Bonda G4 Pond Sealer Clear 1kg

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.

Good sealer

I used it to seal a pond waterfall of glued (with silicone) together rocks. Has a sort of yellow/brownish/clear tint... but it looks natural on stones and cannot be seen under water Quite sticky and thick (a bit like Mable syrup), and connects well to stone or similar materials. Not so for silicone or plastics.... though it still does create a protective film, even if it does not "glue" so well to e.g. silicone. Not flexible when cured. It will likely crack if painted on moving stuff. Finger dry rather quickly (for second coating something like 3 hours of curing is enough, or even less - in good weather perhaps 1-2 hours) Cures well under even cold and humid weather They recommend 2-4 coats, imo 2-3 is quite enough and I can imagine even one coat to be efficient in some cases. It all depends. PROS: Does what it says on the box and is easy to work with. Durable and can take a beating once cured. CONS: Not flexible when cured, and does not seem to bond very well with plastic or silicone surfaces.

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

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.

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.

Perfect

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!
