Sikafloor 440 Level is a fibre-reinforced cement-based self-levelling compound designed specifically for challenging flooring applications, including underfloor heating and wooden substrates, producing a strong yet flexible finish suitable for various floor coverings or as a standalone trafficable finish.

Who This Product Is For

This compound is designed for flooring professionals and serious renovation contractors working on challenging floor installations. It suits those handling projects where substrate movement or underfloor heating systems require flexible, crack-resistant levelling solutions.

Key Features

• Heat Resistant Formula: Specifically suitable for underfloor heating, minimising the risk of cracks or shrinkage
• Fibre Reinforcement: Adds flexibility and strength, accommodating slight movement in wooden or complex subfloors
• Rapid Drying: Walkable after 3 hours; ready for floor coverings within 4 to 5 hours
• Internal and External Application: Reliable for indoor use or external environments requiring levelling prior to floor installation
• Easy Application: Excellent flow properties make spreading and levelling straightforward without requiring additional latex additives

Practical Applications

The Sikafloor 440 compound is ideal for levelling uneven floors, embedding underfloor heating systems, resurfacing wooden substrates, smoothing existing ceramic tiles, and providing a finished trafficable surface in commercial or residential areas. Its robust performance is beneficial for both internal renovations and external resurfacing.

• Underfloor Heating Installations: Provides smooth coverage and prevents heat-induced cracks
• Wooden Floor Levelling: Creates a flexible surface, reducing the risk of floor movement and cracking
• Concrete Floor Repairs: Quickly corrects uneven surfaces, allowing swift installation of subsequent finishes
• Ceramic Tile Overlay: Efficiently smooths and levels tiled surfaces without removing existing tiles
• Outdoor Levelling: Suitable for patios or external structures requiring a stable, smooth finish

How This Fits Into a Typical Job

This compound is used during the substrate preparation phase, after surface cleaning but before floor covering installation. It creates the level base layer that accommodates substrate movement, particularly important for underfloor heating systems or wooden floors where thermal expansion and contraction occur.

How to Use

1. Surface Preparation:
   • Make sure surfaces are clean, dry and free from grease, dust or loose debris
2. Mixing:
   • Combine one 20kg bag with 4.4 litres of clean water, mixing until smooth and lump-free. Use a 25 litre mixing bucket for easy preparation and pouring
3. Application:
   • Pour evenly across the surface, spreading with a trowel or smoothing tool to achieve uniform thickness. A soft-grip trowel helps distribute the compound evenly
4. Layer Thickness:
   • Apply between 2mm and 30mm per layer; for thicker layers up to 60mm, use an alternative specialised product
5. Drying:
   • Allow 3 hours of drying time before foot traffic; wait 4 to 5 hours before laying floor coverings
6. Final Check:
   • Inspect the surface for levelness and smoothness before proceeding with further installations
