NIVELOR MAXI TOP

Self-levelling screed for interior application from 2 to 20 mm
In accordance with EN 13813:2003 – class C25F7B2,0A22

Dry calcium-sulphate mixture for levelling of indoor premises

PURPOSE

NIVELOR MAXI TOP is a dry calcium-sulphate mixture for leveling of uneven indoor floors, with a thickness of applying from 2 to 20 mm. It is suitable for applying on different bases, such as concrete, calcium-sulphate, magnesite, or cement-based surfaces. The product characteristics, such as the excellent spreading ability, short drying terms, and high wear-resistance, allow NIVELOR MAXI TOP to be used on floors with integrated heating systems.

PROPERTIES

• Fastness and precision at application

• From 2 to 20 mm

• Short periods of drying

• High wear resistance

• Suitable for floor heating systems

PREPARATION OF THE BASE

The base should be strong, dry, free from oil, dust, sand, and other contaminants or separating layers. The concrete bases should have reached their optimal strength (after 28 days). Before applying NIVELOR MAXI TOP, the base should be primed with TERAZID G-101 (for low-absorbing substrates) or TERAZID G-202 (for high-absorbing substrates). The self-leveling screed should be applied after the primer is completely dry.

CHARACTERISTICS AND TECHNICAL DATA

• Colour: grey

• Base: calcium-sulphate

• Bulk weight: over 1.1 kg/l

• Work temperature: +5˚C to +25˚C

• Time for ‘maturing’: 5-10 minutes

• Open time (for work): 60 minutes

• Maximum thickness of the layer: up to 20 mm

• Ready for walking after: around 5 hours

• Time for final bounding and subsequent operations: 3-5 days

• Compressive strength after 28 days: 26.8 N/mm²

• Flexural strength after 28 days: 7.0 N/mm²

• Abrasion resistance on the 28th day (Böhme method): 35.6 cm³/50 cm²

APPLICATION AND PROCESSING

To fully dissolve the 25 kg of NIVELOR MAXI TOP, around 6 liters of water are required. Into a preliminary prepared container with water, the necessary amount of dry mixture is poured and stirred with a mechanical mixer until a homogeneous mass is achieved. Thus, the stirred mixture is left to stay for about 5-10 minutes, after that it is stirred once again and it is ready for work. It is desirable to prepare as much quantity of NIVELOR MAXI TOP as it could be applied for a period of 60 minutes. Spill the screed over the working area and spread it with a stainless mortarboard till the necessary thickness is achieved. The work starts from the farthest corner of the room, gradually moving towards the door. If necessary, the freshly applied layer is deaerated with a special needle roller. It is advisable to work with special shoes, fitted with spikes.

NIVELOR MAXI TOP characteristics allow walking on the screed 4-5 hours after its application, with a thickness of the layer – 10 mm. Subsequent construction operations should start after 3-5 days, considering the screed humidity and the type of the covering that is going to be applied.

CONSUMPTION

1.4 – 1.6 kg/m² with a thickness of the layer of 1 mm.

TOOLS FOR WORK

• Electrical drill and stirrer

• Steel mortar-board with long handle

• Needle roller

• Shoes with spikes

WEATHER CONDITIONS AT WORK

The minimum twenty-four-hour temperature of the air and the base should not be less than +5˚C, and the maximum – not higher than +25˚C. Lower temperatures could extend processing time, and higher temperatures could reduce it. After application of the self-levelling screed, a temperature of +5˚C to +25˚C should be ensured. Avoid application under direct sunlight or strong air drafts.

FORM OF DELIVERY

Dry mixture in paper bags of 25 kg
