I used this to repair my garden bird bath, which had cracked in the frosts last winter. Lots of people told me it wouldn't work, but it's still watertight so far! I've knocked off a star because it is so difficult to to get out of the tube, despite borrowing a proper caulking gun. I made a real mess of it and had to use my fingers to try and smooth it out. That said, it's on the underneath so doesn't show much, but I wouldn't be able to do a neat job anywhere that would be seen.

This stuff goes on great & smooths out really well I also like the finish, I can't comment on durability yet but it says its good for 15 years we will see. Overall I really like it I will buy more.

Top quality product easy to apply and great rich white colour when it's cured. Very flexible and neat finish.

Had lots of gaps between white pvc window frames and stonework. Product formed strong bond and sorted all the gaps. Easy to use.

Purchased to seal around pipes that exit through an external wall. I applied the sealant on a cold day and found it fairly difficult to apply. It dried nicely leaving a flexible transparent seal which was exactly what was required. The larger gaps took a couple of applications with adequate time to enable each application to fully cure. No more annoying gaps around the pipes and the transparent sealant does not stand out against the brick.

Not used the product yet but purely based on saving money this is £3-4 cheaper than B&Q/Screwfix so very happy with savings when buying quite a few of these!

It did the job brilliantly, but it leaked out the back of the tube, so much so I threw 1/2 tube and the gun away on 1st use
