Introduction: Sanding Polycarbonate for Frosty Effect
I did this at TechShop Menlo Park. http://www.techshop.com
These large sheets of polycarbonate are to be sanded down for a frosted effect to be used in the construction of large art light-boxes.
Step 1: Peeling
The shiny surfaced sheets are revealed by peeling the protective layer from each side.
Step 2: Sanding
Using an air rotary hand held sander and 40 grit sanding discs and protecting the face with a dust mask we indulge in hours of making circles on this piece of plastic.
Step 3: Break
We pause for a quick break to hear some short but very poignant wisdoms from a book.
Step 4: More Sanding
We roughed up the surface enough to have no more shiny spots. Now we continue to smoothen and frost our surfaces to perfection.
Note: this takes a long time and is pretty hard on the body. If you have a sand blaster, I highly suggest using it for quicker and better results.
We have a be nice policy.
Please be positive and constructive.
