## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Does the job - dries very slowly.
  

*by J***. on Reviewed in the United Kingdom on 10 May 2017*

I used this to seal PVC conduit and associated bits as part of a hydroponics setup. I was looking for a non toxic non chemical sealer and this does the trick.Much cheaper than some of the 'food safe' alternatives but this is perfectly safe as far as I can see. My only criticism is that it dries quite slowly. If you fill any depth of it expect at least 24 hrs to dry through. Also, it is mucky to handle staining your fingers black at the slightest touch and tricky to wipe off.. Perhaps some gloves would be a good idea.

    Pricey but does the job
  

*by D***N on Reviewed in the United Kingdom on 23 May 2017*

Very expensive when compared to normal silicone but... It's not normal silicone!This stuff is fish friendly and had done a great job sealing the pipe/cable entry points in my liner, filling a hole in my water feature, sticking down liner folds and I've still got most of the tube left.It's hard to get excited about sealant but it does so the job very well so comes recommend.

Was having issues dealing liner to pond skimmer, this has worked and has not failed after purchasing.
