After precast restoration it is critical to seal the precast surface of the stone in order to help prevent precast leaching and water penetration. If the precast is not sealed, it acts as a sponge, and creates a breeding ground for biological growth. Precast sealing also seals in the pores of the stone so that water is not able to freeze and thaw within the stone creating precast spalling.
If the precast contains spalling, it is important to address the precast spalling with caulking or precast patch prior to sealing the precast in order to provide a water tight barrier.
