Who would contemplate painting 250 square metres of theatre auditorium single-handed, with a 4in paintbrush?
Dave Williamson would. Moreover, having contemplated, he did it - which is why Birmingham's Crescent Theatre is greeting its early-season patrons in an impressive dark-toned flush of paint, painstakingly applied by Dave from seven five-litre cans.
A spray or a roller might have been quicker options, but Dave, who is one of the Crescent's three full-time employees, reckons that they would not have done the edges satisfactorily and rough-textured walls would have defeated all attempts to get into all the nooks and crannies.
"You just have to grab the brush and keep going in a swirly pattern to cover up all the old paint," he says. "I could have used a bigger brush, but bigger ones are unwieldy - and a 4in one is bad enough when you're going round and round to cover all the bits. You still have to leave it for a couple of hours until your shoulder gets back to normal."
Apart from the walls and skirting boards, the auditorium has five double doors and one single one - for which he did have some help - plus what he calls "the fiddly bits round the technicians' window."
He enjoyed the 100 hours he reckons it took him. He says, "You get left to your own devices and you don't keep looking to see what anybody else is doing."
And the theatre is understandably delighted at having saved something like £2,000 that it desperately needs, compared with the quotation of £3,500 that it was given by an outside contractor - although that did include the ceiling and the high-level soundproofing, which Dave did not tackle.
On the other hand, he did paint the blue wall at the back of the bar and two walls in the foyer.
And all this, despite the fact that he is colour-blind. "They have to choose the paint for me and say, 'Dave, it's that tin'."
He became a member at the Crescent 22 years ago and in the early 1990s was on stage in productions such as Pravda, The Tempest, Our Country's Good and The Wind in the Willows - all in the theatre's previous home, before its move to its prestigious £4 million canalside position in Brindleyplace.
But the three-month rehearsal period that was a feature of those days, plus a two-week run, prompted him to take up set construction instead. In his role as an unpaid member, he is now head of set construction and as a Crescent employee he is duty manager on alternate weeks alongside his responsibility for keeping the bar up to scratch - and doing the odd bit of painting.
By and large, he calls it fun with funny moments - such as when he was behind the bar, admiring a young woman customer while he poured her glass of cider and vaguely wondering why the bottoms of his trousers seemed to be getting wet. Then he realised that the bottom of the glass had sheared off.
Fortunately, half a pint of cider does not spread quite as far as 35 litres of paint.
