Thinking back on all the scrapes and bruises I acquired simply from falling down my stairs as an overly energetic kid, I cringe a little. But there was no stopping me, especially on the days (most) when I was late to school. If only my parents had thought to install some sort of no-slip system, I mightn't have been so black and blue. Luckily, I've found the answer to these painful falls, thanks to Martha Stewart [1].

Want to know the secret? Then .

By mixing regular paint with fine sand, you can safeguard your home against hazardous slips and falls. First, paint your stairs with regular paint. Then, tape off a striped area where you'll want
to use nonslip paint. Then mix two cups of paint with 3/4 cups of sand (from a craft or hardware store). Paint your stripes, let dry, then paint over it with a coat of regular paint. You probably won't want to use this trick on you foyer stairs, but your back or outdoor stairs will do.
