cleaning concrete/upvc from windows
« on: March 16, 2008, 08:21:01 pm »
hello,

Can Someone Help ?????

I specialise in builders cleans and am usually last on a job for clean then sparkle etc, I went to a nice big job this weekend 15 units, and this company gives me alot of work, got there this weekend and the window frames and windows were covered in concrete and i was only there to get the site ready for the mastic man, I took 2 days trying to get this s*** off and eventually managed to pressure wash most of the frames with my washers, its 4000psi but the water pressure was very low (borrowed from a neighbours garden then ran about 50 metres via hoses.....

Has anyone got any ideas how to get this stuff off ? I am struggleing, some advice would be great of ideas....

Are my washers powerfull enough ?, is there a chemical I can get, please HELP !!!!!!!

4000psi is more than enough to do the job on upvc.
If you get at quite an acute angle to the upvc, then the mortar should just fly off (literally).
You can use brick acid, but be careful on the ocncentration as the upvc can be etched by the acid if it is too high.

Cheers
