Can this product be used to coat a concrete fishpond, i.e. for a fully immersed condition?

Yes Flex Seal Liquid can be used to coat a concrete fish pond. For best results sweep off the concrete to make sure there's no concrete dust and then apply. Let dry for 24-48 hours. Flex Seal Liquid is food grade safe, so your fish can swim around in it with no worries.

To what depth (thickness) can this be poured and still cure?

Flex Seal Liquid can be poured to any thickness desired. We recommend pouring in layers 1/4-1/2" thick to ensure the product cures completely. For a normal application Flex Seal Liquid takes 24-48 hours to completely cure.

Very thick!!

Very thick! Used a whole gallon on the floor of my pickup bed after I rhino lined it. Very difficult to brush and roll on. Ended up pouring it onto the bed and using the brush to just push the rubber around. It will be very durable when cured, just wish it was thinnable so you could use it in a thinner coat. Price is a bit high too.
