Flow GF

Cement-based, grout and anchoring mortar

Product description

Marlon Flow GF is an easy-flowing, cement and polymer-based ready mixed dry mortar product to which you only need to add water. Marlon Flow GF develops strength quickly and with its admixture has an extraordinary peel adhesion to the substrate. In hardened form, it is tension-free, corrosion-inhibiting and chloride resistant. Frost and weather resistant.

  • Develops strength quickly
  • Easy-flowing
  • Polymer-modified
  • Increased adhesion
  • Tension-free
  • Expands in the plastic phase
  • Only requires added water
Areas of application

Marlon Flow GF is easy-flowing and is therefore well suited to the vertical cementing of metal items such as bolts, reinforcement rods, threaded rods etc. in concrete, brick and granite. The product can also be used for grouting and repair jobs.


In order to ensure the best possible adhe- sion to the surface/object, it must be clean of dust, oil, grease, cement slurry and other loose particles. Highly absorbent surfaces must be moistened to create a uniform, matt surface with low absorbency.


Marlon Flow GF is mixed with a low-speed drill with a two-blade mixing impeller attached. Cold mixing water is poured into a bowl/pail, after which the powder is added while continuing to stir the mixture. Mix thoroughly for at least 3 minutes until a lumpfree, easy-flowing consistency is achieved.


The ready-mixed mortar is used immediately after mixing. Marlon Flow GF should be used under normal circumstances at 20ºC within approximately 20 minutes. Keep stirring the mass throughout the entire cementing process. Lower temperatures extend and higher temperatures shorten the processing and hardening times.


Open surfaces should be protected against drying out too quickly where there are draughts, high temperatures and when exposed to sunlight with Marlon Curing B75. During the winter months, protect the mortar against extreme night frost, strong winds etc. (using winter mats, if necessary) during the first 24 hours of curing.


Casting should not take place in temperatures lower than +5°C. The product cannot tolerate frost during the curing and setting period.


Tools are cleaned with water immediately after use. Hardened Flow GF can only be removed mechanically.


Marlon Flow GF is subject to internal controls in accordance with Marlon’s quality assurance system. Subsequent measuring and mixing at the site of application is not included in the quality control.
