How do I get a neat edge and keep overspray to a minimum?

Use quality masking tape on clean, dry surfaces. Seal tape edges with a light first pass. Spray light, even coats and aim the fan just off the masked edge. Remove tape once the final coat has tacked off. Adjust the vari-nozzle to suit the area and reduce overspray.

Can I mix aerosols and tins on the same project?

Yes. Use the same colour/code and system, and test first. Blend on natural breaks such as trims or panel edges to hide texture differences. Keep gloss level consistent for a uniform finish.

Help! I’m seeing runs, orange peel or dry spray

Runs: too much paint or too close—allow to cure, de-nib/flat and recoat lightly. Orange peel: heavy coats or poor conditions—use lighter passes and maintain distance. Dry spray: too far away or windy—move closer (around 15–25 cm) and control airflow.
