### ⭐⭐⭐⭐⭐ Works as sealant on different surfaces
*by N***A on 13 September 2025*

### ⭐⭐⭐⭐ Very effective sealant
*by J***Y on 27 July 2024*

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.
