I am giving a bid for a very large church in the neighborhood. They have expanded considerably adding on to the original building. The job will consist of full exterior cleaning and partial interior. Some of the windows on the inside and outside will be CCU. This will be my first time with ccu so I want to make sure I am fully prepared to do it right.
The main issues I am concerned about are
Overspray on the windows
Overspray on the frames
Gray stuff on the windows and frames indoors
-I don’t think the paint on the windows will be a problem – I plan on using a scraper (waiver of course).
-For the frames, someone suggested steel wool. I got a huge roll from WCR and have yet to use it and was wondering if there are any issues concerning using it I should be aware of.
-My biggest concern is this gray stuff on the inside windows. I was able to use my fingernail and scrape little chunks of it off but it took some effort. I thought I might scrape it as well but I don’t know if there is chance that the residue will scratch the glass. I am not sure what the best way is to remove it from the frames either. What is the best way to remove this stuff?
I also planned on bidding the ccu portions 4X the normal cleaning cost. Does anybody think this is too much? My reasoning is 2X for the window scraping, 1X fior the frame and 1X for the cleaning. Someone else suggested 3X for the ccu parts
Are there any other issues I should be aware of? Any suggestions?
Thanks everyone !
I’d use a hogshair brush on the glass to apply your solution prior to scraping – it won’t trap debris.
Goof Off works well on frames for paint removal (prior to glass surface cleaning.)
I have, on occasion, carefully used a putty knife to knock-off large chunks of mud on frames, then used a white pad or light-duty sponge to grap the rest (separate bucket…)
I’d use bronze wool instead of steel because of rusting issues. The gray stuff looks like drywall mud and possibly plaster. On the frames drywall mud can be dealt w/ by using a white scrub pad. The plaster might need a little help on the frames. Maybe something like Titan Labs Cement Off. On the windows I completely agree w/ Larry - use a hoagshair brush. It will remove easily the drywall mud and should do well w/ any plaster on the windows. One caution w/ plaster - it has sand in it so be careful as it can become a source of scratching.
