How to seal pavers
Choose a water-based sealer if your pavers are laid with joint sand.
Water-based sealers are sprayed on and give an even coverage. The main benefit of a water-based sealer is that it hardens the joint sand and penetrates into pavers better.

However, they keep your putty dry and helps seal the bond between pavers.; -This ends up creating a hard seal over the entire paved area. Water-based sealers do not darken the stones or give a high amount of shine to the pavers.; -It also provides a nice polish over soft rock surfaces. Even if your pavers are laid with joint sand, make sure to choose non-sand sealers.; -Require a vocals sealer if your pavers are laid in sand for more than a year. If you have carpeted pavers, they require a professional sealer.;
