Concrete freeze thaw damage happens when water is absorbed into the concrete where it then freezes within the pores. Ice takes up more volume than water so when the water within the pores freezes, it expands causing the concrete to crack from within the pores. Concrete that has been damaged by freeze-thaw cycles will often have cracking, spalling, and pit marks on the surface.

If the concrete has already been damaged by freeze-thaw cycles you may need to apply a Densifier in order to increase the surface strength of the concrete and prevent any further deterioration that can be caused by abrasion. Densifiers will penetrate into the concrete and form a hardened crystalline barrier within the pores that will provide concrete with an up to 45% increase in strength. Densifiers aren't required, but if you are concerned about the strength of the surface consider applying the Armor S2000 or Armor L3000 Densifiers. After the Densifiers has been applied, follow up with the application of a water repellent sealer, like the Armor SC25 or Armor SX5000 to prevent further freeze thaw damage.

If you are looking to prevent freeze-thaw damage, or stop further damage to your concrete, you want to apply a Water Repellent sealer like the Armor SC25 or Armor SX5000. These sealers are designed to chemically react below the surface to form a hydrophobic barrier within the pores. This barrier will cause water and other liquids to bead off the surface, and reduce absorption into the pores. Concrete sealed with a water repellent sealer will experience an increased resistance to freeze-thaw damage, cracking, spalling, pitting, salt damage, and the growth of mold and mildew. Water repellent sealers like the Armor SC25 and Armor SX5000 are the most popular type of sealer used to combat freeze-thaw damage.

The last type of sealer that can be used to prevent freeze-thaw damage is a topical concrete sealer. Topical concrete sealers are designed to leave behind a visible surface film. Under this category, Acrylic Sealers are the most popular topical sealer used. Acrylic sealers, like the Armor AR350 Wet Look Sealer and the Armor AR500 High Gloss Sealer, will put a protective layer between the concrete and the water, snow, and ice. This type of sealer will need to be recoated every 3-5 years and can be applied alone, or over a water repellent sealer.
