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

So versatile. I love it. I'm sure I use it on repairs it's not meant for, but it manages just about everything well. Usually I use it on my pond pipework as it's fish safe and super strong but the other day I even used it on a friend's hot tub that had a small hole in the blow up section. It repaired even that.Easy to use but very messy. Use petrol on a cloth to get it off your hands.It's not just water resistant, it really is waterproof. I haven't found anything it won't seal.

Great value and really good product used on flooring

I liked that it worked for my repair of washing machine door seal and the washing machine was usable by next day.I wish there was some way of stopping the rest of the tube from hardening once started.

As good as sikaflex and tiger seal in my opinion

Sticky, easy to spread, proper sealant.Much better than the other brands. A bit more pricey but that's quality.

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.

Absolutely brilliant stuff. Cheaper than sikaflex and does exact job as it says. I used it all over my van by sealing trims to the body, making seal on side marker lights, used between rear wheel arches and van body to bond together to stop water coming inside the van. Very good stuff and makes it hard rubber kind of material after use. Going to buy more for my conversion.

Great stuff, as everyone has said, but it is difficult to squeeze out of the tube, so pop it into the oven for 10 minutes at approximately 70 degrees C, and it flows out so easily, you could even use your little finger to pull the trigger.
