(3 Tubes) PU18 Black Polyurethane Sealant Adhesive Strong Flexible for Construction, Auto and Marine applications. Non Shrinking High Grab Suitable for Expansion Joints . Paintable .

Great strong adhesive sealant! It applies smoothly, cures well, and stays flexible once set. Ideal for construction, automotive, and general repairs. The bond is solid and long-lasting—excellent value for a 3-tube pack.

This is really good stuff. Does an excellent job. Easy to apply and can even be done when it's raining.

The product is fully sealed in aluminium tube even to the point of having zeolite around the piston to ensure it remains dry. This fits in any skeleton sealant gun. The flexible nozzel is supplied with screw on reseal cap. The jet black sealant once set sets looks the same as when it comes out of the tube (and exactly as you leave it after any tooling). There is no shrinkage and once set the tough material has flexibility (feels like hard rubber). Having used many sealants over the years this is by far one of the very best and looking at it it should be very durable. Other colours are available therefore enabling many uses for this.

Brilliant sealant. Sticks well. Strong holding. Allow to fully set before overpainting. WEAR GLOVES!!! IT STAINS SKIN FOR DAYS SOLVENTS AND SOAPS WILL NOT REMOVE.

Excellent for protection.

does the job

I ordered 3 tubes of black, yet received grey. But it was too late to return as I opened one to use it urgently. I would say that the sealant is not as thick as some others, but it does the job.

great
