Silicone mould for Ocean Coasters

  • Embossed coaster mould
  • Contents: 90 grams
  • Dimensions: 9 x 9 cm

Set of 4 moulds to make fun coasters. The coaster mould is made of silicone so the epoxy will not stick to it. This also makes de-moulding very easy. Moreover, the mould can be used several times after use.

Tip: release agent spray can simplify removing the cast from the mould and can extend mould life. Release agent can make the mould matt.

How to make Ocean Coasters

You make an ocean coaster in two parts. To do this, follow the instructions below:

Part 1 (sand/land)

  • Prepare the epoxy you want to use for this mould. We recommend choosng an epoxy with a low viscosity (fluidity). For example, use RESION UV Epoxy Resin or Resin Art Epoxy LV.
  • Colour the epoxy as desired with pigments.
  • Pour the epoxy into the mould and remove air bubbles using a gas burner or Bubble Burst.
  • now let the epoxy cure sufficiently (about 24 hours).

You can also use porcelain plaster for this casting. This gives a nice porcelain look and is easy to colour in with, for example, Posca markers. In addition, the next casting (part 2) will adhere well to the porcelain plaster.

Part 2 (water)

  • Now pour the epoxy in a different colour into the empty part of the cured epoxy.
  • In the photo, we have used TransTint.
  • Let this layer also cure for at least 24 hours.
Tip: use UltraCast epoxy resin as a topcoat to increase the heat resistance of coasters (up to 75°C). This way, you reduce the risk of circles on your coasters.
