Removal of sandy composition

Hi all,

In the process of renovation of a small shop I have discovered that the building has very nice flooring so I intend to sand and polish the floors and coat with
(Estapol and tung Oil) perhaps unless we gain a better idea from the forum.

The problem I have is there was thin masonite laid all over the floors and was "glued" down to accomadate a carpet layer . I think this is some type of "sandy composition" type of "glue".
Do any of the members have a way or suggestion for the removal of this. It seems to chip away and leave a clean floor board. Any ideas welcome.

Regards Mike. :wink:
