## Questions & Answers

**Q: I have a stone effect two tier fountain and the bottom resivoir leaks could i poor in your prodduct in the resivoir and leave to set? its very heavy**
A: Hello Andrew. I have a three tier waterfall with a "plastic" dish at the top. My problem was the concrete pointing between the dish and the stones had cracked and become porous. I renewed the pointing and applied several THIN coats of the G4.You need a completely dry surface and apply the sealant in THIN coats. It says on the tin, that it is for concrete, but I used an old plastic dish to pour the stuff into, to work, and it has left a complete coat all over the old dish. It looks like new!! With that in mind, it seems that it would bond to various different surfaces. I bought the 500g tin, and it went quite a long way. Reading other comments, before I used the G4, it seemed that you really need to throw the brushes away, after using them, as they do not clean successfully. I found several old brushes and didn't bother to try cleaning them. I hope this will help. Good luck.

**Q: Can this be used with an acrylic dye mixed in, or applied between layers?**
A: I don't see why not, however, there's a slight yellow tinge to it when it dries so you should take that into consideration

**Q: What’s the directions for this?**
A: Not an expert, but it was ensure s porous service with no major cracks, so rendered. Then paint on, 3-4 coats all in one session....I was worried I would run out! First coat used loads! However next two coats were a lot less. I made mistake that clear is not in fact clear, so my ponds is a yellow colour. Tempted to drain and cover with black...but night looked into it yet. Pond so far has showed no signs of leakage. However coping stones I only covered with one coat has worn away, somake sure you coat everything atleast 3 times....

**Q: Product info says it will kill fish, is this if it gets into the pond in it's liquid form or what? And how long after final coat can the water go in?**
A: Good Afternoon,

Yes, this is in liquid form, once the liquid cures this is completely safe - this takes 72 hours for the full chemical cure, but the liquid should be dry within 24.

### ⭐⭐⭐⭐ Seals but isn't clear.
*by F***K on 8 August 2025*

Seals the stepping stone slabs but isn't clear... leaves a pale caramel/honey colour. The stepping stones were used in my pond on a side where ive a tiny leak about 3"~4" from the top I can't find... hoping that sealing these small slate before using with the black expanding pond foam would help to stop it. Only way - as I knew it would have to be - is to use a new liner at some point next year.
