Grille Painting Guidelines
The ECS Edgeless In-Wall Speaker grilles are paintable and can accept
virtually any type of paint. We strongly recommend the following:
1. Remove the grilles from the speakers prior to painting them.
2. Thin the paint prior to application, if needed. Spray and roller paint
applications typically provide the best results. Note that you may
need to apply
multiple thin layers
of paint to achieve the desired
shade without losing sound quality due to clogging of the grilles.
3. Let the painted grilles fully dry before mounting them back on the
speakers.
