Mapei Mapesil BM Silicone for Metal Work Grey Box 12 X 310ML

Mapesil BM is a solvent-free, neutral silicone sealant with a low modulus of elasticity, specific for sealing fillet joints between tinwork accessories and layers of waterproofing material.
It is particularly recommended for metals normally used on roofs and flat roofs such as steel, zinc and prepainted sheet, anodised and pre-painted aluminium and copper.
The chemical characteristics of the product also make it perfectly suitable for absorbent materials such as concrete, cellular concrete, brickwork, varnished and lacquered wood and various compact, non-absorbent materials such as glass, ceramic, clinker, enamelled surfaces, water and solvent-based paint and plastics such as polycarbonate:
Thanks to its broad spectrum of adhesion and low modulus of elasticity, Mapesil BM is also suitable for sealing fillet joints in tinwork accessories such as:
▪ Downpipes
▪ Guttering
▪ Flashing
▪ Metal flat roofs
▪ Corner guards
▪ Heads of rivets and fasteners
