What should I charge for this roof? And how hot of a mix do you guys recommend.
5600 sq ft concrete roof, south Florida.
Very dirty.
How much per sq foot? It’s one story but very wide, almost no slope.
Not sure why I can’t post a picture on this.

Has anyone encounter a hairy paint like this before? It’s literally strands. I’ve been using Trigger Man Grafitti Remover, which has worked just dandy for the “normal” paint on the wall, but this stuff is bizarre. It’s finally started to fray, and I’ve been able to slowly take off layers of it, but I don’t know what on earth it is. I did test patches of Zep Purple Degreaser and Ecolab Citrus Degreaser, but those didn‘t make a difference.

Extra pics to show how the red and blue paint have come off (mostly) fine:

Hey guys, I have my excell 2800 psi power washer with my gx200. The pump is starting to act up after running it hard.

I spoke to CAT and I'm fairly sold on rebuilding the existing pump now being, it sounds like it's a bad check valve, I'm also going to replace the pressure adjustment stack, and add a pressure gauge on the middle pump port.

The tech explained that the pump puts out 2.9gpm and the pump is rated at 2,500psi, but Excell says it's rated at 2,800 psi. Cat said that the pump psi pressure is more about nozzle size then the angle of the tip.

I'm currently running an 18" DeWalt Surface cleaner with smaller nozzles that's the only major attachment I have.

The major reason why I'm split is the power washer is older, but I was thinking that maybe the 4DNX27GSI would give me a better balance being it's a true 3,000psi but at 2.7gpm. I think the main thing that I'm trying to figure out is is the older 3dx pump putting out 2800 PSI at 2.9 gallon per minute. Is it worth it to switch it out for a pump that's 3,000 PSI at 2.7 gallon per minute. And like I said, the only thing I have is the surface cleaner that seems to be the major appliance I use and I know with those water flow is more important than pressure.

What do you guys think?

Just need something that can wash cars, clean concrete and stucco. Purely home use.

Is there a goto pick for something like this?

Is gas mandatory or will a plug in unit suffice?

Do lmk

Thanks!

This is my first new construction cleanup job that I need to quote, and I’d appreciate some advice from guys who have experience with these.
The job includes:

1,000 sq ft metal-sided building that needs washed
Concrete splatter on some of the metal siding

2,600 sq ft of concrete flatwork

600 linear feet of curbs

5,000–7,000 sq ft of asphalt drive-through that needs rinsed after paving

Water is available on-site. The contractor wants everything itemized separately on the quote.
What would you guys charge for each service? I’m in Indiana if that helps.

Also, what’s the best way to safely remove concrete splatter from painted metal siding? Any tips for cleaning new construction concrete

I primarily do window cleaning, but i'm hoping someday to pay a lad to continue my round as I do gutter jobs and pressure washing.
Because of this, I bought a loncin g420 recently. I have had a little experience with the first lad who taught me how to do windows gutters and pressure washing. I do need to buy a surface cleaner and a lot getter lance, as the turbo lance I got thrown in isn't the best, but it works.

I used a 3% hypo mix, followed by a 4.5% but there are still a lot of black algae spots.

This was just my parents patio, good place to test if anything was up with the pressure washer.

Currently operating with a 16ft foldable ladder, and for the most part, I’ve been able to do plenty of jobs with that, but every once in a while, I’ve come across a house that I had to do gymnastics to get to the top gutter.

I’m in the market for a ladder, and I just want some help deciding if I could just get a 28ft ladder or would I just end up having to buy a 32ft or 40ft soon after.

What size ladders do you guys have?

What’s everyone’s preferred method? Used boosters, 12v, and air.

Air is the most reliable and have it on a truck but looking for something similar to a booster for another truck for larger jobs and has the ability to rinse. Seems like the new p40’s have improved a lot but wanting to get some feedback.

How would we approach cleaning this exterior? It has dark horizontal siding, dark window trim, and copper eavestroughs.

Would you use detergent only? How would you apply it, how long would you let it dwell, and what precautions would you take around the copper and dark finish?

I currently have two guns- a gun with a long lance (threaded) for edging, etc and a short gun with a quick connect end that I use for everything else. My long gun has just given up on me (leaks when off trigger- confirmed to not be an o-ring issue). I would like to use the lance extension with my short gun so I don’t have to carry two guns. Rather, just one gun and all the attachments/nozzles that I need. This seems like the simplest solution but that begs the question: why do I not see everyone doing this?

Whats better? Using the short gun (suttner st-2305) for everything or keeping two designated guns?

Will you post treat these poop deck floor? I will be pre treating before running surface cleaner

1. Get a Pressure washer with a 'Built-in' Pressure Regulator/Unloader, Hook it up, run it, walk away with it still running for 5 minutes, and Done. ALL the seals are Cooked. 10 minutes.. oil leaks out. 15 minutes.. it goes 'Thunk'

2. Plumb the above system to 'suck' water from a tank.. You'll have trouble getting it to Prime, the it gets hot, you get to your second job, and No Go.. it won't Prime itself, because the valves are Too Small to 'Suction-Feed'.. and..

3. nobody told you to take the Thermal Relief Valve off, to keep it from Sucking Air, and you fry all the seals in 5 minutes trying to get it to prime itself.

4. You buy a "Kit" to assemble yourself with No understanding of 'How Pumps Fail', and you fail to prime it, and run the Bypass to the Buffer Tank.

