Frequently Asked Questions
Can I paint over this silicone?
No – it is not paintable. If you need to paint the joint, use a decorators caulk instead.
Is it suitable for natural stone?
No. Acetoxy silicones can stain marble, granite and other natural stone; use a neutral-cure silicone there.
How long before it can get wet?
It skins in about 20 minutes and cures at roughly 2 mm per 24 hours, so allow at least 24 hours before heavy water contact on a standard bead.
Will it work on PVC or concrete?
The manufacturer advises it is not suitable for PE, PP, PTFE, PVC, concrete or bitumen – do a test first or choose a neutral-cure sealant.
