Is There Special Drywall For Basements? Do I Need Moisture Resistant Drywall In The Basement? Should You Use Waterproof Drywall For A Basement? Should You Use Purple Drywall In The Basement? What Thickness Of Drywall Should I Use For The Basement? Do You Use The Same Drywall For The Basement Ceiling? Conclusion The best course of action is to get drywall that is resistant to mold and moisture if you’re finishing a basement with it. This is due to the fact that basements are (at least partially) underground and hence more damp.

You have a perfect environment for mold growth when you combine this with the frequent flooding they experience.
You can use a normal inch-thick piece of drywall for the walls and an inch-thick piece for the ceilings, depending on size.

Whomever you contact will give you a different response regarding the best kind of drywall to utilize for your basement. In general, you should utilize drywall that is resistant to mold or moisture if your basement experiences high humidity or moisture levels.

One business, Toughrock , produces drywall basement boards that are only meant to be used in basements. This board resists mold growth and moisture.

DOES THE BASEMENT NEED MOISTURE-RESISTANT DRYWALL? Use moisture-resistant drywall if there are any moisture issues in your basement. Greenboard is a common name for moisture-resistant drywall, which has a stronger exterior covering preventing water absorption.

On the other hand, regular drywall is porous and will absorb water. This means that there is a chance of mold or mildew growth whenever ordinary drywall comes into touch with moisture.

SHOULD WATERPROOF DRYWALL BE USED IN A BASEMENT? Purple drywall is the most waterproof of all, while green drywall provides some moisture protection. If your basement has ever flooded or you’ve seen any dampness on the walls, waterproof drywall is great.

DOES THE BASEMENT NEED PURPLE DRYWALL? It’s not a bad idea to utilize purple drywall in your basement. Mold, mildew, and moisture can’t grow on purple drywall.

Additionally, because basements frequently have moisture issues, this drywall can aid in preventing the growth of mold or mildew on the wall.

WHICH DRYWALL THICKNESS SHOULD I USE FOR THE BASEMENT? Basement walls should be lined with inch-thick drywall. If your basement is dry, you can use regular drywall, but mold- and moisture-resistant choices are wiser purchases if your basement tends to become wet.


Although the walls and basement ceiling can both be made of the same thickness of drywall, most experts advise using an inch-thick sheet for ceilings. This is because inch drywall is far less prone than conventional inch drywall to sag between joists.

You can substitute regular drywall with moisture-resistant drywall on the ceiling if your basement stays relatively dry. Just make sure to use mold-resistant paint to cover the ceiling.

CONCLUSION Use inch-thick gypsum panels on the walls and inch-thick sheets on the ceiling while drywalling your basement. Use drywall that is water- or mildew-resistant if your basement is susceptible to moisture, which most basements are.

Although waterproof or moisture-resistant drywall is more expensive, it is less likely to mildew or require replacement in the future.
