Protectosil® 100

Protectosil® 100 is a clear, penetrating, breathable VOC compliant reactive penetrating sealer for use on concrete. The isobutylalkoxy functional silane allows for faster dry times and superior performance on high quality mix designs typical of new bridge decks. Creates a deep hydrophobic layer that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration. By combining ultra-low surface tension with a tailored rate of reaction, Protectosil® 100 is able to move through the moisture boundary layer that lines the pore structure of the substrate. This permits the development of uniform gradient permeation - a consistent level of protection throughout the entire depth of penetration — allowing for longer treatment life, especially on wearing surfaces.

Features & Benefits

Ready-to-Use Product Features
Product Benefits
  • Protectosil® 100 is a solvent-free, isobutylalkoxysilane. Meets VOC limits for California and other regions where limits for reactive penetrating sealers have to be less than 350 grams per liter. Protectosil® 100 penetrates deeper than traditional silane and siloxane solvent- or water-carried systems. This deeper penetration gives a long-lasting, resistance against water and chloride intrusion. Protectosil® 100’s breathable system greatly reduces the amount of water that enters a substrate, thus promoting a “drying out” of the substrate. Reduces the deteriorating effects of water, such as alkali silica reactivity. By incorporating Protectosil® 100 into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEED) credits for both new and existing construction projects.

Product Applications
  • For use on cast-in-place, precast, GFRC and high-strength concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and other waterborne contaminants. Alleviates deterioration of concrete due to alkali-silica reactivity. For use on bridge decks where fast drying is needed to minimize lane closures. For treating heavy-traffic wearing surfaces or areas that receive high salt concentrations (piers, coastal buildings), to provide a high- performance, long-lasting chloride screen.

Technical Details & Test Data

Limitation and Installation
  • Limitations - Not intended for below-grade waterproofing. Should not be applied if the surface temperature is below 20°F (-7°C) or above 110°F (43°C), if rain is expected within 4 hours following application, or if high winds or other conditions prevent proper application. If rain has preceded the application, the surface should be allowed to dry for at least 24 hours.
  • Installation - Generally, concrete must be allowed to cure for a minimum of 28 days, however there are instances which the cure time can be shortened. Please consult your local Protectosil® rep for the criteria needed to apply sealer before the 28 day cure time. Concrete repair and replacement must be completed prior to application of Protectosil® 100. Patching materials, caulking, sealing materials and traffic paint must be fully cured before applying Protectosil® 100.
  • All surfaces must be cleaned to remove all traces of dirt, dust, efflorescence, mold, salt, grease, oil, asphalt, laitance, curing compounds, paint, coatings and other foreign materials. Acceptable surface cleaning methods include shotblasting, sandblasting, waterblasting and using chemical cleaners.
  • Check with your Protectosil® representative to verify that surface preparation is adequate. Protectosil® 100 should be applied using low-pressure (15 to 25 psi) pumping equipment with a wet fan type spray nozzle. Alternate methods include using a spray bar or apparatus equiped with multiple nozzle tips which will apply a uniform coat across the concrete surface. Power rollers with a 1” nap or brushes are permitted, however using these will result in additional labor and costs. Do not alter or dilute the material. Do not apply to a wet or damp substrate. A test patch should be applied to the substrate by a Protectosil® representative to verify coverage rate and application conditions.
  • On vertical surfaces, apply the Protectosil® 100 in a flooding application from the bottom up, so the material runs down 6 to 8 inches below the spray pattern. Coverage rates on horizontal concrete surfaces are between 100 and 300 square feet per gallon. Your Protectosil® representative can give exact coverage rates for your particular project.
  • Precautions: Protectosil® 100 is a combustible liquid and should be kept away from heat, sparks, open flame and other sources of ignition. Protectosil® 100 containers should be kept closed when not in use and should be stored at temperatures between 0°F and 12°F (-18°C and 50°C), away from rain and standing water. When working in an enclosed area, an air respirator should be used.
