Self-levelling compounds are specifically formulated to improve the flatness and uniformity of the substrate. This creates an ideal base for the final floor covering, be it tiles, carpet, or wood. This guide explores the facets of self-levelling compounds, including their composition, modes of application, and inherent advantages.

These compounds essentially synthesise cement, polymers, aggregates, and additives. Each plays a pivotal role in ensuring the compound&#;s performance, workability, and durability. Polymers augment the compound&#;s flexibility and adherence properties. On the other hand, the additives are integrated to modulate the flow, set time, and enhance other functional properties. The amalgamation of these components ensures that self-levelling compounds effectively rectify any substrate discrepancies, delivering a uniformly levelled surface ideal for any flooring type.

What is a self-levelling compound, and what is it composed of?

A self-levelling compound is a highly specialised, hybrid flooring solution primarily used to rectify and mitigate imperfections in the substrate, creating a smooth and level surface for subsequent floor installations. It is a fluid material that autonomously levels out, filling in depressions and eliminating protrusions. Hence, it is used extensively to correct surface irregularities like dips, bumps, or cracks on subfloors.

Detailed composition:

The composition of a self-levelling compound is predominantly comprised of the following components, each contributing to its unique properties:

• Cement: Acts as the foundational base of the compound, providing rigidity and structure.
• Polymers: These are incorporated to enhance the compound&#;s flexibility and adhesion, enabling it to bond efficiently with diverse substrates, accommodating minor movements and fluctuations in the substrate without compromising integrity.
• Additives: Specific additives are integrated to modulate and optimise the flow characteristics and setting time of the compound, ensuring a seamless, even spread over the substrate and aiding in the attainment of a flat, uniform surface.
• Aggregates: These are granular materials that provide bulk, stability, and structure to the compound, aiding in achieving the desired consistency and thickness.
• Pigments: Some compounds may contain pigments to impart colour to the compound, which could be advantageous in certain aesthetic or functional applications.

Upon application, the self-levelling compound spreads and levels itself out due to its low viscosity and optimised flow properties, filling in low spots and levelling high spots, thus creating a uniform, smooth surface. The refined balance of components in the compound ensures that it maintains its shape and structure once set, providing a stable and reliable base for subsequent floor coverings.

This foundational layer is pivotal for the longevity and quality of the overall flooring system. It rectifies substrate irregularities, preventing future issues such as cracking, debonding, or uneven wear in the final floor covering.

Types of self-levelling compounds

There are three major types of self-levelling compounds. Understanding their composition dictates their use. For example, residential properties and commercial spaces will have different requirements. However, the ultimate goal is to achieve dimensionally stable and level surfaces.

Water-based compounds

• Application: Ideal for residential and light commercial spaces due to their cost-effectiveness and ease of application.
• Characteristics: These are usually less viscous, user-friendly, and emit lower VOCs (Volatile Organic Compounds).
• Substrates: Suitable for concrete, wood, and other standard subfloor materials.
• Limitation: They might not be suitable for areas with heavy loads or extreme conditions due to lower strength and resistance.

Latex-based compounds

• Application: Preferred for surfaces prone to movement or vibration, such as wooden floors, due to their enhanced flexibility.
• Characteristics: They exhibit superior adhesion and flexibility, reducing the risk of cracking or debonding.
• Substrates: Ideal for substrates like wood, which may exhibit movement or dimensional instability.

Application steps

Before applying a self-levelling compound, it&#;s critical to prepare the substrate to ensure optimal adhesion and performance meticulously. Start by thoroughly cleaning the surface and removing any traces of dust, dirt, grease, oil, or loose and deteriorating materials. This step is imperative as contaminants left on the substrate can impede the compound&#;s adhesion, leading to future failures. Consider using a degreasing agent or an industrial cleaner for surfaces with stubborn contaminants like oil or grease.

Once the cleaning is complete, assess the substrate for any cracks, holes, or other damages and repair them using a suitable patching compound. After repairs, the application of a primer is crucial. A primer enhances the bond between the substrate and the levelling compound, preventing pinholing and bubble formation issues. Ensure that the chosen primer is compatible with the levelling compound and apply it per the manufacturer&#;s instructions, allowing adequate drying time before proceeding to the next step.

