Guide on Sandpapering?
Wooden surfaces to be stained or painted may usually have major roughness already removed, but are seldom smooth enough and may require sand papering to be entirely sure of first class result. As with other seemingly simple operations, there is a right and a wrong way of doing this, and the importance of doing it properly are not always appreciated.

Providing the woodwork feels only slightly rough when the hand is passed lightly across it, fine sandpaper is generally most suitable. It should be held perfectly flat against the surface; when large areas have to be papered, a flat piece of cork, wood, or rubber can advantageously be employed as a pad, and the sandpaper wrapped around it will be kept in level contact with the wood. Ready-made sandpaper-holders are obtainable and are very useful.

The most important points to observe are to maintain even pressure and never to rub across the grain of the wood. If undue pressure is exercised on any part of the Work, there is risk of leaving a faint hollow or depression, which, though it may not be obvious at the time, will probably be quite noticeable after the finishing operation has been completed. Unless rubbing is done up and down the grain, when applying stains, the stain may dry out patchily, with some parts darker than others.

A 97 Sandpaper

Sandpaper is graded from very fine to coarse. Sheets are code numbered on the back to indicate the degree of coarseness. For most work a medium grade is adequate.
