    Key Benefits

    • Rapid increase of internal strength.
    • Excellent bonding on most building materials.
    • Solvent and isocyanate free.
    • Extremely strong.
    • Permanently elastic.
    • Does not cause any corrosion in metal joints.
    • For interior and exterior use.
    • UV and weather-resistant.
    • Suitable for use with natural stone.
    • Suitable for rooms with high humidity.
    • Paintable with most water and solvent based paints. Can be painted wet on wet. After 48 hours, the surface must be cleaned first before it can be painted. Pre-testing is necessary. Alkyd paints require an extended drying time.
