Pond Armor SKU-WHITE-GA Non-Toxic Pond Shield Epoxy Paint, 1.5-Gallon, White

Worked. Water tight. Problem is it was white but has yellowed. Was beautiful the day it dried. But now is a pretty ugly light yellow. Nothing will clean it. The color is in the epoxy.

Excellent product. Worked to fix our leaking concrete koi pond. Mixes like an epoxy and is just about as thick and difficult to spread. I applied it with a roller but would caution against using anything but the best top quality roller as the mixture is very hard to spread and a cheap roller that comes apart would be a disaster with this product. Must be applied very quickly as it sets and skins in about 30 minutes. I got about 70% of the coverage expected, but with a little experience or practice 1.5 gallons should cover about 500 square feet for applications similar to mine. This is based on application to a rough concrete surface early in the morning with an ambient temperature of about 90 degrees. Six months on and the pond, fish, and plants are all doing great. Extremely slippery once cured, so use extreme caution moving over the surface when wet or submerged.

We had a fountain with tile on the sides and cement in the bottom. Couldn't find the leak. The white sealer applied easily. Just follow instructions and it worked great. We ordered more based on reviews and the product went on just the way the directions stated. We now have extra product. Very happy with this and this will be the product we use if there is a leak again. It didn't seem too thick or runny when applied. Did all prep work.

Working time is minimal, wasted the produced as I was only able to use a small amount prior to the product becoming solid

I can't comment on the product itself because I haven't been able to use it. I originally placed an order for white coating but received black. The replacement order that came was also black so I placed a new order to avoid possible continued confusion. Unfortunately, for the third time, I received black.
