Can someone either briefly explain how to skin coat, or link me to a good explanation. Thanks.
It's skim coat.
You're right. Someone else used the expression 'skin' coat and after I posted the message, I looked it up and now I know it's "SKIM" coat. :-)
Let the painter do it right.
The painter came in and spackled and sanded. I suppose that is not considered skim coating, is it?
