Ensure all surfaces are clean, dry and free from grease or any contaminants that may hinder adhesion. For best results on movement joints, Bond It EXPANDING FOAM is recommended as a backing material, or a suitable backing tape or rod.


All surfaces must be clean, dry and dust and grease-free. Porous materials should be primed for optimum adhesion. When sealing deep joints use foam backer rods to minimise wastage. Cut the tip of the cartridge, screw on nozzle and cut at an angle of 45°. Apply at temperatures between +5°C and +45°C using a standard sealant gun. Tool the sealant using the appropriate shaped tooling aid - DO NOT USE A WETTED FINGER. Note: risk of yellowing in low UV light situations.


Not suitable for use with aquaria. Not suitable for use on bitumen or asphalt. Over-painting is not recommended. Substrates like marble, sandstone and similarly porous surfaces can show a discolouration around the sealant edges.
