F-13 all the way for us, pump-up sprayer and brush, makes cleaning gutter exteriors "Easy Peazy" We do not do gutter clean-outs (interiors) The one thing I do not like about using F-13 is on a hot day if we are not quick enough, paint will peel fast. I learned this the hard way, so now I use my ground guy to closely follow me on hot days making sure to rinse before drying.We have tried a few degreasers ( Dragon juice, EBC....) haven't found one that removes tiger stripping?
Truthfully I really do not care about the diploma,having you (Chris) as an educator is worth more than any piece of paper. Thanks again for offering all of your extremely valuable information! I believe you made roof cleaning what it is today (a valuable service for both contractors and homeowners) but having a few of the stickers would be nice just to show a little pride for the RCIA!
We have done a few monuments. We used: D/2 Biological Solution. (It is the same chemical used when washing the Washington Monument) It actually gets the monument cleaner as time passes, however its a little high on cost . For the extremely tough stains we also used our house wash mix and lightly brushed with a brush as well. All of this with absolutely no pressure and they came out incredible! Client had previously had cleaned by another contractor and they stated it wasn't anywhere as nice as we made it. Best to ask what chemicals the site permits. With monuments you have to be extremely gentle, so be patient and take your time.
Chris, Good morning , Hope all is well in the sunny Florida. I have yet to receive the "Certification Diploma Package" as previously mentioned. I had private message you all the information you requested.
Well we have a job scheduled for Tues Nov 29,2016 (Tomorrow) and it has rained the entire day....Is having this much rain going to effect my cleaning if the rain stops hours before the scheduled time ? The forecast for cleaning day is 10 mph winds with a high of 60 with NO rain for at least 24hrs.. Any/All responses to this post is gratefully appreciated !
We sprayed this detached garage roof on 10/11/2016 Our mix was 35% 12.5 SH/ 65%H2O As you can see it still looks terrible and the client is questioning the process used (these are the after 2 weeks pic's). We simply blew off all loose debris with gas blower then sprayed roof with 12v system and let dwell, no rinsing. We have had 2 good rains , unfortunately the temperature has declined but we have had days in low 60's. Is there anything we are able to do to increase our results ? I am confident we are needing to respray, but am questioning myself as to what process needs implemented ? The temperatures will be consistently 40-57 Any help with this unsightly situation is greatly appreciated !
I actually found a hypro pump. Real quick, I know this may be annoying, but will the hypro allow me to regulate the flow or is the air the ONLY way ? Sorry for all the stupid questions, I just am lost when it comes to creating mechanical equipment and just want to have the right system in place so when the time comes that we are 100% cleaning roofs we are successful without hesitation... Thanks for all of your professional knowledge !
