Description
POLASEAL VCI
Corrosion-Inhibiting Penetrating Siloxane Sealer for Reinforced Concrete Protection
POLASEAL VCI is a high-performance, corrosion-inhibiting penetrant sealer designed for the long-term protection and waterproofing of reinforced concrete structures. Combining vapor corrosion inhibition (VCI) chemistry with reactive siloxane technology, it delivers dual-action protection for both concrete substrates and embedded steel reinforcement.
Once applied, POLASEAL VCI penetrates deeply into the concrete matrix, where microparticulate inhibitors migrate toward embedded steel reinforcement. These inhibitors form a monomolecular protective layer that reduces ion transfer and actively suppresses corrosion. At the same time, the siloxane component creates a durable surface barrier that limits moisture and contaminant ingress, helping preserve structural integrity over time.
Designed for infrastructure and high-exposure environments, POLASEAL VCI helps extend the service life of concrete by addressing both moisture intrusion and internal steel corrosion.

POLASEAL VCI Application Guideline
Surface Preparation
- POLASEAL VCI is designed for application to untreated concrete surfaces. Any existing coatings that may inhibit penetration must be removed prior to application.
- Hard, non-porous coatings such as epoxy or polyurethane should be removed by sandblasting or wet abrasive blasting. Weathered or peeling paints may be adequately removed using high-pressure water jetting.
- All oils, treatments, rust stains, efflorescence, mildew, and other contaminants that could restrict penetration must be thoroughly cleaned from the surface.
- Complete all concrete repairs prior to the application of POLASEAL VCI. Restoration work should be finished in a manner that preserves the original appearance of the treated surface.
- A dry substrate is preferred to maximize penetration into the concrete.
Application
Apply POLASEAL VCI using low-pressure spray equipment, maintaining sufficient volume to fully saturate the substrate to the point of slight rundown or surface accumulation.
A single coat is typically sufficient for complete protection. However, irregular surfaces, projections, and shadowed areas may require a light second coat to ensure complete coverage.
Spray Application
Use HVLP spray equipment for spray applications.
Clean-Up
Clean tools and equipment immediately after use with water and detergent.
Limitations
- Store product between 38°F (3°C) and 95°F (35°C).
- Do not apply to frozen or saturated surfaces.
- Do not apply if precipitation is expected within 8 hours. Avoid spray application during strong wind conditions.
- Protect adjacent surfaces, including landscaping and shrubbery, from overspray. Overspray may damage raw copper or aluminum surfaces.
- Remove overspray from glass, metal, or vinyl surfaces within 4 hours using thinner or mineral spirits, followed by a glass cleaner.
