    concrete pond waterproofing

    I am in the final stage of finishing my concrete koi pond and just have a few questions re waterproofing. I will be using a epoxy resin finish as my last quote. My questions are how long should I wait until filling up the pond and adding fish? Is there any danger to using a epoxy resin finish to the fish over time and is there any precautions I should take/

    Don't know sorry. Not many people finish their ponds like this in the UK these days.

    I've only used polyester resin before, so am not sure about epoxy resins. Although I'd say the longer the resin is allowed to cure the better, making sure that everything is bone dry when applying the resin and ensuring the correct amount of catalyst is used for the temperatures, to ensure it can all cure correctly.

    It's probably best you ask the retailer or even the manufacturer how long it takes to fully cure before you can add water to your pond.

    Once it is cured I would recommend washing it all down first. Pump that water to waste and then start filling up.

    Good luck

    is the epoxy fish safe?
    as Alburglar has said it used to be a thing 20-30 years ago here, where you would use polyester fibres in the render coat, and then paint it with a waterproofing 'paint' like G4.
    but it is prone to failure, and time consuming to empty a pond of fish and water for a week or so to do.

    just about everyone either uses a pond liner or fibreglass....
    though heat welding HDPE sheets on the continent is popular...

    I have used acrylic two part pond seal still good (about 8yrs now). I used it
    around the skimmer as I moved the location also on concrete lintel that the bakki sits on.
    its pretty tough stuff much better than G4 which I have used in the past that eventually pealed and flaked.
