Driveway Sealants

Applying a sealant to protect your driveway from cracking in cold, wet weather is simple and cost-saving preventive maintenance. You can also use the sealer to add color or glitter to fancy up your home.

Here are some tips to get you started:

  • Pick a sealer for your type of driveway (concrete or asphalt), although many will seal either type. Most sealers are clear, but you might consider one with color or glitter.
  • Determine how much sealant to buy. Sealant comes in various sizes, the larger ones being 5 gallon buckets that typically cover 300 square feet. You may need more sealant if your driveway has a rough surface or if you will need to apply a second coat.
  • Buy a squeegee to apply the sealant. The other side of the squeegee should have a brush for driving the sealant into cracks.
  • Inspect the surface to confirm that any cracks are less than about an eighth of an inch in width. Fill any large cracks before sealing the drive. Crack filler ranges from liquids designed to fill small cracks to coarse, to a caulk-like putty for medium cracks, to aggregate filler (sometimes called cold patch) for large cracks. Check the manufacturer's recommendations for what tools may be needed.
  • Clear your driveway of oils stains, debris, and leaves and keep pets away.
  • Wear old clothes and shoes. Some people wrap their shoes in plastic bags (from the grocery store) that they throw away after the job is done.

The application of the sealant is quite simple. Pour out some sealant onto the

driveway and spread it with the squeegee as uniformly as possible. Once the sealant is spread out, use the brush side of the squeegee to force the sealant into the smaller cracks and to remove any ridges. Repeat the process until you have covered the area you want to seal.
