Sure Klean® Weather Seal H40 is a deep-penetrating water repellent and consolidation treatment for brick, most natural stone, unglazed terra cotta, historic concrete, stucco and cast stone surfaces. H40 protects against deterioration caused by water and waterborne contaminants while strengthening weathered surfaces and soft mortar joints. Weather Seal H40 also reduces the severity of biological staining common to regions with high relative humidity. It helps prevent the rapid recolonization of biological species such as mold, mildew and lichens that normally thrive on masonry and natural stone architecture.
ADVANTAGES
• Deep penetration provides long-lasting protection.
• Strengthens and protects deteriorating surfaces.
• Strengthens soft mortar – reduces need for repointing.
• Treated surfaces “breathe” – does not trap moisture.
• H40 helps prevent rapid recolonization by biological species such as mold, mildew and lichens.
• Low odor.
Limitations
• May damage glass or be difficult to remove. Always protect.
• May cause slight or moderate darkening on some surfaces. Always test for desired results.
• Surface and air temperatures should be above 40°F (4°C) and below 95°F (35°C). Avoid application on extremely windy days to avoid rapid evaporation of the solvent carrier.
• Not recommended for application to new concrete or below-grade application.
• Will not prevent water penetration through structural cracks, defects or open joints.
