Stonesil is ideal for:
Sealing joints in premier bathrooms & kitchens.
Glass to glass joints.
Sealing glass to metal.
Expansion joints in brickwork/stonework.
The minimum joint size suggested is 5mm x 5mm for internal use and external use 10mm x 8 mm (width x depth). Maximum recommend width of the joint is 30mm x 30mm, but the joint depth should be roughly half the joint width for the ideal seal.
After applying the sealant, it can be smoothed in the joint with water or with a neutral, non-staining water-based smoothing agent and a suitable tool (e.g., Bond-It Applicator Kit). Smoothing the sealant isn’t just recommended for aesthetic reasons, but it will assist in the bonding of the sealant to the substrate.
