This is a one-part silicone sealant in a 310ml cartridge supplied in grey, intended for sealing external joints on site. The medium-modulus formulation suits typical movement in perimeter joints, expansion gaps, and glazing connections, supporting flexibility without compromising the seal.
Builders typically use this product for weatherproofing façade elements, cladding, and external window frames where a lasting, moisture-resistant barrier is required. Its working time allows for adjustment during installation, and the grey colour provides a professional, discreet finish against common substrates.
