Application Guidelines
- Surfaces must be fully dry, clean and free from dust, grease and all old sealant residue before starting
- Apply masking tape along joint edges for crisp lines; remove tape immediately after tooling, pulling away at a 45° angle
- Cut the nozzle to match joint width; apply with a standard sealant gun at steady, even pressure
- Smooth and finish within the first 5–7 minutes using a damp finger or suitable tool; marks will show once skinned over
- Keep dry throughout the full cure cycle (approx. 24 hours); extend for deeper beads
- Provide good ventilation during application and curing; leave windows open
- Not recommended for natural stone (marble, travertine) — acetoxy silicones may stain; use neutral‑cure Silicone N on such surfaces
Frequently Asked Questions
How does anthracite grey differ from black?
Anthracite grey is slightly lighter and softer than pure black; it blends more naturally with most modern window and door finishes without the stark contrast of true black.
When does it become water‑resistant?
Surface skins in 7 minutes; light contact after 1 hour; allow full 24‑hour cure before continuous water exposure.
Can it be used on natural stone?
No — the acetoxy system may stain or discolour porous stone such as marble and travertine; choose Soudal Silicone N neutral‑cure sealant instead.
Can it be painted over?
Silicone‑based products do not accept paint; match the shade directly or use a paintable acrylic sealant if colour adjustment is needed.
Are other colours available?
Yes — white, clear, black, brown and more; select the shade that matches your project.
