Coloring Finishing And Painting Wood
Fine sandpaper should be used, and it should be handled with great care to prevent cutting thru at corners and other exposed places.
The inexperienced finisher should be warned to sand lengthwise of the grain with light strokes, or his work may be damaged. The sandpaper should not be placed over a hard block and used in that manner, for streaks and spots may be cut thru the filler and perhaps a stain coat that was applied previously. Soft felt blocks should be used, or the paper may be held over the hand for much of the sanding.
Double-coated split sandpaper is thin and flexible, and convenient for some kinds of sanding.10 Fine "Wetordry" waterproof garnet finishing-paper, over a "wetordry" felt pad well moistened with water, can also be used to advantage over filled surfaces. See Fig. 16.
The appearance is often improved by wiping a filled surface with a cloth moistened with benzine as a final operation after the sanding has been completed. Small particles of sand and fragments of wood together with any muddiness from excess portions of filler, are removed leaving an effect of greater transparency as a result of the wiping operation.
137. Certain Woods Require a Paste Filler.—A complete enumeration of all woods that require paste filler would be hard to prepare, but a list of typical species may be of assistance. As a general rule, woods that have open pores or cell cavities that are plainly visible to the naked eye should be filled with a paste filler. A wood that has been colored with an oil-stain containing linseed-oil does not need a paste filler as much as one stained with a waterstain. For this reason woods having fine cell openings, such as birch, are frequently filled after a water-stain; and, generally, they are not filled after application of linseed-oil stain, because the drying-oil mixed with the color sizes the wood and plugs the cell openings to some extent. The volatile oil-stains made from a solvent and an oil-soluble coaltar dye do not size wood much more than does water-stain.
