How to Use

Remove all loose dirt and debris from the area to be coated. If required, clean and thoroughly dry the area. Remove any previous surface coatings with a wire brush and / or abrasive paper.
2. Shake vigorously before use
Shake can vigorously before use. Apply from 15cm to 25cm in light coats. Do not flood. Apply lighter coats to avoid runs. Apply 2 or 3 light coats, allowing 15 minutes to dry in between coats.
3. Storage & Reuse
On completion of use, invert can and depress actuator for a few seconds to prevent nozzle blockage. This aerosol should be stored out of direct sunlight, in a cool well ventilated place.
