Description

Protectosil BHN is a clear, penetrating, breathable VOC-compliant surface
treatment for use on concrete. The unique 100% silane treatment (no solvent) penetrates the substrate and chemically bonds with silica to forma permanent attachment of the water repellent molecule. Creates a deep hydrophobic layer
that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration. By combining low surface tension with a tailored rate of reaction, Protectosil BHN 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.

Uses

  • 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.

Installation

Concrete must be allowed to cure for a minimum of 28 days. Concrete repair and replacement must be completed prior to application of BHN. Patching materials, caulking, sealing materials and traffic paint must be fully cured before applying BHN. 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 shot blasting, sandblasting, water blasting and using chemical cleaners. Check with your Protectosil representative to verify that surface preparation is adequate.

Protectosil BHN should be applied using low-pressure (15 to 25 psi) pumping equipment with a wet fan type spray nozzle. Alternate methods include using either a power roller with a 1” nap or a brush. 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.
