it has those small holes in it and is white and cardboard backing and is about 10 inches by ten inches.
you know, I would not think that this is actually cleanable at all as the thin white lam would come off, But, I do know that it is paintable and you don't need to prime it unless yours is very dirty and greasy for some reason. It would present itself better if it was sprayed, but a roller could be just fine. On the first coat, this stuff might soak up the paint big time. Of course, do not use oil based paint, use a good quality latex paint.
