Hi all,

I would love to have some practical guidance at the beginning of this
DIY job.

I have just tried to break up the cement in the kitchen, I am using
about a 5 lb hammer and a flat cold chisel but don't seem to be making
much of an impact.

Is this normal and I just need to take it slow or is there something
else I should be doing.

I am digging about 8" away from the hairline crack, this is probably
the centre of where the pipes run parallel to wall, and just outside
the hollow sound of cement which must be over the pipes.
I would really appreciate feedback before I do damage!!!

Thanks,
