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

Incredible strength, this is one of the best PU sealer/adhesives you can get. I generally keep a tube in ready for using because it is so good, I used this tube on an old tractor which had perished and cracked, I pushed it into the cracks on the tread and the side walls ( I do not recommend doing this on car tyres, the tractor only runs at 10psi).I have moved over 100tons of rocks on hard ground and the sealer is still perfectly in tact.This sealer is similar to what the automotive industry uses to bond car panels on the vehicle and bond windscreens in and it sets like rubber with incredibly high adhesive properties, I tested it by sticking a strip of rubber on the trye in a place where it would get the most abuse and it stayed on in extreme digging conditions for a long time, I certainly didn't expect it to last more than 10 minutes but it lasted 2 days.I even used the spare sealer on some worn out gloves and they lasted better than when they were new!Any negative reviews are probably down to in proper application or silly things like receiving the incorrect colour as I have read!Important! This type of product will store for a long time if you use kitchen foil to seal the tube and store it in the fridge, I have done this for up to 12 months and still been able to use it.

Very similar to tiger seal, used this for bonding on a couple of side skirts.Easy to use, good adhesion and overall a decent quality gear. Just put on, put in place and tape to hold in place overnight if needed.Recommended!

Absolutely perfect for re-sticking my boot sole back onto my Dr Martin boots. After local cobblers failed to repair them, this product was just the job perfect repair and flexibility boots as good as new.

Make sure you have it in the right place becasue this stuff sticks ..... tought to get out of the tube but worth the effort.. great for sticking stuff to ABS car bumpers

I've bought quite a bit of this over the years. It's a great alternative to other similar products commonly used in automotive sealing and adhesive, but around 40% cheaper. It's of comparable quality, so I don't really see the point in spending on the names brands unless I'm working on something really special.

Bought this to fit a spoiler to my car we also stuck a piece of wood to a brick let it sit for 2 days fair to say the wood snapped and that wasn't with the grain it was against so alot tougher. As for my spoiler it isn't going anywhere and will be purchasing this again when I need it. It absolutely adheres to what ever it comes in contact with. Its superb!!!

This item doesn’t seem to hold up very well so I. Had to get some tiger seal

Really impressed. Half the price of my usual sealant and does a great job. Will buy more in future
