GB-MT

Description

the SEALANT “GB-MT” is a white acrylic-based elastomeric sealant, designed to guarantee excellent resistance to fire and smoke. It has good permanent elasticity, allowing it to follow the structural movements of the substrate without cracking. The SEALANT “GB-MT” can be easily applied using a suitable gun, using shaped cardboard shields to obtain the minimum required sealing thickness. The outer surface can be levelled with a spatula or a damp sponge. The SEALANT “GB-MT” can be painted over.
