expands to fill, seal and insulate gaps & cracks inside or out up to 3 inches. It is a polymer foam based on

purified & concentrated ingredients that deliver premium durability. It is easy to use and apply with its

attached straw applicator and provides a quick durable seal from the elements. Use for filling larger gaps

and cracks around wiring and plumbing penetrations, HVAC ductwork, basement and crawlspace drafts,

sill plate & rim joists, attic hatches, under baseboards, gas line penetrations and outside water faucets.

Available As:

• High Density Foam – Uniform cell structure seal out air, moisture, and pests

• Flexibility – High Flexibility withstands building material movement

• UV resistance – High resistance to the elements without becoming brittle

• Strong adhesion – Bonds to most building materials; wood, metal, stone, brick, PVC

• Fills gaps & cracks up to 3”

• Bright white color

• Sandable & Paintable

Loctite TITEFOAM Big Gaps is suitable for interior and exterior projects. It has excellent adhesion to most building materials including wood,

• Despite significantly higher UV resistance, it is still recommended to protect the foam from UV radiation. Exposed foam should be

coated with a protective covering or coating.

• Do not store product on its side

• Does not bond polyethylene, polytetrafluoroethylene (PTFE)/Teflon® or siliconized surfaces

• For cold weather application, product should be stored at room temperature at least 12 hours before application

• In dry conditions, it is recommended to fill gaps in several layers by application of smaller foam strings (up to 3 inches thickness)

• Certain materials such as rubbers and plastics may have bonding difficulties. Test before use.

• Flexible sheet goods

A 340g (12 fl. oz.) can will extrude a 3/8” bead approximately 134.0 ft. (41.1 m).
