Sealing & Bonding Products

illbruck FA870

FA870 is a high-performance, one-component, neutral curing silicone with fungicide developed specifically for the sealing of natural stone. The non-staining formulation ensures long term elastic sealing of movement joints between granite, slate, terrazzo, porphyry, limestone, travertine, sandstone, quartzite, marble, etc., as well as concrete, ceramics, metals, glass, PVC and primed wood.

Packaging: 310ml cartridges
Colours: Available in 24 colours (see colour chart)

Surfaces must be clean, free from grease and must be stable and dry. Any previously applied sealant must be mechanically removed. A backing rod such as FGT BR135 is recommended beneath the joint to ensure the sealant is only bonded to two surfaces.

Please see data sheet for more information. Please do not hesitate to contact us for further information, pricing or to discuss your sealing & bonding requirements.
