Is it just me or does anyone else not like doing these?

I was doing one earlier, concrete drive with block paved borders and divides in it.  The fsc just looks like it streaking whilst cleaning. Rinsed it, still looked streaky. Although when it dries it looks great.  I always turbo over concrete just to be sure.

Does anyone else get this?

 Think every time I see streaks whilst cleaning my heart skips a beat!

You might be moving/walking to quick with the FSC? if it looks streaky

hi jettaway
dampen area first to relax the mosses and alge's first   then walk foreward at a even pace (you will probably notice streaking)  then walk back wards in the same track and speed  you should then have a near perfect finnish    make shure you have enougth clearance between skirt and surface to allow flow to escape    this will allow spin speed to be constant    use correct nozzles for your power unit and jets for the surface you are washing      hope this helps

I had this on some slab flooring recently.

I was convinced that it hadn't been cleaned properly, dried perfect. I think it is the back edge of the FSC/turbo nozzle leaving a line in the wet surface.

It's how it looks dry mate, not wet

Shame its not like that for women huh..

Bang some hypo down after, it will bring it up uniformed.

[Jettaway]

There's some good suggestions in here, I will try them all. Think I could well have been walking too fast.

Nozzles: im 300psi @ 16lpm with 2025 Nozzles.

Just seems strange how it dries lovely yet looks stripey when done, I rinsed it so lines weren't from loose dirt deposited by fsc.

Thanks Rob, its reassuring knowing that its not just me going mad hahaha.

I did think that it needed hypo when it streaked, I nearly left the job to head to my lock up to get some. If it had dried streaky I would have done.

Lee, do you have any problems with streaking on them wet pours in your videos?

[Kenny83]

I have had it too, as Lee says hypo sorts it, I find it best to put the hypo down first on concrete to eliminate streaking, run through the venturi is enough dillution. I think it's caused by when the whirlaway over laps the previously cleaned area and so double cleans the that part leaving the lines
Hope that makes sense?
 

[Jettaway]

Cheers Lee, it sure does, I think your right with the overlapping..

Gonna hypo the next one and see any difference it makes

[Blast Away]

You can do mate but we use hypo anyway to further clean them because of the ingrained soiling in the pours.

[Matt Gibson]

Tarmac is the worst for streaks. Have to overlap so tightly so as not to leave lines. cant say ive dont much concrete.

[Jettaway]

Its the other way round for me here matt, I do more concrete than tarmac.

I've not had any problems with streaks on tarmac. Well, I had one tarmac job that streaked but I blamed that on the state of the tarmac. It was worn out and completely faded. It needed re painting really

Just pre wetting the concrete or the blocks first will make a vast difference even if you use Hypo first you should still pre wet so the Hypo works on the surface where you want it to work and not sinks straight in.  Try it.....
