Frequently asked questions
Dust and loose dirt may easily be removed by light brushing or with a vacuum cleaner. The best attachments to use are the ones for cleaning upholstery or walls. Make sure to clean in one direction only to prevent rubbing dust into the surface of the ceiling.
After loose dust has been removed, other marks can be easily erased with an ordinary eraser. Although, a fresh wall cleaner may be preferred.
Mineral fiber ceilings may be cleaned with a moist cloth or a sponge dampened in water containing mild soap. The sponge should contain as little water as possible. After washing, the soapy film should be wiped off with a cloth or sponge slightly dampened in clean water.
All of our mineral fiber ceiling tiles and panels can be painted with latex paints. The front and back of 24-in x 24-in and 24-in x 48-in panels should be painted.
PLEASE NOTE: Field painting will void the warranty. We cannot guarantee that the surface-burning characteristics, fire-resistance ratings, acoustical performance, dimensional stability/sag, or light reflectance will remain the same after repainting. TECTUM tiles can be painted up to 6 times without losing acoustical performance.
