Concrete takes 28 days to fully cure and most concrete sealers require that the concrete is cured before sealing. There are however some sealers, referred to as Cure and Seals, that are designed specifically for concrete 2-28 days old. They are acrylic based sealers that contain Styrene and the Styrene makes the acrylic more resistant to moisture. Cure and Seals aid in the proper curing of the concrete, and they help to protect the concrete while curing.

  • Armor WB15: Water based low gloss cure and seal.
  • Armor WB25: Water based high gloss cure and seal.
  • Armor LV25: Solvent based high gloss cure and seal

Aside from cure and seals, there are also a few types of sealers that can be applied to new cSealing New Concreteoncrete, but won't help the concrete cure. If you want to seal your concrete before it is fully cured, but don't want to maintain a coating, then you can use a penetrating sealer.

  • Armor SC25: Silioncate water repellent sealer for new and existing concrete.

You do not have to use a cure and seal, but it is important to seal your concrete. Whether you want to cure in in the first 2-28 days, or wait six months, that is entirely your preference. Sealing your concrete will protect it against damage and deterioration against water absorption and surface abrasion. Sealed concrete is more resistant to:

  • Cracking, spalling, and pitting
  • Freeze-thaw and salt damage
  • Staining
  • Mold and mildew
  • Efflorescece
  • Dusting
  • Deterioration caused by surface abrasion
  • Deterioration caused by water absorption

If you are sealing concrete that is fully cured, you have the freedom of choosing which type of sealer you would like to apply. Many people will use a silicate sealer to increase the strength of the concrete, while others choose a water repellent sealer for defense against freeze-thaw damage and salt. The best type of concrete sealer for your concrete will depend heavily on what you want your concrete to look like once sealed, and how often you want to reseal. 

  • Silicate Concrete Sealers: Increase the strength and density of the concrete and reduce dusting and deterioration caused by week concrete and surface abrasion.
  • Silane Siloxane Water Repellent Sealers: Reduce the absorption of water and other liquids on the surface, and reduce deterioration and staining caused by water absroption. Sealed concrete is more resistant to freeze thaw and salt damage, mold and mildew, and eflflorescence. 
  • Siliconate Water Repellent SealersReduce the absorption of water and other liquids on the surface, and reduce deterioration and staining caused by water absroption. Sealed concrete is more resistant to freeze thaw and salt damage, mold and mildew, and eflflorescence. 
  • Acrylic Concrete Sealers: Enhance and protect concrete with a wet look, low gloss, or high gloss finish.
