Bonda G4 Pond Sealer Clear 500g

I bought this to seal a terracotta pot so I could DIY a water feature and it was great. It leaves a shiny almost patent like effect on the pot but that was fine as I only applied it to the area that would be holding the water. It does smell very strong, even using it outside you could smell it indoors. But apart from that it was great.

This is a “paint on “ product which creates a thin sealing layer over whatever you want to waterproof. I’ve used it to coat 3 small rocky r pools in my back garden. Easy to apply but thorough prep is vital. I’ ve applied 3 thin coats for max effect. I’m well pleased with the product.

Very effective sealer but it doesn't go a long way. I used it to seal a concrete bird-bath which kept losing water (and flaking) through absorption. I covered the whole stand, not just the bowl to stop winter damage and used almost 500ml with the recommended four coats. The first coat soaks in and the rest build up to leave a high gloss finish. Great seal which should avoid further winter damage but the birds had trouble getting a grip on the smooth surface. A bit of roughing-up with a file did the trick (on the sealant, not the birds) This will do for any non-toxic sealing job and looks like it will last a long time. Recommended. Note, (Oct 2013), after six months in all weathers: The finish is unblemished and has weathered to a slightly darker shade. No flaking or blistering and the bird bath looks ready to face winter. So, very pleased with purchase.

Great stuff. Water slides off. Used on slate for a ware feature. On stones and slate makes things look varnished and “Wet”. Use crap brushes, you wont get this stuff off. Also, I never use gloves because I’m old school. This is so hard to remove from skin - be warned - use gloves. Very good products. It does smell but not crazy. I felt it actually went quite a long way.

Does what it said on the tin

I think the sealant is good as far as a sealant is concerned. However, it does dry a slight golden colour which changed the look of the bird bath I had painted.

Great product best in the market if you own a pond’s

Used this to seal the inside of a traditional stone trough which we are using for a water feature. Seems to have done the trick with no visible seepage but it is a pretty expensive product.
