Ask about sandpaper Hello
Looks like there are different types, grade and appearance of sandpaper in the market. I'd like to know if I can just use any of them on any surface? If I want to
be more professional and caring for my things, do I need to study the types
or grades of sandpaper and the corresponding materials that it should be sanded?
For example, if a sandpaper is made for wood surface, does it usually work great
on any wood surface?
You need to know the grade for the job, the lower the grade the rougher and harsher the cut. 80 grit is good for fast removal and an aggressive cut. 120 to 150 suitable for paint and plaster on walls. 240 grit is ok for a light sand of paint. Plenty of online info including if you start with a 40 grit and want to end up with a 400 grit finish you have to go through the grits to get there.
Not sure what types of paper you have access to in Singapore, this is an Australian site so it may differ.
Below is a good article that explains the differences in the paper, generally designated by the colour of the paper.

How about quality of material to be sanded?Originally Posted by johnc
Should I use a different sandpaper to sand wood and plastic?
You will use finer grits on plastic, however it is a product that does not like sanding
If I am going to sand cedar block for refreshing the smell of it, what is the sandpaper I should use for the best result??
For the smell you are better off using a sharp hand plane.
