The details..

'Sandpapers/glasspapers - types and their uses' is a practical guide that covers everything you need to know about sandpaper. The book explains how true 'sandpaper' has been replaced by backing sheets covered with glass, aluminium oxide, silicon carbide, garnet or other specialist grits. It also discusses the importance of choosing the right type of grit for specific applications.

The book goes into detail about the characteristics of each type of grit material such as its size which ranges from very coarse (40) to very fine (over 400). Additionally it explains how adhesive plays an important role in ensuring strong bonding between the backing sheet and abrasive grain.

Readers will find information on three common types of backing materials: ordinary paper which is relatively cheap but adequate; waterproof paper that's essential when using lubricants; cloth used where flexibility is required during use. Adhesives may be water-soluble or waterproof depending upon whether wet-and-dry sandpapers are being used or not.

Lastly readers can learn about different forms in which sandpaper comes like sheets sold normally in packs suitable only for hand-sanding; rolls available in single grades sold by linear length produced mainly for power tools but can be used manually too ; discs designed specifically for rotary sanders or other power tools requiring stiff yet flexible backings; belts meant exclusively for belt sander machines varying according to width & length etc.
