    Default Epoxy paint Hardnener

    I am probably not the only one who has can or two of paint waiting for the next project. What I found is the paint holds up fairly well, but the little can of hardener goes bad real quick. Any tips to make it last longer? I keep the paint and hardener in a styrofoam container already, but it doesn't do much good for the hardener. Any thoughts? Stan

    buy your hardener in smaller sizes. I tried to split it up into smaller jars. I did not last. i had one unopened can that did not last. That makes me thin it has a short shelf life. I have only tried this with akzo products

    I only use epoxy primer paint, which hasn't been a storage problem. For top coat paint I use single stage acrylic enamel and use "Transtar" wet look hardener. They redesigned their container a while back and use a proprietary cap that seals well, and doesn't glue itself to the container. I've had this can of hardener for well over a year and it is still "wet". I get all my paint supplies from Finishmasters. . . . I am not a paid spokesperson for Finishmasters

    I notice you're from California, Stan. I know your state has very strict laws regarding paint so perhaps the products I can use in Florida are not available in Ca.

    Maybe this might apply. A friend of mine, FL state water guy, told me to turn my pvc glue cans upside down to make them last longer. Standing them on their lids seems to keep the liquid inside sealing the only inlet, the lid or cap. I have had great results keeping the glue longer, maybe this might work for hardener, if not maybe everyone reading will have longer lasting glue now! Good luck.

    Oxygen is the culprit. If you can replace the air right before you put the cap on, it will last longer.
