Anyone know how long it takes for Jatoba to regain its color after sanding? I’ve seen some darkening after leaving pcs in the sun a few days but nowhere near the unsanded color. The weather here is foggy and cool until about 11 am so I can only leave them out from then until 6 PM. My intent is to finish with Bulleye Shellac but it says it won’t darken with age.

John, Jatoba will darken with exposure to light. As for how long this will take it is really a difficult question to answer since it will continue to darken with light exposure and there is no way to really guage how dark the wood was before you started working on it.

Just to give you an example though, we put brazillian cherry flooring down in the family room. My wife enjoys moving furniture around because she enjoys change for the sake of change. When she moved the couch and area rug after the floor had been down for 3 months there were distinct outlines of the furniture and rug on the floor with the exposed areas being much darker than that couch area which was shielded from light. So the bottom line is that the jatoba will get back to its original color in time.

Zinsser’s statement that the shellac will not darken with age does not affect the response of the jatoba to light exposure.

Thank you for the response. I’ll keep putting it in the sun whenever it decides to show its face – until the reddish color starts coming back.

I don’t know about Jatoba but if it’s anything like Coccobolo the colour should back surprisingly fast. I was making some pistol grips for a friend and was very disappointed by the change in colour after shaping. After two days in the window sill in my kitchen the colour was more vibrant than ever. This is just my experience, good luck with the Jatoba!

John,

Try using boiled linseed oil on a piece of scrap and see what that does for you. It should darken it considerably.

Blair and Steve – Thanks – I’m trying the window sill option since yesterday since the sun never came out! It’s the end of July and the high was 65 degrees. So now 1 pc has had 3 days in sun and 1 in the window sill and not half as dark as it was originally. If by the weekend I’m not happy I will try the linseed oil. Maybe next time I’ll try Coccobolo

John,

Next time try cherry. A few hours in the sun and bol, and it looks 100 years old. Or, if you really like RED wood, try bloodwood. Don’t finish it in the conventional way. Sand through 2000 and wax using a mixture of beeswax, mineral oil, and boiled linseed oil. Rub in, buff out (wax on, wax off), and GET OUT OF THE WAY! It’s a little pricey at most places, but Vienna Hardwood, www.viennahardwood.com has 4/4 for just $5.50/bd.ft. It’s hard, strong, beautiful, works easily, and the red lasts. Cocobolo, on the other hand, is about $16/bd.ft, is hard to glue, will not accept most finishes except wax-which is fine-and gets darker and darker-almost black-with age.
