If i use sh on the organics on this concrete and brick, i think there’ll be some stains from the oxydized window frames paint runoff that’s also in the brick, which products would be the best for that without needing high pressure ? Can softwashing clean all of this using sh then another product (cleansol bc?) or will i need to get up there with pressure ? I know there’s also efflorescence on there but it’s not part of the job.
@racer uses a different method than me, I use some weak acid and a brush, I think he sprays a stronger acid multiple times. He posted it on the forum somewhere.
Keep in mind that acids attack mortar, so dilution is not the same as neutralizing. A thorough rinsing for a diluted product should suffice. As with everything, do a test spot in an inconspicuous area.
Figures, your in Canada working, and I’m well south of you either freezing or raining. Getting agitated sitting in the house.
I’m just working on quotes, haven’t started washing yet, it snowed yesterday still. I’ll start next week hopefully !
I’m also getting agitated ! I’m literally pacing back and forth in the house. Lol
Well instead of pacing around, go over there and do a test with a pump up of SH (at least 6% mix) and spray under one of those lower windows. May take 2-3 applications with about 5-10 min dwell time each. Medium pressure, ie softwash nozzle should be plenty to rinse with. May need your shooter tip for the higher stuff. Once you’ve got that done spray frames with some wire wheel cleaner, or something like one restore, let sit a couple of min, may want to hit twice, couple of min apart with no rinse in between, ( don’t let dry on glass) and rinse with same medium pressure, about 500 psi, Should probably take 60-90 min to do that whole front section with the windows, assuming your 12v will shoot high enough.

When temperature isn’t above freezing i can’t use my equipment, i don’t want it to freeze. But i did go there yesterday with a spray bottle to show a test spot on the concrete.
Thanks for the tips @Racer
Today is warmer, i can start the season !
@Dirtyboy are you working yet?

Please don’t go there. We were supposed to have 2 days without rain or freezing weather and I woke up to rain and the radar is showing rain for 4 more hours. No wonder kentucky is under water if they are getting half of what we got. It’s the end of the winter so the general warming trend is there, we are only getting freezing temps 2 more times this week but every other day is calling for rain for the next week - week plus.
Sorry it’s hard to read your reply, the sun is shining too bright. I’ll get some sunglasses.
Lol
