As title says, I have an industrial unit(exterior) to quote, the cladding is corrugated coated metal with a grain kind of leather look.  The cladding is a kind of off-white colour and has some dark weathering marks where a previous sign hung.

My question is what will be the best process to clean this cladding and removing the dark markings?

Having never done this kind of job before, what do you think about this.

1),TFR applied with a sprayer,
2),then adjitate(sp?) with WFP
3),spray again
4), then pressure wash.

This is a decent sized job with some hights getting up to 28ft.

Any help/advice/ideas will be greatfully accepted.

Hello Simon

we have done several of these,

we use hot pressure washers, and cherry pickers.  there are a numbr of differing chemicals that can be used some of them being paste based and requiring high levels of labour to achieve a result.

you need to establish how old this cladding is, as some have uv protectors on them some dont, the discoluration being due to uv, tfr does not really tuch this type of issue.

depending on location and size of job, we would be more than happy to take a look, and prvide a test area, so that the client can decide what level of finish they are looking for.

please feel free to contact me if you wish to discuss this further.

Hi simon
  you are about right but when you first apply the tfr make sure you start at the bottom and work upwards as if you start at the top it can leave run marks that are very hard to remove, what we usually do is apply the chemical through a venturer and soap lance attached to pressure washer then agitate with a brush and finally rinse of with a pressure washer you will find you probably wont need really high pressure as the chemical and agitation has done most of the work, if you need any more advice feel free to give me a bell as we do lots of this kind of work.

I tend to use non caustic TFR but as above
