AFM Safecoat does not have permeability ratings for their products. This is an acrylic paint that breathes slightly, but not like mineral-based Silacote or Clay Paint (neither are used for floors).
If you are using this on concrete with moisture issues, seal the concrete first with GBS Penetrating Concrete Sealer and then apply the AFM Safecoat Concrete Floor Paint several days after it fully dries.
If there is no evidence of moisture intrusion (e.g. efflorescence) and you've lived in this home through many flood periods over the years without issue, we recommend skipping the sealer, and simply applying 2-3 coats of paint.
