The best sealer for pavers will depend on whether or not your pavers are currently sealed, what you want your pavers to look like once sealed, and why you want to seal your pavers. The two most common paver sealers are water repellent sealers and acrylic sealers.

Water repellent sealers are penetrating sealers. They work entirely below the surface to cause water and other liquids to bead off the surface. They will not change the look or color of the pavers, and they will not leave behind a visible surface film. Pavers sealed with a water repellent sealer are protected against staining and deterioration caused by water absorption, snow and ice, freeze thaw cycles, mold and mildew, and efflorescence. Water repellent sealers are the best paver sealer to use if you are looking for a long lasting, easy to apply sealer that won’t change the look or color of the pavers.

Acrylic sealers are sealers that enhance the surface of the pavers will a wet look and low to high gloss finish. They are also designed to stop deterioration and staining caused by water absorption and surface abrasion. Pavers sealed with an acrylic sealer can be slippery when wet, but non slip additives are available and can be added directly into the top coat. Acrylic sealers are great to use if you want to enhance dull or faded pavers, protect the color of the pavers, or enhance the pavers with a wet look, low gloss, or high gloss finish.

If your pavers have been sealed in the past, or if you are recoating your pavers, you want to make sure that the new sealer is compatible with the old sealer.
- Silicate Sealer: Silicate sealers can typically be recoated with a water repellent sealer or an acrylic sealer so long as the silicate sealer has been down for at least 7 days. Like with all products, a test area should always be applied to verify compatibility.
- Water Repellent Sealer: If it has been 3-5 years since the water repellent sealer has been applied, you are typically free to reseal with another water repellent sealer or an acrylic sealer after a test area has confirmed compatibility. If it has been less than 3 years, or if water still beads off the surface, you may be able to apply a solvent based water repellent sealer or a solvent based acrylic sealer so long as it has been approved by the manufacturer of the acrylic, or after a test area has been proven compatible.
- Acrylic Sealer: If you pavers were previously sealed with an acrylic sealer, and there is still acrylic sealer on the pavers, you want to be consistant in recoating. Water based acrylic sealers need to be resealed with a water based acrylic sealer, and solvent based acrylic sealers need to be resealed with a solvent based acrylic sealer. Mixing water and solvent based acrylic sealers can result in coating failure.
