I do a lot of commercial stuff and try to keep a fresh edge going. A few hours on each side. I have gone through several in one day, but that was sue to trash on the ledges that kept nicking my blades.

I usually get a day out of one rubber. That is if Im using that one sized channel for just about everything. When doing residential for example Ill use a 12inch for almost everything. Once I start leaving too much water behind I start to push down harder. if rubber was cheaper Id be changing twice a day.
Nothing like a fresh rubber. When I change a blade in the middle of a job I can feel the difference. TIME IS MONEY TOO. I think I can move faster with a fresh blade. The money earned on one pane of glass more than covers the cost of changeing my blade.
Sometimes you can run into rough edged frames that chew your rubber up. Usually they’re wood. Sometimes I run into frames caulked with a gooey substance that gets on the edge of my rubber and I have to change it frequently. Generally, one rubber a day is the norm.
Like most folks, I get about 7-8 hours out of a rubber, I use ettore. I use a bunch of different sizes so its easy to lose track of how many “hours” a particular rubber has on it. Basically, as soon as it starts to give me problems, streaky, more effort, having to change the angle, I flip it or change it out. As has already been mentioned, it is way worth it to not waste time with a rubber that needs to be replaced.
On residential I pretty much only use the squeegee on interiors because I mostly use WFP on exterior. For this reason my rubber last twice as long as it did before I got into WFP’ing.
Most of the ruff stuff that nicks the rubber is on the exterior so I can do 2 or 3 days of residential on a single rubber.
On commercial work I get 1 or 2 days with one rubber by using both sides.
I really don’t time it though. If the rubber is nicked or so dull that I have to apply unnecesarry pressure then it’s time to change the rubber.
I find this very interesting. I have been rolling 2 to 3 homes per day, since season start and I have yet to go through a 12 pack of Ettore rubber. I have been waiting for the rubber to fail but maybe my skills have gotten better. I just flipped my rubber the other day that is in my 12 inch that is used 90% of the time. I had that same rubber in since the 1st week of July. I find my helpers go through rubber fast. They press way too hard and I’m pretty sure that is what is killing the rubber. Unger rubber on the other hand, I’m lucky to get 1 week out if it.
wow im surprised at how often most of you change out your rubbers. im with juggernaut, i usually flip mine around at about 3 weeks then get about another week then toss it. unless nicked or leaving to much water ill switch earlier. and i change mine more frequently then my other two partners. we do primarily residential and use about 14" and 6" with ettore rubbers.
Commercial jobs (a day), I go till the ends start to show weare or leave streaks or lines because a nicked edge. I will flip over and use till completly worn out. Residential can usually go a little longer mostly because you are not so hard on the blade.
