So, I'm carving a wooden pendant for my girlfriend. I want the finish to be satin. However, since she plans on wearing it all the time, I want it to be water resistant. I do not want the wood to get ruined because of the water from her daily baths. What kind of finish should I use, so it lasts a lifetime and gives it a satin look? Lacquer or Polyurethane or something else? (I'm willing to settle for a gloss look as long as it lasts a lifetime.)

  • Unless you coat this with a uniform and fairly thick coating of something 100% waterproof you can't get this to stand up to getting wet daily. This is really only possible with the level of coating that's used for example on exterior boat surfaces. – Graphus Mar 27 '18 at 14:41
  • And NO finish in existence will last a lifetime in this context, even the very toughest finish I'm aware of will I expect give you, at most, about 10 years. The alternative is to use a wood that doesn't need a finish at all, just has a sheen from being finely sanded and/or buffed, and then there's no finish to wear through. What species of wood do you have available to you? – Graphus Mar 27 '18 at 14:44
  • Something like an epoxy or CA finish might be the most durable. Whatever you use will not hold a satin sheen forever, though. It will naturally get polished through wear over time. – SaSSafraS1232 Mar 27 '18 at 17:46
  • @Graphus I have rubber wood, teak and rose wood available to me. I don't mind having to refinish it every 5 or 6 years. But when finished each time, I want it to give maximum protection till I refinish it again. Considering this, what kind of finish should I use? – Shreesha Hegde Mar 29 '18 at 3:31

    Unfortunately 'lacquer' can now mean many different finishes with a wide range of properties. At worst you could get wear off edges or high spots in just a few months, at best it might last a couple of years. But since you have teak & rosewood available to you I would choose either of those over rubber wood any day because they're both much harder (and IMO look better too). Rosewood is a great example of a wood that doesn't need a finish on it to look good, quite a decent gloss can be achieved by buffing the wood itself and this will improve with wearing/ handing as long as it isn't washed. – Graphus Apr 1 '18 at 14:44
