Frequently Asked Hopper Gun Questions
Can all purpose drywall joint compounds be used for drywall walls and ceiling texturing material (except acoustic/popcorn materials)?
Answer: Yes, but the all purpose joint drywall compounds must be thinned down with water.

What is the mixing ratio of water to all purpose drywall joint compounds when thinning down all purpose drywall joint compounds for use for drywall walls and ceiling texturing materials (except acoustic /popcorn texturing materials)?
Answer: The mixing ratio of water to all purpose drywall joint compounds to produce walls and ceiling texturing material is: 1/3 gallon of water for each 1 gallon of all purpose drywall joint compounds.

What type of texturing material should I use to achieve an acoustic/popcorn texture?
Answer: Acoustic/popcorn texturing materials are manufactured with the inclusion of Styrofoam pellets in the texturing materials. It is normally sold in bags as a dry powder.

Are there any mixing suggestions for acoustic/popcorn texturing materials?
Answer: Yes, we suggest mixing one to two cups of all purpose drywall joint compounds into each gallon of acoustic/popcorn texturing materials. When mixed the acoustic/popcorn texture material should have the viscosity and appearance of oatmeal.

Can I mix paint into my texturing materials instead of water and eliminate painting the wall or ceiling after the texture applied?
Answer: No, all textured walls need to be painted after texturing to seal and preserve the textured appearance.

How come when applying acoustic/popcorn materials to the ceiling all I get is liquid coming out of the hopper gun and the Styrofoam pellets are lodged in the neck of the hopper?
Answer: The liquid component of your acoustic/popcorn texturing compound is too thin. See mixing suggestions for acoustic/popcorn in this section.

What size are the o-rings on the Air Stems and Adjustable Stops on the Texture Pro 200, Spray Pro and Wal Pro Hopper Guns?
Answer: The o-rings used on the Air Stems and Adjustable Stops of the subject hopper guns are referred to as a size 13, they are 7/16” ID, 9/16” OD and 1/16” thick.

What size are the o-rings used on the Air Stem and Adjustable Stop on the Spraying Mantis Hopper Gun?
Answer: Even though the o-rings on the Air Stem and Adjustable Stop of the Spraying Mantis Hopper Gun is originally supplied with metric o-rings the size 13 o-ring used for the other Wallboard hopper guns Air Stems and Adjustable Stops will work in this application.

When I hook up the air supply to my Texture Pro 200 the air flows through the hopper gun even when the Trigger is not pulled?
Answer: For the Internal Shut-off Valve of the Texture Pro 200 Hopper Gun to work properly there must be a material orifice and the Orifice Nut installed on the front of your hopper gun before attaching to your air supply.

How do I achieve an orange peel texture (any model Wallboard Hopper Gun)?
Answer:

Referring to the Texture Table of the Operating Instructions for your hopper gun:

Mixture – Thick Paint

Orifice – Medium 1/4" (Mantis – 6mm)

Pressure – 20 – 23 PSI

Trigger Pull – 1/2   

How do I achieve a knock-down texture (any model Wallboard hopper Gun)?
Answer: Any texture pattern from medium splatter through heavy splatter can be knocked-down. After applying your desired texture pattern let the applied texture material dry for approximately 20 minutes. Using a knock-down knife preferably between 18” and 24” wide (example: Wallboard P/N 33-024Light Weight Knock-Down Knife) and applying very light pressure, flatten the texture material to your desired height. If you create lines in the texture material between passes of the knock-down knife leave them as is until the texture material is completely dried and using 220 grit sand screen or sandpaper gently sand out the lines before painting.

When I attach the air supply to my hopper gun air blows continuously through my hopper gun?
Answer:  If your hopper gun is a Spraying Mantis, Spray Pro or Wal-Pro hopper gun this is normal. Simply install the supplied shut-off (ball) valve at the bottom of handle where the air supply enters the hopper gun. Use the installed shut-off (ball) valve to control air flow through your hopper gun.If your hopper gun is a Texture Pro 200 make sure you have a material orifice and the Orifice Nut installed on the front of the hopper gun prior to attaching your air supply.
