Hello all, Thank you for taking the time to read my post. I’ve come up against a perplexing problem with a recent piece of work that I completed. It is a walnut piece that was finished using a Maloof style 3 part varnish and then topcoated with Linseed Oil/Beeswax. The piece cured for over a month in my shop and looked beautiful. I delivered the piece and went back a week later to deliver something else and noticed the finish had spotting everywhere. My first hunch was that the humidity levels of this space felt quite different than the shop so maybe there was a reaction with the wax and it was weeping and clouding on the surface due to it being cooler and damper. My shop is generally always 65 and 40% humidity. The home is a modern space with lots of concrete and windows. It is generally kept at 65 temperature, I have not measured the relative humidity of the home yet, but I suspect due to the concrete and proximity to a large lake that it is probably much higher.
The breakdown… I put 3 coats of Linseed/Tung/Poly on the piece – it looked great. I then put 2 topcoats of Linseed/Beeswax – looked gorgeous and silky like always. It then cured for one month. Delivered the piece, everything still looked as it had. Returned after a week and saw spotting everywhere. Rubbed the entire thing down with steel wool and it looked beautiful again with a nice even sheen. Returned the following week and spotting had returned. It was much better, but still present. Used Naptha and steel wool for a next complete rub down and attempt at removing any wax that was possibly the cause. After rub the down it looked great again. Returned today and found more spotting. Each time it seems to get a bit better, but it’s still returning and isn’t acceptable.
Thoughts???? I’m really at a loss and don’t know where to head from here. This is a finish I use on all of my furniture of this nature and I’ve never had a problem. I didn’t try anything new, or use different brands. Everything was new or recently new as far as the products that were used.
Unfortunately I don’t have great images but I do have one image that I think sufficiently shows the uneven finish and spotting or streaking that is occurring.
Thanks again for any feedback and help on this. Much appreciated.
