Both sides yes, but it is moisture, as in vapor, resistant. It is almost useless exposed to water. I would only use it in a bathroom for the ceiling or upper wall, no where near water. DensArmor Plus is a much better product for occasional exposure to water. Cement board is best for wet locations.
I’ve learned that it’s not recommended for ceilings, because it will sag a little when exposed to moisture. Straight from the manufacturer.
