Jet washer swirls in my tarmac

Hi

i recently jet washed my driveway and it has left swirl marks could anybody tell me how I can remove these or will the disappear on there own ?

thank you in advance 

Looks like the jets are blocked or you have used a turbo nozzle and missed loads of dirt it won’t improve with time what pressure washer is it and what lance and nozzle set up are you using , could be you have used a pencil jet rather than a fan jet ?? 

Aye, one of the nozzles will be blocked with a bit of sand. I press a small piece of wire up it to clear it or buy a new one.

Doesn’t look like it’s been done with a flat surface cleaner ??? 

My guess is a very small domestic PW with a 10" fsc with one jet blocked and not enough pressure.

Are you using a karcher domestic or a flat surface cleaner with almost pencil jets as apposed to fan jets. 

Tarmac is deep porous substrate which holds dirt deep within it's structure and pressure washer with either the incorrect equipment or jetting can produce horrendous results

Looks like a karcher K4 with their dirt blaster tiny turbo nozzle

You need a more powerful pressure washer with higher flow and or a flat surface cleaner or a fan jet nozzle rather than a turbo or pencil jet , will be difficult to get good results with a small karcher, sorry ??

Aye, you would have been better hiring a professional one at the same price of the karcher.

Just buy some Tarmac paint and paint it..

With respect hire someone with a 21lpm machine with 20" flat surface cleaner. Being honest I think you'll struggle to remove that now unless it's sprayed with hypo first 

I refuse to clean tarmac even with 13 years experience with pressure washers 

I wouldn't refuse to clean tarmac a job is a job just manage the customers expectations...

I clean my tarmac drive every couple of years and it isn’t an easy job to remove all the silt , but if you don’t  it does look awful . 

Tarmac paint ?would be the best way to sort it out lesson lurnrd don't use a turbo nozzle on Tarmac ditch the k4 and get a petrol one for ?
