i am in a new house and the person before me put slate tiles down in the kitchen which i am about to remove!! sounds easy huh? but he has put the cement straight onto the floor surface without any cement-board or even some thin ply-wood. Taking the tiles off is easy but i cannot remove the cement s it is solid. the floor is normal heavy particle board but it cant take much punishment! at the moment i have tried a wide chisel but its hard work!!!!!! Any ideas please
