Hopper Gun for Knockdown: Decision Point
A hopper gun can help apply the mud quickly and more evenly for a light to medium knockdown. I find for heavy knockdown with patterns hand application is better. The main question I would ask , do you have a compressor that will provide the flow at the listed gun pressure requirement? My last comment would be Do not use hot mud in a hopper it drys faster and is harder to clean the gun. If you want what I consider a medium to light knockdown a hopper gun is a great time saving tool. Make Sure to clean the gun well after use and it can last for years and many projects.
