Sealant Product Guidance

Use the red-to-green product guidance below to select safer product types by avoiding those in red and preferring yellow and green, which are safer for occupants, fenceline communities, and workers.

When choosing a sealant product:

• Prefer caulk-type sealants to spray foam sealants.
• If foam sealing products are needed, prefer those that are pre-formed, like foam sealant tape.
• For a multi-purpose sealant, look for acrylic, latex, or siliconized latex sealants with very low VOCs (≤ 25 grams per liter).
• Avoid silicone, polyurethane, and hybrid/modified polymer sealants when possible.
• Avoid mold and mildew-resistant products unless necessary.
