How thick do I apply the paint or clear coat layer?
According to Matthews Paint Company, it is specified that clear coats and/or paints should have the same amount of coating (4 mil wet/2 mil dry).
What is a Wet Film Gauge?
A Wet Film Gauge is the most accurate way to measure the thickness of the paint coating when it is first applied to a surface or substrate.
I am using a photopolymer sheet as a lens in a curved sign with a digital print. Do I need to apply a clear coat even though it is an interior application?
Yes. Regardless of the application (Interior/Exterior), a top coat must always be applied over the photopolymer. This is true for all sub surfaced painted signs, signs with sub-surface digital graphics, and materials that incorporate color or patterns in the base substrate.
