The best water based paver sealer for your pavers will depend on what you want your pavers to look like once sealed. The three main types of water based paver sealers are penetrating water based paver sealers, low gloss water based paver sealers, and high gloss water based paver sealers.
Penetrating Water Based Paver Sealers
The best penetrating water based paver sealer to use on pavers is a Silane-Siloxane water repellent sealer. Silane-Siloxane water repellent concrete sealers penetrate into the surface of the pavers where they chemically react within the pores to create a hydrophobic barrer that won't change the look or color of the pavers. Water and other liquids will bead off of the surface of sealed surfaces, reducing damage and deterioration caused by water absorption such as cracking, spalling, pitting, freeze-thaw and salt damage, mold and mildew and efflorescence.
The two other types of water based sealers are siliconate water repellent sealers and silicate sealers. Siliconate water repellent sealers can leave behind a white residue when applied to pavers, and should be avoided. The same can happen with silicate sealers, only instead of a white residue, white crystals will form. The best penetrating sealer to use on pavers is a Silane-Siloxane hybrid sealer.
Low Gloss Water Based Paver Sealers
Low gloss water based sealers won't darken the pavers, but they will protect and enhnace them with a low gloss finish. The best water based low gloss sealer will be a low solids water based acrylic sealer.
High Gloss Water Based Paver Sealers
High gloss water based sealers won't darken the pavers, but they will protect and enhance them with a high gloss finish. The best water based high gloss sealer will be a high solids water based acrylic sealer.
