hi paul,
if you can get your hands on an airflo with a hoover attached, you will have a cracking finish, have a lookat my website and tell me if they are as bad as those, they would need sanding if they were,
anyway use the airflo with a scotch mesh, grit 60, then hoover the floor from the fine dust, then apply a good varnish maybe for a domestic put three coats of ronseal varnish you can get it at b&q, or hss, you will get a lovely finish,
if it just needs polishing use a good detergent maybe taski energy then let it dry then aply carefree emulsion polish about two coats should be ok
thanx and good luck jonny
let castle take the hassle
