Mixed feelings about this product. I used it to seal a fibreglass pot after it was recommended to me to use on fibreglass and it has bubbled up and disintegrated twice within six months. However I used it to seal terracotta pots and that seems to be holding up quite well.

Didn’t do as I expected, I followed the instructions promptly, allowed drying time as noted. Filled the pond (about 2wks ago) drained it to clean it out and was surprised to find that the sealant had bubbled everywhere and was flaking off causing a mess!

I have bought this product twice to reseal an existing pond, I have followed the instructions both time, 2 X costs and a week to cure and both times this product has broke down and bubbled. Not sure what I'm doing wrong but off to try something else.
I should have researched a bit more first. After 5 coats, no rain, allowing a week of warm weather I still have bubbles appearing. The product is not waterproof and I’m no better off from when I started. Not a cheap product and a complete waste of time and money. I’m surprised Bunnings still sell the product after reading all the reviews. Now having to work out how to remove the product and find one that actually works.
Easy to use and did the job. I didn't need to use a whole lot as a little bit goes a long way. I sealed a huge terracotta pot to make a pond. The pot was quite porous, so I needed a good, plant-and-fish-safe product to seal it permanently. So far so good with this product.
Read all the reviews before you even consider this product ... and heed them. I didn't, to my great regret. I used this product on an above-ground, under cover, cement block/cement render pond. Concrete had cured and dried for months. Four coats applied and left to cure for weeks. When I filled the pond with water, blisters appeared. Everywhere. It appears to be coming off, but not uniformly so removing it is not going to be easy. I suppose there are tricks of the trade that, if followed, make this an OK product, but its not for the handyman. Now I can't find how to clean it off.
I’m a waterproofer by trade I used this product supplied to me by a friend it worked great like anything follow the manufactures specs and it will work. Don’t be a Neil the pond guy who went to great expense not draining out his pond and letting it dry properly before applying paint.Neil your a belter
Unfortunately a lite shower fell during the curing process, leaving the product useless !But I’m not even sure had it not showered it would have done the job?Now I’m looking for a better sealer .
The direction/details of this product stated that the curing time would be 7 days.6.5 days after applying this product, we had a light rain-shower, subsequently, the paint blistered and bubbled leaving an unsightly finish on the pond's surface. In addition, I applied 1 - layer of the water-proofing mesh which was supposed to compliment (harden) the process; unfortunately, that too was a complete waste of time & $$.If you have all the time in the world and reside in an area that never rains, this products for you.
