Aussie Shield 300 PLF

Aussie Shield 300 PLF

Aussie Shield 300 PLF is a permeable, liquid-applied flashing membrane based on advanced silyl-terminated polymer (STP) technology. This single-component, moisture-curing membrane creates a seamless, highly flexible barrier that seals rough openings, joints, and penetrations. It is designed to bond with most building substrates, providing robust air and water resistance while allowing moisture vapor to escape. Its solvent-free and isocyanate-free formulation makes it safe for both installers and the environment.

Where to Use
