Thank you, especially for pointing this out:

> VOC is not about direct human toxicity

> "hard wax" oils people now seem to want to put on floors are also hardened with isocyanate

Sorry to go off topic but this caught my eye because I was recently recommended, by a very helpful local store, Rubio Monocat Oil Plus 2C to be used for DIY hardwood finishing. The employees at the store recommended this as a low-VOC option and the issue of PPE did not come up at all during the otherwise lengthy conversation.

The web site boasts 0% VOC, and when I search the manufacturer web site for "isocyanate" I get nothing.

Elsewhere I get this:

"Yes, our B-component has < 0.1% free isocyanates in it, but it’s not toxic. Not for the applicator of the product, nor for the people living in the room where the Accelerator, comp. B was used. That is a fact that has been confirmed by 2 independent established companies."

How would you go about making sure that this product is in fact safe to install for an amateur?
