Imer Mortar, Stucco and Fireproofing Gun Kit - 1107005

Imer Mortar, Stucco and Fireproofing Gun Kit - 1107005

The application gun is primarily needed for spraying heavier materials such as fire-proofing, cement based stucco, gypsum based products, cements, etc. This attachment and accessories are compatible with Imer pumps and requires a compressor for use.

Features

• Designed for spraying rough coats of premixed mortar, stucco and fireproofing
• Fits Imer Mighty Small 50, Koine series, Step-Up 120, and Prestige 300 pumps
  
• For use where material needs to be built-up 1/4" or thicker

What our Experts Think

• Core spray system gun for heavy coatings
  The Imer Mortar, Stucco and Fireproofing Gun Kit (Ref. 1107005) is a professional spray application gun set designed for use with IMER pump systems, enabling controlled spraying of thick, cementitious materials.
• Built for heavy, build-up applications
  Specifically engineered for fireproofing, cement-based stucco, gypsum, and mortar, where material is applied in thick layers (typically 1/4" or more).
• Complete job-site ready kit
  Includes a spray gun, multiple nozzle tips, long material hose, air hose, and cleaning tools, giving contractors everything needed for immediate use.
• Designed for IMER pump integration
  Works with systems like the Mighty Small 50 and Koine series pumps, turning them into full spraying setups for façades, walls, and structural coatings.
• Extended reach for large job sites
  Comes with long hose runs (around 50 ft material + 50 ft air), allowing wide coverage without constantly moving the pump unit.
• Built for industrial durability
  Reinforced construction and cam-lock fittings are designed to handle abrasive, high-viscosity materials under continuous pressure.
• Expert insight
  This is not a general-purpose spray gun—it’s part of a system-based finishing platform, where performance depends on correct pairing with IMER pumps and compressors.

Q6: Is it suitable for professional job sites?
A: Yes, it is a contractor-grade system built for continuous, high-volume spraying in commercial and industrial environments.

Q7: Does it require a compressor?
A: Yes, it operates as part of a system and typically requires a compatible air compressor to assist material spraying performance.

Q8: What improves job-site efficiency?
A: Its long hoses, multiple tip sizes, and continuous flow design allow operators to cover large surfaces quickly without frequent stoppages.

Q9: Is it easy to clean after use?
A: Yes, it includes cleaning accessories like sponge balls and nozzle cleaning tools to maintain performance and reduce downtime.

Maintenance Tips

• Flush immediately after every use: Run clean water through the gun, hoses, and nozzle until discharge is clear to prevent mortar, stucco, or fireproofing material from hardening inside.
• Clean spray nozzle & deflectors daily: Remove buildup from 1/2", 3/8", and 9/16" tips to maintain consistent spray pattern and prevent clogging.
• Purge both hoses thoroughly: Flush the material hose and air hose fully after each job to avoid internal blockages and pressure loss.
• Use included cleaning tools: Run sponge balls and nozzle cleaner through the system to keep internal passages clear and extend service life.
• Inspect cam-lock fittings regularly: Ensure tight, leak-free connections on both material and air lines for stable spray performance.
• Prevent material drying inside gun: Never store with residue inside—dried material can permanently damage internal passages.
• Check seals & trigger mechanism: Replace worn O-rings or seals if spray becomes uneven or pressure drops.
• Dry storage only: Store completely clean and dry in a protected case to avoid corrosion and clogging between jobs.
