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!

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.

Really good but there is another option
This product is pretty good, I really liek that it is not solvent based. I do find it hard to work with because it is acrylic it sticks to absolutely everything in sight you need to be careful.there is a product on the market almost the same as this for £4 a tube.

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.

Great product!
The media could not be loaded. Perfect for sealing my pond, great all round

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
