CHAPTER I.
GROUND-WORKS FOR GRAINING

THE following remarks, while not claiming to be anything new or startling, will perhaps be of interest to those who seek to improve themselves in the modern style of imitating the grain of wood. The ideas set forth in these pages are founded on the observation and every-day experience of a grainer to the trade who does not claim to be the best in the world, but who offers his suggestions for the good of the craft.

Graining is often overlooked in the rage for stained white wood or olive greens in interior work, but it will always find favor with those who have experienced its wearing qualities as compared with plain painted work; for should the varnish be of good quality and not crack, the work, if properly done, will stand for years and will not fade in the manner that paint does, and where the work is properly done on new wood it cannot be chipped off unless the wood is taken off with it. It can be scoured off, but will not come off otherwise. Where graining is done over old paint or over work that has been previously grained the case is different, as, if knocked or bruised, it will chip off to the coat beneath, and where the work has formerly been white the effect is very bad and is hard to remedy; but if care is taken when grounding the work, it may to a great extent be prevented.

In preparing old work for graining one of the first things requisite is to have the surface made as smooth as possible; this may be done with sand-paper or—what is better—lump pumice stone.

In case the graining is done over old paint that has cracked the best thing to do is to remove the old varnish or paint by the application of a strong solution of washing soda or a weak solution of potash. Some painters use spirits of ammonia or burn off with a burning-lamp. After thoroughly softening or removing the old paint or varnish with either soda or potash, the work should be washed off with a weak solution of vinegar (about a pint of vinegar to a pailful of water), in order to remove all traces of the alkali and prevent its future action on the paint. Some painters think that this is too much trouble and assert that they cannot get paid for doing work in this way, but in the end it will prove to be the best way, as it will greatly add to the appearance and durability of any job so to prepare it. In any case the work should be thoroughly sand-papered and made as smooth as possible before receiving the first coat; this, of course, is for old work. The ground-color should be thinned with about half spirits of turpentine and half oil, with the addition of sufficient drier for old work, and oil, with an extra quantity of drier, for first coat on new work, using some spirits for the second and third coats.

The writer has found by experience that on the cheapest jobs (of two-coat work) where the wood is sappy and the work has been rendered rough by the painter using a large quantity of drier in his priming coat, a much better surface is made to grain over by this method. It will not spot or look cloudy when rubbed in to grain, as two-coat work often does on new wood.

A little "elbow-grease" and sand-paper between coats make a vast difference in the looks of a job when finished, and the ground-work should always be lightly sand-papered before it is rubbed in by the grainer.
