Tire marks can generally be removed from a concrete driveway by cleaning the area with a degreaser. If the marks are embedded deeply into the sealant on the driveway, then a solvent is used to loosen the sealant, allowing it to be cleaned. Stripping the sealant is also an option.Know More
Tire markings are caused by hot tires running over the sealant applied onto the concrete driveway. The sealant contains plastizers, which are added to the tires to make them flexible. As the tires are used, the plastizers heat up, which allows them to leech from the tires. When the leeching plastizer comes into contact with certain sealants used on concrete driveways, they migrate, discoloring the sealant and causing the tire marks. The higher the quality of the tire, the more plastizer tends to be present in the tire formula, making them more likely to cause marking.
To prevent the tire marks from appearing, car owners can switch to harder, lower-costing tires. Driveways can also be covered with denser sealants that are more resistant to marking. These denser sealants are those with greater cross-linking in the resins used. Sealants that are most resistant are the higher-solids acrylics, epoxy sealers or cross-linked polyurethanes.Learn more about Outdoor
