    Key Features

    • Suitable for both interior and exterior applications (paint exterior repairs for weather protection).

    • Bonds well to most surfaces including masonry, concrete, timber, and primed metals.

    • Water and weather resistant for lasting repairs.

    • Fills cracks and holes in a single application, with minimal shrinkage.

    • Fast drying—ready for sanding and painting in just a few hours.

    • Pre-mixed and ready to use, with a spatula included for easy application.

    • Paintable with oil- or water-based paints for a seamless finish

    How to Use

    1. Make sure all surfaces are clean, dry, and free of debris.
    2. Press the filler firmly into the crack or hole with the flexible spatula provided on the lid and smooth off the surface; there is no need to overfill. Apply in 6mm layers for deeper cracks, allowing each coat to dry before applying the next.
    3. After the product has dried, lightly sand back any extra filler from the surface (2-3 hours for 2mm applications).
    4. Remove and loose particles before applying an undercoat and painting using water-based or oil-based paints.
