Acoustic Tile Makes Bulletin Board That Won't Hurt Wall

"Why not obtain several large panels of acoustic ceiling tile and fasten these to the wall? You could even put up several, treating them like pictures with frames and all. The panels I'm talking about are used in suspended ceilings in offices and should be available at larger lumber companies. The color is off-white and the texture makes them fairly attractive even without posters or photos."

"There are methods to pour concrete on existing slabs to remove the low spots, but they probably aren't inexpensive. You have to make sure that the new concrete bonds to the existing slab. This can be done by roughening the low spot or with special adhesives. Your best bet is to ask a reputable concrete or foundation contractor about your problem."

Acoustic ceiling tiles from suspended ceiling systems offer an effective solution for creating oversized bulletin boards. These off-white textured panels can be mounted to walls like framed pictures and accommodate push pins for hanging posters without causing wall damage. Cork paneling is discouraged due to its messy nature. For concrete patio drainage issues, professional concrete contractors should be consulted, as bonding new concrete to existing slabs requires proper surface preparation or adhesives. Temporary solutions like sweeping remain necessary until permanent repairs are addressed.
