Dusty clothes are evidence at a past moment. Sanding happened earlier and explains that evidence. The activity may have continued up to the reference point or stopped shortly before it.
The idea
Use had been + -ing for all subjects. Negatives use hadn't been; questions begin Had + subject + been...? The form foregrounds activity or duration before a past reference point, including repeated activity such as nightly rehearsals.
Examples
- I had been sanding the table, so my clothes were dusty.
- They had been walking for three hours when they found the bridge.
- Maya had been rehearsing every evening before the audition.
- Had the engine been making that noise before it stopped?
- We hadn't been waiting long when the lift arrived.
- I had known the guide for years before we travelled together.

Watch out
Do not replace had been with present-time have/has been when the reference point is past. The continuous does not assert that the task was completed. State verbs usually use the simple form: had known, not had been knowing. A past reference point must be understood from context.
Try it yourself
Choose the correct option. When the guide arrived, we ___ waiting for half an hour. (had been / has been)
Show answer or example answer
had been
Had been places the waiting before the guide's past arrival. Has been points to now and also fails to agree with we.
Choose the correct option. I had been ___ the table. (sanding / sanded)
Show answer or example answer
sanding
After had been, the continuous requires sanding. Sanded would not form this active continuous pattern.
Choose the correct option. I ___ the guide for years before we travelled together. (had known / had been knowing)
Show answer or example answer
had known
Know describes a state here, so use had known for the relationship continuing up to that past time.
