@traciesites428 I have an xjet but it doesn't dose strong enough for this job.

@rickychatt works really well and is a fraction of the price of a dedicated dosing unit like a dosatron. It's also quicker and doesn't need expensive repair kits. I've used mine for years now and never let me down. Best investment I've made.

@DirtyDriveAway I'd say it is probably a good job it's the couple of hundred pounds for 20 quids worth of parts get me if it was 50 or 60 quid would be understandable

@rickychatt such as everything in life. There are a couple of components inside that are fairly unique to the product other wise you could knock one up with readily available parts. Yes it is a couple hundred pounds, but what you save in time more than makes up for it. Compared to manual spraying with a pump sprayer it's night and day. You can spray 100sqM with this in about 5 mins.

@bidders77 yeah I say between 1-1.5" anymore than that and the performance gets reduced. Also switch to 15degree nozzles. The std 25degree ones don't give enough punch to the floor.

@liamcrangle5977 no not really as its too damp in the UK to get the sand in right.

@dantec8854 if it uses a ball bearing and a spring, you could remove the spring and fit something solid inside, like a bolt, if possible. Some unloaders are different, and not all will be as easy to convert. All you need to do is figure a way to stop the plunger from moving.

@DirtyDriveAway so by removing the spring and adding the bolt the plunger will constantly pressed down on the ball to not build pressure right?

@dantec8854 yes, this will stop your internal unloader going into bypass. This will block off the bypass port when pressure is built up when releasing the trigger. The newly fitted external unloader will take over the bypass operation.

@@loraloren1972 350bar at 23litres a min.

@richardnichols2064 the GX390 motor is a good engine. Although the pump it's coupled with is all pressure and no water flow which is not the best way for cleaning performance. You can have all the pressure you want but unless you have decent water flow it will make cleaning hard. Is that pump gearbox? Personally I wohld junk the pump and fit something like a Interpump WS202 with an RS500 gearbox. You can then fit a K1 unloader like my video and it will transform your washer and cleaning experience. The WS202 is less pressure at 3000psi but it will give you 5.5gpm. I mean everything has a price point but you already have the engine. Upgrading the pump/gearbox will be the best option. 👍

@nathandarby1 just a gun or does it have the lance/nozzle attachment too. Can you define screaming? Do you mean like the washer sounded over stressed? Is the gun a generic or original part? Phill

@DirtyDriveAway hi bud, really appreciate the reply...it's a very basic Amazon job mate, and obvs comes with those generic nozzle attachments...as soon as I switch it on it sounds like it's going to blow up, although as soon as I ask for water from it, so depress the gun, the screaming stops...

@nathandarby1 hmm, in honesty generic nozzles aren't great. Unless you know the exact orifice size it maybe overpressurising the machine. The noise your hearing could be the machine labouring as the nozzle size is too small.

@@DirtyDriveAway interesting...ok bud, I appreciate trying to diagnose it in this manner is difficult regardless, appreciate ur time nevertheless. Nice one 👍

@ZorgR because sealers are expensive and customers don't want to pay for it. Also sealing is a bloody headache to do in the UK.

@radiocaf yeah it's a bit damp now to be undertaking it to be honest. I would buy the sand from Wickes as I've rarely found dry sand in B&Q or Homebase.

@DavidPeet-h4p it's not a weedkiller, it is salt based when dry but it won't actively keep weeds away. It can help with anything there at the time but it's not a long term solution. A decent weedkiller is best (glyphosate), just read the instructions and don't get it on anything you don't want to kill.

@@DirtyDriveAway thank you very much for the advice - much appreciated!

@TerryTibbs80 really depends on its size. I mean 145bar is quite underpowered. If it's not too big and you want to put the hours in then it will work. It won't come up quite aswell as a pro machine but it will do its best. The patio head cleaner won't do a lot on block pave especially at only 145 bar. Turbo nozzle is your best bet but it will take time.

@@DirtyDriveAway Cheers for getting back to me so soon and thanks for the advice pal

Hi again, would you advise using some sodium hypochlorite to assist in the clean?

@TerryTibbs80 yes, it will definitely boost the cleaner power of a small washer.

@JaspreetSidhu1 they all use 3/8"bsp fittings.

@@DirtyDriveAway So, I'm cross the pond and upon further investigation, it looks as if the outlet port on the pump head is 3/8 BSPP (British Standard Parallel Pipe) for which I can find an adapter for here in America, but as a follow up, can you share the specific type of hydraulic fitting style (e.g. 3/8 BSPP male to 3/8" Female JIC) or share a link to the particular swivel adapter you're using. Also, thank you for the quick response.

@JaspreetSidhu1 the swivel fitting will be a 3/8"bspp male to 3/8"bsp female. On the pump head itself it would be a female, so you can fit a 3/8"bspp equal nipple to convert it to a male. You then screw the swivel into the unloader and then the female attaches to the male nipple on the pump. Alternatively you can do it the other way around and have the equal nipple in the unloader and thr swivel in the pump head. Doesn't matter which way around you choose. America tends to use NPT threads which are similar to bsp but the thread pitch is different and therefore not interchangeable. I don't see JIC fittings on pressure washers.

