HELP! DEFT finish on Oak table puddled.
You have a mess on your hands. The poly will adhere if you sand the lacquer
reasonably well--the wrinkling is probably due to oil film left by the minwax being lifted by the lacquer. You have to get a sound base for the poly. However, you are apt to start cutting into the stain when you sand. If you have sanded to the stained surface and it looks ok, then stain again, and if it still looks ok, then just go with three coats of satin poly, with 400 or 600 grit between coats. Let the stain dry a long time, though. There is probably no good reason ever to use Deft for anything. Lacquer is not water resistant, it fights with various substrates, it isn't tough. It does dry fast. You should only use it over water based stain or bare wood. "Harriett Gordon" wrote in message id... I'm refinishing an old oak library table; (donno what was on it originally). Have already used JASCO to strip the finish, sanded, stained with MINWAX oil based stain. All looked good to that point. Then I brushed on DEFT BRUSHING LACQUER. It went on smoothly on the vertical surfaces (legs, sides), BUT THE TOP CURDLED or Puddled or wrinkled- I donno what to call it, but it looks like the finish couldn't adhere all over, but did in spots. I sanded with 400 grit paper, and applied another layer of DEFT, but the same thing happened again. At this point, I've sanded back down to the stained surface. And am wondering what to do next. Can I stain again & apply POLYURETHANE? I'm sure I haven't totally removed the lacquer, and maybe two different products will interact badly. HELP ! |

your laquer reacted to the uncured minwax, to use laquer contact minwax
to see how long it should cure, probably a few weeks. If you use poly remove all laquer but them the legs will have a different finish. Id contact minwax then your finish coat will be the same. |

HELP! DEFT finish on Oak table puddled.
Well, you can rub poly out and it looks pretty nice. And you want a table
top finish to be really tough. "dadiOH" wrote in message ... Harriett Gordon wrote: I'm refinishing an old oak library table; (donno what was on it originally).

Unless it is very, very, veeeeery dry. See instructions on can. You can put poly (ugh) on top of lacquer but not vice versa. You can also put poly (ugh again) on top of oil. See instructions on can. If you want to totally remove the lacquer, use lacquer thinner (it ignites easily) and then sand. Personally, I'll take lacquer to poly any day for appearance. Unless you like gauche. -- dadiOH ________________________ dadiOH's dandies v3.0... ...a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

You should only use it over water based stain or bare wood. Ah, but lacquer looks fantastic. A sheet of acrylic would be just as waterproof as poly and would look about the same. -- McQualude |

At this point, I've sanded back down to the stained surface. And am wondering what to do next. Can I stain again & apply POLYURETHANE? Here is how you can salvage the table... Sand the top down to bare wood and restain, allow to dry thoroughly, apply a coat of blonde shellac and allow to dry, then reapply lacquer. The shellac will seal the oil stain and prevent the wrinkling. Shellac can be bought off the shelf as a liquid, mix the shellac 1:1 with alchohol before applying. -- McQualude |

Premixed shellac is not dewaxed and can interfere with topcoats.
Exception is Zinsser new Sealcoat, I believe that's the name, dewaxed with unusually long shelf life of three years. I buy shellac flakes and mix it fresh avoiding shel life issues. On Sun, 06 Jul 2003 02:09:01 GMT, McQualude wrote: Shellac can be bought off the shelf as a liquid, mix the shellac |

Seal Coat is _dewaxed_ shellac already thinned to a 2 lb. cut. Normal canned shellac has wax which can sometimes cause future top coats from adhering. One more tip, check the expiration date on the bottom of shellac cans before buying! Barry |
