Here we go with another.. Do you usually hire a sander, or use your own? Obviously the area of floor will answer this, but what is the cut off point between industrial hired sander, and your own. in your opinion.
I always hire a STR701 floor sander from a local company. I've got a variable speed polisher which I use on the slowest speed the get in areas the big one wont reach
I've never had to do the sanding, always get the developer to get the labourer to do it (it's cheaper for him that way). Any bits they miss in the corners I use a grinding cup on the variable grinder.