5. You failed to get a Pressure Gauge with Adjustment instructions/ you don't read them anyway.

6. You ask another contractor to Guess at what you should do Next.. installing His 'Perpetuating Mistakes'.

SOLUTION- Find a technically inclined Service Department guy that is willing to 'Explain' to you How Pumps Fail..

And buy a V-BELT Driven pump system with Big Bypass line, Big Feed Line, Pressure Gauge, Adjustment instructions, and a Supplier that Cares about Reliability, so you get a Chance to be a Reliable Supplier to YOUR customers.

I took care of this stucco building. I downstreamed 2% then I sprayed with around 4-5%. I am still getting a staining after removing the growth.

Is this able to come off or is it just a permanent staining?

Disclaimer: this might be too much info but my last post was taken down so I’m just being thorough.
Short and sweet info:
10x10 concrete pad with 8-10” trim , acrylic paint and sharpie removal. I’ve put in

I washed a house and got a call back the next day the daughter got ahold of some acrylic paint and sharpie and started an art project on the back patio I just cleaned. I’m newer and get my clients by word of mouth so I surface cleaned the back patio, sidewalk, and driveway for free already. I haven’t been called for paint removal before but I love doing research and learning new things. I set expectations and warned the chemicals I’m using could cause damage before I started. I tried for about 3 hours on and off scrubbing and using some of my normal pressure washing & cleaning chems bc they have small children and are very health/safety conscious nothing worked. So I called them back out and let them know I’m breaking out some heavier chems and the sealant on the trim is probably going to get messed up, they said they would get it re sealed which I’m also hoping to get that job. Anyways I tried a few chemicals but didn’t want to overdo it so I went light and used a lot of scrubbing with a wire brush and elbow grease. It was working but I was losing daylight so I busted out this $30 wire drill brush I didn’t want to open cause I was going to return it. I would say I got 99% of it off it was a giant pain in the butt but I have to go back when I have light to get the rest. The pictures don’t show a lot of bleed on the concrete from them trying to clean with soap and water after it was already too late. I also haven’t got to the table yet because I don’t know what to use to get it off without stripping the manufacturers paint also. I did a test spot underneath with some chems that didn’t damage. but I didn’t get around to putting it on the actual paint yet because when I warned him in my mess that pain up, he said don’t worry about it. I would really like to be able to get that for them, though. They both own small businesses. and have a lot of connections, so I’m trying to impress. Any advice from experience from anybody?

Pressure washed my driveway with an electric pw I got off of TikTok shop (😂) and some bleach. The bottom of the driveway is before obviously. I didn’t have a surface cleaner or anything and got it done with just the green tip in about 4 hours, I feel pretty proud of myself. Picking up a 4gpm washer and a surface cleaner from harbor freight next week as this has motivated me to go all in.

Every year I surface clean my front tile patio to get the dirt off, however, I can never get these water/red dirt stains out. The tiles also always have a slightly hazy look to them.

What is the best chemical/method to get rid of these?

I’ve included pics of the pressure washer, the floors and the cleaning stuff I found. My stepdad was the building maintenance man, but he passed away, so I’m trying g to make use of his equipment. I’d really love to clean the garage up, but def don’t wanna mess up the concrete.

I’ve read that I should I rent an attachment for the washer that spins on the floors so as not to put the cement. Is that what you suggest?

I was recently visiting a friend and he had rented a pressure washer to do some house work but was too busy to use it himself. I helped him out by pressure washing his porch. I was hooked - my ADHD brain loved seeing the immediate reward of what I was doing. Blasting away the dirt became some kind of game. So then I did his steps. And then his pathway. And then I dragged some small carpets out of the house and washed them. I was literally looking for more stuff to wash. I was so absorbed in it that I forgot to eat lunch.

I began thinking to myself - would I enjoy this as a job? Could I do this full time, if I seemed to enjoy it so much? Could this be a good fit?

So my question to you in the business is: is thinking it’s fun to pressure wash things mean that you’ll like doing it as a job? Do you enjoy it, in the kind of way I described above? Or does the “game of blasting dirt away” loose its appeal quickly? Are there headaches as a business owner that make doing it way less fun, and in some cases not worth it?

As the title says outside of a fancy/expensive truck mounted system what do you use ? X-jet, battery sprayer, pump up sprayer etc. I use a pump up sprayer and find it’s great for control but it’s very slow and doesn’t put out a lot of product which results in it drying up fast.

20+ years of grime on the sidewalk. Not sure about the house

I sprayed this exterior porch ceiling down with low pressure water. It looks like it activated (idk man) the varnish maybe? Wiping it with a rag did nothing and higher pressure just took off the stain. And by low pressure I mean like hose

I just got 2 kits from the surface maxx website for $18 each (it was $80 at lowes). I realized I bought the 3.5-4gpm kit and the 2-3gpm kit wasn't even available. I found some other 2-3gpm kits elsewhere and they all have the same numbers on the tips. Will this work for my 2.3gpm machine?

I restore pavers and occasionally people ask me to do their siding. I've been doing research on it for a while so I could one day add soft wash to my services and finally bought the j rod kit to mess around with. I used a pump sprayer with 2.5% sh on my siding...hosed it off and it's never been cleaner lol.

I'm not against getting a bigger machine, I bet I could clean pavers faster too. 4000 psi won't damage pavers with a turbo nozzle, would it?
