Waterproofing Capabilities

Both Lifeseal and Life Caulk offer impressive waterproofing capabilities, but Lifeseal is designed explicitly for below-waterline use in marine environments, giving it an edge in this aspect.

UV Resistance

Lifeseal and Life Caulk are UV resistant, ensuring their longevity and performance even when exposed to sunlight for prolonged periods.

Flexibility and Movement

Lifeseal and Life Caulk are formulated to be flexible, accommodating structural movements in the materials they are applied to.

Adhesion Strength

Both sealants provide strong adhesion to various surfaces, ensuring a secure and durable bond.

Ease of Application

Life Caulk may be easier to apply due to its versatile nature and suitability for various projects. However, proper surface preparation is crucial for both sealants.

Longevity and Durability

Lifeseal’s specialized marine formulation gives it a slight advantage in longevity and durability, especially in below-waterline applications.

Application Area

When deciding between Lifeseal and Life Caulk, the primary consideration is the intended application area. If you require a sealant for marine purposes such as boat repair, sealing decks, or bonding fiberglass components, Lifeseal is the superior choice. Its robust marine-specific properties make it the go-to option for projects exposed to saltwater and extreme weather conditions.

Life Caulk offers excellent versatility and strong adhesion for general-purpose sealing in marine and non-marine settings. It’s suitable for sealing joints on boats, RVs, homes, and other structures. Additionally, Life Caulk’s ability to bond with various substrates makes it an excellent all-around option for interior and exterior applications.
