Hi, If I’ve read the above correctly, could it be to do with the original tradespeople’s quote, and, as Mr JT says, whether the OC has specified. Or simply that the OC is aware of varnishing as a different task compared with painting, the special materials etc, as Sir Humphrey says, and perhaps need a painter, or painters, experienced in one, or both types of applications and they intend to do that job at some other stage?
