Sealing your Driveway
If you are installing a new asphalt driveway, do not seal it for at least six to nine months. Asphalt has light oils that need to evaporate before the driveway hardens completely.
If you choose concrete – especially colored concrete – you will want to seal it to prevent cracks, stains and water damage.
Step 1. Let the Concrete Cure
Freshly poured concrete cannot be sealed. It must cure for 21-30 days prior to application of a penetrating sealer.
Step 2. Clean the Driveway
Broom off any loose debris such as dirt, mud and leaves off of the driveway. If there are any oil or grease stains, these should be removed to the best of your ability with a pressure washer.
Step 3. Allow the Concrete to Dry
Water-based siloxane sealers need to have the concrete dry for 24 hours prior to application. No rain should fall within this 24 hour time period. This will reduce the dilution of the siloxane sealer and ensure that the maximum amount gets into the concrete substrate itself.
Step 4. Spray, Roll or Brush on the Sealer
It doesn't really matter which method of application is used, but of course a roller is faster than a brush and a pump up garden sprayer is faster than a roller. No other special equipment is needed. You do not need to worry about getting it onto plants or grass. If any gets onto metal or windows, wash it off immediately with soapy water and a sponge. Apply only enough concrete sealer that a slight whitish color is seen. Any ponding of material should be spread evenly prior to drying.
Step 5. Keep Rain and Traffic off of it for 24 hours
The sealer will dry in 1-4 hours but it is a good idea to keep cars and traffic off of the driveway for 24 hours. Application should occur when rain is not in the forecast for 24 hours after application to give the sealer plenty of time to penetrate and seal.
Once cured the siloxane sealer becomes a bonded component of the concrete driveway. A properly sealed concrete driveway will give years of protection from damage. The return on investment will be worth the time and expense of application.
