How to Seal Concrete Driveways

Concrete driveways are under constant attack from vehicle traffic, weather conditions, water and deicing salts in cold-winter areas. Your driveway is one of the first things visitors see as they approach your home; keeping it maintained and sealed gives a better appearance and helps prevent the surface breaking down over time. You can seal your concrete driveway yourself, using a penetrating, siloxane water repellent, which provides protection even below the concrete's surface.

Broom
Hose
Power washer
Gloves and protective clothing
Siloxane sealer
Brush, roller or garden sprayer
Sponge
Soap

Instructions

- 1
  Check the local weather forecast; be sure no rain is expected in your area the day you will be applying the sealer and for 24 hours afterward.
- 2
  Sweep your driveway thoroughly, removing any mud, leaves or debris, and then hose down to remove dust. If there are oil or grease spots, a power washer will help remove them. Let your driveway dry for 24 hours.
- 3
  Put on long sleeves, pants and gloves before getting to work. Your skin should be protected from the sealer.
- 4
  Apply the sealer using a brush, a roller or a garden sprayer. Any of these will get the job done, but a sprayer will make the work faster and easier.
- 5
  Spray a small section at a time, applying sealant in thin, overlapping coats. Apply just enough to see a slight whitish color. Do not overapply. If the sealant forms puddles, spread them with a brush before they dry.
- 6
  Wipe sealant off metal or glass immediately, using a sponge and soapy water.
- 7
  Keep cars off the driveway for 24 hours.
