UniBond Anti-Mould Kitchen & Bathroom Sealant

UniBond Anti-Mould Kitchen & Bathroom Sealant provides a permanently flexible perimeter seal for exterior window and door frames.

Outstanding adhesion to wood, UPVC, polycarbonate and metal. It will not stain sensitive surfaces such as natural stone and marble.

It is suitable for Polycarbonate sheet, UPVC, metal, wooden window/door frames, exterior cladding, facia boards, soffits, draught proofing and insulating.

To gain a perfect seal, you must first ensure the area being sealed is clean, dry and free of old sealant, grease and dirt. Furthermore, to make sure that surfaces are as clean as possible, use a cloth damped with white spirit to remove remaining grease and dirt.

Using a sealant cartridge and gun: Cut the tip off the cartridge above the screw thread. Remove the nozzle cap and trim the nozzle at an angle of 45 degree to the desired joint width.

Screw the nozzle onto the cartridge and insert the cartridge into the gun. Apply by pulling the trigger. Storage: Store in a cool dry place and protect from frost and direct sunlight.

It provides 25 year guarantee. Direction to use - surfaces must be dry and clean of dirt, loose materials and old sealant. Prepare the cartridge and apply by pressing the trigger.

Smooth within 5 minutes to achieve a perfect finish. For the best results, use the UniBond Sealant Finishing Tool. Remove excess sealant before it dries with white spirit.

Protect the sealant from water and damp. Fully dry in 24-36 hours depending on bead size, temperature and humidity. Coverage approximately 11m with a 6mm bead.
