This is nothing earth shaking. I’m just trying to decide how best to paint two new brick structures that I just finished. The brick material itself is made by Rusty Stumps and is a laser engraved board that is thin and stiff. It has been laminated to heavier stock underneath because the brick sheet is about .030 in thickness. In the past I have used two different methods in painting vacuum formed plastic brick. I call them positive and negative. What I mean by ‘negative’ is that I prime, then paint the red brick color. After that dries, I wash the mortar color over the brick and then clean off the brick surface by wiping off the excess. This method leaves the mortar color in the groves. The ‘positive’ method is paining the mortar color first which can also be the primer. After the mortar color has dried, then the brick color is carefully dry brushed across the sheet, hopefully touching only the raised portion which is the brick. There is another variation of this and that is to use a large flat rubber eraser. Smooth out a thin layer of color on a plastic or glass sheet and press the eraser surface into the color, then transfer the color to the brick similar to pad printing. This is a little tricky getting into corners but it works well on the main surfaces. I plan to test both methods on some sample material, but am wondering if there is yet another method out there that I don’t know about.??
