The ceiling tiles you use to get a fall ceiling has to be lightweight; therefore, the majority of them are made from fiberboard, which is a mixture of wood fibers, chemicals and adhesives to make the tiles fire-resistant. Lightweight fiberboard readily absorbs water, and that means you require specific paint to touch up chipped or soiled shingles.
The very best Touch-Up Paint
Ceiling tiles come in generic white and off-white colours, and therefore do the touch-up paints that traders sell to mend them. However, you can get paint tinted to match your shingles. The paint is a high-solids latex blend diluted with propylene glycol instead of water. Manufacturers use this solvent to prevent emulsification of this fiberboards; you should avoid touching up ceiling tiles with waterborne paint.
You can spray or brush on ceiling tile, but for touch-ups, a brush is usually easier. Wash the area you’re about to paint with a rag; then dip a small synthetic-bristle brush in the paint and dab the area. Immediately wipe off the excess, and await the paint to dry which typically takes around 15 minutes — before applying another coat.
