Why Choose This Product

The Bond It Multi-Mate Silicone Multi Purpose Sealant White 285ml combines CE-certified performance with genuine trade value. Its high-modulus formula provides a stronger, more durable seal than standard low-modulus alternatives, while the integrated fungicide keeps surfaces cleaner for longer in damp conditions. Flexibility lasting up to 20 years means fewer call-backs and less remedial work — a practical choice for both one-off DIY projects and high-volume trade use. Supplied in a standard EU3 cartridge compatible with all skeleton and trigger sealant guns.
