KRONOS AUTOLIV: fiber-reinforced leveling compound for interior floors

An integrated leveling solution for lightweight flooring systems

With KRONOS AUTOLIV, EDILTECO® France completes its range of lightweight screeds and mortars by incorporating a product dedicated to surface preparation.

This fiber-reinforced self-leveling compound is part of a logic of technical continuityenabling companies to work with compatible systems, from raw support to finishing.

The plaster is designed to receive different coatings:

• glued tiles,

• parquet flooring (glued or floating),

• flexible or rigid plastic coatings,

• textile.

It is intended for listed premises P2 and P3, according to land use requirements.

What are the technical performance characteristics of this fiber-reinforced leveling compound?

KRONOS AUTOLIV is classified CT-C30-F6 according to standard EN 13813, reference for screed mortars.

This classification reflects:

• another compressive strength of 30 MPa,

• another flexural strength of 6 MPa.

These values ​​position the product at a performance level suitable for areas with moderate to high stress.

Its application thickness varies from:

• 1 to 10 mm in P2 premises,

• 3 to 10 mm in P3 premises.

The product is specifically compatible with media based on lightweight screeds and mortars ≥ 300 kg/m³, a key point to guarantee the mechanical consistency of the structure.

However, one technical limitation must be highlighted: this type of coating is intended to be covered and cannot constitute a visible finish.

Optimized intervention times on site

One of the major challenges in soil preparation remains the return-to-service timeKRONOS AUTOLIV offers the following delivery times:

• Pedestrian traffic: approximately 4 hours,

• tile or textile installation: 24 hours,

• plastic coatings: 48 hours,

• glued parquet flooring: 96 hours.

These timeframes allow operations to be linked together and reduce downtime of surfaces, an advantage on construction sites with tight schedules.

For installation companies, this translates into a improved management of intervention phases and an optimization of overall lead times.

Implementation: what are the technical requirements?

As with any leveling compound, performance depends directly on the application conditions.

Surface preparation and primer application

The supports must comply with DTU and technical specifications in forceThe application of a bonding primer, in this case of the latex type (Edilstik®), is essential to guarantee adhesion.

Application Methodology

Implementation follows a specific process:

• homogeneous mixture without lumps,

• resting time for the batch (2 to 3 minutes),

• application in a single pass with a stainless steel trowel,

• A bubble-removing roller can be used.

The professional technique is crucial: drawing "from scratch" to fill the pores, then adjusting the thickness to obtain a flat surface.

Construction site conditions to be controlled

The application must meet strict conditions:

• temperature between +5 °C and +30 °C,

• support that is not frozen and not damp

• absence of drafts or direct sunlight.

These parameters directly influence the material's adhesion and the final surface quality.

"Careful application is essential for the performance of the leveling compound."

A response to the challenges of flatness and compatibility

Subfloor preparation is a key step in ensuring the durability of floor coverings. Unevenness can lead to:

• aesthetic problems,

• detachments,

• premature wear.

By offering a leveling compound compatible with its own systems, EDILTECO® France seeks to limit the risks of incompatibility between materials, a point often identified by design offices and project managers.

Concrete example of application

On a multi-family housing renovation site, after the application of a lightweight screed to reduce the structural load, the application of a fiber-reinforced leveling compound allows for:

• to adjust the flatness,

• to prepare the surface for a PVC coating

• to comply with the planimetry tolerances required by the DTU.

This system continuity secures the entire soil complex.

A comprehensive offering for building professionals

With KRONOS AUTOLIV, EDILTECO® France offers an integrated approach:

• preparation of the substrate (leveling compound),

• application of the screed or lightweight mortar,

• compatibility with finishing systems.

This approach responds to a market expectation: to have access to consistent offer from a single supplierfacilitating procurement and technical coordination.

It is part of an evolution of practices where the performance of a structure is based on the entire construction system, and not on an isolated product.
