Bonda G4 Pond Sealer Clear 1kg

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!

I gave it two coats and it cured the leak that was impossible to see.

The pondsealer did exactly “what it says on the tin” . It sealed the cement very well. I had made a watercourse/waterfall and it all sealed well and I’m pleased with the result. The only downsides are that it is not good for the environment and the brushes used need special cleaning (I actually used old brushes and then threw them away when finished)

We used this to seal our hand made waterfall on our pond, works brilliantly.

This product is great, we have had a pool for 30 years, and suddenly started leaking, not sure where the leak was, we used this product and hey presto, it leaks no more! It has sealed the floor and walls of the pool.

Great stuff I used it to seal a York stone ryll on our pond it drugs faily clear so when pump is running you cannot tell its been painted on . If you get this product go in to one of many cheap shops and buy some very cheap brushes because trying to clean them is a night mare . I tried rappinit in a plastic bag but when I came back 2 hours later it had set solid . Next I tried laying the brush on some duct tape and folding it bacck on it self this worked but if left over night rock solid , just get cheap brushes and bin them after each coat .

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.

Great product I have used it a few times over the years. setting up a new waterfall feature.Every few years just srip out the pond jet wash and reseal once its completely dry and no chance of rain leave for a few days .
