If you like the look of your unsealed concrete, brick, pavers, or natural stone, then you want to use a water-repellent sealer like the Armor SX5000 WB (water-based) or Armor SX5000 (solvent-based). Water repellent sealers help to protect the substrate against damage and deterioration caused by the absorption of water, snow & ice, and freeze-thaw and salt damage.
