There are several factors that contribute to how long a concrete sealer actually lasts for, but there is a general average for most Foundation Armor concrete sealers.
- Silicate Concrete Sealers: Silicate concrete sealers, like the Armor S2000 and Armor L3000, never break down. They spark a chemical reaction in the concrete in order to form a calcium silicate hydrate structure within the pores. Once that structure is formed, it can only be removed if the concrete itself is removed.
- Silane Siloxane Water Repellent Sealers: Silane Siloxane sealers, like the Armor SX5000 and Armor SX5000 WB will last for up to 7-10 years below the surface.
- Siliconate Water Repellent Sealers: Siliconate sealers, like the Armor SC25, will last for up to 5-7 years below the surface.
- Acrylic Concrete Sealers: Acrylic sealers, like the Armor AR350 and Armor WB25, will last for up to 1-3 years on an exterior surface before the need to recoat.
- Epoxy Coatings: Epoxy coatings, like the armor Epoxy, can last for up to 10 years before the need to recoat.
- Urethane Coatings: Urethane coatings, like the Armor UTN60 or Armor UTX60, can last for up to 10 years before the need to recoat.
There are several factors that contribute to the actual life of a concrete sealer:
- The number of coats applied. This is actually a very important factor. Unless the sealer specifically requires 1 coat, most sealers should be applied in two coats to ensure proper penetrating and coverage. Under applying a product will result in a shortened life and lack of performance.
- How the product was applied. Properly applying a product is crucial to product life and performance. If a product is not properly applied, it will result in a shortened life and lack of performance.
- The current condition of the substrate. There are some issues a sealer or coating can’t fix. If concrete is filled with cracks, is showing signs of deterioration, has excessive efflorescence, etc., other steps may need to be taken before a sealer or coating can be used.
- The environment in which the sealer was applied. The harder a product has to work, the faster it will break down. If a product is constantly exposed to high temperatures and UV rays, it may need to be recoated sooner than a product that is applied to a shady patio where the high temperature only reaches 70. Same goes for interior coatings. If there are dozens of fork trucks going over a warehouse floor, the coating will break down faster than a coating that was applied to a residential 2-car garage.
- The suitability for the project. Choosing the right sealer is one of the most important factors in achieving optimal life. Sealers and coatings are designed for specific uses, and uses products in the application they are designed for helps to ensure proper performance and an extended life.
- Not properly preparing the surface. Surface preparation is one of the most important factors that impacts both life and performance. Properly prepared surfaces help to determine penetration and bond which are directly connected to life and performance.
