Stone Sealers for those that are Sensitive to Chemicals

Frederick M. Hueston  StoneForensics.com

For individuals who are sensitive to chemicals, including those with multiple chemical sensitivities (MCS), choosing the right sealer for countertops is just as crucial as selecting the countertop material itself. Sealers are used to protect and enhance the appearance of natural stone and other surfaces, but some sealers can emit volatile organic compounds (VOCs) or other irritants that can trigger sensitivities. Here are some considerations and options for choosing sealers for sensitive people:

1. Low-VOC and Zero-VOC Sealers:

Look for sealers that are specifically labeled as “low-VOC” or “zero-VOC.” These products are formulated to emit minimal to no volatile organic compounds, reducing the likelihood of causing respiratory irritation or other sensitivities.

2. Water-Based Sealers:

Water-based sealers are generally considered more eco-friendly and less likely to emit strong odors or irritants. They tend to have lower VOC content compared to solvent-based sealers. When choosing a water-based sealer, ensure it is explicitly labeled as low-VOC or suitable for those with sensitivities.

3. Natural and Non-Toxic Ingredients:

Consider sealers made from natural and non-toxic ingredients. Some manufacturers offer eco-friendly and biodegradable sealers that prioritize safety and environmental sustainability. Look for products that explicitly list their ingredients and avoid those with chemical additives.

4. Test Before Application:

Before applying any sealer to a larger surface, it’s wise to perform a small-scale test in an inconspicuous area to ensure you don’t have adverse reactions to the product. This will also help you gauge whether the sealer emits any odors that could be problematic.

5. Seek Recommendations:

Consult with professionals who are experienced in working with individuals with chemical sensitivities, such as environmental health experts or contractors who specialize in green building practices. They may have insights into specific sealer brands that have worked well for sensitive individuals.

6. DIY Sealer Options:

If you’re comfortable with DIY projects, you might consider making your own sealer using natural ingredients like beeswax, mineral oil, or food-grade ingredients. These options can be less likely to trigger sensitivities, but it’s essential to test them first.

7. Communication with Manufacturers:

Don’t hesitate to contact the manufacturers of potential sealers to inquire about their products’ suitability for sensitive individuals. Ask about the specific VOC content, ingredients, and any potential off-gassing.

8. Professional Application:

When applying the sealer, it’s recommended to have proper ventilation and, if necessary, wear protective gear to minimize exposure to the sealer. Consider having a professional apply the sealer if you’re concerned about the application process.

Choosing the right sealer for sensitive individuals involves careful research, testing, and communication. Opt for sealers that are labeled as low-VOC, zero-VOC, or water-based, and consider natural and non-toxic options. Always prioritize your health and well-being, and consult with professionals if you’re unsure about the best choice for your specific sensitivities.
