How to Avoid the 3 Most Frequent Mistakes Made By Resin NewbiesPosted on 15 Sep 13:49
You first need to know that epoxy resin comes in 2 parts: a resin and a hardener. When these two parts are mixed according to directions, a chemical reaction occurs which causes the liquid mixture to cure. When this chemical reaction is somehow prevented or disrupted, a perfect cure is no longer possible, and the result is a sticky mess! Below is what not to do! :)
1. Not Measuring Accurately
parts to ensure the ratio is indeed equal, because any material that cannot
catalyze properly will remain uncured and sticky.
2. Not Mixing Thoroughly
both parts together thoroughly. Again, if any material cannot catalyze properly by
any means, including not being blended well enough, it will not be able to cure
fully. Mixing vigorously for three to four solid minutes, scraping the sides and
bottom of the container, should ensure everything can thoroughly catalyze.
3. Trying to Cheat the Cure Time By Adding More Hardener
Sometimes people think they can speed up this cure time by adding more
hardener to the mixture, however this only throws off the delicate 1:1 mixing
ratio and causing curing issues. The best way to encourage curing is to
increase the room temperature, since curing is accelerated by heat.
If however you have made these mistakes already and need to know what to do to fix them, see our video on applying a second coat of ArtResin.
