The Best in the World Just Got Better

Drywall texture is a go-to finish for both ceilings and walls. Texture helps conceal minor imperfections and stands up better to the bumps and scuffs of everyday life, from kids and pets to normal wear.

The tool of choice is a hopper gun, which uses a hopper to hold material and compressed air to deliver an even spray. MARSHALLTOWN offers several hopper guns, and now, there’s a new and improved one in the lineup.

The WAL-BOARD TOOLS TEXTURE-PRO® 500 is the hopper gun designed for professionals. With several innovative features, it provides versatility, durability, and increased productivity on the job.

1. Versatile 

The TEXTURE-PRO® 500 features an orifice plate with six versatile spray options, allowing for multiple application scenarios without the need to purchase additional nozzles. This is especially helpful when working in older homes with several texture types throughout. Having the six patterns on one plate adds convenience and efficiency. In addition to acoustics, drywall mud, and concrete overlays, this hopper gun is also ideal for spraying silica sand with primer, waterproofing, and most other gravity fed materials.

2. Increased Productivity

Three of the orifice openings feature a WideTex™ spray pattern, providing up to 30% more coverage and ultimately, reducing work time. The larger 1-3/4-gal capacity hopper minimizes refills, while the hopper lid keeps material fresh, which is especially beneficial during breaks or lunchtime.

The TEXTURE-PRO® 500 also has a reversible hopper for spraying both floors and ceilings with less mess. Its patented trigger controlled airflow technology delivers more consistent texture and its handy air adjustment valve allows for flow control at the gun instead of the pump.

3. Durable

Built tough and built right, the TEXTURE-PRO® 500 has a solid, heavy-duty cast aluminum spray gun body, an ergonomic rubber grip and trigger, and a high-quality hopper with a built-in handle on the top for optimal control.

Every feature has been purposely designed and built to solve real challenges on the job, making it no surprise that the American-made WAL-BOARD TOOLS TEXTURE-PRO® 500 easily outperforms the competition and sets a new standard for hopper guns.

 FAQs

Q: What is the WAL-BOARD TOOLS TEXTURE-PRO® 500 Hopper Gun?

A: The TEXTURE-PRO® 500 is a hopper gun designed to spray wall and ceiling texture materials, including fog, orange peel, knockdown, and acoustic finishes. It connects to an air compressor and uses adjustable orifices, air pressure, and trigger settings to control texture pattern and material flow.

Q: What textures can I spray with the TEXTURE-PRO® 500?

A: The TEXTURE-PRO® 500 can spray Fog, Orange Peel, Knockdown, and Acoustic textures. Texture pattern is controlled by material thickness, orifice selection, air pressure, trigger distance, and flow control settings.

Q: What size air compressor is required for the TEXTURE-PRO® 500?

A: The TEXTURE-PRO® 500 requires a compressor with a minimum rating of 2.4 CFM at 90 psi or 5.3 CFM at 40 psi. Insufficient compressor volume (CFM) will prevent proper atomization of the material.

Q: What air pressure settings should I use?

A:  Lower atomizing pressure produces heavier texture patterns. Higher pressure produces finer patterns. Recommended compressor air pressure settings are:

• Fog: 50 psi
• Orange Peel: 50 psi
• Knockdown: 50 psi
• Acoustic: 30 psi

Q: How do I thin joint compound for the TEXTURE-PRO® 500?

A:  When using all-purpose joint compound or lightweight topping compound, thin by adding approximately 1/3 gallon of water for each gallon of compound. After mixing, the material should have the consistency of thick paint or thin pancake batter.

Q: Which nozzle (material orifice) should I use for each texture?

A: Selecting the proper orifice is critical to achieving the desired pattern.

• Fog: Nozzle #1 (WideTex™)
• Orange Peel: Nozzles #2 (Round) or #3 (WideTex™)
• Knockdown: Nozzles #4 (Round) or #5 (WideTex™)
• Acoustic: Nozzles #5 (WideTex™) or #6 (Round)

Q: How far should I stand from the surface when spraying?

A: For walls (vertical surfaces), stand 3 to 4 feet from the surface. For ceilings (horizontal surfaces), position yourself approximately 18 inches below the ceiling and hold the hopper at a 30–50° upward angle (manual setup section specifies 45° orientation; troubleshooting specifies 30–50°).

Q: How do I adjust material flow and trigger pull?

A: Trigger pull distance is adjusted using the Adjustable Stop (knurled knob) on the back of the gun. Turning clockwise shortens trigger pull distance; turning counterclockwise increases it. The Flow Control Valve allows small airflow adjustments at the gun without returning to the compressor.

Q: How full should I fill the hopper?

A: Fill the hopper 2/3 to 3/4 full with texture material for proper operation and control.

Q: How do I properly clean and maintain the TEXTURE-PRO® 500?

A: (1) Flush all remaining texture material with water. Mild soap may be used if needed. (2) Turn the gun upside down and place 8–10 drops of light household oil (such as 3-in-1®) into the Quick Disconnect. (3) Reattach the air hose and pull the trigger for 10–15 seconds to lubricate internal O-rings. (4) Disconnect the air hose and store the hopper gun in a dry environment.

Always wear appropriate safety equipment when operating the TEXTURE-PRO® 500.
