spray paint (gloss white, reflective, and semi-gloss or flat black)
newspaper for masking
TechShop (for making template)
Step 1: Make a template
I used Corel Draw to sketch a 4" tall set of house numbers. I selected a font I liked, placed the numbers, then used Corel's convert to curves feature to get the outline of the numbers.
I originally cut them out in heavy paper, but decided I wanted a truly reusable set, as the numbers fade on the curb after a couple of years. Therefore I used a piece of scrap acrylic for the final version.
Step 2: Measure the curb for the template bend
Step 3: Cut the template out of acrylic, bend it to fit the curb
I marked the bend location, heated it up and then bent it. The cooling jig allows you to hold the part at a set angle until the plastic cools and sets. (The heat strip photo is from another project).
Step 4: Prepare the curb and paint a base coat
Spray a coat (or two or three) of the gloss white spray paint.
When it is dry, coat the base layer with the reflective coating paint.
