No-Fade Chalk Lines

I’ve been installing tile for 20 years. I always start a job by snapping a series of layout chalk lines on the area to be covered. Then I spray the lines with a clear coat of polyurethane. That way I can walk on the lines or sweep over them and they won’t fade or disappear. — Sissy Mcalpin

See how to use chalk lines perfectly.
