Sika SikaFlow 648 Low Dust Epoxy Grout, 1.73 cf Unit
SikaFlow 648 (formerly MasterFlow 648) is a three-component, high-strength, high-flow epoxy precision grout designed for critical equipment alignment and load transfer. The low-dust aggregate formulation improves worker comfort and jobsite cleanliness while delivering high early strength, excellent chemical resistance, low creep, and full baseplate contact. The standard 4-bag unit yields approximately 1.7–1.73 cubic feet and can be adjusted to a higher-flow 3-bag mix when needed.
Key Features
- Low-dust aggregate for improved handling and safety.
- High early and ultimate compressive strength (up to 16,000 psi post-cured).
- Excellent flow for pours from ½ in to 6 in.
- Very low shrinkage for high effective bearing area.
- Low creep under elevated temperature and sustained load.
- Variable fill ratio (3-bag or 4-bag) for flow control.
- Soap-and-water clean-up.
Applications
- Precision alignment of compressors, generators, pumps, and motors.
- Crane rail and sole plate grouting.
- Wind turbine tower bases.
- Rolling mills, stamping presses, and high-torque machinery.
- Equipment subject to vibration and dynamic loads.

Frequently Asked Questions
What does “Low Dust” mean for this product?
The aggregate is specially formulated to release significantly less airborne dust during mixing and handling, improving jobsite air quality and worker comfort.
Can the fill ratio be adjusted?
Yes. The standard 4-bag mix provides higher strength; a 3-bag mix increases flow for tighter clearances or longer distances.
What is the maximum pour thickness?
Up to 6 inches (150 mm) in a single lift under normal conditions.
How long is the working time?
Approximately 90–120 minutes at 70°F, depending on temperature and mix ratio.
Is soap-and-water clean-up possible?
Yes. Tools and equipment can be cleaned with soap and water before the material cures.
