Hello everyone, I have a problem I was hoping someone could shed some light on.
I’m using a roller to apply a varnish to a test-piece of pine, before using it on a real piece of walnut.
I’ve never used a roller before, only a spray, and I have very little experience with finishing in general.
I should note that I don’t know if i’m using lacquer or varnish, as my first language doesn’t have that distinction, but the substance is originally made for boats, if that gives you a clue.
Here is my problem: Between layers of varnish, I sand the peice with grit 240 sandpaper, using a cork sanding block.
But the sandpaper draws visible lines into the lacquer, and to in an attempt to remove them, I end up sanding all, or most of the lacquer off! Below is an image that shows the surface of the test peice after sanding the lacquer.
This is my second failed attempt at applying the lacquer to this piece.
Should I sand more carefully? Use a finer grit perhaps?
