Venetian Plaster Media Walls, Planning, Finishes and Avoiding Cracks

Venetian plaster media walls in living rooms, a living room with textured plaster walls

A media wall is a built out wall that holds the television, often with an electric fire, shelves and hidden cables. Most are built from timber or metal studs and plasterboard, then painted. Finishing one in Venetian plaster turns it into the centrepiece of the room. This guide covers how to plan a Venetian plaster media wall, which finishes suit it, and the details that stop it cracking.

Plan the wall before the plaster

  • Build it rigid. Studs at close centres and well fixed boards reduce movement, and movement is what cracks a finish.
  • Plan the cables and sockets first. Once the plaster is on, cutting in a new socket leaves a repair.
  • Follow the fire's manual. Electric fire insets come with installation instructions covering clearances and ventilation. Build to those, and keep any finishes the manual restricts out of those zones.
  • Think about edges. Shelf recesses, returns and corners are where the finish shows its quality. Clean, straight edges make the wall.

Preparing plasterboard

Tape and fill every joint, set and fill the screw heads, sand smooth and prime. Board joints are the most likely place for a hairline crack to appear, so reinforce them properly. Our guide to Venetian plaster on plasterboard covers this in detail.

Which finish suits a media wall

Colour

Darker colours make the television screen blend in when it is switched off, which many people like on a media wall. Warm neutrals suit rooms with timber and soft furnishings. Always approve a sample first. See our colour library.

Questions

Can you put Venetian plaster on a media wall?

Yes. Media walls are usually plasterboard, which takes Venetian plaster well once joints are filled and the board is primed.

Will Venetian plaster crack on a media wall?

Not if the frame is rigid and the board joints are reinforced. Cracks almost always follow movement in the wall behind.

Can I do it myself?

A media wall is a good size for a first project. Read how to apply Venetian plaster, or have our installation team do it for you.
