Streaks on Stucco, thoughts?

SH should get this off? What do you guys think? Its stucco.

What were the results from your test spot?

First time I’ve heard of that, what a great idea! I’m a newbie to soft washing so I’m still learning these handy tips and practices. I’ll make sure to do a test patch for next time, as now if she accepts my quote I run the risk of getting to the job and not being able to remove it.

@wap2dem SH will work, I would suggest you start at 3% and see how you go, let it dwell and reapply if you see it drying up keep it wet while it’s working, if it doesn’t come off repeat first step and rinse again thoroughly.

Thanks dude, I may have to get an X jet or backpack spray it off a ladder in that case as my downstream will spit it out around 1%

@wap2dem look into a cheap 12v pump if budget allows, very versatile and you can spray whatever SH percentage you want.

I was going to say pretty much the same thing as @MuscleMyHustle. Start at 3% and hit it a few times. It might take a little stronger mix but you can always adjust if need be. Don’t forget to watch any landscaping when spraying a strong mix. I would pre-wet the windows and shutters with water before applying mix. You want to hit any landscaping with clean water too and rinse immediately.

I second throwing together a 12v. An x-jet will work but 12v are a lot easier and super useful.

There’s a possibility that there will be a slight shadow left behind. Set those expectations in the beginning. Not much of one if any but it’s easier to let them know now then explain later.

Please dont ever use a backpack sprayer with any chemical used in this industry. Pump up sprayers are fine. Dont forget your PPE

I bought a backpack sprayer from My4Sons a local company here in town. They sell it on amazon. While it is backpack style (don’t use it that way) it is also able to be either set on the ground or used with an optional cart. It comes with a 15’ extension hose (high quality polybraid) so you can use it away from riding on your back. I also got the optional 11’ telescoping spray wand to go with it (before I got my 12v setup) which is nice because it also shoots about 20-30’ from the end of that. You can reach the third floor with it easy it just takes a little time. It’s battery powered too which is great. It’s great for very delicate application as there is a variable pressure knob to turn the spray power up or down. For a startup it’s an economical way to get smaller things done. I got mine without the cart for under $200. There are lots of YouTube videos from both the company itself and user reviews.

I looked over that unit pretty heavily, looks legit. Me or my helpers would never tote it around on our backs either. But I do see benefits of it over a poly sprayer, We do alot of pre treating on our higher end stuff and need dwell time, a poly is a PITA for multiple reasons. I just wish it had a flush out mode before the pump. Could fab one I suppose.

I have something similar but mine is a 15 gallon tank a 12v pump in a wagon 25 feet of 3/8 hose comes in super handy plus it rolls easy. And much cheaper than the other plus you can flush it

You can make your own little pump to push around. I made one using the frame from a homeowner pressure washer, a 1 gpm pump, a 7 gallon container, and 50’ of 1/4" hose. You can use any size pump you want. I mainly made it for spraying chems when doing decks but I suppose you could use it for about anything. I only have about $50 in it because I only had to buy the pump, hose, 7 gallon jug, and some fittings.

I think I’m going to make one with 7 gallon jugs for 2 step rig

I remember you talking about maybe doing some construction equipment.

The good thing about our homemade setups is you can easily swap out the pump or other parts if they ever fail. I bet parts for any pump sprayer are pricey. I think that 1 gpm pump cost me $20 on Amazon. Plus, you could always throw a bigger pump on if need be for different situations.

How do you power it?

I use 20v batteries off of my Dewalt power tools. If I remember right one battery can run the pump for about an hour although I don’t usually need it for that long. I bet those little Razor scooter batteries would work pretty good too. They’re small and light. They should last longer than my 20v Dewalt batteries.
