Professional Mixing Paddles for Concrete, GFRC, UHPC, Mortars & Construction Materials

The mixing paddle is one of the most important factors in achieving a smooth, lump-free, and consistent mix. Different materials require different mixing actions, and using the proper paddle can dramatically improve material flow, reduce air entrainment, and increase overall mixing efficiency.

Fishstone offers professional-grade Collomix mixing paddles designed specifically for high-performance concrete, GFRC, UHPC, mortars, overlays, self-levelers, epoxy systems, and other demanding construction materials.

Manufactured in Germany from high-quality steel, Collomix paddles are engineered for durability, superior mixing action, and long-term professional use.

Available Paddle Styles

MK Mixing Paddle

Designed for Heavy & Highly Viscous Materials

The Collomix MK paddle is specifically engineered for dense, heavy materials such as concrete, mortars, plaster, quartz-filled epoxy systems, and high-performance cementitious mixes. Its aggressive three-helix design pulls material from the bottom upward while powering through thick mixes with ease.

Best Applications

• Concrete
• GFRC backer mixes
• UHPC bag mixes
• Mortars
• Screeds
• Plaster
• Quartz-filled epoxy mortars
• Cementitious overlays

Features

• Powerful bottom-to-top mixing action
• Three-helix design for aggressive material movement
• Excellent for heavy and dense materials
• Reduces dry pockets and unmixed material
• Protective ring helps prevent bucket damage
• Heavy-duty powder-coated steel construction

Best For

Professional mixing of heavy cementitious and high-viscosity materials where maximum mixing power is required.

KR Mixing Paddle

High-Shear Paddle for Creamy & Sticky Materials

The Collomix KR paddle is designed for creamy, sticky, and flowable materials where smooth homogenization and reduced air entrainment are critical. The unique vertical blade geometry creates high shear forces that quickly eliminate lumps while maintaining smooth material flow.

Best Applications

• Thinset mortar
• Tile adhesives
• Grouts
• Fillers
• Epoxy grouts
• Self-leveling compounds
• Resin systems
• Smooth cementitious materials

Features

• High-shear mixing action
• Excellent lump reduction
• Low air entrainment
• Parallel mixing action for sticky materials
• Easy-to-clean design
• Protective ring helps prevent bucket wear
• Excellent for smooth, creamy materials

Best For

Mixing smooth, creamy, or sticky materials where consistency and reduced trapped air are important.

MKD Dual Mixing Paddle

Counter-Rotating Forced-Action Mixing System

The Collomix MKD paddle system utilizes dual counter-rotating paddles that force material through the mixing zone for extremely fast and thorough mixing. This forced-action mixing design delivers exceptional results with dense, difficult, or high-performance materials while significantly reducing mixer torque reaction and operator fatigue.

Best Applications

• UHPC
• ECC mixes
• Concrete
• Mortars
• Quartz-filled epoxy systems
• Dense cementitious materials
• Structural repair materials
• Heavy construction mixes

Features

• Dual counter-rotating paddles
• Forced-action mixing technology
• Extremely fast material blending
• Up to 50% faster mixing performance
• Excellent for difficult or dense materials
• Reduced mixer twisting force
• Superior fiber and aggregate distribution
• Compatible with Collomix Xo Duo mixers

Best For

Professionals mixing heavy, fiber-rich, or difficult materials that require maximum mixing efficiency and consistency.

Why the Correct Mixing Paddle Matters

Using the proper mixing paddle can significantly improve:

• Surface finish quality
• Fiber dispersion
• Pigment consistency
• Material flowability
• Mixing speed
• Strength development
• Reduction of trapped air
• Overall concrete performance

The correct paddle not only improves mixing results but also reduces strain on both the mixer and operator.

Ideal Applications

Collomix mixing paddles are ideal for:

• GFRC concrete countertops
• UHPC and ECC mixes
• Decorative concrete
• Concrete repair mortars
• Cementitious overlays
• Self-leveling underlayments
• Resin systems
• Artisan concrete fabrication
• Construction materials

These paddles pair exceptionally well with:

• Collomix XQ Series Mixers
• Fishstone HP50
• ULTRACAST 360
• Super-SIX Admix
• KongKrete Polymer
• GFRC and UHPC systems
