For perimeter sealing of external wood, aluminium and uPVC door and window frames and for weather sealing and flexible jointing of infill panels. Can also be used on concrete, plaster and mortar. Note: Not suitable for use with aquaria or for use on bitumen or asphalt. This product cannot be over-painted. Risk of yellowing in low UV light situations (e.g. if used indoors) whilst curing. The sealant may crack if exposed to movement before it is suitably cured, therefore joints should be protected from the movement for at least 3 hours after application.
While WP70 is suitable for sealing windows and doors in most circumstances its flexibility range is 12.5% and as such joints where more extreme movement is expected may be better sealed using the Bond it WP100 premium silicone offering 25% flexibility.
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.
How To Use
- 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 45degrees.
- Apply at temperatures between +5C and +45C using a standard sealant gun.
- Tool the sealant using the appropriately shaped tooling aid – DO NOT USE A WETTED FINGER.
Not suitable for use with aquariums. Not suitable for use on bitumen or asphalt. Over-painting is not recommended.
Substrates like marble, sandstone and similar porous surfaces can show a discolouration around the sealant

doors in most circumstances its flexibility range is 12.5% and as such joints where more extreme movement is expected may be better sealed using the Bond It WP100 premium silicone offering 25% flexibility.
