    Larsens 1550 Levelling Compound

    Larsens 1550 levelling compound offers a professional solution for preparing uneven or rough subfloors. Whether you are installing tiles, vinyl, laminate, or carpet, this flexible compound ensures a smooth and stable base.

    SLC 1550 Flex flows easily across the surface. As a result, it fills minor imperfections and levels the floor with minimal effort. Because it contains flexible properties, it also helps accommodate slight substrate movement.

    For installers who demand consistent results, Larsens 1550 levelling compound delivers both performance and reliability.


    What Is Larsens SLC 1550 Flex?

    Larsens SLC 1550 Flex is a cement-based self levelling compound formulated for internal floor preparation. It creates a flat, smooth surface prior to the installation of decorative floor coverings.

    Unlike standard compounds, this flexible compound improves resistance to cracking. Therefore, it performs well in areas exposed to light movement or thermal variation.

    In addition, it sets quickly. This allows flooring projects to progress without unnecessary delays.


    Key Features of Larsens 1550 Levelling Compound

    Larsens 1550 levelling compound includes several performance-driven benefits:

    Flexible formulation for improved durability

    Excellent flow characteristics

    High compressive strength

    Suitable for thin applications

    Fast setting performance

    Strong adhesion to common substrates

    Because of its smooth flow, installers achieve a professional finish with less manual finishing. Consequently, labour time reduces while installation quality improves.


    Where Can You Use SLC 1550 Flex?

    SLC 1550 Flex suits a wide range of internal environments. It works effectively in both domestic and light commercial settings.

    Suitable Substrates

    Larsens 1550 adheres well to:

    Concrete

    Sand and cement screeds

    Existing tiled floors (with correct preparation)

    Suitable primed substrates

    However, proper priming ensures maximum bond strength. Therefore, always follow recommended preparation guidelines before application.

    Internal Floor Applications

    This floor compound prepares surfaces before installing:

    Ceramic and porcelain tiles

    Luxury vinyl tiles (LVT)

    Sheet vinyl

    Carpet

    Laminate flooring

    Because smoothness directly affects the final finish, using a high-quality self levelling compound remains essential.


    Benefits of Using a Flexible Levelling Compound

    Subfloors often expand and contract slightly over time. As a result, rigid compounds may crack. Larsens 1550 contains flexible properties that help absorb minor movement.

    Additionally, it improves floor longevity. A properly levelled base reduces stress on adhesives and floor coverings. Therefore, the finished surface maintains its appearance for longer.

    Furthermore, smoother substrates reduce installation issues. Installers can lay flooring faster and with greater confidence.
