    No, it’s not really made for this purpose. Mainly it’s used to seal concrete in basements, foundations. Properties of such products must be detailed as to their safety, proper use & any health risks that may be present such as respiratory, skin irritation, flammability, etc. These properties are detailed in the MSDS (material safety data sheet)
    Here are:
    1. Proper uses product per manufacturer:

    There is something called “Koi Kote Concrete Pond Sealer” It is safe for your fish.
    It has no toxic smells or fumes & a seamless lining so bacteria are unable to grow.
    It comes in clear or colored finishes. It’s best to do 2 or 3 coats of it if possible.
    Here is more info about it & suggestions for care of your pond!
