This is a long one. I have been trying to experiment to find the answer to this problem I keep having for months.
There is a problem with my sanding that results in a cloudy, hazy, dusty looking film almost immediately after applying wood stain. (I usually use Minwax oil-based stain, it’s more visible with the darker colors.)
Please bear with me- After several experiments, I am sure it isn’t blushing/humidity issue but rather a sanding issue, and all sawdust has been removed from the wood after sanding.
I have had this problem time and again with both knotty cedar and Douglas fir. (I use this wood for rustic tables, so the knots are kind of vital to the rustic look.)
After sanding normally with 120-150-220 then staining, the entire board appeared dusty and hazy. This was present on both the wet stain and was still there when it was dry.
I’ve tried each of the following experiments on different boards and followed with stain in order to get to the root of the problem, but no matter what I do I always get the same result:
-sanding very lightly 120-150-220
Obviously not sanding isn’t the answer, since I’m left rough, splintery areas. So, after the stain dried, I tried very carefully and very lightly sanding the rough patches. I used 180 grit lightly on some spots, and 600 on others to compare the results.
After vacuuming the sawdust off, I restained the wood, but every little area I sanded then developed the hazy, cloudy look.
I’m at a complete loss. The only thing that helps is Paste Finishing Wax as a finish, but wax isn’t very durable for a tabletop and it the haze is still visible, just diminished.
Is there some trick to sanding cedar or knotty woods I don’t know about? Every time I sand, I get this haze and I have orders to complete with this rustic looking wood, so I’ve got to work with it.
Thank you for any advice or insight.
