Description
POLASEAL VCI
Corrosion-Inhibiting Penetrating Sealer for Concrete
POLASEAL VCI is a high-performance, penetrating sealer engineered to protect, waterproof, and extend the life of concrete structures. It combines advanced vapor corrosion inhibitor (VCI) technology with reactive siloxane chemistry to deliver dual-action protection—shielding concrete from water intrusion while actively preventing corrosion of embedded steel reinforcement.
Formulated with microparticulate inhibitors, POLASEAL VCI penetrates deeply into the concrete matrix, where it forms a monomolecular protective layer on reinforcing steel. This barrier disrupts ion transfer, effectively halting the corrosion process. Protection is continuously sustained by unreacted inhibitors within the substrate, while a siloxane surface barrier prevents dilution and enhances long-term water resistance.
Key Benefits
- Reinforced Steel Corrosion Protection – Forms a protective molecular layer on rebar to inhibit corrosion and ion transfer.
- Deep Penetrating Waterproofing – Seals concrete from within to reduce water ingress and deterioration.
- Long-Term Structural Protection – Helps arrest concrete degradation caused by moisture and internal corrosion.
- Invisible Application – Does not alter the natural appearance of concrete surfaces.
- Freeze-Thaw & Chemical Resistance – Protects against spalling, acid rain, and environmental exposure.
- Chloride Ion Reduction – Helps limit chloride penetration and related reinforcement damage.
- UV & Biological Stability – Resistant to UV exposure, mildew, and microbiological growth.
- Low Odor, VOC Compliant – Safe, environmentally responsible application.
- Stain & Efflorescence Control – Helps reduce rust staining and efflorescence formation.
- Extended Service Life – Continuous inhibitor replenishment provides long-term protection.

Preparation and Application
Surface Preparation
POLASEAL VCI is designed for application to untreated concrete surfaces. Any coatings that impede penetration of the sealer into the surface will need to be removed. Hard, impenetrable coatings such as epoxy or polyurethane will need to be sand blasted or wet abrasive blasted. Weathered, peeling paints may be sufficiently removed by high pressure water jetting. All oils, treatments and contaminants that could restrict or prevent penetration of the sealer must be thoroughly removed. All repairs to the concrete should be completed prior to the application of the POLASEAL VCI. Cleaning to remove rust stains, efflorescence, mildew, etc., should be completed prior to application of POLASEAL VCI. All restoration work should be completed so that the surface that is to be protected will appear unchanged by the treatment with POLASEAL VCI. A dry surface is preferred to allow maximum penetration of sealer into the concrete.
Application
Apply POLASEAL VCI by low pressure spray, maintaining sufficient volume for saturation to the point of rundown or surface collection. Single coat coverage should be sufficient to provide complete protection; however, uneven surfaces, projections and shadows may cause areas to be missed. For this reason, a light second coat may be necessary to find and treat any of these hidden areas.
Spray Application
For spray applications, use HVLP spray equipment.
Clean up
Clean tools immediately after use with water and detergent.
Limitations
Store product between 38°F and 95°F. Do not apply to frozen or saturated surfaces. Do not apply if precipitation is forecast within 8 hours. Do not spray in strong wind conditions. Protect adjacent surfaces, including shrubbery, from overspray. Overspray may damage raw copper or aluminum surfaces. Remove any overspray from glass, metal or vinyl surfaces within 4 hours by wiping with thinner or mineral spirits, followed by wiping with glass cleaner.
Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
