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.

The Basics of Refinishing Hardwood with a Floor Sander?

The thought of refinishing a hardware floor can be make a homeowner cringe, especially if multiple rooms needs to be done. A floor sander can make this job significantly less labor-intensive, allowing avid do-it-yourselfers to tackle the job and save some money. Sanding is the first step to the refinishing process and the purpose is the remove the existing varnish or lacquer from the wood. Wear and tear on a hardwood floor shows up as tiny scratches and scuffs that make the wood look dull and old. Refinishing can breath new life into the floor and make the room more attractive. Refinishing hardwood floors is an important project to finish before attempting to sell a home. There are two types of floor sanders that can be purchased or rented. The first is called a drum sander, and the business end consists of a round cylinder or "drum" with a sheet of sandpaper wrapped around it. The drum spins and drags the sandpaper across the floor, wearing off the old finish as well as shallow scratches and other flaws. Drum sanders are very effective, but they must be kept moving constantly. If the sandpaper spins in the same place for very long, it will sand through the wood and leave a groove that cannot be removed. The second type of floor sander is known as an orbital sander. These machines are designed specifically for refinishing floors. To avoid gouging the wood, an orbital sander uses a flat disc with sandpaper on the bottom. The sander spins the disc and drags the sandpaper flat across the floor. Orbital sanders are lighter then drum sanders, and are often easier to use. When using a floor sander, it is important to understand the numbers used for sandpaper grits. Lower numbers denote coarser paper, good for rough work like removing all the old finish at once. Higher number indicate finer sandpaper, good for finishing the job and smoothing out scratches and lines. You will want to begin with lower grits and then move up as you complete the job. This will result in a beautifully finished floor.


Electrons in an orbital with l equals 3 are in what orbital?

an f orbital


What is d orbital?

The d orbital is the orbital that only applies to the 3rd orbital and up and it contains 10 electrons.


The 3s orbital differs from 2s orbital in that it is?

The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.


according to the Aufbau principle, what orbital is filled after the 6s orbital?

4f orbital


Where is the orbital?

The orbital is in the eye socket.


How a 1s orbital different from a 2s orbital in terms of size?

The 2s orbital is larger than the 1s orbital and is higher in energy.


Is dsp2 hybridised orbital is Inner Orbital Complex?

Yes dsp2 is an inner orbital complex. It involves the inner d orbital.


What is vacant d orbital?

vacant d orbital means an empty d orbital. For example, in nitrogen a d orbital is not allowed whereas in phosphorus a vacant d orbital is present.


What is diffrenec between inner orbital and outer orbital complex?

If inner d orbital is involved in hybridization, it is called inner d orbital complex. and if outer d orbital is involved in hybridization then it is called 'outer d orbital complex'.


Which orbital is nearest to nucleus?

s-orbital


Why is the s orbital fill before the p orbital?

The s orbital fills before the p orbital because it has lower energy, and is more stable.
