    • Brush or roller application
    • Instructions for Use - Thoroughly stir the paint to ensure it’s well mixed. Use a roller or brush to apply it to the affected area. If it’s only a small damp patch, paint at least 30cm around the area so the damp won’t creep elsewhere. The seal will be touch dry in only two hours.
