No, this silicone sealant is not designed to be painted over. It's best used as a decorative and protective finish in itself.
While it offers a waterproof seal, it's primarily formulated for builders' use on external perimeters and joints. For high-moisture areas like bathrooms and kitchens, a dedicated sanitary or anti-fungal silicone is generally recommended.
Curing time varies depending on bead size, temperature, and humidity. Typically, it becomes tack-free within 1-2 hours and fully cures in approximately 24 hours.
It adheres well to a wide range of surfaces including PVCu, wood, aluminium, steel, glass, concrete, brick, and most plastics without the need for a primer.
This product has low dirt pick-up, which helps it stay cleaner, but it does not contain specific anti-fungal or anti-mildew additives.
Yes, it is suitable for sealing expansion joints in soft metals due to its non-corrosive nature and flexibility.
Ensure the surface is completely clean, dry, and free from dust, grease, or old sealant. Reapply, ensuring good contact with the substrate.
Practice applying a consistent bead with a sealant gun. Ensure the nozzle is cut to the appropriate size for the gap. Use a tooling agent and spatula for a smooth finish immediately after application.
Ensure adequate ventilation and the correct temperature and humidity levels. Curing times can vary based on bead thickness and environmental conditions.
Ensure the cartridge has not been stored for excessively long periods in adverse conditions. Proper storage is key for optimal performance.
Setup: Ensure the application area is clean, dry, and free from dust, grease, and old sealant. Cut the nozzle to the desired bead size and load into a standard sealant gun. Apply a consistent bead of silicone along the joint or gap.
Compatibility: This silicone adheres well to a wide range of substrates including PVCu, painted and unpainted wood, aluminium, steel, glass, concrete, brick, and plastics. It is non-corrosive and suitable for use on soft metals. For best results on porous surfaces, a compatible primer might be considered, though it is often not required.
Care: Tool the silicone immediately after application using a damp tool or spatula. Clean excess uncured sealant with a damp cloth or appropriate solvent. Once cured, the sealant can be cut away if removal is necessary. For maintenance, simply wipe the surface with a damp cloth; avoid abrasive cleaners.
