Circular coaster mold 431 is our most popular mold!  It is 4" in diameter and 3/8" deep.  This mold holds 2 1/2 ounces of resin when filled.  Some buffing and/or sanding may be needed on the finished piece to achieve a smooth surface.

How to Use Resin Molds: Remove any dust and particles from your reusable mold. Molds do not require mold release when casting with resin, however, it is strongly suggested. We recommend the use of Castin' Craft Mold Release and Conditioner.  Protect your work area with freezer or wax paper. Treat mold with mold release and allow to dry. Place mold on a level surface and fill the cavities to just below the top. Once the pieces are cured, turn the tray over and press the center area of each piece while flexing to release the casting.  Do not use sharp objects to demold your resin as you will scratch your mold.  Be sure to also read our plastic resin mold care tips to ensure a long life for your molds.

See how to use this mold to make your own bottle cap resin coasters or resin coasters with leaves.

I wanted to love it

... I still do. I noticed there were scratches in the mold when I received it, but they seemed minor. I went ahead with my projects. The piece came out ok with a little effort. The scratches are a bit noticeable and every coaster I’ve made is uneven. I’m not that satisfied. But I will keep trying.

Hi Yolanda, I'm sorry your coasters did not turn out as shiny as expected. You can use a small amount of a doming resin on the surface as a glaze or apply a couple of light coats of our resin gloss sealer spray to get the finish you want. You are welcome to contact us for more details on how to get this accomplished.

use the backside...

I like this mold, my coffee is sitting on it right now. I used it differently though, try flipping the mold over and over and use the backside it makes the same coaster only with a raised lip

Circular Molds

The circular molds are easy to use. They do tend to scratch easily so be careful. Putting them in the freezer for 10 minutes helps to get the dried resin mold out.

Works well

Bought two to make beer cap coasters. I used cooking spray as mold release. Very happy with the result .

Circular Mold 431

Really love this mold. I like that it isnt real deep and you can see your air bubbles easily. If resin does not come out easily, I pop it into the freezer for a few seconds, and pop it right out!
