An excellent sealer adhesive.
A great sealer adhesive .Used in a varity of situations for sealing around upvc widow frames a wooden garage door frame and some cracks on some fence posts.It worked well in all cases. The material flows easily and the colour is a dark brown

Very strong and weather resistant
Excellent stuff. Used for waterproofing. Easy to use. Can paint over it when cured. Best to wear gloves when using it.

Seals and glues
UseI got this to glue aluminium tread plate onto flat steel plate to avoid having to buy more expensive tread like stainless steel which I can't weld.ValueThis was on offer cheaper than certain DIY store with yellow and blue logos. I think it was £7/8 instead of £12 and it's a biggish tube compared to some smaller silicone sizes.ConsistencyIt's somewhat sticky and I used a narrow bead which was quite hard to pump out. When I aligned the two pieces I had a bit of resistance trying to press them together and used clamps in the end.Hold/stickOnce together and dry the pieces are held together very well.It's nice to have a seal as well as a glue.ColourI got Graphite colour which is quite nice and dark grey.SmellNo noticeable smell.OverallI would recommend and will use again if I have the need for both a sealant and glue-like substance.

Good all-rounder!
We use this for just about everything! Sticks like all hell when it's dry, and great for sealing small leaks. Great for indoor and outdoor use!

Better than silicone
Found this about 10 years ago. Sealed round the bath which has an overhead shower and is used about 6 times a day (two footballing sons!) it just started crumbling last week so I had to skim the surface and re-cover to tidy up. I reckon if I’d used ordinary bathroom silicone I’d have had to re-do two or three times by now. Long lasting, cleaner to work with than silicone and also works well as an adhesive (I’ve used it for repairing tiles, sticking on skirting boards and all sorts.) just good stuff.

Sticky and took dark for oak
As an adhesive this is great and sticks amazingly well, as a sealant it's very hard to work with as very sticky. FYI colour doesn't go well with a IKEA oak coloured worktop. Value for money I would say good
