Why your cement DIY projects can pose serious health risks

Working with wet or dry cement can lead to serious health problems, like skin and respiratory issues, if the proper safety precautions are not followed.

A lot of people don't realize just how many household materials actually contain cement. It's quite different from concrete, and it's actually what holds together mortar, grout, plaster, and terrazzo. But no matter which material it's a part of, cement comes with some serious health risks. For starters, it's highly abrasive, and it pulls moisture out of anything it touches. Leave wet cement sitting on your skin too long, and you're looking at irritation, swelling, and, in more serious cases, severe burns.

Dry cement, isn't as harsh on skin, but the dust it releases is still harmful. If that dust mixes with sweat or damp clothing, it can also burn your skin. Breathing it in is just as concerning. It can irritate your nose and throat, make breathing harder, and cause issues such as mild eye redness and serious vision damage. If you're sensitive to skin and respiratory issues, cement work might be home DIY projects you should avoid.

Now, the tricky thing is not every health concern shows up right away. Some cement contains traces of a compound called hexavalent chromium, which can trigger allergic reactions in the skin or lungs. This means someone could work with cement for years without any issue, only to suddenly develop a rash, or even asthma-like symptoms such as wheezing and shortness of breath. Once that sensitivity develops, it only gets worse, sometimes turning into a permanent allergy to wet or dry cement. This is why it's important to avoid new DIYer mistakes and follow safety precautions when you're working on projects that involve cement.

Safety precautions to follow when working with cement

Before you buy quick-setting cement for an easy decor project, or that essential renovation, know that protecting yourself starts with the right gear. Skip the everyday garden gloves and grab a pair that's alkaline-resistant. When you put them on, ensure your sleeves cover the gloves, and your pants are equally tucked into your boots. You can even consider taping the top of your boots so there's no opening for cement to slip in. If you'll be standing in wet cement, wear boots tall enough that it can't slip in over the top. For your eyes, safety glasses with side shields are the bare minimum, while a mask rated P, N, or R 95, offers critical respiratory protection.

If you're taking on a DIY concrete project, consider buying pre-mixed concrete to reduce exposure to dry cement. Working somewhere with decent airflow also helps, and try to position yourself so the wind is blowing the dust away from you, not toward you. And, before you start, take off any accessories that could trap wet cement underneath.

Once you're finished for the day, proper clean up is essential. If your clothes get soaked with wet cement, get them off immediately. Further, avoid rinsing your hands in the same bucket you used to clean your tools, since that water's already contaminated. Should cement get on your skin, rinse it off under running water thoroughly. If there are any cuts, flush them out and cover them with a clean dressing. Worst-case scenario: seek medical attention if cement gets in your eyes or your skin keeps bothering you after rinsing.
