One must remember that a key word is "acoustical." Unless the right products are used, a severe loss of sound absorbing qualities will likely occur. Furthermore, ceiling tiles typically lay in a grid system that allows the tiles to be removed for access above the ceiling. Choosing the wrong product can result in the tiles being stuck to the grids when the paint dries.
First, a non-bridging coating material must be used to mantain the acoustics and keep the tiles free and not stuck to the grids. And for sure, a primer coat is the last thing that should be applied to the entire ceiling unless there is no desire to maintain the acustical quality of the ceiling.
A non-bridging material will also leave a very natural appearance as opposed to one that is obviously a paint job. |
