How do you guys minimise fsc lines on a tennis court.
I did a test patch on a court last week, tried winding pressure down,not all the way but about 5/6 full turns on a 3000psi unloader. It cleaned the moss up no problem but still left a few lines. When dried it looked a lot better and customer was happy with test but i have warned about lines. The court was painted originally but the paint has worn away and is very patchy, tarmac underneath is very faded too so that doesnt help.
What else could I try to reduce lines, I have thought about winding pressure down a bit more, increasing fsc jet height, maybe 030 nozzles, walking slower?
Any ideas?

If they are overlap lines then better rinsing will help. If they are rings then change the angle of the nozzles to wider ones and this will allow you to walk the same speed. If you got up a size on the nozzles then you can maintain the flow but will decrease the pressure - same as you have done on the unloader but without the water going back to tank

There walking lines from path of fsc
So you think to try 40° nozzles and may also 40° with 030.
-
If they are overlap lines then go half a fsc on every pass so in effect its done twice. Old tarmac is always a pain to get right
-
Also you could try pre wetting the area to soften the muck up a little, maybe even put a diluted blanket of detergent down or hypo run through the venture (if you have one)
:)

I don't have one Lee but its good advice. You would need some hypo to clean a court tho. Might try the half over laps as Carl suggested.
Gonna raise nozzles a few mil higher too, hopefully that'll be the key :-)

Chris,
How we have done then in the past is, FSC to get the worst off, then a light hypo mix say 4:1 or 5:1 sprayed on allow to dwell, then fan lance or FSC off, then wet-vac.
As Carl said half over laps will also help with the FSC, maybe keep your walking speed down?

Thanks Roger,
Maybe I was too fast with my pace, so will try it walking slower in future, I did have a pace on as was using fsc to primarily remove moss as apposed to clean the surface.
Job turned out OK, was a few stripes but barely noticeable when dry. Customer was very pleased. I think at normal walking pace it would take an age to clean the whole lot. Plus rinsing takes an age on tarmac as it is.
But the job needs what the job needs :-)

Id just use a pressure washer with a turbo nozzle fitted to clean that ! Much much quicker.
