Cleaning and Sealing your Concrete Pavers
Why Should I seal my Pavers?
- It enhances the original color to give it a “Matte or Wet Look".
- It creates a seal over the top of the sand joint between the pavers to:
- Reduces the chance that the sand joint may be washed out by rain.
- Reduces the chance that a weed seed will germinate when it falls between the joints of the pavers.
- 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.
- Remove all material away from the top of the pavers.
- 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)
- 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.
- Power wash the solution off of the pavers.
Second day (the pavers must be dry to proceed)
- Refill the paver joints with jointing sand, sweep and power blow clean.
- Apply the Paver Protective Sealant at a rate of 30 ft. per liter.
- 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.
