Product Coverage and Mixing Instructions

To determine the amount of self-levelling compound needed, multiply the area in square metres by the desired depth in millimetres and then by 1.4. This calculation ensures accurate coverage and avoids wastage.

• Approximate Coverage per 25kg Bag

• 6 sqm at 3mm
• 4.5 sqm at 4mm
• 3.6 sqm at 5mm
• 3 sqm at 6mm
• 2.6 sqm at 7mm
• 2.3 sqm at 8mm
• 2 sqm at 9mm
• 1.8 sqm at 10mm (Typical for underfloor heating)

• Mixing Instructions

• Pour a 25kg bag of Ultraplan 3240 into 4.25-4.5 litres of clean water.
• Mix with a low-speed electric mixer until homogeneous and lump-free.
• Allow the mixture to rest for 2-3 minutes, then re-stir before use.
• Use the mixed product within 20 minutes (at 23°C).

Preparation and Application

Proper preparation of the substrate is crucial for optimal results. Ensure the substrate is solid, free of dust, loose particles, paint, oil, gypsum residues, or other contaminants that could compromise the bond. Specific preparation steps include:

• Cleaning and Priming

For timber substrates, ensure they are clean and solidly fixed, sealing open joints with Planiprep Fix. Cementitious surfaces not sufficiently compacted should be removed or consolidated with Prosfas or Primer EP. Cracks should be repaired with Eporip. Prime the substrate with Eco Prim Grip Plus or Eco Prim T Plus before applying Ultraplan 3240.

• Application Method

Apply Ultraplan 3240 in a single coat from 3mm to 40mm thickness. Use a spiked roller to minimise aeration and achieve a smooth finish. The self-levelling properties of Ultraplan 3240 ensure a surface ready to accept various floor coverings.

Sizes Available

Ultraplan 3240 is available in 25kg bags and pallets of 40 x 25kg bags, providing flexibility for projects of all sizes.
