Monoglass®can be applied to most surfaces, however all surfaces should be inspected to ensure they are dry, clean, free of oil, grease, dirt, loose paint, mill scale or other deleterious material that would impair bond or cause staining of the product. The Monoglass® surface can be left untamped for conventional finishes or tamped and over-sprayed for flatter finish.
