Sikagard H 1000 – 100% Silane Penetrating Water-Repellent Sealer (5 Gallon Pail) (Formerly MasterProtect H 1000)

Sikagard H 1000 (formerly MasterProtect H 1000) is a high-performance, 100% silane penetrating sealer formulated to deeply impregnate concrete, masonry, and architectural surfaces for long-term protection against moisture intrusion, chloride penetration, and freeze/thaw damage. Its reactive silane chemistry bonds within the pores of the substrate to create an invisible water-repellent barrier without altering surface appearance.

Sikagard H 1000 is breathable — allowing interior moisture to escape — and remains transparent, making it ideal for horizontal and vertical surfaces, above-grade concrete, precast, masonry, bridges, decks, parking garages, ramps, barrier walls, and other traffic-bearing or architectural concrete. The sealer does not require masking of windows or special cleanup, and is suitable for solvent-based application in cooler weather conditions.

Benefits

• Deep-penetrating 100% silane formula for long lasting water and chloride protection
• Breathable, non-film forming, and clears — preserves original concrete/masonry appearance
• Effective on horizontal or vertical surfaces; suitable for traffic-bearing surfaces including decks, garage floors, sidewalks, ramps, etc.
• Reduces water absorption, helps protect against chloride/salt ingress, freeze/thaw damage, efflorescence, and environmental staining
• Clear and non-staining — safe for glass windows, metal frames, and painted surfaces during application
• Easy one-component application — no mixing required

Applications

• Bridge decks, concrete ramps, parking garages, barrier walls, sidewalks, exterior architectural concrete and precast, and traffic-bearing decks
• Concrete, precast, masonry, stucco, brick surfaces — interior or exterior, horizontal or vertical, above-grade only
• Structures exposed to de-icing salts or chloride environments (bridge decks, coastal/marine, parking garages, etc.)
• Architectural concrete facades, masonry walls, decorative concrete, where appearance maintenance is important
