Polyurea Primer for Concrete Substrates
Product Features
- Specifically designed for concrete and cementitious substrates to seal pores and improve surface density.
- Excellent penetration creates a strong bonding layer that significantly enhances adhesion of polyurea coatings.
- Fast curing allows higher application efficiency and shorter project turnaround time.
- Resistant to water, alkalis, and common chemical exposure, helping prevent moisture-related coating failures.
- Reinforces the substrate while reducing the risk of pinholes, blistering, and delamination.
- Fully compatible with spray polyurea, hand-applied polyurea, and polyurethane protection systems.
- Suitable for bridges, parking structures, industrial floors, water tanks, underground structures, and concrete protection projects.
