It's Too Hot! It's Too Cold! WE HATE IT !!!

- Silicone rubber and urethane resin like it to be nice and comfy. They don't like it too hot or too cold. Keep them comfortable and you'll make better castings every time.

I'm so glad you addressed this. Temperature and humidity problems can screw up so many things, not just molding and casting, but also painting /sculpting /3D printing. Hate having to bring stinky and/or messy projects into living quarters, but sometimes there's no other choice. My wife is a saint.
Another factor of extreme heat is that it can make you rush and make mistakes. If you were only planning on being in the shop (or garage in my case) for a few mins, you will be very tempted to rush and cause all kinds of problems for your future self.
When dealing with flex foams, it's not just temperature, but humidity as well. Since urethane foams by moisture, when it's dry it can come out hard and crunchy. When it's cold and humid, the foam collapses after you pull it out, and you have to warm it up to get it to puff back up.
Hello Robert I’m just an English nerd but your rubber tips are guiding me …. I keep cocking it up time after time you make it look so easy wish I had half your knowledge ❤️
Oh, great point at 2:30 about condensation. It never even occurred to me to try that, but now I know not to!
Exactly why I'm looking at adding a split A/C system in my garage. It's brutal here in Florida this year! Meanwhile, I continue to take over the home office to my wife's chagrin 😂
That red resin you poured looked like tomato soup lol. Now I want some. Thanks for the informative video as always.
Good tip. Temperature would effect photographic developing times too. Heat = faster reactions. Cold retarded reactions.
How did the questionable mold turn out, afterwards?
Your videos are so insightful. Can you make a video about safety and PPE when handling resin?
Bob, it’s time to be nice to yourself and to your molds and resins. Build yourself a 10’x 12’ room and get an air conditioner!!!! One small unit will do the trick. The problem is, your workspace will be so hot, you won’t want to leave the AC room. I can’t solve all your problems buddy.
Best regards, Richard
Im going through the trial and errors of proper mold techniques i learned from your vids. It really highlights how much of a pro you are 😂
Love your videos! Thank you so much for taking the time to share your experience with us... I have a question... Can you make a silicone mold with an even thin wall like the one used to make desserts... Is this possible at home, perhaps with the help of a 3D printer?
it was 100f last week here, felt like 113f; i also hate it, so myself and resin can really agree on that at least. i have some resin to try some casting this fall, and ill keep in mind to pour it on medium-temp days.
I've never ran into that one personally, I try and keep my place as cool as possible (I'm a Norwegian from Minnesota who lives in the south), which down here ends up between 55 and 75 f, my ac will only get me so cool, and in the winter the neighbors heat's always rising up so even the coldest nights are still like 70. My problem is the humidity, since I saw your video on atmospheric moisture (and I still don't have a pressure pot), I can't open any of my resin between late May and, well I'm hoping it'll start to "dry out" maybe mid-October? I completely ruined 2 gallons of resin last summer and the summer before
Hi Rob! I mess up all the time. At least you made a good video. :)
That is appropriate! Today was 97 here
I live in a city where the ambient farenheit temperature is 65°-72° - 300 days a year.
I had a faulty silicone cast int the past days. The hardener lost its property but I could not notice it. After casting the mold, I waited for a day, and it was still sticky. I waited one more and then two more days. But nothing happened. Then I realized that the hardener is gone. Probably, it was beyond its expiration date. Then, I ended up with messy parts. I would be great if you can show us some ways the clean such a mess. I made a sand box and burried the parts in to the sand and let them dry. After that I washed them off and it seems to be fine now. Please let us know how you clean such failure situations. Best regards.
Can you do a video on epoxy resin casting?

Thanks for your usual advice! I am clear about the temperature issue, but I am even more curious about the humidity of the environment. Do you think there is some magic number in the percentage of humidity in the environment that we should look for? Thanks!!!!
I think if you opened a bottle of fresh resin and made a casting in Phoenix at 105° and then did the same thing in Miami at 105° you would not notice any difference in the casting. The big difference would be how much moisture the resin in the bottle would absorb over time. Obviously, you will have more moisture problems in a humid environment.
have you tried pewter low temp metal fast dip molding and casting? essentially for electroplating after with high temp metal like copper on the low temp metal, about 170C. also why not just have a "cast box" ie ac box for all the temp controlled stuff, with through gloves etc, ie clean room or chemical box, fume hood box, yep small box, not the whole room, in the sauna of yours.
And what about the humidity? Here in Amsterdam it is more or less 22 celsius and with 60/65 humidity... is that okay you think?
can we make mold with tpu filament 3d print?
Good day Sir. I sent you an email with a Project about Resin Casting a 3D Printed Tenjin The Cursed Schoolar from Black ForgedGames. Frankly I think it's uncastable due to it's complexity, it's about 16 parts High Resolution 3D Printed, I want to make the mold/s to cast it in Resin and Electroform it(Copper plating, Silver and Gold plate it)
Resin grandad i have a question! What you know about thermoreactive tactifying resins? Or is this a "go ask a chemist" jobby?
I know very little about them. Tactifying resins are used to add stickiness to adhesives and sealants. I have never come across their use in casting resins.
Yes! A climate controlled shop space should be considered a tool.
Hello , Mr Robert i leave you a message on your email maybe you do not find it
