FAQs about IEQc4.2 :

How should graphic arts paint or coatings be categorized?

The standards referenced for this credit have been updated since those listed in the LEED Reference Guide – does our project need to follow the latest SCAQMD Rules and Green Seal editions, or the ones listed in the reference guide?

How should handheld aerosol spray paints be handled?

What are the VOC limits for primers? They seem to be listed in both GS-11 and SCAQMD Rule 1113.

Hi all We attempt to use a hardwax for our hardwood floors in our project. Does this simply goes under "floor coatings"? It's hard to find hardwax with as low VOC-content as 100g/l and I don't think there are any at the swedish market (from what I can see from a little bit of researching), though we usually have really good products with low VOC. Under what product cathagory would you say hardwax for hardwood floors belongs to?

Hej Mathilda, That is a tricky one. I would classify it as a clear wood finish varnish as floor coating is described in Rule 1113 as an opaque coating for wood flooring. Hard flooring wax are usually clear and semi-transparent. Although you could argue it doesn't really fit into a varnish. As wax is not as durable as a varnish but then it definitely is not a lacquer. I think the best bet is clear wood finish varnish at a VOC limit of 350 g/l. Would be interested to see others perspective..

I would agree - when I used to use wax oh my hard wood floors home it was specifically in place of varnish. That was back when there weren't any low VOC varnish options and wax was a better health choice. For LEED you would want to indicate that the wax is serving the function of varnish (assuming that's true in your case), though there's no guaranty as to what their response will be.
