How long does concrete sealer last?
Epoxy and urethane systems last between 5-10 years, closer to 5 if the surface experiences heavy traffic. Reactive penetrating sealers are the longest lasting concrete sealers, wearing away only if the substrate surface itself wears away.
Does sealing concrete make it waterproof?
Penetrating Concrete Sealers
– This type of sealer penetrates into the surface, sealing out water and contaminates. Penetrating sealants work 100% below the surface to protect and waterproof your concrete from within, while still remaining breathable. These sealers do not form a film or change the sheen of the surface.
