How to remove Cement from Mosaic Flooring

I am renovating my house. Now the problem is the labor has spilled all the liquid cement on my mosaic flooring....Please help...My mother is very angry and give me a regular dose of dant dapat due to this. :P

I have searched on Yahoo Answers...and there someone stated that sulphamic acid is the solution. Where to get it in Karachi. Urgent Help required.

Thanks in advance.

Really i like your post and there are many way to remove the flooring. You can share the lovely information about it and it is very useful information for everyone.

Scrub the hell out of it with oil-gasoline mixture.
