Application Guidelines

• Surfaces must be fully dry, clean, and free from dust, grease, and all traces of old sealant before starting
• Apply masking tape along joint edges for sharp, neat lines; remove tape immediately after finishing while the sealant is still wet
• Cut the cartridge nozzle to match the joint width; apply with a sealant gun at steady, consistent pressure
• Smooth and tool the bead within 5–10 minutes of application using a damp finger or suitable finishing tool
• Keep dry throughout the full cure cycle (approx. 24 hours); extend this period for thicker beads
• Provide good ventilation during application and curing; leave windows or doors open
• Clean and reseal the nozzle after use; store in a cool, dry place for future use

Frequently Asked Questions

Will the white shade turn yellow over time?
Its advanced formulation offers high resistance to UV and moisture; regular cleaning will preserve the original white finish for years.

Can it be applied over existing mouldy silicone?
No — all old sealant must be completely removed and the surface thoroughly cleaned; otherwise adhesion will be weak and early separation will occur.

When can it be exposed to water?
A surface skin forms in ~10 minutes; light cleaning is safe after 6 hours, but allow the full 24‑hour cure before continuous water contact.

What other surfaces does it bond to?
Direct, reliable adhesion to ceramic, porcelain, enamel, aluminium, stainless steel, painted wood, and rigid plastics — no primer required.

Is a clear version available?
Yes — the Silirub SC range is also available in Clear for glass and neutral‑finish applications.
