How To Seal A Paver Patio

Sealing a paver patio is easy, and can be done in just a few simple steps. How you seal a paver patio will depend on the type of paver patio sealer you are using.

How to Seal a Paver Patio with a Penetrating Sealer

Penetrating sealers are designed specifically for use on unsealed pavers. In order for the sealer to properly penetrating, there can’t be any existing sealers or coatings on the surface. The best penetrating paver patio sealer to use is a Silane Siloxane water repellent sealer, like the Armor SX5000 or SX5000 WB. They penetrate into the surface of the patio pavers where they chemically react to form a water repellent barrier within the pores, causing water and other liquids to bead off the surface. These types of patio paver sealers are designed to protect the pavers against deterioration and staining caused by water absorption, without changing the look or color of the pavers. They also help to reduce the growth of mold, mildew, algae and the formation of efflorescence.

  • Armor SX5000 (solvent based)
  • Armor SX5000 WB (water based)

What’s the difference? The Armor SX5000 and Armor SX5000 WB are both high solids DOT approved water repellent sealers. The only difference between the two is that one is suspended in water and the other in solvents. Which sealer is best for your patio pavers will depend entirely on whether or not you prefer water or solvent based products. The SX5000 WB is very popular on patio pavers because it has little to no odor.

Appling a water repellent sealer to patio pavers is very easy:

  • First, make sure the pavers are clean and free of anything that could prevent proper penetration. You can use water or a pressure washer. If a cleaning chemical is used, make sure that any residue from the cleaner has been removed, and if required, the patio substrate PH has been neutralized. Most patios simply require the use of a pressure washer.
  • Next, allow the pavers to dry for at least 24 hours before sealing. You want the pavers to be as dry as possible before sealing. Even if they look dry, moisture can be trapped in the pores.
  • You can use a roller, but penetrating sealers are best applied with a commercial pump sprayer. You want to apply 2 coats for even coverage.
  • Let dry. Keep the surface dry for at least 36-48 hours after sealing.

The Armor SX5000 and Armor SX5000 WB will need to be reapplied every 7-10 years.

Another option is the Armor WL550. It offers many of the same benefits as the Armor SX5000 and Armor SX5000 WB, but it contains resins that will slightly darken the look of the pavers. It won’t leave a visible surface film or coating, but it will slightly enhance the pavers and offer the same benefits as a water repellent sealer. The application is very similar, but the Armor WL550 needs to be applied every few years to maintain the color enhancement.

How to Seal a Paver Patio with a Wet Look, Low Gloss, or High Gloss Sealer

If you want a wet look, low gloss, or high gloss finish then you want an acrylic sealer. Acrylic sealers are designed to enhance pavers with a wet look, low gloss, or high gloss finish, and provide complete protection against deterioration caused by water absorption and surface abrasion. Acrylic sealers are available in water based and solvent based formulas. The water based acrylic sealers will provide a gloss without darkening the surface of the pavers, while solvent based acrylics will darken the surface of the pavers to bring out any dull and faded coloring, and enhance with a gloss.

  • Solvent Based Acrylic Sealers: Armor AR350, Armor AR500, Armor AX25, Armor LV15, Armor LV25
  • Water Based Acrylic Sealers: Armor WB15, Armor WB25

Applying an acrylic sealer to patio pavers is very easy:

  • First, make sure the pavers are clean and free of anything that could prevent proper penetration. You can use water or a pressure washer. If a cleaning chemical is used, make sure that any residue from the cleaner has been removed, and if required, the patio has been neutralized. Most patios simply require the use of a pressure washer.
  • Next, allow the pavers to dry for at least 24 hours before sealing. You want the pavers to be as dry as possible before sealing.
  • Using a roller or sprayer, apply the first coat of the acrylic sealer. The acrylic sealer should be applied in the late afternoon or early evening for optimal curing.
  • A second coat is always suggested. Pavers are very porous and tend to soak up a lot of material. In many cases, one coat will leave you with an uneven finish. Water based acrylic sealers have a very specific recoat window, but solvent based acrylic sealers can space the coats out 24 hours. It is important to note that if it is your first time sealing your pavers, a third coat may be required in order to achieve a higher level of gloss.
  • Let dry. The acrylic should be kept dry, and free of any foot or vehicle traffic, for at least 36-48 hours.

Acrylic sealers should be reapplied every 1-3 years to maintain a consistent gloss level.
