Scope of Use

Designed for sealing of joints in wet and damp areas where resistance to the growth of fungus and mould is important.

  • Bonds to ceramics, glass, steel, aluminium, and most plastic and painted surfaces

Recommended Uses:

  • Kitchen and bathroom fixtures
  • Ceramic tile grouting
  • Glass, fibreglass and glazed ceramic tiles
  • Vitreous enamel and most laminated surfaces
Limitations on Use
  • Bostik Kitchen & Bathroom Silicone is not suitable for the following applications:
    • Potable water application e.g. water collection off a roof
    • Totally confined spaces as the sealant requires atmospheric humidity to cure. It will not cure where it does not have access to atmospheric humidity
    • Aquariums
    • Adhering mirrors
    • Structural glazing
    • Under water applications including swimming and spa pools
    • Below grade applications
    • All stone — staining may occur. Contact Bostik for recommendations
    • Trafficable areas
    • Polycarbonate sheeting
    • Sealant may discolour copper and brass
    • Where painting is required. If painting is required, the use of paintable Simson Sealants is recommended 
  • Do not clean or treat the silicone with materials, cleaning agents or solvents that may affect or discolour the silicone. This includes, but is not limited to, bleach containing cleaners, solvents and paint fumes. The silicone is especially vulnerable while curing.
  • Silicone sealants will tend to show a slight colour shift on ageing. This will not detract from the product performance.
