Sound Diffusers in an Auditorium (Noise Control Products Application)
Acoustical Solutions shows how adding noise control products such as sound diffusers to a large room can reduce the echo without creating a 'dead' space. For this project, we used Barrel™ Diffusers.
- Can the Barrel Diffusers be painted?
- How do I paint Gelcoat Finished Diffusers?
Yes, and this will not affect the acoustical performance of the product.
Clean gelcoat finished diffusers with wax remover, acetone or something similar. Next, use 3m red colored Scotch Bright scuff pad. Scuff surface with scuffpad until all shine is gone using a circular motion. When scuffing is complete, clean the surface with a damp cloth and let dry. It is now ready for paint. Paint with an air tight gravity feed paint gun, and a water-based paint.
