Really good stuff, does what it's supposed to.
Super quick delivery, well packaged, and fair price. Second purchase, used 3 years ago to seal a natural stone (cemented in) on a stream to my pond. Recommended to re-do every 3 years and it is flaking in a few places. Three consecutive coats as per instructions will do the trick. Thank you.

Seals but isn't clear.
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.

Leaky fountain
Came on time well packaged no leaks. Used to seal airline crack in a fountain 3 coats looks shiny but can't tell underwater. Easy to apply .time will tell how good it is.

Not clear.
This is not clear. It leaves a golden honey colour on whatever you paint it on. Wish they were clearer on this as it's affected the look of my water feature. Not sure if it works yet. Still need to fill it with water.

Excellent product
We have used this product for many years. It is an excellent productand keeps water from penetrating through stonework. Does what it says on the tin. Would highly recommend

Does what it says on the tin!
Easy to apply, as directed (although I did dispose of the [cheap] paintbrush afterwards, rather than trying to clean it). Covers and adheres well, and four coats easily managed in 6-8 hours. Didn't find the smell a problem. Inherited an old, defunct waterfall, and fitted new pump and pipework, and re-cemented loose stones, but still some leakage. After application of G4, and requisite curing time, I am pleased to say that the watercourse is now working well, with no water loss apart from expected evaporation. Dries on the stone with a shiny, 'wetlook'. During application, a little of the product dribbled into the reservoir, but laid as a film on the water surface. Easily removed, rather like a piece of used clingfilm!
