UniBond Weather Guard Extreme Repair Sealant Adhesive and Filler Cartridge is the ultimate tool for all DIY needs. With its patented FLEXTEC technology extreme repair is a sealant, grab and filler all-in-one, suitable for sealing joints, filling cracks and bonding most materials.

The high-performance formulation can be applied in any weather condition (even rain). So come rain or shine, it will guarantee you 35 years of strength and durability. It features all-weather bonding and sealing of frame, roof and guttering, UPVC double glazing, external cladding, delicate surfaces (such as mirrors, polystyrene and marble) and bedding compound

Remove the nozzle cap and trim the nozzle at an angle of 45 degrees to the desired joint width. Screw the nozzle onto the cartridge and insert the cartridge into the gun. Apply by pulling the trigger. Smooth within 5 minutes to achieve a perfect finish. It protects the sealant from water and damp.
