This was quite the adventure - a tale of stress, late nights, success, and failures. Guess that’s what happens when it’s holiday season and a rush order comes in! We had to make 80 concrete coasters for West Elm and we learned a lot about making master models and silicone molds along the way. Hopefully this video is not just a concrete how to but also a mold making how to.

The Precision Board Plus was an AWESOME material to work with. It’s a high density urethane foam but it feels like stone and has a smooth sandable, non-porous surface. It carved like a breeze on our X-Carve. However, we didn’t know until it was too late that the silicone type we got, Mold Star 15, was incompatible with urethane. Automotive primer to the rescue! We use this stuff to smooth out 3D prints all the time but it also made a great barrier between the urethane and the silicone!

Once we got to actually mixing the concrete, that was the easy part! Here are some tips you can use for any DIY concrete project: start with less water than you think - a little goes a long way! Agitate your molds to remove concrete bubbles - you can shimmy and shake em or put a sander next to them to vibrate them. They can be removed before fully cured, but they need to cure before you paint them!

Hope you can apply some of the tips in the video if you’re working on silicone molds, diy concrete projects, or have any concrete how to projects ahead of you!
