When we moved into our current house, (almost six years ago) I noticed cracks in the concrete driveway. Not just expansion joints, but cracks and a few small holes. I got to reading how water can freeze and plants can grow in the cracks and make them bigger. If these cracks and holes are not maintained properly, it can result in irreversible damage. I originally used a special silicone caulk made for sealing concrete and masonry. It worked but, after a year, it started coming out of the cracks. The caulk cost about ten dollars a tube and I thought I would try hot glue instead. The hot glue has held up over two years. In this Instructable I will show you how I use hot glue on the expansion joints, cracks, and small holes in my concrete driveway.

Step 1: Tools and Materials

You only need a few tools for this job. A hot glue gun with hot glue sticks. A screwdriver or something strong to scrape dirt and plants out of the cracks. An old tooth brush or steel wire brush are useful for getting the cracks and holes clean. You should wear safety glasses and gloves.

Step 2: Scrape Out the Dirt and Plants

Use the screwdriver to scrape the dirt and plants out of the cracks. You could spray water in the crack to get it really clean, just let it dry before applying the glue.

Step 3: Use the Hot Glue Gun

Once your crack is clean, use the hot glue gun to apply a bead into the crack. You want the glue to fill the crack to the top. The goal is to keep dirt and water out of the crack.
