When talking about color-filling plaques, there are heavy sighs, raised eyebrows, and engravers who flat out refuse to use this technique. But there is new hope for the tedious task of color-filling when it comes to non-porous acrylic plaques.
In the past, engravers have used paper mask to cover the engraving surface, then spent hours “weeding out” the mask from the engraved design. But there is an easier way! When color-filling a non-porous plaque surface, such as AcrylaStone, do not use a paper mask. Use the following easy steps instead:
Step One: Engrave the design on the plaque surface; there is no need to engrave “too deep”. Some engravers have the misconception that deeper engraving is better.
Step Two: Apply paint to the plaque surface covering the engraved area. It is important to remember that if the plaque is to be used outside, an exterior-based paint such as Rustoleum should be used as the color-fill paint. If the plaque is interior, any acrylic-based paint will normally work just fine.
Step Three: After the paint has dried, sand the surface of the plaque using a random orbital palm sander and a 320 grit or higher sanding disk. This will remove the paint from the surface of the plaque, but not the engraved areas. Using 600 grit or higher will result in a more polished finish.
