The grit size table seems to come directly from here and is not cited in the article. —Preceding unsigned comment added by 140.247.232.78 ( talk) 16:49, 8 July 2008 (UTC)
Is there a method to compute the absolute average particle size in µm? Because when I use the definition and devide 1" = 25,4mm by the paper number I get different values. Off course, I get maximum particle size not average. For my work it would be interessting to know how to compute the average particle size.
Would "Abrasive paper" be a more correct title for this article. It gets a similar number of hits on google and is the generic term. Sandpaper refers to abrasive paper that uses sand as the grit although many people use it as the generic term. Zarboki 10:50, 2 November 2005 (UTC)
Along similar lines, I question the phrase "real name 'glasspaper'". 'Sandpaper' is most certainly a real name, if not the real name of the product in question, and is an unambiguous label that would be recognized by vast numbers of folks. "Originally called 'glasspaper'", or "more accurately called 'glasspaper'" might be more appropriate. PurpleChez ( talk) 17:41, 29 May 2013 (UTC)
I thought regular Al2O3 was a ceramic.
Exactly what was patented in USA in 1834? Sandpaper/glasspaper was being produced before then. Might this refer to a new process or adhesive? Have also added note on Oakey in UK. Ephebi 17:12, 27 November 2006 (UTC)
Does anyone knoe wat that stuff is that cleans the sandpaper? if so can u put it in the page please!!!!
There needs to be a reference of some sort to the statement that 3M invented the waterproof sandpaper. —Preceding unsigned comment added by Tikigod2010 ( talk • contribs) 14:37, 2 June 2010 (UTC)
I think that the term "wetordry" is a registered trademark of 3M. As such, it should include the TM symbol. See their website http://solutions.3m.com/wps/portal/3M/en_US/Marine/Home/Products/Catalog/?PC_7_RJH9U5230GE3E02LECIE20S4K7_nid=GS682WVHR8be4CCRDFQ26Jgl for an example of this usage.

An editor asked on the main article page:
"What is sandpaper grade?! I can't find it anywhere on the internet"
( Piano non troppo ( talk) 10:50, 22 July 2009 (UTC))
Does anyone have good details on 3M's original Wet & Dry? In particular a patent number for it.
I'm finding some contradictions in just why it was waterproof. It seems that there were other abrasives around at this time that were already on waterproof backings (most metalworking emery cloth is, as it's a cloth backing not paper). I suspect that 3M's innovation wasn't to waterproof the backing, so much as the adhesive used. As these were animal glues (I think mostly rabbit skin, for flexibility) these were the real water limit for other coated papers.
I'm also trying to find a 1930s precursor to Micromesh abrasives, developed for polishing early plastics. This was coated onto moleskin cloth, which gave a similar "floating" effect to modern Micromesh, with similar benefits for fine polishing. I think this stuff was made somewhere in Lancashire (near the cloth weavers). Andy Dingley ( talk) 21:57, 19 January 2016 (UTC)
OK Plantsurfer, why is an accurate lead "false"? Andy Dingley ( talk) 00:39, 22 December 2016 (UTC)
Searching the internet, I am having difficulty locating grit size information for ultrafine microgrit papers beyond CAMI 1000. Papers in grades 2000, 3000, 5000, 8000, 10000 and 12000 can be found, but size information for the grit particles of these grades seems nonexistent. If someone has access to a reference for these abrasives, please add them to the table. Thank you. 47.147.7.207 ( talk) 01:44, 7 June 2017 (UTC)
http://wiki.diyfaq.org.uk/index.php/Sandpaper appears to be remarkably similar to this page. Is this page ripped off there, is there ripped off here or are both ripped off somewhere else? Neither lists the other among its references. -- 86.5.88.131 ( talk) 22:17, 27 August 2021 (UTC)
not sure if there is an official formula for these but they're not random and cracking open excel one can easily derive the exponential equation used (i used excel's autofit)
for CAMI/US: particle diameter = 35733*(CAMI grit)-1.195 (R² = 0.9899)
for ISO/FEPA: particle diameter = 18510*(ISO grit)-1.017 (R² = 0.9943)
the imperfect R² is probably due to rounding

Given the recent merge, in which it was decided that sandpaper is the COMMONNAME for a coated abrasive, it now seems sensible to merge two other stubs to this page: Crocus cloth (a type of coated abrasive used in jewelry-making) and Emery paper (a type of sandpaper with a particular abrasive). The proposal is on the grounds of short text and context. Klbrain ( talk) 11:07, 17 December 2022 (UTC)
If anybody were comparing the "grit" notation with "x/0" notation for emery paper, here is a short reference: https://cafa-info.org/page/GritSizesForEmery It should be better sourced and included in the main table, though. FDominec ( talk) 16:06, 9 November 2023 (UTC)
