The Social Security Act was signed into law by President Franklin D. Roosevelt at the White House on this day in 1935. If you're expecting guests at your house this holiday weekend, you need to provide them some "social security" if your concrete patio steps or walkways are too smooth and slippery. Here's an easy surfacing trick: Super-smooth concrete can be etched. Wearing safety goggles and rubber gloves, use a 25-percent solution of muriatic acid. This powerful chemical eats away the thin top layer of concrete, exposing the sand that was originally mixed into it. This procedure leaves a slightly rougher surface, one similar to fine-grit sandpaper. It provides better traction underfoot -- even when it's wet. Simply pour it on, let it stand for 10 or 15 minutes, and rinse it off carefully -- using a garden hose. To make the surface still a bit rougher, repeat the process until it's exactly how you want it. Consider it social security for those you love. And that's the On The House Tip for today.
