Green Glue & Textured Walls / Ceilings

Posted by BIP on 16th Dec 2020

Green Glue Noiseproofing Compound is a great soundproofing product which dampens sound transmission through walls, ceilings, and floors.  Green Glue is installed between two layers of rigid materials, which is commonly drywall for walls/ceilings and plywood for subfloors.  Green Glue is a liquid material that spreads between the two layers when they are fastened together tightly with screws.  After 3-4 weeks the water in the Green Glue will evaporate and the compound will become a gooey sticky substance that cushions the two layers of material and damps the sound transmission.  

A common question we are asked is about using Green Glue on textured walls and ceilings.  If you have an existing textured wall or ceiling, adding Green Glue Noiseproofing Compound and a new layer of drywall will not work as effectively due to air pockets being left between the two layers.  These air pockets are caused by the texture and will allow the Green Glue Compound to spread into the pockets rather than the high points of the texture.  This will cause less than stellar results sound wise.

Green Glue and Textured Walls / Ceilings

Examples of types of Textured Walls/Ceilings that cause issues with Green Glue:

  • Popcorn Ceilings 
  • Stucco
  • Knock Down
  • Orange Peel
  • Adobe/Santa Fe
  • Cats Paw
  • Swirl Mark

Our best solution would be to remove the texture as best you can.  This is usually done best by sanding down the surface.  Once your surface is relatively smooth, then you can apply Green Glue Noiseproofing Compound as normal.
