You can apply 2 coat of red oxide primer to the dry floor surface.That will serve your purpose.
Ask for 'red oxide primer' and get half ltr turpentine also. Loosen the primer by mixing turpentine a bit..Apply the second coat after 6 -8 hrs..
Red-oxide primer is actually used on metal surfaces to protect it from rusting.
