You can use different grains of sandpaper, but the size of the paper itself must conform to the dimensions of your sander.
You may use a sander to smooth the surface of wood. You should sand against the grain of the wood, using. If you do not have an electric sander, you can use sand paper wrapped around a sanding block and do it by hand.
What kind of sander? what grit sand paper are you useing? do you have a dust collector? you need to have a lot more info to get a answer!!
I don't know if the pros recommend it, but I've used my orbital sander with fine (150 grit) paper. I attach my shop vac to the sander's output and even vent the shop vac out a window for a near dustless sanding job. You do have to be careful. Even light pressure on the sander can eat through the mud very quickly or rough up the drywall paper and tape.
Silicon carbide paper is used for sanding and smoothing surfaces like wood, metal, or plastic. You can attach the paper to a sanding block or a power sander and then apply light pressure to the surface you want to sand in a back-and-forth motion. Make sure to use the appropriate grit size for the level of sanding required.
It cannot be used on sander
Different grades of glass paper have varying levels of coarseness or fineness, which determine their effectiveness for different sanding tasks. Coarser grades, like 40 or 60, are used for heavy sanding, while finer grades, like 220 or 320, are used for smoother finishing. Selecting the appropriate grade of glass paper ensures a more efficient and effective sanding process for a specific project.
Sanding a piece of paper is a physical change because the paper's appearance and texture are altered, but its chemical composition remains the same.
A sanding block is basically just a small piece of wood or other material covered with a sanding belt or sand paper.
I have tried scraping the finish with a metal spatula then sanding with a sander. However the old varnish is "sticky" or "gummy" and just gums up the sand paper. Any idea how to more easily deal with this problem? The surface of the counter always feels sticky from the deteriorated finish!
You take a electronic sander and glue and paper to it. Then you sand the tip down Do not understand "glue and paper to it". Please clarify.
Sandpaper grits range from coarse (around 40-60 grit) for heavy sanding and removing material, to medium (around 80-120 grit) for general sanding and smoothing, to fine (around 150-240 grit) for finishing and polishing surfaces. Ultra-fine grits (above 240) are used for very fine finishing work.
sand and paper Don't forget the glue. To hold the sand on the paper. Though if you don't have actual sand paper at home, using a brick or rock to rub the surface that needs sanding is a good way to start. For smaller areas a nail file can be used. Commercially made sandpaper for consumer use is generally made using a stiff cardboard or paper backing. Glue is applied to one side, and the sanding medium is electrostatically applied. Sanding mediums commonly include crushed silica and titanium oxide.
