Can acoustical ceilings be repainted? How?
Repainting recommendations for commercial mineral fiber and fiberglass ceilings as well as Optima® and Painted Nubby wall panels; includes treatment for cut and tegular edge panels. Most Armstrong ceilings and walls can be repainted by spraying. For touch up, refer to touch-up paint.

Please Note: Vinyl or FL laminated products should not be painted.

Painting Precautions

Armstrong cannot guarantee that the published surface burning characteristics, fire resistance ratings, acoustical performance, dimensional stability/sag, or light reflectance will remain the same after repainting. Field painting will void the warranty.

Armstrong recognizes that ceilings are occasionally repainted and will make recommendations for the type of paint that may be used. Armstrong cannot be responsible for the finished appearance or performance for the field-painted acoustical material.

Spray Painting Method

When painting acoustical materials, the painter should be very careful that he does not close up the acoustical surfaces; perforations, fissures or the DuraBrite® acoustical membrane on the Ultima® and Optima® products. It is through these openings in the surface that sound waves enter the body of the acoustical material and are absorbed. Care should be taken that these perforations are not clogged. At minimum repainting will result in a .05 to .10 reduction in NRC.

First remove loose dust from the material with a brush or vacuum cleaner attachment. Thin the paint only as much as necessary. If it is too thick for proper spraying, follow the paint manufacturer’s recommendations for thinning paint. When spray painting, apply the paint with a stream directed perpendicularly to the surface of the material, moving the gun back and forth to get a uniform coating. Under normal conditions, one coat should be sufficient.

Spray painting will result in a more uniform coating on embossed or irregular surfaces. For best results, panels should be removed from the grid suspension system, laid flat for painting, and allowed to dry thoroughly while still flat before reinstallation. This method eliminates the costly operations of masking walls and covering furniture. It also provides for easier cleaning and/or repainting of the grid while the panels are out being repainted.

With the computerized color matching systems now available, it is recommended that a sample of the ceiling panel to be color matched be taken to the paint store.

SuperCoat™ Touch-up Paint - #5760 and 5761 White Latex Paint

Armstrong SuperCoat Touch-up Paint is intended to hide minor scratches and nicks in the surface and to cover field tegularized edges of mineral fiber and fiberglass panels.

Treating Cut Tegular Edges

All field-cut edges "exposed to view" should be colored to match the factory finish. Armstrong SuperCoat Ceiling Touch-up Paint is recommended.

Directions For Applying #5760 and 5761

  • Remove loose dirt
  • Stir paint before and occasionally during use
  • Apply to damaged areas; avoid filling in fissures and pin holes
  • Quickly wipe off excess paint
  • Drying time is approximately 15 minutes

Will I lose the sound absorption if I repaint the ceiling?
When painting acoustical materials, the painter should be very careful that he does not close up the acoustical surfaces; perforations, fissures or the DuraBrite® acoustical membrane on the ULTIMA® and OPTIMA® products. It is through these openings in the surface that sound waves enter the body of the acoustical material and are absorbed. Care should be taken that these perforations are not clogged. At minimum, repainting will result in a .05 to .10 reduction in NRC.

Will repainting void the warranty?
Yes, Armstrong cannot guarantee that the published surface burning characteristics, fire resistance ratings, acoustical performance, dimensional stability/sag, or light reflectance will remain the same after repainting. Field painting will void the warranty.

Armstrong recognizes that ceilings are occasionally repainted and will make recommendations for the type of paint that may be used. Armstrong cannot be responsible for the finished appearance or performance of the field-painted acoustical material.

Can grid be repainted? How?
I. Surface Preparation

  • Wipe off any dust
  • Remove grease or oil with paint thinner
  • Remove rust with sandpaper

  II. Application

  • Use small pure china bristle for smooth finish
  • Use trim roller for large areas or spray paint
  • For small areas use Armstrong Item No.789512 White

  III. Color Match

  • Contact your local paint store to have them color match a sample of the grid for the best match.

How do I match grid for touch-up?
For small areas use Armstrong Item No.789512 White [view MSDS (PDF)]

With the computerized color matching systems now available, it is recommended that a sample of the grid or color to be matched be taken to the paint store for improved color match.
