Steam Swelling

Steam usually does a better job of swelling the wood than water alone. To steam a dent, apply water to the dent as in the

HOW TO REPAIR A guest places a WATER RINGS glass on a lovely ta-ON FINISHES hie top, and later you find a white ring where the bottom of the glass rested. It is a discouraging sight. The whiteness is called "blooming." which occurs because the finish absorbs the moisture from the bottom of the glass. Lacquer and shellac finishes bloom readily. Some varnishes w ill bloom, but not as easily. Blooming also shows up as a milky look on the finish of furniture that has previous paragraph. Then place a very moist cloth on the dent and touch the tip of a hot iron to it. Hold the iron in place long enough to create steam not only in the cloth but also down into the wood. This should cause swelling of the wood. One application may raise the dent, but you been stored in a moist place.

Most blooming takes place on the surface of the finish and doesn't go very deep. To get rid of blooming, you must remove that liny fraction of the surface of the finish which has clouded. The best way is by means of a mild abrasive. Any of the following, ruhbed gently into the bloom until it disappears, will work:

  • 1) rottenstone mixed with mineral spirits;
  • 2) pumice and fine oil;

probably will have to repeat the procedure several times. One problem this technique sometimes creates is "blooming," a white area where water has soaked into the finish. This problem is solved in the same way as the removal of water rings, which is described next.

  • 3) fine 4/0 grade steel wool:
  • 4) powdered dentifrice;
  • 5) cigar ashes used as an abrasive.

If the bloom goes very deep, the rubbing will take some time, and you might have to switch lo a harsher abrasive — to a 3/0 steel wool, for example. But longer rubbing with a mild abrasive is better than quicker rubbing with a harsh abrasive, because you will do less damage to ihe surface. You want the repair to be as un-noticeable as possible

Moisl cloth

One way to fix a shallow dent is to steam it. Apply water to the dent; cover with a moist cloth Touch the cloth with the iron so that the steam can get down into the wood.

FIXING A SMALL The technique in-BLEMISH OR AN volved in repairing ALLIGATORED lacquer and shellac FINISH finishes is called

"reamalgamation." In it. a solvent is applied to the finish to cause the finish to soften and spread over the surface. The two most important uses of this technique are in the repair of small finish blemishes and in the restoration of finishes that have alligatored.
