Mixing tile grout, like many other construction or home improvement activities, can expose you to dust and chemicals that may not be good for your lungs over time. While occasional exposure might not cause immediate harm, prolonged or repeated exposure without proper safety precautions can lead to respiratory issues.
Dust particles from grout can be irritating, and some grout formulations may contain substances that can be harmful if inhaled. It’s important to use protective gear such as masks, goggles, and to work in well-ventilated areas to minimize exposure. If you're mixing grout regularly, following safety guidelines and using appropriate protective equipment is crucial for long-term health.
