Moisture and Mold-Resistant Drywall, explained in plain English
Standard drywall has a paper face that soaks up water and feeds mold. Moisture-resistant board, often green or purple, uses treated paper or a glass-mat face that holds up better in humidity. It is not waterproof. Showers and tub surrounds still need a waterproof layer, like cement board or a membrane, under the tile.
We use it on walls and ceilings in bathrooms, laundry rooms, utility closets and kitchens near sinks. Seams get taped and coated like any other board. The finish gets a mold-resistant primer and bathroom-rated paint.
What to think about before you start
- Moisture-resistant board is not a substitute for tile backer board inside a shower.
- Exhaust fans matter more than board. A fan that vents outside keeps moisture from building.
- Ask for a bathroom-rated primer and paint, with semi-gloss or satin sheen.
- Costs go up because of board price, not because of labor.
What it costs around Gainesville

How it goes in Gainesville
Humidity in North Central Florida runs high for much of the year. The EPA suggests keeping indoor humidity between 30 and 50 percent, which is a tall order in a Gainesville summer without good air conditioning and a working bathroom fan. The right board gives a bathroom wall a better chance.
How the job goes, step by step
- Check the framing and the source of moisture.
- Hang moisture-resistant board, leaving a gap at the bottom.
- Tape and coat seams.
- Prime with mold-resistant primer.
- Finish with bathroom-rated paint.
