FAQs
Can this sealant be used in a bathroom or kitchen?
Yes, it is suitable for internal applications and contains a fungicide to help retard mould growth, making it a good choice for bathrooms and kitchens. However, it is not designed for constant immersion in water.
How long does it take to fully cure?
While it can be painted within 1 hour, full curing can take 24-48 hours depending on application thickness and environmental conditions (temperature and humidity). Ensure it stays dry for at least 5 hours after application.
Can I use this sealant outdoors?
Yes, it is suitable for exterior use. However, it must be applied in good, dry weather conditions and must remain dry for at least 5 hours after application.
What surfaces does it adhere to?
It adheres well to most common building materials including plaster, brickwork, concrete, wood, metal, PVC, and painted surfaces, often without the need for a primer.
Can I paint over the sealant?
Yes, the sealant can be painted over with most water-based and synthetic paints within 1 hour of application. It is specifically formulated to prevent craze cracking of the paint.
What is the movement accommodation of this sealant?
It has a high joint movement capability of up to 12.5%, which is nearly double that of standard caulks, allowing it to accommodate significant expansion and contraction.
How do I clean up excess sealant?
Uncured sealant and tools can be cleaned up easily with water. Cured sealant will need to be removed mechanically or with a suitable sealant remover.
Troubleshooting
Sealant is not sticking to the surface.
Ensure the surface is clean, dry, and free from dust, grease, or contaminants. For certain challenging surfaces, a primer might be beneficial, although not typically required.
Sealant is cracking after painting.
This product is formulated to prevent craze cracking. Ensure you are painting within the recommended 1-hour window and using compatible paint types. If cracking persists, the joint may be exceeding the 12.5% movement accommodation.
Sealant remains tacky after application.
Ensure the sealant was applied in a single, continuous bead and was smoothed properly. Avoid applying in excessively humid conditions or temperatures outside the recommended range. Allow adequate drying time; tackiness may be normal before full cure.
Difficulty extruding sealant from the cartridge.
Check that the nozzle is cut to an appropriate size and that the inner seal of the cartridge has been fully punctured. Ensure the skeleton gun is functioning correctly.
