How to demould?<br /> After confirming complete curing, you can use the release agent to help quickly demould.<br /> Pay attention to do not use strong corrosive material, which will shorten the life of the coaster, and even lead to the failure to demould and damage the moulds.<br /> <br /> 3. How to clean?<br /> After completing the silicone moulds, you can wash them with warm water and soap or rubbing alcohol, then use a soft cloth to wipe clean. Pay attention to do not use solvents to clean your moulds.<br /> <br /> 4. How to store?<br /> Place the resin moulds in a cool place to avoid direct exposure to dust and sunlight for better protection.<br /> Pay attention to ensure that the mould is completely dry before storing it.
