Why do people use sandpaper?
Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, either to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).
Does liquid sandpaper really work?
Using a liquid sander also helps get into any nooks and crannies that you may not be able to get at with sandpaper. If you’re working on a piece of furniture with a lot of etched detail, using liquid sandpaper/deglosser may save you a lot of time and provide the best results.
When should you stop sanding?
Typically you will want to stop at 180 or 220 if you are planning to stain the wood. Higher grits will close the pores of the wood and make it difficult for stain to penetrate.
What direction should you sand?
Always sand in the direction of the grain–never perpendicular to it or at an angle. This also applies when working on edges and hard-to-reach corners. Scratches made by sanding against the grain will look unattractive on the finished piece and will be particularly noticeable after staining.
What is 80 grit sandpaper used for?
40 – 80 Grit: Coarse. 40 to 80 grit is used for heavy or rough sanding and to help remove scratches or imperfections. While it is okay to be abrasive, take your time when using a low-grit sandpaper because it may show noticeable scratches or swirls in the wood.
What is 50 grit sandpaper used for?
Coarse grits are typically in the 40- to 50-grit range. Medium sandpaper, ranging from 60- to 100-grit, accommodates some final shaping.

Is higher grit a finer?
The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper. The higher grit number is equivalent to a finer abrasive, which creates smoother surface finishes. Lower grit numbers represent coarser abrasives that scrape off materials much quicker.
Can I go from 40 grit to 120 grit?
Selecting the right grit sandpaper For heavy sanding and stripping, you need coarse sandpaper measuring 40 to 60 grit; for smoothing surfaces and removing small imperfections, choose 80 to 120 grit sandpaper. For finishing surfaces smoothly, use extra fine sandpaper with 360 to 400grit.
Which sandpaper is best for wood?

How do you sand a door trim?
Sanding Tip: If the trim is new or already smooth, lightly sand using 120-grit sandpaper until all shine disappears from the trim. If the trim is rough and worn, start by sanding with coarse, 80-grit sandpaper. Then, move to less-coarse sandpaper such as 100- or 120-grit to smooth the surface.
