Using a design I’ve done before I did these with purple heart & maple. I found, like other LJ’s, that the purple heart “greys” after cutting & sanding, so I let them get back to the color before finishing. With the concerns of the purple heart darkening, I contacted Charles Neil for any advice he could provide.
Here’s his input -
“This is a tough question and not sure there is any good answer , Purple heart just naturally likes to go brown, like cherry likes to darken, the key is to get as good of UV absorbers as possible to slow the process, but it can still change. There are 2 products that come to mind, one is General finishes Exterior 450 water base finish , and the second is a new System III , marine spar urethane varnish, both are a bit pricy, but seem to have the best UV protection , I would probably go with the 450, because the varnish could also cause the purple heart to change color, any solvent /oil based product can react with the wood and alter the color . Water based products do not react.”
So as before I owe Charles a big thanks for his time & suggestions.
These boxes are about 7”x 4.5” x 4”. 4 coats of the GF 450 finish.
I’ve basically used walnut, cherry & maple before & in my opinon, the purple heart was harder to work with… Although the wood looks good, I don’t know I will use it again.
As always, thanks for looking.
