Cleaning and Sealing your Concrete Pavers

Why Should I seal my Pavers?

  1. It enhances the original color to give it a “Matte or Wet Look".
  2. It creates a seal over the top of the sand joint between the pavers to:
    1. Reduces the chance that the sand joint may be washed out by rain.
    2. Reduces the chance that a weed seed will germinate when it falls between the joints of the pavers.
  3. Protects against oil and dirt for easier cleaning.

When should I seal my pavers?
The pavers must be installed for at least 60 days before having them sealed, which allows the concrete to cure.  Your pavers should be sealed on a regular basis, in order to provide the protection they require.  Most applications normally last 2-4 years, and depends on the amount of traffic in the area.

Application Instructions
First day

  1. Remove all material away from the top of the pavers.
  2. Spot clean oil, rust, paint, tar and other stains. (Depending on the age of the stain, we may not be able to get the entire stain out)
  3. Do an efflorescence scrubbing bath on the pavers to prepare the surface for sealing.  It is a nitric acid solution (contains nitrogen, safe for your lawn and plants) which cleans away any efflorescence (salts) and dirt. 
  4. Power wash the solution off of the pavers.

Second day (the pavers must be dry to proceed)

  1. Refill the paver joints with jointing sand, sweep and power blow clean.
  2. Apply the Paver Protective Sealant at a rate of 30 ft. per liter. 
  3. You will be able to walk on the area within a few hours, but you must keep car traffic off your driveway for 24 hours after it has been sealed.
