MasonryDefender Concrete Sealer – Deep Penetrating Silane Siloxane (1 Gal)

Clear, invisible protection for concrete

Experience clear protection for concrete without altering its natural appearance. MasonryDefender Concrete Sealer penetrates deeply to shield driveways, sidewalks, and patios from water intrusion and weathering, while preserving the surface look and texture you rely on daily.

How it works

Powered by a silane-siloxane formulation, the sealer bonds with the surface to form a hydrophobic barrier. Water beads and rolls off, yet the concrete remains breathable so moisture can escape naturally.

Key benefits at a glance

• Clear, non-glossy protection for driveways, sidewalks, and patios without color change
• Water beading and repellency while maintaining breathability
• Durable outdoor defense against pitting, cracking, ice melt salts, chloride ions, freeze-thaw cycles, and efflorescence
• Easy application and reliable coverage: clean the surface, apply with a low-pressure sprayer, 90–150 sq ft per gallon
• Breathable penetrating formula that protects beneath the surface without a film

Application tips for best results

• Prepare by thoroughly cleaning the concrete before sealing
• Use a low-pressure garden sprayer for even coverage and avoid pooling
• Allow sufficient time for penetration and cure under local outdoor conditions

Real-world use cases

Ideal for homes with exterior concrete facing seasonal moisture and de-icing salts. The breathable seal helps preserve the natural texture and color while reducing the appearance of mineral deposits over time.

• Driveways and sidewalks that endure freeze-thaw cycles
• Patios and outdoor spaces exposed to rain and salt exposure
