Polysulphide Sealants offer a versatile sealing solution provided in two variants:- Pouring Grade (PG) & Gun Grade (GG), both based on a liquid polysulphide polymer. These sealants exhibit strong adhesion properties to a wide range of common building substrates. They are highly recommended for effectively sealing horizontal structural expansion joints in various civil engineering structures, including building superstructures, subways, basements, floors and reservoirs.
