Tire skid marks on a concrete driveway are much more visible than on asphalt, and they give your driveway a neglected look. Braking suddenly at high speed, locking the car wheels, is the most common cause of these black lines, and although vehicles are usually moving slowly in and out of a driveway, skid marks can still happen. Follow these tested steps to remove these blemishes from your concrete driveway, and learn how to prevent them in the future.
Prepare the Yard Near the Driveway
Remove container plants and cover any flowerbeds and pathway lights near the skid marks with a lightweight plastic tarp, weighted with bricks or rocks. Move any toys or bicycles off the driveway as well.
You will also want to prepare yourself at this point in time, to stay as dry as possible. Eye protection, rubber gloves, and waterproof boots should be enough gear for this job.
Rent or Borrow a Hot Water Pressure Washer
You will need a hot water pressure washer rated up to 3000 psi to remove solid rubber marks from the concrete surface. Concrete should be rated to withstand pressure to 4000 psi, a standard for driveways, so you won't have to worry about damaging the surface. Spray the skid marks for two to three minutes with the water hot enough to produce some steam.
Soak Marks with Industrial-strength Degreaser
You can get industrial degreasing detergents at your hardware or auto supply store. Apply it to the skid marks and let it soak in for 10 minutes.
Using the bristle broom, scrub over the tire marks to lift the rubber particles. Rinse your broom from time to time as you scrub, and be sure to brush around the edges of the skid mark to ensure you have cleaned it all off.
Rinse the Sites
Adjust the pressure washer to a lower temperature, warm but not steaming, and rinse off the skid mark areas. Then, point the pressure washer nozzle down the driveway toward the road, not toward your lawn and flowerbed, and finish with a rinse at the coolest setting.
Squeegee the Driveway
With the squeegee, pull as much water from the concrete as you can. Allow the driveway to dry for three to four hours afterward, and park cars on the road.
Cover the Concrete with a Penetrating Sealant
Purchase a clear, penetrating concrete sealant for your driveway. Apply it when the surface has dried fully, using the squeegee. Create an even layer of sealant over the entire thing to shield it from future skid marks. Avoid using a film-forming sealer, because these create a slippery surface and can alter the color and appearance of your concrete.
Teach Your Family Drivers How to Avoid Skidding
Explain to the drivers in your family the negative effects of tire marks, and how it can impact your vehicle. This poor braking technique can cause brake wear, tire damage, and even collisions in wet weather with road objects and other cars. Show everyone how to brake properly and avoid ever having to clean the skid marks again.
