In cases where you want to make layered casting, you need to wait for the underlying layer to cure for a while. After the first drying time, which is referred to as touch drying, the application of the second layer can be started. This time varies according to the epoxy type and ambient temperature. The best method to determine the duration is to touch the product surface. If you do not feel sticky when you touch the surface with your fingertip, you can pour the second layer.
Attention please: Dust etc. on the epoxy surface in layered castings. Take care to protect it from external factors.
