This type of material is most appropriate for southern climates where keeping humid outdoor air from entering the building cavities is critical during the cooling season. Sherwin williams has a moisture vapor barrier latex paint b72w00001 that comes in at less than 1 perm.

Benjamin moore has a super spec primer k206 00 that is a latex paint and comes in at less than 0 5 perms. Water vapor barrier paint is often applied to drywall walls and ceilings in attics where warm air tends to rise. Ccw 705 air vapor barrier strips datasheet sds detail self adhering flashing for detailing ccw 705 and barriseal systems. In 2017 dalia kaminski of montreal needed some and has shared with me some very thorough research.

Is more of a solution for walls rather than ceilings to prevent the indoor vapour drive during hot humid weather. Moisture vapor barrier primer finish interior latex is a coating designed to reduce the loss of moisture through walls and ceilings. An air barrier vapor diffusion retarder attempts to accomplish water vapor diffusion and air movement control with one material. Without water vapor barrier paint the warm air would release its water inside of the walls and ceilings where the water would saturate the insulation and framing.
