I had a pub/restaurant to do this morning in and out. It's nearly all leaded. I normally WFP the outsides and do the insides trad whilst clearing up the odd leakage.
Today I had to do in and out trad and it took ages. I left the external upper floor. It's not so critical upstairs anyway. So I have taken longer, done less work, and have to knock a bit off the price this time. Ouch !!. At least I got something done though.
It was -5 when I first got there so as I was doing it all trad, I wimped out and started on the insides

.
It had warmed up to -2 by the time I went outside.
If it had been possible to do the job later in the day, I could have got away with WFP. However, due to the opening hours, I had to be away by 11 (10 if I don't do it on a Sunday) so I had to improvise this time.
