4.25” Round DEEP Coaster Mold - 4 PK

Regular price $22.00

Similar to our original deep coaster molds, these are just a bit bigger for even more options. 

Have fun creating molds or art objects with inclusions like flowers, whales, scuba divers and even mountains!

They come in a 4 pack, because one mold just isn’t enough!

Measuring approximately 4.25” in diameter and .8” deep, these molds are

  • Flexible, soft and reusable
  • Made of BPA free silicone
  • Heat resistant: -40 to +446 degrees Fahrenheit, (-40 to +230 degrees Celsius)
  • Non-stick for easy release

The finished coaster size is just under 4” in diameter and .75” deep  

Tips (always follow instructions for the resin you are using - these are meant as general guidelines):

  • Always pour your resin into the hardener (pour hardener into the mixing container first, then resin). 
  • Stir resin with a plastic or silicone stirring stick to reduce air bubbles. Wood is not recommended as it can create air bubbles.
  • Let resin sit a few minutes after stirring to reduce air bubbles.
  • Don’t use a torch or heat gun as it could damage the molds and make it difficult to de-mould, causing them to tear - this is especially true near the edges.
  • Wash mold as needed in warm soapy water.

    Perfect size

    I got these to make it easier to do a flood coat on some coasters to give them a smooth finish.

    4.25” Round Silicone DEEP Coaster Mold - 4 PACK?

    They look good. Have not used them yet.
    No fault on your part. The postal service sent them to Melbourne, Australia before the package was redirected to the UK.
    Thanks I'm looking forward to casting Resin soon.
