Marlon Floor HG25 (Danish name: Marlon Flydespartel HG25) is a factory-produced, self-levelling dry mortar made from fast hardening cement, mineral additives, polymer and oven-dried fine-grained silica sand. The product is ready for use after clean water is added and the mixture is mixed effectively.
- Can be applicated in thicknesses up to 80 mm
- Pumpable and self-levelling flooring
- Volume-stable, laying of large, jointfree areas
- Fast drying
- Just add water
Marlon Floor HG25 is a universal self-levelling liquid floor screed that is typically used as underlayment for othere self-leveling toplayers (as Marlon Floor H30 or H35) or carpets, clinkers, woodfloors, linoleum, vinyl and tiles. Marlon Floor HG25 may not be used outdoors and must, in areas where there is continuous exposure to water, be covered in an MK-certified (Danish material and constructions certification) waterproofing membrane. For nonporous coatings, such as linoleum, vinyl, membranes and for jointfree coatings, it is important that Marlon Floor HG25 dry sufficiently before laying the non-porous coating. Typical time for the dryout, depends on the layer thickness, humidity and temperature (for wooden flooring, always follow the manufacturer’s instructions).
The surface must be well-suited, firm and free of any loose particles, dust or other impurities that could prevent sufficient adhesion to the surface, which should have a tensile strength of min. 1 MPa on the surface. The cleaned surface is primed 1-2 times with Marlon Primer FL, until the surface is saturated, before the work is started. Avoid the formation of primer puddles (see separate specification sheet for Marlon Primer FL).
Manual mixing is done with a slow-rotating drill with a two-bladed propeller mixer attached. Marlon recommends first pouring ¾ of the water in a bucket/mixing tub. Next, add the dry powder mix and mix thoroughly while gradually adding the remaining water. Mix well until the mixture is free of lumps and very fluid. For large projects, it is a good idea to use a mortar pump.
Marlon Floor HG25 is poured or pumped out though hoses on the floor surface. You start where the thickest layer is to be laid. The thickness is typically between 10 and 80 mm, which can be applied in a single work process. A plunger stick, spiked roller, spacer knife or other material/tools can be used where suitable. In normal conditions at approx. +20°C Marlon Floor HG25 can be walked on after about 1-2 hours setting and tolerates heavier traffic after about 1-3 days. The opening time is approx. 15-20 min.
Newly laid Marlon Floor HG25 must be protected from rapid drying from draughts, high room temperatures, sun rays and the like.
Not for use outdoors. Does not tolerate frost during pouring, hardening and setting. Building site conditions such as cooled surroundings in the construction and/or cooled products will diminish the liquidity and the product’s curing and drying properties. Likewise, high temperatures can also affect the product’s properties by shortening the working time and by speeding up drying.
Clean equipment, machinery and tools with water immediately after use.
Marlon Floor HG25 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.
