Masonry Sealer

Masonry sealers provide invisible protection against Ontario's harsh weather, but choosing the wrong type can trap moisture and accelerate deterioration—making professional selection critical for long-term protection. Breathable penetrating sealers allow water vapor to escape while repelling liquid water, essential for older buildings with moisture from interior sources. Film-forming sealers create surface barriers appropriate for some applications but can cause spalling if moisture becomes trapped. Silane/siloxane sealers penetrate deep into masonry pores, providing 10+ year protection against water and chloride intrusion from road salt. Application timing matters—sealers applied to damp masonry or before repairs waste money and trap problems. Different brick types require specific sealers; soft historic brick needs different treatment than modern hard-fired units. Fix My Brick selects appropriate sealers based on masonry type, exposure conditions, and moisture sources, ensuring protection without unintended consequences. Professional application with proper surface preparation ensures maximum penetration and longevity.
