I wouldn't call it a surface coating. It's over, under, around and between the bunches of fibers. The mat gets soaking wet with epoxy. I know because I have done it. That's why I thought it worked. I soaked the mat then put it in the void and there was epoxy all through it. But I didn't know that the mat should have started pretty much disintegrating. But this is from what I read the other day and I could just be digging my hole deeper.
