Remove Swirls from Painted Surface

What happens here

To remove swirls from a painted surface, attach an Ekasand Plus 10mm very fine closed-cell sponge to your sander. Gently sand the area with the swirls. The closed-cell sponge is effective at removing these marks and restoring a smooth finish to painted surfaces. It's important to be mindful that aggressive sanding can expose the bare wood underneath the paint. If this happens, the exposed areas will need to be primed before applying any further topcoats to ensure a consistent finish.

Goal: Eliminate swirls from a painted surface using an Ekasand Plus 10mm very fine closed-cell sponge on a sander, noting that any exposed bare wood will require priming.
