We were asked by a contractor about a project where the milan wall (structural soil estabilization) is having some water filtrations. The product will be applied on a milan wall (concrete wall) that had some problems in a few portions of it showing "poor" concrete, when you scratch it it pulverizes, that is why they are having filtrations. What would be the allowable voc content for the product they are using to seal the filtrations? We believe architectural porous with a limit of 775 gr/L of VOC would be appropriate. Any comments would be appreciated.

I believe you are referencing SCAQMD 1168 - Sealant Primers. I would think that your product would be submitted under SCAQMD 1113 Waterproofing Concrete/Masonry Sealers - max 400g/l

Thanks John, A few days ago we received this answer from GBCI: "The architectural porous category seems reasonable for the described application. Please keep in mind that if anywhere on the container of any sealer or on any sticker or label affixed thereto, or in any sales or advertising literature, any representation is made that the sealer may be used as, or is suitable for use as, a sealer for which a lower VOC standard is specified in the table then the lowest VOC standard shall apply." And yes you are right, it will be considered at 400 we believe.
