This flat 90mm Square Cornered Coaster Mould has a smooth interior and produces a beautiful coaster with a professional finish. Use our heat-resist resin to make something that is not only functional, but great to give to friends and family as gifts or sell at craft fairs.
- Dimensions: 90mm width x 90mm length x 9mm depth approx.
- Square corners
- This mould takes approximately 75ml of resin or 130g of JESMONITE® to fill.
If you're using these moulds to make coasters, we recommend that you fill your edges and then add a 3mm thick clear layer of HEAT-RESIST™ resin first in your mould. Let it set and then add more resin with colour, ink, glitter, flowers etc. Once turned out, what was the bottom will be the top and heat-resistant up to 90oC! Remember that our HEAT-RESIST™ resin needs 21 days to achieve full cure, so don't place a hot cup on it too early.
If using to make a JESMONITE® coaster, remember to seal the coaster before use with PROTECT-IT™ sealant to make it less porous.
We think you might be searching for mold (if you're American) or moldes (if you're Spanish) and even silcone or mild (if you've misspelt it) so we hope you will find what you're looking for now!
How to look after your new mould: top tips from the Resin8® team
When you first receive your new mould, we always recommend giving it a little wash with warm soapy water and leaving it to full dry before its first use to make sure it is super clean before pouring your make.
Our silicone moulds can be used multiple times - to get the very best resin results it is important to care for them perfectly. Keep your mould in the bag it comes to you in and store carefully. Strong UV light can damage your silicone moulds so make sure to keep them away from direct sunlight. Moulds do not like to be stacked or kept contained in a box with other items, this will result in the mould losing its shape. You may want to leave a casting in your mould when storing it away for longer periods of time, as this will help retain the shape of the mould. Moulds that are more complex to demould from will not last as long as straightforward, plain moulds.
It is best to use a heat tool such as an embossing craft gun to rid bubbles from your creations, naked flames can damage the outer edges of your mould. Take extra care when de-moulding your creation, pay special attention to not scratch the interior of your mould with long fingernails.
Any residue left in your mould once you have finished using it can be brushed out with a soft bristled brush such as a watercolour paint brush. Do not use sticky tape to de-tack dust, fluff, or glitters - doing this will remove the interior shine within your mould.
If your casting comes out dull it could be that the mould has come to the end of its life (or that the mould doesn't have a shiny interior surface). You can keep using moulds that are past their best - it just takes a little more effort. Add a thin layer of resin to the casting or use polish and a cloth to bring up the shine.
