Two ways to handle a nasty flue: scrape dry or spray first, had a rough Tuesday in Fall River
Had a job Tuesday in Fall River on a 1920s colonial. Creosote was glazed and thick, worst I have seen in a while. One guy on my crew swears by scraping dry with poly brushes first, the other says spray with creosote remover and let it sit 20 minutes before touching it. We went dry, took 4 hours, and I still think spraying would have been faster. Which way do you all go when the glaze is stage 3?
Feel for you man, stage 3 glaze in an old colonial is a whole different beast. Had one like that last winter where the stuff was like black glass, dry scraping just polished it instead of removing it. We burned through two poly brush sets and half a day before admitting defeat. Spraying first would've softened that shell up and saved us hours, no doubt. Four hours dry on that mess sounds about right, and your arms probably feel it today. Sometimes the old school way just costs you time when the glaze is that far gone.
