FAQ
How long does the mould resistance last?
The formula contains a long-lasting mould inhibitor effective under normal use conditions. Maintaining good ventilation in wet areas will help extend the mould-resistant performance.
Can this sealant be used on natural stone?
No. Natural stone is porous and the sealant may cause staining. Please contact us for alternative products suitable for natural stone joints.
How long before the sealed joint can be exposed to water?
Skin time is approximately 5-10 minutes, but deep curing progresses at ~3-4mm per 24 hours. Wait until the sealant is fully cured before water exposure — deeper joints may require several days.
