MCI® POWR 100 Silane Water Repellant

MCI® POWR 100 is a silane water repellant containing time-proven Migrating Corrosion Inhibitors (MCI®) and an oleophobic additive.MCI® POWR 100penetrates deep into concrete, providing reinforcing steel with corrosion protection against the deteriorating influence of carbonation, chlorides, and other contaminants. The oleophobic additive prevents staining caused by motor oils, food, and other oily substances. Silane Water Repellents


MCI® POWR 100 is a two-part product which is sold in 5 gallon and 55 gallon kits. The two components of MCI® POWR 100 are mixed immediately prior to use. Any remaining mixed product should be used within 14 days. To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40 - 100 °F (4 - 38 °C). Shelf Life: 12 months from date of shipment


MCI® POWR 100 combines three functionalities in one product. First, the silane component of MCI® POWR 100 provides water repellency by chemically reacting with the cementitious substrate under proper application, decreasing the ingress of aggressive materials. Second, the oleophobic additive modifies the concrete surface to increase resistance to oil and food stains. Third, the MCI® component penetrates deep into the substrate, forming a protective, molecular barrier on embedded reinforcement to reduce the rate of corrosion at the rebar surface.


  • Commercial buildings
  • Parking garages
  • Bridges
  • Industrial or any other floors exposed to oils, greases, or water (e.g., automotive service centers and commercial kitchens)


  • Resists staining caused by food and oily substances
  • Forms a monomolecular corrosion inhibiting layer on embedded metals, inhibiting the electrochemical corrosion reaction between the metal and corrosive materials inside the concrete
  • Treated substrates are hydrophobic and resist the intrusion of chlorides and carbonation
  • Does not affect the color, gloss, or other visual aesthetics of treated concrete
  • Treated surfaces remain fully breathable and maintain their natural moisture vapor transmission
  • Extends the service life of treated structures
