What about finishing exotic woods?
It is often difficult to find an answer on finishing exotic woods so I asked Michael Dresdner for any suggested reading or tips.
Q: Have you published anything on finishing exotic woods?
A: I have published four books on finishing. All deal with exotic wood to some degree, but the truth is that with very few exceptions, finishing exotic wood is no different than finishing domestic wood. The notable exceptions are those woods that belong to the genus dalbergia. These include all the true rosewoods, cocobolo, kingwood, African blackwood, and a few others. The only problem with these woods is that they contain an antioxidant that will prevent curing of any finish that uses oxygen polymerization. Among small shop and hobby woodworkers, that includes all oil based finishes; on the industrial side, it includes polyester and UV cured coatings.
To get around the problem, simply seal the wood first with Zinsser SealCoat after which any common coating will cure over it. With polyester and UV coatings, vendors typically offer a cross linking sealer specifically paired to their coating.
