Hi I am new to this site and have been logging quite regularly. I came to notice about this thing called Magnesium board. Have you all heard of it? It's suppose to be fireproof with fibers inside the board. We tried to install it on the walls, so far so good. But my concern is when we used it to install the ceiling, then we paint on it, the paint starting to melt in few months. I couldn't understand as to why would the paint melts, is there any reaction to paint when using magnesium board? is the magnesium board a good product to use in installing drywall and for ceiling? Please help!!!
