Product description
Marlon Concrete Repair FT is a fibre-reinforced, cement-based premixed dry mortar product, consisting of Portland cement, Pozzolana, polymers, plasticisation and adhesive-enhancing additives, plus oven-dried quartz sand with a controlled grain curve. Marlon Concrete Repair FT is mixed to a dense mortar with low shrinkage, the composition of which gives optimum adhesion and ease of use. It is ideal for concrete repairs to horizontal and vertical surfaces, including overhangs, in aggressive environments. Marlon Concrete Repair FT fulfils the material requirements for environment class E, DS/EN 206 DK NA:2020, contains no corrosive elements and is water and wind resistant.
- Mortar to horizontal and vertical repair
- Fibre-reinforced
- R4 concrete
- Well suited for repairs from 2 mm up to 50 mm
- Just add water
Marlon Concrete Repair FT is used for the repair of horizontal, vertical and overhanging surfaces exposed to aggressive environments - e.g. on bridges, beams, decking and columns - and for the repair and renovation of balconies, facades etc. Places where the surface is concrete.
Clean the surface to be repaired of loose materials, dust, cement crust, oil, rendering or other contaminants which can prevent adhesion. The mortar can be applied to firm, dry and damp surfaces. Smooth surfaces must be keyed to ensure sufficient contact for the mortar. We recommend applying a suitable cement wash to ensure maximum adhesion.
Add approx. 0.14 litres clean cold water per 1 kg dry product (2.9 litres per 20 kg). Mix thoroughly in a suitable mixer for min. 5 mins. An electric drill with a blender bit can be used for small quantities. Mix to a good smooth consistence, allow to stand for 5 to 7 mins. before mixing again. Recommended layer thickness: between 2 and 50 mm. Apply the mixed mortar to the damaged area using a trowel. Spread thinly over the edge of the damaged area for a smooth finish. Apply a patterned finish using felt, rendering or a steel grille. Lower temperatures will extend and higher temperatures shorten opening and curing time. Under normal conditions at +20ºC, the mix is pliable for approx. 30 mins. We recommend applying a small amount of the mix as a test in the event of doubt.
Do not expose newly-laid concrete to pressure, and protect against rapid drying-out caused bydraughts, high room temperature, sunlight etc. as soon as possible after application.
Do not apply Concrete Repair FT at temperatures below +5ºC, or over +30ºC. Cannot tolerate frost during the curing and binding period.
Clean equipment, machinery and tools with water immediately after use. Hardened Expanded Concrete can only be removed mechanically
Marlon Concrete Repair FT is subject to internal inspection according to Marlon’s quality assurance system. Subsequent measuring and mixing at the site of application is not included in quality control.
