Why Seal Paving?

Sealing both protects and beautifies pavers. How does it help?

  1. Sealing protects pavers against oil spills and other stains. This is especially important on driveways!
  2. Sealer that gets in-between the pavers helps hold the joint sand in place and resists mildew, insect attack and weed growth.
  3. Sealing intensifies colors and can give pavers a slight sheen.
  4. Sealant can protect pavers from UV rays, water and other natural elements, to keep the color as fresh as the day they were installed. Pavers lose their color without sealing, and after five years that color loss may be irreversible.
  5. Paver sealing prevents tyre tracks.
  6. Sealing makes pavers easier to clean.
  7. Sealing makes pavers tougher and more resistant to wear, by increasing their surface density.
  8. Sealing helps prevent efflorescence, that chalky white coating that sometimes appears on concrete.

The Professional Difference

Improper sealing can damage pavers at worst, and at best will not last long. At Pathwise, we are often called upon to fix the problems left by inexperienced or careless contractors or handymen. Our 25 years in the business gives us the knowledge and skills required for doing the best possible work. Some of the factors to consider are:

  • Different types of pavers require different products. The best sealant to use will depend on the porosity, location and wear of the pavers, as well as the aesthetic quality desired.
  • When pavers are oversaturated with sealer they may get a milky appearance after a few months. They can also become slippery and dangerous.
  • If pavers are not dry enough before applying sealer, again a milky appearance may be the result. Mold can also grow under the sealer, and moisture accumulated under the sealer may cause spalling, or surface peeling.
  • Improper preparation prior to sealing may cause your pavers to fade or weaken. Conversely, insufficient preparation could trap stains under the sealer.

Paver Sealing Process

Newly installed pavers around a pool or on a patio should be allowed to dry for about a week before sealing, so that moisture won't be trapped inside the pavers.

Driveway pavers may need more immediate sealing to avoid oil stains and tyre tracks.

Re-sealing begins with cleaning. A chemical wash starts the cleaning process, followed by pressure cleaning. This should remove most stains, dirt and old sealer. If pavers have been oversaturated with sealer, the process may need repeating.

If pressure washing has dislodged much of the sand in the joints between pavers, new sand should be applied. This keeps the pavers from shifting.

Depending on the weather, the pavers may have dried enough to seal the following day. One or two coats will be applied, depending on the porosity of the pavers and the type of sealer used. The sealer will harden enough in a few hours for pedestrian traffic, but cars should not drive on newly sealed pavers for at least 24 hours.

Paver Maintenance

The best thing you can do to maintain your pavers is to seal them properly. This will help prevent wear and tear and staining and will keep colours fresh.

The length of time a proper sealing with the right sealant will last depends on traffic and weather conditions, and on how often the pavers have been sealed previously. One test to see if your pavers need resealing is to run water from a hose onto the pavers. If the water does not bead up, it is time to reseal.

To keep your pavers in good condition, debris should be swept away regularly. Weeds that grow between the pavers should be removed.

Pavers can be cleaned by running water over the surface. A mild liquid detergent can then be applied and allowed to sit for ten minutes, without allowing the cleaner to dry. It is a good idea to test the cleaner on a small area first, to make sure the cleaner doesn't remove color or damage the surface. Ask us for our recommendations on the best cleaners to use for your pavers! After ten minutes is up, the pavers should be scrubbed with a nylon brush and rinsed thoroughly. Do not use a steel brush. Chemical cleaning or pressure washing should only be done by professionals at the time of resealing.

Inspect your pavers regularly. Lost sand should be replaced to prevent shifting.
