How often you maintain your concrete driveway, walkway or patio depends on how much traffic it gets and the pollutant levels in your area. A pressure washer will take care of most normal wear and tear, but you may need to use special cleaning products if the concrete is heavily stained or discolored. Here are some more general tips for concrete care:
• Wash walkways and driveways at least twice a year to remove environmental pollutants that can speed up deterioration.
• Repair cracks as soon as they appear to deter water and weeds.
• Don’t use chemical deicers on driveways or walkways—they can eat away at the surface and cause major damage. Use sand on icy spots and simply sweep it up in the spring.
• Clean up spills as soon as they happen. Don’t try to use a hose to wash an oily spill; you’ll only spread it and create a bigger stain. Remove as much of the liquid as possible with kitty litter, cornmeal or any other absorbent material you have on hand.
• Sweep leaves and grass clipping off driveways, patios and walkways. The decaying vegetation can leave hard-to-remove stains on concrete and masonry.
• Don’t use your patio or driveway to repair your lawnmower or change the oil in your car. Gas and oil are difficult to clean up and can deteriorate some masonry materials.
• Keep weeds and tree roots from encroaching on your driveway, walkway or patio. Plants and tree roots are strong enough to break apart concrete and masonry.
• Have your concrete driveway sealed every few years to protect its surface from spills and stains.
• If your concrete or masonry is crumbling or otherwise seriously damaged, have it professionally repaired. A skilled contractor can repair the damage so it blends seamlessly with the existing surface.
