In cases where you want to make layered casting, you should wait for the underlying layer to cure for a while. After the first drying and touch drying time, the second layer can be applied. This time varies according to the epoxy type and ambient temperature. The best method of determining the time is to touch the product surface. If you don’t feel sticking when you touch the surface with your fingertip, you can pour the second layer.
Please Note: Take care to protect the epoxy surface from dust, etc. external factors in layered castings.