@ssimba2785 yep, that's why it's no longer feasible to do it. The products are too damn expensive. Cheaper to have it cleaned properly every 2 years.

@eddiebarzoo hi, possibly. It's just the K5 is designed for 200bar and 11-16lpm. If the flow rate of your pump is less than unloaders working range then it may have problems cycling.

@@louisestevenson1038 you don't have to but I find it helps it to settle.

All block paved drives need re sanding after.

@CraigCatterson barrel/tank fed. Hose fed will usually be max around 10 litres per min, nowhere near enough for professional cleaning.

@@deankushin-lifecoach7778 welcome

@CraigCatterson possibly but it really depends on your karcher model. I think the smallest nozzle size you can buy is an 025. Most karchers are around 140-180bar at around 8-10 litres per min. You can buy them on ebay but you will need to make sure you buy the correct size otherwise it won't give you full pressure. If it's a domestic DIY karcher then they do their own version called a dirtblaster I think it is.

@richardjones3112 usually i use 3:1

@@DirtyDriveAway Thanks.

@SirBenJamin_ no it won't but a jet wash will. Resin pointing is soft as toffee and will blow out very easily.

@@OnPointExteriorCleaning hey, no worries. That K1 really makes a difference. Totally transforms the way the machine works.

@HandyChick I hate the "softwashing" term. It means I cant be bothered. Hypo reacts with the first thing it comes in contact with. If you've got lots of dirt and grime on the surface, it will only work on that and will have minimal effect on deep dirt and lichen. Pressure washing first gives the hypo the best chance of removing everything.

@evoluirsempre8164 I got mine from eBay. Try typing in turbo nozzle filter into Ebay. Alternatively, the Suttner ST33 is an excellent filter.

@YuriPeriotto low slip granules won't spray, personally I wouldn't be using anything like that as it will feel funny. No different then leaving sand scattered on it. I would put the customer off that idea. You'll need some xylene to clean the spray pack out after.

@chrisward3605 only if you make it high maintenance. Simply applying weedkiller every 6-8 weeks during spring and summer will help keep weeds at bay.

@littlekitty1468 sealing won't stop it getting dirty. Limestone is so porous that most sealers are impregnating sealers. Sealing limestone can help with deep rooted algae which is a common issue with this type of stone. Even after cleaning you can get left with a green staining on the stones. Most chemicals won't remove them as they are so deep in the stone. A long acting biocide like BAC50 can help but it's not gaurenteed.

@phsx2890 only if you have a steep driveway. If it's sanded properly and all the surface sand is blown off then you shouldn't loose any.

@brianherbert9608 I add a bleach safe surfactant into mine. Doesn't really do a great deal apart from show you where you've applied it. It cab help it stick on vertical surfaces but it's more to see coverage.

@jeanlaurensykes8232 hi, the problem with sealing is the dry time. Resiblock needs about 7 days after cleaning to dry out fully. I would normally sand and seal same day as that will ensure the sand is dry. You shouldn't need to weedkiller before sealing with resiblock providing you did a good enough job removing them when cleaning. If you did want to apply weedkiller then do it the following day after cleaning and allow to dry before sealing. The sealer will prevent moisture going through so will technically starve any weeds that happen to still be in the sub base anyway. Phill

@@enzorik you can if your machine is powerful enough. Unfortunately they struggle with the weeds.

@@swimgood3873 get a pump sprayer and some 360g/l glyphosate weedkiller such as gallup. Don't spray anywhere near plants or grass as it will kill them.

@@DirtyDriveAway nice 👌 You got any vids for re jointing patios , do you recommend Easy Joint? Thanks

@swimgood3873 no I don't do re jointing. Easy joint or any of those sweep in compounds are crap. They will all fail after a year or so and a jet wash will blown it out. Flowjoint or GFTK VDW is probably the best

@@DirtyDriveAway thanks

Nope, only drives with steep slopes tend to suffer from sand washout.

@@DirtyDriveAway how steep are we talking though ? sorry im fed up with weeds kinda got cowboys to do a drive & its shit

@graememcfee23 Any kind of incline where water will visibly run down. Weeds will always grow; it's the nature of block paving, unfortunately. Even freshly cleaned weeds will grow in a few weeks. A good weedkilling regime is the only way to stay on top of them or seal the driveway. Using a decent sealer will bind the sand, setting it hard. If you want the longest-lasting approach, then you need to use a Polyurethane sealer.

@@DirtyDriveAway how bout sharp sand & a cement mix ( sorry for being an arsehole lol 😀)

@graememcfee23 no, these driveways aren't designed to have cemented joints. Besides cement will make a hell of a mess if being swept in, sharp sand is usually wet and just won't sweep well. You will regret it if you try.

It can smell a bit like a swimming pool for a day or 2 but nothing too bad or unpleasant.

Poly sand sets hard but as a top up it doesn't last long. It tends to crack too easily, it's best used as full depth but you won't get that with a clean. It really needs to be used when laid so you get the full 50mm depth. When cleaning it's only around 5mm depth so doesn't actually bind much sand.
