Sure Klean^® Weather Seal H40 is formulated as a deep-penetrating water repellent and consolidation treatment for brick, most natural stone, terra cotta, historic concrete, stucco and cast stone surfaces. H40 protects against deterioration caused by water and water-borne contaminants while strengthening weathered surfaces and soft mortar joints.

Manufactured and marketed in compliance with USEPA VOC regulations (40 CFR 59.403).

• Deep penetration provides long-lasting protection
• Strengthens and protects deteriorating surfaces
• Strengthens soft mortar -- reduces need for repointing
• Treated surfaces "breathe" -- H40 does not entrap moisture
