The house numbers that we painted on the curb are showing their age. So we decided to repaint them. I scraped the old surface to get off any loose paint. Then I spray painted the rectangle underneath the numbers to white. Stencils were used to spray paint the numbers on black.
But the curb curves, and the stencils don't so there was a lot of over/under spray and the numbers looked fuzzy. I tried to sharpen things up with a little paint brush and paint from the spray cans, but spray can paint is very thin and runny. When I put paint to the curb with the brush, it tended to run down the curb, thru the numbers.
So I decided we needed actual paint. In a can. Oil-based enamel outdoor paint. Bought one quart can of white, one of black, from Home Depot. Using another brush I touched up the number I had sprayed. Took two days -- one to touch up the white, then another to touch up the black, then another to touch up the white that had drips of black, and another to touch up the black that had drips of white.
To save trouble with the other number on the other side of the driveway, I just went straight to the touching up with the can paint, since I could still see where the number was from the last time.
And while I was at it, I did the same for the neighbors at 10603.
