Are Drywall Mud Fumes Toxic?

Drywall mud is a mixture of water, plaster, and other additives. When it is mixed and applied, it releases a fine mist of particles that can be breathed in. These particles can cause irritation to the lungs and eyes, and may also be toxic.

If you’ve ever worked as a drywall installer, you know that the process of installing drywall is quite messy. During the installation process, you often end up with a lot of dust and mud on your hands and clothing. And for many people, that’s when concerns about drywall mud fumes start to creep in – especially if you have asthma or another respiratory condition.

However, there are some important things you should know if this is your first time working with drywall. Let’s take a look at everything you need to know about drywall mud fumes and how they affect your health.

What is Drywall Mud?

Drywall mud is a paste-like substance used to fasten the drywall panels to the wood framing of a building’s walls. Drywall mud is applied to the back of the drywall panels and the wood framing before the panels are screwed into place. Drywall mud is composed of a variety of materials, including water, sand, paper, fiber, and additives such as gypsum and glue. Drywall mud is applied either from a bucket or a sprayer so that it adheres to both the drywall and the frame. A typical application of drywall mud covers about one square meter of wall, and a bucket of drywall mud contains enough substance for approximately six square meters of coverage.

How Are Drywall Fumes Made?

When you apply drywall mud, the water evaporates, leaving the sand and fiber behind. As the paper in the drywall mud ages, it breaks down into carbon dioxide and hydrogen sulfide. This is what you’re breathing in. When you apply drywall mud, you’re likely to get it on your skin and clothing as well. The chemical reaction that produces the gases occurs even if the mud is applied with a paint roller. So, the fumes are formed whether you’re applying the mud by hand or with a machine.

Is Drywall Mud Fumes Toxic?

Yes, drywall mud fumes are toxic. They contain carbon dioxide and hydrogen sulfide, both of which are toxic. Hydrogen sulfide, in particular, is toxic enough to be lethal in large amounts. But when you apply drywall mud, you should be careful to avoid getting it on your skin so that you don’t get a rash or other skin irritation. If you do get drywall mud on your skin, you should wash it off using lots of water as quickly as possible. If you leave any drywall mud on your skin for too long, you could end up with drywall rash or drywall dermatitis.

Should You Worry About Drywall Fume Toxicity?

Generally speaking, yes. When you’re working with drywall mud, you want to make sure to take measures to protect yourself from the toxic fumes. You should wear a respirator mask to keep the fumes out of your lungs and a disposable overalls suit to avoid getting it on your skin and clothes. One thing to keep in mind is that the toxicity of the fumes varies based on the type of drywall mud that you’re using. Generally, the fresher the mud, the more toxic it is. So, you want to make sure that the mud is fresh enough to adhere to the wall properly but not fresh enough to be too toxic to breathe.

How to Protect Yourself from Drywall Fume Toxicity

There are some important things you can do to protect yourself from the toxicity of drywall mud fumes. If you’re working with a partner, you and your partner should take turns applying the mud so that each of you gets a break from the fumes.

And if you’re doing the work alone, you should try to work as quickly as possible. The quicker you apply the mud, the less time you have to breathe in the fumes. You should also make sure to use fresh mud that is not too toxic.
