Flagstone Sealers

If your natural stone is currently unsealed and you want to maintain the natural, unsealed
look, you want a Silane-Siloxane water-repellent sealer like the Armor SX5000
or Armor SX5000 WB. These water-repellent sealers are designed to chemically
react below the surface to reduce the absorption of water and liquids on the
surface by up to 95%. Natural stone sealed with a water-repellent sealer is more
resistant to damage and deterioration caused by water, freeze-thaw cycles, and
de-icing salts.

The Armor SX5000 and Armor SX5000 WB are both
water-repellent sealers. The primary difference is that the Armor SX50000 WB is
water-based and the Armor SX5000 is solvent-based. While most customers prefer
the Armor SX5000 WB simply because water-based sealers are easier to apply, the
Armor SX5000 is a great choice for customers that prefer working with
solvent-based sealers.

If your natural stone is currently unsealed and you want a subtle color enhancement
without any gloss, the Armor WL550 is a great option. The Armor WL550 is a
water repellent sealer that chemically reacts below the surface to reduce the
absorption of water and liquids on the surface by up to 95%. Natural stone sealed with
a water-repellent sealer is more resistant to damage and deterioration caused
by water, freeze-thaw cycles, and de-icing salts.

The only way to achieve a low to high gloss finish is by applying an acrylic concrete sealer, but acrylic concrete sealers should not be used on natural stone. While some people may have success, the failure rate with acrylic sealers on natural stone sits at around 90%. The best sealers for natural stone are penetrating sealers like the Armor SX5000, Armor SX5000 WB, and Armor WL550.
