ok guys, got to put a quote in for some cleaning in a factory, they make pre fab concrete structures - stairs, landings etc.

They want some fire damage cleaned and some exterior cladding cleaned, thats not really a problem, although im not sure how im gonna get the cement lumps off the cladding.

Parts of the factory they want cleaned include the wash bay. Now this wash bay is caked with cement. whats the best approach to this? i know hydrochlorich will shift cement, but not this thick. Was thinking maybe a wetblast?
They also want some machinery cleaned, hoppers, cranes and buckets cleaned of the cement. Any idea on the best chem to use? Or should I just blast it with water?

Any ideas or tips? need to go and do a test so i wanna go with every approach possible.

Cheers,

Matt

I know a guy who does new build brick cleans and he says he knocks all the big pieces of cement off with a hammer 1st before cleaning with hydroclhoric

Yeah mate, i normally do that on new builds, but this cement is pretty thick...inches thick in some places. Im starting to think of trying a few different chems, and if that doesnt work, getting a sledge hammer and giving it a whack and trying to get the bulk of it off..

Might be your best option mate, or maybe a concrete floor scabbler?

[Matt Gibson]

Bit worried about using the acid after ive got the heavy stuff off though, cause it oxidises the metal..

A hilti with a flat plate will fly through it then use a scabbler or a floor grinder

Yeah the hilti looks like the best option for the thick stuff.

Problem is, most of the cement is on metal, stairwells(those metal mesh plant stairs) metal beams, metal walls etc.. so the scrabbler is out of the question without risking damage to the steel underneath. But in saying that, the metal underneath is gonna have to take some kind of hit regardless, with chems, or otherwise.

You will get the rest off the stairs with acid mate it wont have bonded that well once you get the snotters off
