The best type of sealer to use on stucco is a penetrating water repellent sealer. Water repellent sealers are designed to penetrate through the surface of the stucco where it will chemically react within the pores to form a hydrophobic barrier that will caused water and other liquids to bead off the surface.

Benefits:

• Reduce cracking, spalling, and pitting caused by surface water absorption

• Reduce the growth of mold and mildew on the surface

• Reduce the formation of efflorescence

• Reduce freeze thaw and salt damage

• Reduce premature deterioration caused by surface water absorption
