M680 Spray Unit - GRACO, package: 262927

The Graco M680™ mortar piston pump is designed to spray even the most abrasive materials, yet is easy to operate and clean. Applying mortar by hand is very time-consuming. Graco's M680 mortar pump saves time, speeds up work and increases profits by replacing the traditional trowel and float with automatic material spraying and surface finishing.

Advantages:

• Labour cost savings
• Less material waste and better surface quality
• Quick and easy cleaning
• Extremely durable construction
• Ideal for plasterers.

Materials and applications:

• Resin-based mortars
• Bituminous compounds (including two-component 2k)
• Anti-slip paints
• Cement plasters and fireproof insulation
• Materials for changing surface texture
• Shotcrete
• Waterproof insulation
• Polymers with fillers such as glass flakes, silica or sand
• PCC/SPCC mortars
• Facade adhesive
• Low-pressure injections
• Cement-based fillers
