1. Sanding

One of the simplest and most common chemical methods for frosting acrylic is sanding. This method involves using sandpaper or a sanding block to manually create a frosted effect on the acrylic surface. The abrasion caused by the sanding process roughens the smooth surface, diffusing light and creating the desired frosted appearance.

To achieve a consistent and uniform frosted effect, it is recommended to use fine-grit sandpaper and apply even pressure while sanding. It is important to note that sanding can result in scratches or marks on the acrylic surface, so caution should be exercised.
