This is the 4th coat. All previous coats dried for 24 hrs. If I spray water on top it beads up and is perfectly dry.

For whatever reason im seeing streaks in my finish where i used a folded up lint free cloth. I kept a wet edge and didnt go back over an area i had already wiped on. Im confused.

Any thoughts?

I’m thinking it’s due to the flattening agent not being distributed evenly.

I am following this thread with great interest.

Is it possible that the wood surface was sanded too smoothly that your stain can not penetrate it?

Well the stain was very even, its only started looking like that after the poly went on.

may have gotten condensation on the drying finish.or on the rag.maybe even sweat on your hands going though damping the cloth.

I share Timberwerks view about flattener distribution. I speculate that your wipe on rag applies a tiny bit more pressure at the “wads” than between “wads”. That wipes a tiny bit more of the flatner impregnated finish off of your work. I always apply gloss top coat for as many coats as I need to get the depth I am after, then apply the final topcoat of the sheen I want. That coat can go on a little thicker so doesn’t need to be wiped as “dry” as if it was an intermediate coat. I could, of course, be absolutely dead wrong about this.

I think Roger and Timber may be right. I had someone else tell me they thought it looked pretty glossy for semi gloss, and got me thinking you know it is a little bit glossy. So maybe it is the flattener not being distributed very evenly.

Maybe its due to your theory Roger, i’m not sure.

I just tried a sample of using 50% mineral spirits and 50% finish and did a very thin coat, and one side i circle rubbed it in, and the other i did long strides like i did before. This time the circular looked AWFUL, and the long strides looked actually better than it did before.

Also when I think back to my first initial coat, I applied it with a foam brush and it came on super thick cause those foam brushes, well maybe its my technique, but i could only do heavy coats. ANd that coat came out perfectly even.

I think adding thinner helped by letting their be less solids to be distributed unevenly
I think doing thicker coats allowed the flattener to be distributed more even with more open time to level out.

Why have I never had this issue before? Not sure. And I guess when you apply each layer it re-desolves the previous layers and relevels the flattener??

Should I give it a good sand, and do two thick coats? Get a diff finish thats brand new?

Semi gloss finishes will streak like this if you apply them with too much pressure. It unevenly distributes the matting agent.

Use very little pressure or, wipe off the excess poly more completely. At this point there is no way I know of to fix it without sanding down to wood. Fwiw, only the last coat needs to be matte.
