Ensure barbecue is cool before and during spraying. Lightly abrade the surface to remove loose paint and rust. Remove dirt and grease with Hammerite Brush Cleaner & Thinners. Then rinse with clean water and allow to dry. Ideal application temperature range is 8-25°C. Mask off the surrounding area to protect from overspray. To ensure optimum performance store the aerosol at room temperature for at least 2 hours prior to use .Prior to use shake the can vigorously until the agitator ball is heard and then for a further 3 minutes. To avoid runs and sags spray in light even strokes from a distance of about 15cm. Spray a light covering-coat. Apply a further 2-3 coats, allowing 15 minutes between each coat. After application leave the barbecue to dry overnight. Burn off all fumes before cooking food.
