Can anyone recommend a non-chemical based patio cleaner. After ignoring the patio for many years, it took me 3 hours to clean the 75% of the lawn with the AVA pressure washer. It’s a beast.

The patio looks decent now. It will benefit from some soapy water. But, I can’t use chemicals or anything, which will kill my plants and grass;
because the waste water will end up on my lawn and plants.

It needs to be something, which won’t kill my grass and plants. Appreciate recommendations please. Thx

LMSC simonc I don’t remember. I remember measuring 2 or 3 bars! I was planning to bury PVC pipes. Does it work? How is it different to to MDPE

That’s the problem in the UK, our domestic pressure is so low. 3 bars will be ok, 2 might be too low but you need to check flow and importantly pressure whilst a tap is full open too.

I am just getting mine set up and cleaned and tested again and was reading up on the specs.

      Cleaned the Patio today all 700 sqft of it! takes me almost 4 hours to do with my pressure washer….a hated job but done now, and the patio looks better for it.

      Contact me

      The karcher patio cleaner is amazing, the enclosed one

        We didn’t bother cleaning it in 7.5 years. I am not joking. I was surprised it took me 3 hours to complete ¾ of the back lawn.

        Something to bear in mind with ‘prepared’ timber 3 mm is allowed for preparing (planing and thicknessing)

        If you are using T & G boarding ask for covering size.

        Composite decking buddy,

        And i did ask, twice infact😂

        Does it require spacers to allow for expansion ?

        Cuprajake Thx!

        Oops Jake!

        I had asked for a non-chemical patio cleaner.

        That’s a good deal.

          simonc Will measure and let you know.

          If it is 2, I would require multiple loops. Thx

              Thats just water pressure it comes as part of the k2 kit

              May of linked the wrong one

              These are the fixings, except mine are sq1 which is a square head

              LMSC flow is important too. If you maintain 2 bar when a tap is open, dynamic pressure, and flow is high then you would be ok.

                  simonc I measured the flow a few times. It averages about 1100 L/h. I haven’t measured the bar pressure yet. I will grab a cheaper tool from amazon. Hunter sprinklers suggest a minimum of 2.3 bar pressure and 1200 L/h to install 5 MP 2000 navigators.

                  Their 5 pack version is interesting!

                      LMSC that’s basically all the stuff I have but only one under ground so far and 2 waiting to go in.

                      That’s the optimal way to do a square lawn but there are others. Mine is rectangular so I’m just doing one in middle of each long side. The middle gets watered more than the rest but I’m ok with that. Better than the cost of running all the extra pipe and as I can only run one at a time all the extra control valves too.

                          simonc Thx. Mine is rectangular a half-polygon finish on one side. Spent some time developing this from barren lawn. I made the mistake of not top dressing to level out an uneven bumpy surface.

                          It is in a decent shape now, although it is not densely grown; as a result, a lot of moss has taken over since last season. We have now eliminated the moss, raked and aerated it. Will be top dressing and over seeding this week.

                          Plan to lay MDPE pipes just outside the edges, one each on all 4 corners,
                          one additional on 3 sides and nothing at the centre and on the semi-circle side.

                          The area is about 90 sq M.

                            Mines all over the shop 🤣
