Why is my resin still sticky after pouring?

If the resin has not cured properly or has sticky spots, it could be caused by a few things:

• the resin was not accurately measured at a 2:1 resin to hardener ratio, by volume.
• the resin was under mixed.
• the sides and bottom of the mixing container were not scraped, resulting in unmixed resin and hardener stuck to the sides of the container. Additionally, if the resin was scraped out as it was poured from the mixing container, the unmixed product stuck to the sides will contaminate the mixture, resulting in soft, sticky spots on an otherwise cured surface.
• If the temperature is too cold during the curing process (less than 50F or 10C) the resin will not cure properly.  Try moving your piece to a warmer environment to see if it hardens up.
• too much colorant was added, throwing off the ratio between the resin and hardener required for the two parts to cure properly.

If you find that the resin is still sticky after 24 hours in a warm environment, it will not cure any further until additional measures are taken. Scrape off any liquid, runny, resin as best you can (sticky is ok).  Sand down areas that cured properly and carefully remove the sanding debris.  Pour a fresh coat of accurately measured and well mixed Industrial Clear and allow it to cure in a warm, dry environment, ideally between 70 and 80F (21-27C).
