Efflorescence Removal

Efflorescence is the white, powdery deposit that appears on masonry surfaces when water-soluble salts migrate to the surface and crystallize. While not structurally harmful itself, efflorescence indicates moisture movement through masonry and can be a persistent aesthetic problem.

Professional efflorescence removal involves proper cleaning techniques that remove deposits without damaging the underlying masonry. Simple brushing may work for light efflorescence, but heavier deposits often require chemical cleaners specifically formulated for masonry.

Effective treatment goes beyond cleaning to address the moisture source causing efflorescence. This may involve improving drainage, repairing mortar joints, waterproofing treatments, or modifying sprinkler systems that wet masonry surfaces.

Recurring efflorescence indicates an ongoing moisture problem that will continue until the water source is eliminated. Professional assessment helps identify why moisture is moving through the masonry and what corrections will provide lasting results.

Prevention strategies include proper material selection, adequate curing of new masonry, drainage improvements, and breathable waterproofing treatments. New construction should incorporate moisture barriers and weep systems designed to manage water without allowing salt migration.
