A plasterer has just finished a chemical DPC at my house and
replastered. One of the walls was really bad but it's all done now.

This same wall, a few days later is still damp (he used Limelite
Renovation for both layers). I'm just wondering how long I should wait
until for this patch to dry out.

Could be damp for a while, at least a month, depending on the thickness of
the plaster and the weather etc. Did the guy not tell you how long to wait?
