If you recently pressure washed your paved driveway and notice that the joints seem loose and filled with grass, you need to take care of the problem before it snows. Loose driveway joints can cause all kinds of problems during and after the cold season ends, including lifting up your driveway. In addition, the grass can attract mold and mildew when the snow thaws. Here's an easy way to clean up and repair your driveway's loose joints.
Buy Your Sealant
Before you do anything to your driveway's joints, purchase a self-leveling sealant made with an acrylic base. The acrylic-based sealant reinforces your driveway's loose joints without cracking or pulling away after placement.
In addition, the sealant adjusts to the changes your driveway's joints experience during hot and cold weather. For instance, the joints expand during the summer's heat, and they contract or shrink during winter. Self-leveling sealant with acrylic accommodates both seasonal changes, which helps you avoid expensive repairs to fix cracks in your driveway.
Please not that if you have a brick driveway, you may want to leave this job to the pros. Brick driveways require you to cover a lot of ground and it may take awhile to fix each joint. Otherwise, keep reading to below to repair the joints of a cement driveway.
Get Rid of the Grass
First, use a patio broom to remove dirt and other stuck-on debris from the joints of your driveway. Next, use a garden cultivator tool to pull up the grass, or you can apply vinegar to the joints of your driveway to kill the grass permanently. If you choose to kill the grass, here's what you need to use and do:
- Pour 3-4 cups of white vinegar in a spray bottle
- Fill the rest of the bottle up with hot water
- Spray mixture on the grass until it soaks through to the ground beneath it — you want to kill the roots of the grass to prevent it from growing back in the joints
Give the vinegar's acid at least 24 hours to properly kill the roots and grass. Afterward, you can use the broom to sweep away the dead grass, or you can use your pressure washer to remove the grass instead. The pressure washer will also clear out any dirt that traveled between the joints overnight.
Now, it's time to place your joint sealant.
Place Down Your Sealant
Unless you purchased your sealant in a caulking container, you'll need to attach it to one. Once you have this done, carefully apply the sealant to the joints of the driveway. It's best to reinforce every joint to prevent any problems in the future. The sealant should dry within a day or so, but try to keep visitors and vehicles out of the driveway to make sure that it dries properly.
