Howdy folks! Yesterday I shared my bottle cap resin creations. The clear polyester resin took 3 days to cure at 69 degrees and 66% humidity. I used 15 drops of hardener to 1 oz of resin as the package directed for items 1/8″ thick. Today I am showing you my first cast resin pieces. I used the same ratio or 1oz resin and 15 drops hardener (catalyst) and I added a pea size dollop of green acrylic paint and some pearl ex to the mix. I think I was supposed to add the color and pearl to the resin before hardener but I forgot and added it after. No big deal, but the pearl-ex probably would have mixed in better, I had some lumps as you will see in the silicone mold. The cast resin took 5 days to cure, it was hard 24 hours after pouring but it was sticky for days. I tried a few different molds. The one that I liked the best was Casting Craft, it was smooth and the resin cured quickest in here:
I had a duplicate mold of this one by Makin’s Clay so I decided to risk using it. It seems sometimes resin could be permanent in some plastics. This worked great and it took maybe 12 hours longer to cure than in the Casting Craft mold. I am excited because I have lots of this brand!
I LOVE the detail from the Martha Stewart silicone molds but they stayed sticky the longest. I know if the polyester resin is exposed to air (not touching the side of a mold for instance) it takes longer to cure or may remain sticky and maybe the matte finish of the mold affected the cure time. It has a slight tack to it at day 5 but it is getting much better each day.
Please note! Before I poured the resin in the molds I washed the molds, dried them, sprayed them with Casting Craft mold release/conditioner and let that dry overnight. Already this procedure is more work than anything I would ever cook, geez Louise, but I was determined to use up this expensive supply that has a shelf life 🙂 After all the pre-show prep I mixed the resin, poured it and left it alone. That is the hard part. Really. I kept visiting my resin (don’t do that) and touching it to see if it was sticky (hence the fingerprints on the back) and sometimes I’d take it outside and put it in the sun because I read somewhere it could speed up the process but I don’t think it did a lick of good. I feel like the weirdo who plays classical music for his plants. Really, you should pour the resin and leave town for a few days, that’s your best bet! 🙂 I’ll let you know if I discover anything else about this fascinating medium. I reckon the epoxy resin is a much more user friendly and forgiving resin but I will not be trying that until I use up this bulk can of ever-loving polyester stuff. That’s it for me today, thanks for stopping by and til next time happy crafting!
Hello folks! For those of you following along in my resin adventure I am happy to report that after 3 days my resin is hard and glassy, it was bit dicey for a while and it didn’t help that I kept visiting my creations and poking them to see if they were cured yet. Note to self: KEEP YOUR GRIMY PAWS OFF THE RESIN! So for those of you at home who want specifics it took 3 days to cure my polyester resin (mixed per package directions) with a room temperature around 70 and humidity at 66%. Higher temperature and lower humidity would have taken less time I suspect. Hey, here is a fun fact, thicker pieces take less time to cure, it seems that resin makes it’s own heat that speeds it’s curing process, Good to know. Also, don’t stick your fingernails in the resin to see if it cured…just sayin. BTW it is What’s on your workdesk Wednesday! On my desk are some bottle-cap resin rings and barrettes I just glued, paint from a project I just finished and other assorted supplies…
But wait, there’s more! I can’t even sit down in here, it is madness I tell you!
Crafty fun madness that is:) Want to join the crafty fun? Head on over to Julia’s blog the Stamping Ground and see for yourself! Thanks for stopping by and til next time happy crafting!
It’s true, there is a craft supply that scares me: Resin. I have read resign blogs, watched videos and read the instruction on the large bottle of resin I bought (BTW I bought the Polyester stuff which is more of a challenge than the typical 1:1 ratio epoxy stuff) and the more I read the more confused I got! There are so many variables for error with resin: The room temperature has to be above 70 degrees, my studio is unheated and I live in Maine (I’m sure I’ve whined about that before) so the only months my studio is warm enough is July – September if I am lucky. But the humidity needs to be low, well when it is warm enough the humidity is high. Also the amount of drops if hardener in the resin I bought varies with environmental conditions and thickness of cast piece. I could go out and buy the other kind of resin but it is too late to return what I have and I morally need to use it before I buy more. I only bought the big jug of resin because I had a coupon and no plan…damn those 50% off coupons LOL!
So made a plan. Step 1, Clean molds. Step 2 Spray with mold release and let dry. Step 3 collect papers I want to encase (they need 3 coats of mod-podge, even the paper edges need to be sealed, man this is getting to be more like cooking with each step, ugh, PS I totally skipped the mod-podge, I’m a rebel ha ha!) Step 4. Gather inclusions. Step 5. Cover work surface with a silicone mat and make sure I have a plastic frame use as a dust dome nearby,
So resin fumes are toxic as I understand (when did that ever stop me?) and I want to do this at the end of the day and preferably when my kids are not around but since I only have a warm enough studio in the summer I have to do it now. I am hoping the fumes do not travel from my cellar studio to the rest of the house. That would stink…no pun intended…OK pun intended! 😀
Also resin has a shelf life, It was expensive and I don’t want to waste it but I don’t want it to go bad while I think about what I want to do either. I love the look of resin jewelry, I hope I can make some good pieces.BTW before you judge me on the excessive amount of beer bottle caps I asked my niece to save me hers and she got friends to do the same, no intervention needed LOL! I’ll let you know how these pieces come out after they cure, wish me luck! So, are there any crafts you are afraid of? Til next time happy crafting!
