I have an ‘emergency’ clean tomorrow. A lady asked if I can clean at least half a tennis court that hasn’t been used in years. With the COVID thing going on, people are out of work and doing other ‘physical distance’ work, so a girl is borrowing this court to teach lessons.
Long story short, I have to use the equipment I currently have, no time to get nozzles and such. Currently have the usual jrod with low/high pressure fans, and the 2503’s on the surface cleaner which I will not be using.
I don’t have a 12v, do have xjet and downstream.
Advice?
Oh, and I picked up a floor squeegee after reading a few threads. Probably take the leaf blower as well.

I won’t link them all but I’ve read a lot on here about cleaning them. I just saw 5 threads with them. One from 2019. But I figure you’re under the gun and pressed for time.
Most just xjet straight sh with no proportioner in it. Let it sit, then low pressure rinse.

Yeah, spur of the moment thing, lots of that going on. If I had time I’d get a couple 3504’s or something for the SC.

You have everything you need to soft wash it, that’s generally the best way of doing them anyway. If using an x jet, worst case scenario you might have to hit it twice, who cares, rinsing is easy money. I would do the whole tennis court if it was me.

You can go high SH with equipment you have, let dwell and ball valve the rinse. Pump sprayer with high SH, some go above 10%, dwell and rinse. Especially if it’s a maintained court, doesn’t sound like this one is. I have a bid on one now, just going to use 12v and apply SH and rinse with warm water. You could just walk away if you can’t get the results you want or the customer needs.
Here’s the before/after.
I started with the xjet pretreat and attempted to use the ball valve for rinse, not a chance. This stuff was like concrete, especially under the trees. It even had lichen growing in spots.
Tried ‘high’ pressure fan on jrod, it worked with no damage but I wasn’t about to wand the whole darn thing.
This is where I’ll get flak, but my last resort was to throttle down my machine to about 2/3 and use the surface cleaner. That finally did the trick, no swirl or damage.
Tomorrow I’m getting a 19” Ultra and thinking some 2504’s might lower pressure enough. I’m still a little fuzzy on the nozzle calculator but I believe it should work.
Oh, and thankfully I remembered to bring my leafblower, lots of tree junk. A floor squeegee is a must!

Looks good man! Thanks for the update.

Thanks guys! Couldn’t do it without everyone’s help on here.
Now I’m embarrassed to ask, but if I wanted to get 1500psi out of each nozzle on my surface cleaner, the bar divides input PSI by two, correct?
I have a 5.5/3500 so to achieve 1500psi at each nozzle I’m looking at 4.5 orifice?
Oh time…so far about 4 hours, I still have to go back and do the sides and back on the last half. She has a ‘girl’ as she calls her that is out of work and is giving tennis lessons for now, so they are thrilled to get the court back in shape.
This is with a 16” Ultra mind you, took a lot longer than if I had a bigger setup.
I have used A strong mix of SH before, and over sized nozzles on my whisper wash… No issues, no lines, no color or texture loss
Looks good to me!

Thanks!
Hey, should I spring for the Classic or the 19” Ultra?
Great job! Looks great, no damage, awesome. That did look pretty bad, definitely no maintenance cleaning for sure. That was neglected for some time. Great job though working with what you had.

I can’t speak for the Ultra, but based on the pictures alone… I‘d go with the Classic, looks better built IMO
I love my 19” classic extreme, built like a tank.

Swivels are the same part number so will more or less perform the same, the classic will be more robust long term.
Haha sorry the sideways pictures made my head hurt
They are the same swivel, I got the classic extreme because it has an aluminum deck and seems to hold up better and I don’t need weights on top to keep it down.
