I thought I would just post this update.  Having had a restful Easter weekend without doing any work in the studio, I am now ready to get on with the next job...damp proof sealing the walls.  I'll try and get some of this done during the evenings the rest of this week and more at the weekend.  Though this will probably go into next week because it requires 3 coats and 18 hours between coats.  Anyway, more soon.
