Features and benefits Polyseal PS GG is specifically designed to be used as a watertight sealfor moderate movement and control joints. Properties Highly resilient with excellent recovery characteristics Provides permanent and uniform watertight seal Non-staining Excellent resistance to fatigue and stays flexible throughout its service life – won’t become brittle, caulk or crack due to ultra violet exposure Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes Excellent adhesion to most common building substrates Description POLYBIT® Polyseal PS GG is a non slumping two component, chemically curing polysulphide joint sealant. It is based on a liquid polysulphide polymer which when mixed with the hardener, cures to form a tough, flexible and non staining rubber like seal.
