wrote: Do I need to concern myself with the type of protecive coat that is alreay on it? Yes. Some finishes (all the good ones) will be fussy. A finish strong enough to survive in this application will place mechanical stresses on a finish beneath it. If that finish isn;t the same, then you're likely to get crackling or crazing. Some (cellulose lacquers) are just chemically incompatible and will wrinkle. Do I sand down to to bare wood everywhere and then re-stain and then apply varnish Yes. How many coats... Depends on your finish. Do I need to sand between coats. Not usually. Most finishes have a "window" where they can be re-coated without sanding. After this window closes, you have to wait much longer until they're really cured, then sand. ..I basically need a really good "How to" This situation sucks, especially the tiny time window. The best way is to remove a few tables at a time, do them off-site, then bring them back in. However you might not be able to do this. If you have to do it in situ, then your _only_ option would appear to be an acid-cure formaldehyde. In the UK I use Rustin's Bar Top finish, a heat-resistant version of their Floorcoat that I use for stripped and sanded floors. This is tough, hardwearing, resistant to mnost spills and works well in service. It also has _very_ fast curing. In a couple of hours it's ready to re-coat, and in six hours you can walk on it. On the downside, it _STINKS_ when it's curing (I wear a full-face mask). You'll need to ventilate the room well afterwards. In this weather that could be difficult. It also needs a reasonable "room temperature" to cure. Your time window is very tight for getting the tables sanded, and having two coats on them in this window. I'd want two teams of people (one sanding, one painting) and a dust curtain to section off the dust from the sanding area. You might also need to leave a few tables with just one coat, then re-coat them in the afternoon when trade is slack. Sort out your sanding machinery too. I'd certainly remove one table from the bar beforehand, and do a trial run on it. -- Smert' spamionam |
