What Seam Sealer Is

A seam sealer generally (in adhesives/sealants) is a brushable sealant used to seal joints, seams, and gaps especially in automotive, metalwork, and general assembly contexts. Brush-on seam sealers are often polyurethane or acrylic-based, remain flexible, are paintable, and provide water, dust and air sealing once cured.

Typical Uses

• Sealing panel joints and seams in automotive bodywork

• Closing gaps in metal assemblies or structural joints

• Waterproofing and dustproofing seams in fabrication

• Can be applied with a brush, trowel or other applicator

Typical Properties (general seam sealer traits)

• One-component no mixing required

• Flexible and elastic after cure

• Paintable with most automotive paints

• Good adhesion to metal and many other substrates

• Designed to prevent moisture ingress and corrosion
