I have a specification for a clear concrete sealer that is used to seal an existing concrete floor. (Ben Moore - SuperSpec 100% Acrylic Masonry Sealer' = 165 g/L VOC)
According to product info it
'Reduces the porosity of masonry surfaces' (sounds like a masonry sealer)
'Provides excellent surface adhesion' (sounds like a primer)
'Tintable' (sounds like a stain)
and of course - it'll go on the floor - as a 'coating' and therefore would not meet the 100 g/L VOC requirement.
the Rule 1113 definitions don't help much - any guidance on this would be appreciated.

I would call this a "sealer and undercoater" for 200 g/L.

It is up to the manufacturer to properly categorize the coating in compliance with SCAQMD Rule 1113. Unfortunately, manufacturers are living in the current iteration and there are some disconnects with credit referenced version which is now five rulemakings behind.
'Floor Coating' can be eliminated from the list as the definition covers opaque coatings and those generally not having concrete protection characteristics.
Absent definitive feedback from the manufacturer, I'd say Mara is on the right track.
As an FYI, the text of the Rule 1113 as it existed on January 1, 2004 is now in the credit resource section on USGBC's website. The CARB 2007 SCM can be used as a substitute as allowed in the October 1, 2013 interpretation utilizing its category definitions and limits. The SCM is more universal with manufacturers and is incorporated by reference in CalGreen, the IgCC, ICC-700 and the ASHRAE 189.1 update.
