MAPEI Ultraplan Maxi Self-Levelling Compound 3-40mm 25kg

MAPEI Ultraplan Maxi 25 kg – very fast-setting, self-levelling floor smoothing compound 3–40 mm

Ultraplan Maxi is a very fast-setting, self-levelling floor smoothing compound for interior use in layer thicknesses from 3 to 40 mm per application. It levels out unevenness on new and existing substrates and prepares them for almost all types of floor coverings – even in areas subject to high levels of traffic.

Ultraplan Maxi is suitable for use with underfloor heating, is part of the MAPELIGHT SYSTEM, and is very low in emissions (EMICODE EC1 Plus).

Package contents: 25 kg bag, individually or as a pallet of 40 bags. Fine grey powder.

Advantages of Ultraplan Maxi

• Walkable after approx. 3 hours – ready for ceramics after approx. 3 hours, ready for resilient and wood coverings after approx. 12 hours
• Suitable for underfloor heating
• Very low VOC emissions (EMICODE EC1 Plus)
• Can be applied with a smoothing trowel, squeegee, or pump

Typical application areas

• Leveling of concrete, cementitious and anhydrite screeds before laying floor coverings

Consumption

Consumption is approx. 1.7 kg/m² per mm of layer thickness. For 5 mm, you need approx. 8.5 kg/m² – one 25 kg bag is therefore sufficient for approx. 3 m², a pallet (40 bags) for approx. 118 m².

Application of Ultraplan Maxi

1. Preparing the substrate

The substrate must be load-bearing, dry, and free of dust, loose particles, oil, and release agents. Prime absorbent substrates, e.g., with MAPEI Eco Prim T Plus; prime smooth and non-absorbent substrates with MAPEI Eco Prim Grip Plus. Install edge insulation strips such as MAPEI Mapestrip Perimeter.

2. Mixing

Pour 4.5–4.75 l of clean water into a mixing bucket, add the bag contents while stirring continuously, and mix with a low-speed mixer until lump-free.

3. Pouring and spreading

Pour the mixture and spread it with a smoothing trowel or squeegee within the pot life (30–40 minutes). Larger areas can be pumped.

4. De-aeration

Roll over the fresh surface with a de-aeration roller (spiked roller), using spiked shoes.

5. Covering

Walkable after approx. 3 hours. Ready for ceramics after approx. 3 hours, ready for resilient floor coverings and wooden floors after approx. 12 hours – up to 1–3 days depending on layer thickness and room climate.
