Sikafloor® 122 Level Universal - Fibre-Reinforced Self-Levelling Compound

Multi-Purpose, Self-Levelling Floor Compound for Internal Smoothing Applications. Sikafloor®-122 Level Universal is a one-part, cement-based, self-levelling compound designed to smooth and level uneven internal rigid floors prior to the application of final floor coverings. Suitable for a wide range of substrates including concrete, sand/cement screeds, and dense tile surfaces, it provides a protein-free, low-shrinkage solution ideal for both commercial and domestic environments.. Key Features & Benefits. Self-Smoothing: Highly fluid formulation allows for easy manual or pumped application.. Fast Setting: Walkable in 2–4 hours and ready to overlay in approximately 8 hours at 20°C.. Protein & Formaldehyde Free: Ideal for sensitive areas including hospitals and food preparation zones.. Low Shrinkage: Reduces the risk of cracking and ensures a strong, durable base layer.. Versatile Substrate Compatibility: Suitable for application over concrete, screeds (not anhydrite), ceramic tiles, terrazzo, and quarry tiles.. Underfloor Heating Compatible: Can be applied beneath heating cables or pipes (not for embedding).. Product Details. Form: Grey powder (cement and aggregate based). Packaging: 20 kg bag. Application Thickness: Featheredge to 6 mm per layer. Coverage: Approx. 4 m² at 3 mm thickness per 20 kg bag. Compressive Strength: >20 N/mm² (28 days). Flexural Strength: >5 N/mm² (28 days). Fire Classification: A1fl. EN Classification: EN 13813 CT-C20-F5. Application Instructions. Surface Preparation: Substrates must be sound, dry, clean, and free of contaminants or laitance. Prime porous substrates with SikaBond® PVA+ diluted 1:4. Non-porous substrates should be mechanically roughened and coated with undiluted PVA.. Mixing: Add 3.4–3.5 L of clean water per 20 kg of powder. Always add powder to water. Mix with a spiral paddle for a minimum of 3 minutes to achieve a smooth, lump-free consistency.. Application: Pour mixed material onto the floor and spread evenly with a steel trowel. Apply within 20 minutes. Use a spiked roller to remove air and improve finish.. Curing: Protect from moisture and draughts for at least 24 hours. Avoid premature drying in warm conditions by misting the surface if needed.. Limitations. Not suitable as a final wearing surface.. Do not apply over floating floors, vinyl, insulation boards, anhydrite screeds, or asphalt substrates.. Do not exceed recommended thickness (6 mm per coat).. For interior use only; not suitable for exterior applications or rising damp conditions.. Do not use as a damp-proof membrane (DPM).. Health & Safety. Always wear appropriate PPE including gloves, goggles, and a dust mask during mixing and application. Refer to the Safety Data Sheet (SDS) for full guidance.
