BondaG4 Pond Sealer Clear 5kg

Easy to use and does an excellent job. Opening it was v difficult for several people. I resorted to using an oil filter remover to access the contents!

I have renovated an old pond. The rendered surface was brushing away easily and the G4 has soaked in, stabilised and appears to have waterproofed this well. Other parts had still got remnants of previous acrylic pond paint, which I painted over, though the instructions suggest the surface needs to be bare, dry render/concrete. Consequently coverage was twice what was predicted. Looks good. Need to see how it holds up in 3-10 years!

Excellent product did what it said on the tin.I was having trouble with my garden waterfall always leaking water and having to top up regularly.After using the G4 Pond sealer clear and following instruction I have a great garden waterfall working and not leaking water through the stone work..

Just applied the first coat. It looks okay. However it could have done with sturdier packaging. It had one layer of bubble wrap and a thin cardboard box. The tin was very heavily dented but thankfully not punctured.

Easy to apply and quick drying. Seems to do the job so far but won't know fully until we get some serious rain to fill the pond.

Wasn't sure if I had ordered enough. 1st coat nearly used half amount ordered, white render soaked it up! Then next two coats were luckily quarter the amount, I phoned around locally and struggled to find a stockist so make sure you have enough due to the having to paint all 3 coats in one day. I image if you try and paint another coat after previous has gone off it would just run off! Covered looks sound but does have yellow tint.

Best sealant I've used.

Used it on the pond but made no difference to the 'leak' had to have it done with cenent eventually but used this on top and so far so good but only time will tell - good supplier
