How long does whiteboard paint last?

Premium brands like IdeaPaint last 5-10 years with proper care. Budget options may start ghosting after 1-2 years. Avoid using permanent markers, and clean with whiteboard spray weekly to extend life.

Can I apply whiteboard paint over existing paint?

Yes, but the existing paint must be smooth and well-adhered. Lightly sand the surface, apply primer, then the whiteboard paint. Peeling or textured existing paint must be scraped and smoothed first.
