Two choices exist for finishes when sealing pavers: a glossy “wet-look oil-base” or a “water-base natural-look.” The “wet-look oil base” is NOT recommended by Pavestone. If a wet-look sealer is applied with even the smallest amount of moisture or water in between the paver joints or on the paver, it may leave you with a white haze on the pavers which becomes very difficult to remove and in some cases, may cause the pavers to be replaced. The “wet-look sealer” is typically an oil-based solvent and will NOT mix with a water-based sealer. However, if your existing pavers were previously sealed with oil, then an oil-based sealer should be reapplied.
