How to Clean Epoxy Resin Molds after Use



To clean epoxy resin molds, you can follow these tips depending on the type of mold and the condition of the resin:


Epoxy resin molds are an indispensable tool for any artist or crafter working with resin. However, resin can stick to the mold and leave deposits that are difficult to remove. Below, you'll find a step-by-step guide to cleaning your resin molds and keeping them in good condition for future uses.


1. Remove excess resin: Use a sharp knife or plastic spatula to carefully remove hardened resin from the mold walls. Be sure not to scratch the mold when doing this.


2. Wash the Mold: Fill the mold with warm water and liquid soap. Let the mold soak for a few minutes so that the soap can penetrate the remaining resin. Then use a soft bristle brush or sponge to carefully remove the resin from the mold.


3.Dry the Mold: Carefully dry the mold with a clean towel. Be sure to remove all water from the mold walls to prevent mold or mildew growth.


4. Disinfect the Mold: Mix a solution of water and isopropyl alcohol in a container. Use a sponge or soft bristle brush to apply the solution to the mold. Be sure to cover all areas of the mold to ensure that all germs and bacteria are removed.


5. Store the mold in a dry place away from direct sunlight: Avoid storing it near heat sources, such as a stove or fireplace, as this may cause the resin to melt and stick to the mold.


6. Repeat the process: Whenever you use the mold, repeat this cleaning process: This will help keep the mold in good condition and prolong its life.


7. Protect the Mold: Consider applying a coat of resin sealant to the mold prior to use. This will create a protective barrier that will make the resin easier to remove and help keep the mold in good condition.


8. Prevent Mold Thinning: If you notice that the mold is thinning out or getting hard to remove resin, you can use fine sandpaper to smooth the walls of the mold. Be sure to clean the mold thoroughly before using it again.


If the mold is made of silicone: You can clean it with a dry and soft cloth or with a little alcohol suitable for this use. Do not use abrasive or chemical products that may damage the silicone.

.

If the mold is made of plastic, metal or wood: You should use a release agent before pouring the resin, to prevent it from sticking to the mold. Apply the release agent evenly and without excess, following the manufacturer's instructions.
