Epoxy Resin Drying Surprise and Embarrassment: Lessons Learned

What This Video Shows

In this video I share my embarrassing experience with epoxy putty that caught me completely off guard. I had used two-part liquid epoxy glue before, where you mix two liquids and they harden over time. But epoxy putty is a completely different product with very different handling requirements, and the instructions on the package did not prepare me adequately. I needed to fix a leaking ABS pipe, and people at Home Depot recommended epoxy putty for the job. The instructions said to use within 2 to 3 minutes after mixing and that it sets hard in 15 to 20 minutes. But what exactly does mixing mean for putty? There is no liquid to pour and mix. The mixing for epoxy putty actually means kneading the putty between your fingers until the mixture becomes one uniform color throughout. And here is where the surprise hit me: as soon as I started kneading, the putty began generating significant heat through the exothermic chemical reaction. It got hot in my hands very quickly, much faster than I expected. And then within what felt like seconds, it hardened into a rock-solid lump before I could even apply it to the pipe. The entire putty was wasted because I did not understand that the working time starts the moment you begin kneading and that it is genuinely only two to three minutes before it becomes unworkable. I was frustrated and embarrassed, but I turned it into a learning experience. The lesson is clear: with epoxy putty, you must have everything prepared and ready before you start kneading, and you must work extremely fast once the kneading begins.
