Block paving

[Aquajetexteriorcleaning]

Cleaned a driveway today, took ages, every time I think I've finished I look down and some of the joints are full of dirt, it's like I kept chasing it moving it from one joint to another.

Now they want it sealed, will it be ok if some of the joints only have a few ml of sand on top of the dirt? Will the sealer just make the dirt hard as well? If so should be ok yes?

I cleaned it with a fsc and then went over bits with a turbo nozel.

Have you got any pics mate?

What litre machine you got should really get all dirt out and replace with fresh kds

The only problem I have had with sitting water/dirt in joints, is in places of bad drainage.

If you have a gutter sucker then hoover the mess up or brush it/power blast it to your nearest drainage area.

This is probably the one thing that gets on my t*ts with pressure washing, that and pea shingle boarders lol.

what machine do you have?? should sought any probs with a turbo nozzle??

 

[Aquajetexteriorcleaning]

21ltr

I think I shall get a screwdriver and scrap some of the dirt out and suck it up the hover before resanding. Then seal it.

What jets you got in the FSC? standard ones? if so get them changed, the standard jets won't shift the dirt in the block paving gaps, I have had this issue for ages now, I have only just replaced mine with better jets and did a patio today and it seemed MUCH better, can't report on block paving yet though.

Turbo nozzle on block paving is my advice unless these new jets work.

 

[Aquajetexteriorcleaning]

And maybe only use turbo nozel on block paving in future.

 

[Aquajetexteriorcleaning]

Mine is just the standard jets. Where did you get your ones from.

 

[Diwrnach]

Same litre machine as mine, you will need 15 / 035 jets.

Cheers bud

I have been reliably told that with these jets you should clean block paving much better, I hope its right as I have the biggest block paving job I have done in a few weeks, its probably 25-30 meters long and maybe 20 meters wide, with three block paved driveways joining it. If I have to turbo it all I will cry.

And your hands will be vibrating for days lol

Had the exact same problem this week. 20" with a 21ltr 3000 psi, got the correct size jets (can't remember size) once it had dried I noticed maybe 20 small bits I'd missed (biiig drive though) that's after I went over checking with turbo. Sappose it just can't be helped? Or maybe go down to an 18". I was running mine through 70metres of 3/8 hose though so I'll lose a bit of pressure

Most fsc come with (in fact I think all do) 30 degree jets, 15 is what I have in mine now.

I bought the 15 degree for mine, but for love or money I cannot get the old jets out to replace. Any tips on how to remove the old ones as they are STUCK rigid.

 

[Drive Revive]

I've not had any problems getting mine out but maybe wd40 or a little bit of heat

I had to use a plumbers gas torch to heat mine up when I replaced mine worst case if they are really stuck you can replace the whole bar or at least take it out to get a better angle on the nuts.

 

[Diwrnach]

Mine were tight as well, I just pushed harder lol.

But heat will usually do the trick, I have read sometimes they are put in with Loctite? heat will break that bond straight away.
