Green Glue Noiseproofing Compound — 5-Gal Bucket is not our standard pick for floors
We stock it under floors, but the manufacturer data we hold covers walls and ceilings. Talk to a Sound Specialist before you size a floors assembly around it.
Green Glue Noiseproofing Compound (5-Gallon Bucket)
Green Glue Noiseproofing Compound (5-Gallon Bucket) is the bulk, viscoelastic damping layer applied between drywall sheets — quieting adjacent walls and ceilings by converting vibration into low-grade heat. Loaded through a follower plate and bulk-loading gun, it installs fast on larger runs and tight retrofits, reducing cartridge waste and lowering the per-sheet cost. One bucket covers approximately 11–12 sheets (~366 sq ft) at the standard 2-tubes-per-sheet rate.
- Serious Noise Control: Viscoelastic damping between drywall layers dissipates vibration — reducing structure-borne and airborne transfer for assembly-dependent STC/IIC improvements in walls and ceilings.
- Pro-Grade Bulk Application: The 5-gal pail runs through a follower plate + bulk-loading gun for fast, repeatable beads. Apply a random pattern, leave a 2" perimeter uncoated, and hang the outer drywall within 15 minutes.
- Big Coverage, Less Waste: 640 fl-oz (≈ 22.9 tubes) treats 11–12 drywall sheets (~366 sq ft) at the standard rate — shrinking cartridge waste and lowering the cost per sheet on larger projects.
- Low-VOC & Jobsite Friendly: Water-based, low-odor formula cleans up with soap and water. Full acoustic performance is reached after roughly 30 days of curing.

Noiseproofing Compound — 5-Gal Bucket Project Calculator
Enter your surface square footage — we'll report how many buckets of Green Glue you need for this page's packaging (each 5-gal pail covers 352 sq ft), plus a recommended mix using our 5-gal bucket, 12-tube box, and single tube.
Bucket coverage assumes the standard 2-tubes-per-4'×8' drywall sheet rate — 16 sq ft per tube-equivalent, 366 sq ft per full 5-gal pail. Add 10% for cuts and touch-ups.

Single 5/8" drywall each side, no insulation, no damping.
- STC 30-39: Loud speech clearly audible next room.
- STC 40-49: Loud speech muffled — normal residential wall.
- STC 50-59: Loud speech barely audible; suitable for offices & multi-family.
- STC 60+: Approaches studio-grade isolation.
