In reference to the addendum for Table 1 IEQc4.2 Applicable VOC Limits has there been any clarification as to where concrete block fillers fall in the SCAQMD Rule 1113, 2004? I would identify concrete block fillers as a "sealer and undercoater", or should I be conservative and identify it as a "interior flat primer?"

I have not seen or heard anything on where concrete block filler would fall, but I would classify these as a primer. This is due to the fact that 'sealer' means to me that you have created something that is somewhat impenetrable and 'primer' means to me that you are preparing something. I believe most concrete block fillers are preparing the wall for something.

Please allow me to correct myself Dan - you are correct, per the November 2010 addenda Block Filler should be classified as you asked as a sealer/undercoater. Again, my apologies for this oversight on my part.
