I just reached a verbal agreement with a local builder to begin doing his company’s ccu. I realize how good this work can be, and how important it is to be prepared. Besides the normal products/equipment that I would take to a storefront or home, what else do I need?
The following items are always in my vehicle: soap, scrubbers, squeegees, 6 inch scraper (with extra blades), free scraper from wcr :D, poles, 50 towels, and a few misc tools. I don’t carry any other chemicals with me.
I’ve been reading the ccu threads and keep seeing phosphuric acid for loosening debris…what else do I need that’s specific to ccu? I have my waiver all ready to go.
probabley need a heavy duty shop vac to remove all construction dust. Be very careful with the phosphuric acid if you haven’t use it before (for removal of motar on exterior glass) do not want to get it on the frames, you’ll ruin them.
I was introduced to a product last year called Cement Off. Its made by Titan Labs. It is by far the best stuff I have seen for concrete and mortar. You apply the product let it dwell and it basically turns the cement to the equivalent of a spit wad. It is very safe stuff and wont harm surface, it only attacks the cement agents. We used it on painted concrete block that had concrete splatter on and it was the trick and didnt harm the paint at all.
It is a must have for CCU. Chris should give Harv a call as they have it and can sell it to WCR.
steel wool is a good thing to have if you don’t already. I like to bring along trash bags for all the stickers and plastic. Also booties that fit your feet are good to have. I also like to use a drop towel or towel that I can put down on the floor or window sill. just to be extra carfull with a almost complete house.
All of the things mentioned are handy to have on a ccu. Another good product is magic eraser. After you scrape the silicon with your razor, take a damp magic eraser pad and clean up the smeared leftovers. It’s a lot faster than trying to scrape all of it
I use a spray bottle sometimes - especially when there is concrete or stuck on fines. I just spray the window & use my 6 " scraper first before even thinking about putting a T-bar on the debris. Just rinse your scraper in a seperate bucket. This is the fastest way for me when the window is loaded with gunk.
Mike, with the Cement Off, would you suggest using a hogs hair brush like Dan Fields uses to prevent too much pressure causing the mortar from scratching the glass? Or does the Cement Off dissolve the mortar enough to where this would not be a problem?
