If used correctly, you should not need to reapply for 15 years or more (this product comes with a 15-year waterproofing warranty). The Green Building Supply Penetrating Concrete Sealer penetrates deeply, protecting concrete from within rather than just coating the surface. As an effective concrete moisture sealer and indoor concrete sealer, it won't wear away. To test, simply pour water on the surface—if it beads up, the sealer is still working.
