A floor sander is really just a heavy duty piece of equipment that you can rent from a home hardware store. That being said if you need to find an operator for this floor sander, any construction worker (you could ask your local hardware store) should be able to use it.
Rent a large floor sander, use rough (36 or 48) sandpaper and wear a good mask -it will make lots of dust.
About $80 to rent a floor sander and polyurethane is about $25 a gallon. So depends on how big of an area
You rent a floor sander from somewhere like Home Depot. They sell different sanding pads to go with them. Get goggles and mask too, this makes a LOT of dust.
there are several different price ranges, but you can expect to pay anywhere from twenty five dollars an hour, into about fifty dollars per hour depending where you rent from.
Orbital would be enough for refinishing. Much less chance of damage to the floor also. Unless you have used one before or the floor needs leveling, a belt sander can ruin a floor very quickly.
Rent a floor sander from Home Depot and remove it all very quickly. -Be sure to wear mask and goggles, it makes a lot of dust you don't want to inhale
In order to get a floor sander one must have accurate and precise knowledge of the issue at hand and must have the expertise to solve the conundrum okay.
A sanding machine will give your floors a more even look prior to refinishing. Sanding by hand will take a very long time. You can always rent a sander.
You really need a floor sander to do a good job on a hardwood floor.Unless you've got a small area it's worth the money to go rent one.The amount of time and effort you save is worth the money.
If it's hard and there is a lot of it, it's easiest to rent an industrial floor sander. Home Depot rents these, as do many rental stores. Get one and save a lot of backache. -But wear a mask and goggles when you do it !
When choosing an orbital floor sander for home renovation projects, consider the power source (electric or battery-operated), the size and weight of the sander for ease of use, the type of sanding discs it uses, the dust collection system, and the overall durability and quality of the sander.
