Which air sealing product is suitable for use around water?

The most suitable air sealing product for use around water is silicone sealant. Silicone provides excellent waterproof properties and is highly effective in creating a long-lasting, flexible seal around sinks, bathtubs, and other areas exposed to moisture. Its ability to withstand water without breaking down makes it ideal for environments prone to dampness, unlike acrylic latex, which can degrade when in constant contact with water.

Acrylic latex, while useful for various sealing tasks, is not specifically designed for wet environments, as it can sometimes absorb moisture and lose adhesion over time. Foam insulation and expanding foam, while effective at sealing gaps and insulating, do not provide the necessary waterproofing and may degrade when continually exposed to water. Therefore, silicone sealant’s unique properties make it the optimal choice for applications involving water.
