Sika Sikasil C — 300 ml Transparent Silicone Sealant
The Sika Sikasil C is a neutral-curing silicone sealant designed for professional and DIY applications. It provides reliable, flexible, and durable sealing across a wide range of building and construction joints.
Neutral-curing silicone formula — no acetic acid release, safe for most substrates
Transparent finish — remains discreet on all surfaces and colour-matched joints
300 ml cartridge format — ideal for precision application on small to medium joints
Excellent adhesion on common building materials including glass, ceramic, metal, and painted surfaces
What Sets Sikasil C Apart
Unlike acidic sealants, the neutral curing chemistry of Sikasil C prevents corrosion on metal and damage to sensitive surfaces such as marble, granite, and coated finishes. The transparent formulation ensures the sealant line stays visually unobtrusive after curing, making it suitable for visible joints in modern interiors and facades.
Ideal for
Professional tradespeople and DIY users working on building construction, renovation, and maintenance projects. Particularly suited for glazing work, sanitary installations, and exterior joint sealing where a neutral, colourless seal is required.
Application of Sikasil C
Clean the substrate thoroughly — remove dust, grease, and loose particles
Apply a continuous bead of sealant along the joint using a cartridge gun
Smooth the bead with a fingertip or tool to achieve the desired profile
Allow 24 hours for skin formation; full cure depends on joint depth and ambient conditions
