Hi
One of our customers has anti grafitti coating on the bottom half of their hotel walls - as you can see from the picture it is quite badly stained.
The hotel owner reckons somebody tried bleach (I suspect Hypo)
Any ideas appreciated
I would normally walk away but it is for one of our biggest customers............

Is it sacrificial or otherwise?
-
Unless I'm seeing wrong, not seeing any bleach staining only staining from the air-ducts?
For me clean & re-anti graffiti coat the surface.
-
They tried bleach or Hypo to wash it off.

Heat, then re-coat the anti-graffiti coating.

I know it is a bleach we go through about 120 litres per month when were busy!
I think the customer probably means domestos or something similar as he had previously hired a local company to try and remove the black stain marks. :P

I think the idea is to save the anti grafitti coating as that is what my customer has applied to the hotels wall.

That's all well and good, but you may have to re-coat to get an even finish after cleaning.

I will go and take a look later this week and see whats what with it.

I worked on a massive graffiti problem on the back of a store at Hayes, this had a sacrificial coating on it, soon as we pressure washed it it blew off the brickwork.
I would take some washing up liquid and a bucket of water and see if it can be cleaned up with a brush and rinse off.
Roger is getting on but because I have youth I can see that it is on the LH side by the arched window. You can see that all of the coated area is streaked and I don't think it needs pressure washing but soft washing off.
If it is a sacrificial coating and you pressure wash it you will definitely need to re-coat.
Rob ;D

How old is the AG coating? Looks like the whole area that has been coated is discoloured. You can see the line where they applied it to. Could just be old/cheap stuff?
-
Reading through the e-mail
The hotel owner has stated that somebody came with a pressure washer and a bleach to try and shift the stains and it did not work.
My customer reckons they applied the Anti Grafitti coating in August 2012, I suspect that they coated over the stains :o
I will ask the questions tomorrow .....and when i visit the site.

Is it sacrificial?
No idea until I speak to somebody tomorrow

Rob I will give Fairy a go
Other than that I will blast it with HOT water from the hotbox and see what happens - if the AG coating comes off they can apply some more... ;D ;D ;D

Just finishing a 20 page Risk Assessment.
You get that Aquilla Hotbox out that should have been mine and knock the hell out of it ;D ;D ;D
Rob ;D

If it is a wax based sacrificial ,steam with a little pressure will remove it . If it is a permanent coating you will need a solvent. If it is a fluoropolymer you will damage the building in the attempt to remove it with the metheod you have suggested.
Gather as much information about the coating,ring the manufacture, start with gentlest method first.

Too many RAMS these days Rob.
We did an emergency bridge clean on Sunday morning in Balham - London - it took me longer to write the bloody RAMS than it took the lads to do the job - and they had to travel 1 hr each way to get there from our yard in CRAWLEY, WEST SUSSEX

Chris - my customer probably applied the coating - so I should be able to find out when I speak with them tomorrow, Thanks for the info - most appreciated.
As usual they just sent me an e-mail and gave little info other than a picture and a few words from the hotel manager...........

Check your public liabilty for cleaning bridges. None of the HISCOX policies cover it. Gleaming/polished etc

I really enjoy them now.
RAMS is one area where you can really stand out against the competition.
This new client, the one we spoke about has rejected two potential suppliers because of generic risk assessments.
They are a pain but I never compromise on them
Rob ;D

Only 20 pages Rob?

Old bloody cheek, if you can see the left hand side of the window then you are seeing a different photo then me? I still stick by the heat, gentle yes, then re-coat if needed.

So the AG coating was applied 4 years ago!
Still waiting for what was applied

Non Sacrificial Coating - Graffiti Magic

You now only have to determine if the marks are "on" the coating or "under " as you thought.
Bear in mind these coatings are designed to resist anything "sticking" to them if you have to reapply. The company will give you a spec for cleaning /preparing the surface for recoating. This will be the case if the marks are "under" the coating.

Grafitti magic are in Folkestone

Yes - just spoke with them.
The marks are definately "on" the coating or so i am told - i will nip out to Chingford on Thursday and see for myself!

Maybe a Noncaustic TFR or even a caustic cleaner such as SP10. Check with the manufacturer.

Armed with an array of things included all the free stuff the guy from The graffiti coating company kindly gave me when I visited his depot in West Hythe today.
