Lanko 173 FLOOR LEVELLER

Lanko 173 Floor Leveller is a cement based levelling compound for use over concrete sub-floors prior to the application of floor coverings. Lanko 173 Floor Leveller is ideal for repairing small holes, static cracks and depressions and is suitable for use both indoors and outdoors. It requires the addition of only potable water to achieve a highly fluid consistency producing a smooth, level, and hard surface. Lanko 173 Floor Leveller can be applied in multiple layers with each layer being no more than 25mm thick or can be economically extended with a graded aggregate to fill greater depths.

USES:

Lanko 173 Floor Leveller is used to repair dry areas of structurally sound concrete subfloors. Lanko 173 Floor Leveller is used as a subfloor underlayment prior to installation of carpet, tiles or other floor covering systems. It is compatible with commonly used adhesives and normally can receive floor coverings within hours of installation – please see Test Data below. Lanko 173 Floor Leveller is not a wearing surface and must be protected with a compatible topping, floor covering or coating. Lanko 173 is not suitable for use in permanently wet areas of immersion.

SURFACE PREPARATION:

• Surfaces, must be dry, structurally sound, clean, free of dust, dirt, wax, oil, grease, asphalt, mastic, latex compounds, adhesives, paint, gypsum based products, and other contaminants.

• All concrete sub-floors must be fully cured and dry, in accordance with AS1884-1985 (maximum moisture content 5.5% or 70% humidity). They must be free of laitance, loose or deteriorated concrete, curing or form release agents, other contaminants and have a wood float finish. For sub-floors with a high moisture content or subject to rising damp, apply Lanko 531 Epoxy Moisture Barrier. Refer to datasheet for specific instructions.

• Non-porous surfaces, such as power trowelled or steel floated concrete, must be primed with Lanko 531 Epoxy Moisture Barrier or Davco Ultrabond. Alternatively, they can be acid etched or mechanically abraded.

• Deeply contaminated substrates must be abraded to a clean, sound surface or some substrates can be prepared with the use of Davco Ultrabond – a bonding coat for contaminated surfaces. Contact the Lanko Technical Advisory Line for further details on the suitability of Ultrabond over different contaminants.

• Patch large cracks and holes with a suitable Concrete Repair Mortar.

• Any construction joints in the underlying sub-floor should be carried through the Lanko 173

Floor Leveller, to avoid cracking.

SURFACE PRIMING:

• Priming is crucial prior to the application of Lanko 173 Floor Leveller. It is designed to improve adhesion and greatly reduce pinholing in the finished floor.

• Porous concrete surfaces must be primed with Lanko 124 Ultraprime. Use Lanko 124 Ultraprime directly from the container – do not dilute.

• Under hot, windy conditions (Temp above 30oC), it is essential to wet down any concrete slabs with clean water prior to priming, so that the primer does not flash dry. After wetting down the floor, do not allow the water to pool or pond on the surface. The substrate should appear matt, with no signs of glistening water evident prior to application of the primer.

• Test areas

Test areas should be performed in all cases, to assure the suitability of the product for the intended use. This should include the floor finishing/covering.

COVERAGE:

One 20kg bag of Lanko 173 Floor Leveller will cover approximately 12m2 at 1mm thickness.

CLEAN-UP INSTRUCTIONS:

• Clean mixing and application equipment with water immediately following use.

• Remove splatter or spills with water before material sets.

• Lanko 173 Floor Leveller contains cementitious materials,

and if allowed to dry, removal becomes extremely difficult.

PACKAGING:

20kg polylined bags.

FLOOR COVERINGS:

As a general guide, the surface finish of Lanko 173 Floor Leveller is not dissimilar to concrete. Any adhesives used to bond subsequent floor coverings that are compatible with concrete will be compatible with Lanko 173 Floor Leveller. Strictly follow the floor covering adhesive manufacturer’s instructions.

SHELF LIFE / STORAGE:

• Storage: must be stored in a cool, dry elevated place and protected from high humidity.

• Shelf Life: Up to 6 months in unopened bags, if stored as specified above

SAFETY:

• Being cement based, Lanko 173 Floor Leveller is alkali in nature, which can cause dermatitis. Thus, when using Lanko 173 Floor Leveller, it is recommended that applicators wear PVC or similar gloves and safety goggles.
