I’ve finished Purple Heart before and had great results. This time the results are inconsistent. The project sat in the sunlight to get the desired colour. I then added a marine clear finish and here are the results I got. The wood colour isn’t consistent throughout. It’s blotchy.

Does anybody know where I went wrong?

Should I strip it down and start over?

It is wood, nature, non is the same in nature. If you want consistency, go plastic.
Your are too critical of your work.

Wood isn’t perfect, that’s why I love it.

That being said, different types of finish definitely give different results. I would try testing scraps.

This is so true. I think I’ll list this as is and keep notes for later on finishing because I’ve always got lots of scrap wood.
I’m glad I posted.
Thanks guys / gals :)

I always keep notes on my finishes for every project and the final sample piece, labeled to my notes on that/cross reverenced, yes wood of the same type can change it, but anal retentive on finish work. The last 20% of a project is 95% of it!!!!

Notes- yes indeed. Good idea. Just something I never got around to doing but crucial once you start finishing lots of different types of wood
Yep. I’m pretty anal and while it can definitely be annoying, I do make progress because of it.
I just double checked my project against a piece of unfinished Purple Heart and it has the exact same grain pattern characteristics.

It just needs a bit of steel wool and then buffing. Done!

No matter what finish I use I buff it out with OOOO steel wool and the wax of my color choice..

Yep! Steel wool and a wax finish to seal and protect. Then buff buff buff. It turns out crazy gorgeous.
Thanks guys
I guess we all second guess.

Thanks Mr. Bob. When I read your post I howled laughing because I’m hugely self critical and what your wrote was so simple but true.
I had a real ‘Groundhog Day ’ moment so to speak . :D

Anyway today I noticed that the colour has darkened quite significantly which is what I was hoping for which proves that Purple Heart can oxidize after clear finish is added, even with UV blockers.
This is a huge consideration. The smaller the surface area the quicker the colour change so lathe projects need more time in the sun. Rotating the items several times a day for equal coverage is needed.

The main thing is that the customer loves it so it’s been listed.

not only do different finishes give different results, but a piece of wood can have different results with the same finish all along it. look at some curly maple furniture-it doesn’t have any consistency…because its curly maple.

I looked at the pics of that Purdy lil piece for a couple minutes and still don’t see any inconsistency

I agree and that’s the real beauty of wood.
What I was concerned with was that the Purple Heart had turned colour in some areas and not others and I thought perhaps I hadn’t waited long enough for oxidation to occur. I wasn’t sure whether it would keep darkening or not.
Turns out it will keep darkening over time but at some point ( years later ) it will revert back to its brownish colour once more so has to be taken out of the sunlight to slow down this process.
I’m forever fascinated with natures. It never ceases to amaze me.

Have your say...
