughly extract it. Either they are using the wrong kind of vacuum, or the machine isn’t powerful enough to do the job of getting the powder up. This means it has accumulated behind the carpet backing.
One final cause might be that the carpet adhesive has broken down. This could create a powder between the subfloor and the carpet backing. The carpet inspector needs to determine the origin of the powder. Then, they let their client know so that they can get started on a solution.
In my case I have a hand woven wool area directly on the hardwood floor and there was a large amount of fine grey powder under the rug

You should hire an inspector to determine the root cause. The causes could manufacturing or site conditions related.
Ok. I’m just relieved it’s not something I need to call the bug exterminator about. By in in
