Masonry cleaning advice
« on: April 17, 2016, 07:52:08 pm »
Hi all

Just getting into masonry cleaning, using a Karcher 120 bar pressure washer at the  moment, but need
something with a bit more power, can anyone recommend a machine and what psi/ bar should i be looking at.

many thanks

We use 250 bar @ 21 lpm, works well but need to figure out a better way of applying the acid as its eating the metal in my backpack.

Cheers Rob.

 Thats double what i am using .Is it worth getting a heated one so that i can use it to strip paint from stone work.

Depends if you have the call for it I suppose as a hotbox with all the other bits will probably be an extra £1500 ish, is it new build your doing?

This pic always sticks in my mind when anyone talks about brick cleaning using a pressure washer and what can go wrong getting the walls to wet.

Not the result to chap was hoping for to say the least  ;D

Not new builds..bog standard patios, walls, bathstone  ect. My set up is ok but the other day  i did a painted wall it took off most of the paint but there were some little bits left so thinking i need a better set up.
