Selleys White For Life Wet Area Waterproof Silicone Sealant 300g

Overview: Selleys White For Life Wet Area Waterproof Silicone Sealant is a premium, 100% silicone sealant designed to provide a long-lasting, waterproof, and mould-resistant seal in high-moisture areas such as bathrooms, kitchens, and laundries. Its advanced formulation ensures the sealant remains brilliant white over time, resisting yellowing, staining, and blackening.

Surface Preparation: Ensure all surfaces are clean, dry, and free from dirt, dust, oil, and loose materials. Clean the area with mineral turpentine and wipe dry with a clean cloth before application.

Application Instructions:

1. Cut the nozzle at a 45° angle to the desired bead size.​

2. Cut the cartridge tip and fit the nozzle.​

3. Place the cartridge into a caulking gun and apply steady pressure to ensure the sealant is pushed into the joint.​

4. Tool the sealant with a spatula dipped in detergent water within 5-10 minutes of application for a smooth finish.​

5. Clean up any excess sealant with mineral turpentine before it skins.​

6. Allow the sealant to cure fully, which typically takes 72 hours.​

Coverage: The coverage depends on the joint size; for example, a 5mm x 5mm joint will yield approximately 12 linear meters per 300g cartridge.

Drying Time: The sealant skins in about 10 minutes and cures fully in 72 hours.

Clean-Up: Uncured sealant can be removed with mineral turpentine. Once cured, the sealant is extremely difficult to remove and must be abraded or trimmed with a knife.
