It seems like ceramic tile grout sealer should be considered as a "Waterproofing Concrete/Masonry Sealer" with a VOC limit of 400g/L The grout is a cement product. Would not want to find out after submittal to GBCI that they consider it under "Sealers and Undercoaters" with a VOC limit of 200 g/L. Has anyone had experience submitting this as a "Waterproofing Concrete/Masonry Sealer"?

Eric,
I wouldn't know for sure, but since grout is not a Division 4 product, I would not consider it a "waterproofing concrete/masonry sealer". Good Luck
