While both paver sealing options work equally well in protecting your outdoor space from moisture penetration, the biggest difference lies in their application. Oil-based sealers tend to be less expensive than acrylic and are easier to apply, but you will need to reapply them every now and then as they wear off easily with rain or foot traffic. On the other hand, an acrylic paver sealing option is a water-based sealer that doesn’t leave a harmful residue on your pet’s paws.
