Hi there. We are in the middle of a renovation of our master bedroom and bath. We are using Farrow and Ball paint but looking for a really good no (or very low) VOC primer for walls, ceiling, and wood trim. Bathroom walls are new drywall and bedroom walls are skimcoat over plaster. Does anyone have thoughts or recommendations? FB primer is really expensive and seems to have a lot problems. Reviews for BM Natura are pretty bad, and there are only a few mixed reviews for the Zinnsser and Kilz no VOC. Beyond that I'm not finding much online. Any advice greatly appreciated!
