FEATURES: MasterProtect H 400 is a clear, water-based, 40% silane  (alkylalkoxysilane) penetrating sealer with traffic bearing qualities.

  • Water based, VOC compliant (Except S. Calif SCAQMD)
  • Excellent penetration
  • High moisture repellant
  • Breathable
  • Transparent, non-staining
  • One component

Provides long-lasting protection against moisture intrusion, freeze/thaw cycles, and chloride intrusion.

Ideal for traffic-bearing surfaces.

YIELD (typical)

Concrete: 100 – 200 ft2/gal (2.4 – 4.8 m2/L)

Brick: 100 – 200 ft2/gal (2.4 – 4.8 m2/L)

Always apply a test area to determine actual coverage rates. Coverage rates will vary greatly with the porosity of the substrate

APPLICATIONS

  • Parking garages
  • Stadiums
  • Bridge decks
  • Concrete highway road surfaces
  • Ramps and barrier rails
  • Stadiums
  • Cooling towers
  • Many other reinforced concrete structures
  • Brick Pavers
  • Unglazed Tile
  • Chimneys
  • Hard Burnt Brick
  • Stucco
 
LOCATION
  • Horizontal and vertical
  • Exterior or interior
  • Above grade SUBSTRATE
  • Concrete substrates: architectural, glass-fiberreinforced, precast, cast in place, slicia fume
  • New and existing concrete
APPLICATION:
 
1. Verify substrate has properly cured. Concrete should obtain 80% of design strength, typically achieved within 14 – 28 days.
2. Clean concrete surfaces of all sand, surface dust and dirt, oil, grease, chemical films and coating,s and other contaminants prior to application. Use waterblast, sandblast, or shotblast as necessary to achieve the desired surface condition.
3. Surface, air, and material temperatures should be 40 to 110° F (4 to 43° C) during application. Do not apply Enviroseal® 40 when temperatures are expected to fall below 40° F (4° C) within 12 hours.
4. Surfaces to be treated can be slightly damp; however, a dry surface is suggested for maximum penetration of sealer. Do not apply Enviroseal® 40 if standing water is visible on the surface to be treated.
5. Crack control, caulking, patching, and expansion joint sealants can be installed before or after application of the sealer.
6. Allow a minimum of 6 – 12 hours curing time for caulking and sealant materials (or until they have skinned over) before applying Enviroseal® 40.
