Grout EKF 804LM Winter
Expanding liquid mortar for grouting jobs
Marlon Grout EKF 804LM, Winter is a factory-produced expanding liquid mortar made of Portland cement, mineral adhesives, additives, latex polymer and oven-dried silica sand with a controlled grain curve. The product’s high content of latex polymer gives the mortar particularly good flow and adhesive properties. Marlon Grout EKF 804LM, Winter requires only the addition of water and, when mixed, is a very fluid pumpable mortar. For large projects, the mortar can be applied with the help of a suitable screw or piston pump. The product satisfies the material requirements for the extra aggressive environmental class E (see DS/EN 206 DK NA:2020).
- Pumpable expanding liquid mortar
- Shrinkage-compensated, latex-modified
- High strength
- Can be used down to -5°C
- Just add water
Marlon Grout EKF 804LM, Winter is used, e.g. for grouting of machine foundations and embedment work. Marlon Grout EKF 804LM, Winter is also well suited for jointing underneath and between prefabricated concrete elements, for pouring of corrugated pipes in concrete element constructions or for projects that are difficult to access with traditional methods.
To ensure the best possible adhesion for existing concrete, the surface must be cleaned of any cement slurry, oil, grease or other loose impurities through, e.g. chipping, sandblasting or high-pressure cleaning, and reinforcing iron must be cleaned of rust and chlorides. The cleaned surface must be watered, to produce a uniform, dull and slightly absorbent surface. Metal surfaces must be cleaned of any grease, rust etc.
Marlon Grout EFK 804LM, winter is mixed with clean water (approx. 14 weight percentage). The dry powder and approx. 80% of the water for mixing is poured into a suitable agitator mixer. During effective mixing, the remaining water is added until you achieve a very fluid, lump-free mortar. Manual mixing can be done in a tub/bucket using a drill with a two-bladed propeller mixer. When mixing with a drill, first pour the water into the bucket, and then add the powder while mixing. Mix until you achieve a very liquid consistency. The mixing time should be at least 3 min. On mixing and application, check that the compound does not separate.
Marlon Grout EFK 804LM, Winter can generally be applied in thicknesses from approx. 10 mm up to 100 mm. For greater layer thicknesses, an aggregate of larger stone fractions of 20-25% can be added. Depending on the nature of the surface, large variations in the surface can result in contraction cracks. To achieve optimal benefit from the expansion, blend only the amount of mortar that can be used within approx. 20 min at +20°C. Higher temperatures will shorten, and higher temperatures will lengthen both the processing and hardening times.
The newly poured mortar surface must not be exposed to loads and must be protected as quickly as possible after pouring against rapid drying from draughts, high room temperature, sun rays, etc. Use of sealed plastic or a suitable curing membrane is recommended.
Marlon Grout EKF 804LM, Winter should not be used at temperatures under -5°C or over +5°C.
Clean tools with water immediately after use. Hardened Grout EKF 804LM, Winter can only be removed mechanically.
Marlon Grout EKF 804LM, Winter 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.