2. Mixing the compound

The mixing process is a pivotal step, and precision is key here. Accurate measurement of the compound and water (or any other recommended liquid) is essential. Follow the manufacturer&#;s specified ratio diligently to avoid inconsistencies in the mixture. Use a mechanical mixer to achieve a lump-free, homogenous consistency. Avoid overmixing as it could introduce air bubbles into the mix, leading to problems during application. Once mixed, the compound should be used immediately, considering its rapid-setting nature.

3. Application of the compound

Pour the mixed self-levelling compound strategically, starting from the furthest point of the room and working your way towards the exit. The compound should also be poured evenly over the surface, allowing it to flow and level out. Utilise a squeegee or a gauge rake to assist in spreading the compound to the desired thickness, ensuring it covers the entire area uniformly. Adhering to the manufacturer&#;s recommended application thickness is crucial to avoid cracking or insufficient coverage. A trowel can also be used to spread the compound manually for areas that are hard to reach or for detailing.

After application, the self-levelling compound requires a sufficient curing period to achieve its full strength and properties. The drying time can vary depending on the type of compound used, ambient conditions like temperature and humidity, and the thickness of the application. Generally, it ranges between 1 to 3 days. During this period, it is paramount to avoid any traffic or disturbance to the area to prevent imperfections or damage to the freshly applied compound. Adhering to the manufacturer&#;s recommended drying time ensures the compound is adequately set before installing the final floor covering.

Advantages of self-levelling compounds

Uniform and smooth surface

One of the primary advantages of self-levelling compounds is their ability to provide a uniform and smooth surface, which is crucial for the optimal installation of final floor coverings. These compounds meticulously fill in the depressions and rectify undulations on the substrate, eliminating irregularities and imperfections. A smooth, flat surface is indispensable for the longevity and performance of floor coverings such as tiles, laminate, or carpet, ensuring they are laid evenly and securely.

Rapid application and setting

Applying self-levelling compounds is relatively swift and straightforward, significantly reducing downtime in construction or renovation projects. Many of these compounds are formulated to set and cure rapidly, allowing for the progression to subsequent stages of the flooring installation in a shorter timeframe. This setting is particularly advantageous in commercial settings, where minimising operational disruption is critical.

Enhanced durability and strength

Self-levelling compounds are imbued with properties that enhance the floor structure&#;s durability and strength. They are a robust intermediary layer between the substrate and the floor covering, distributing loads and stresses evenly across the surface. This uniform distribution of stresses mitigates the risk of cracking, deformation, and other structural damages to the floor covering, prolonging its lifespan and maintaining its aesthetic appeal over time.

Versatility and compatibility

Self-levelling compounds are versatile and compatible with various substrates, including concrete, wood, and tiles. This versatility is augmented by the availability of different compounds, each tailored to meet specific requirements and conditions of the project. Whether it&#;s a high-traffic industrial floor requiring chemical resistance or a residential space needing aesthetic appeal, there is a suitable self-levelling compound that can cater to diverse needs and preferences.

Accommodates varied floor coverings

The use of self-levelling compounds is not restrictive to specific floor coverings. Once cured, these compounds can accommodate varied floor coverings, including tiles, carpet, vinyl, and wood, providing ample flexibility in choosing the final floor&#;s desired aesthetic and functional attributes. Adapting to different floor coverings allows for greater design freedom and customisation, enabling the realisation of distinct architectural visions and preferences.

Things to consider

Substrate condition and preparation

Before applying a self-levelling compound, examining the substrate&#;s condition thoroughly is crucial. Any presence of contaminants, loose materials, or structural damage on the substrate can compromise the adhesion and performance of the compound. Proper preparation, including cleaning and repairing the substrate, is fundamental to achieving optimal results. Substrate moisture levels should also be evaluated, as excessive moisture can lead to failures such as debonding or blistering of the compound.

Material selection

Choosing the appropriate type of self-levelling compound is essential, considering the specific requirements and conditions of the project. Factors such as the substrate type, environmental conditions, desired drying time, and the intended floor covering should influence the selection. For instance, epoxy-based compounds may be more suited to industrial environments due to their enhanced strength and chemical resistance. In contrast, due to their flexibility, latex-based compounds might be preferable for surfaces prone to movement.

Manufacturer&#;s instructions

Adherence to the manufacturer&#;s instructions is paramount throughout the process, from mixing to application. Instructions typically include guidelines on the proper mixing ratios, drying times, and application thickness. However, deviations result in inconsistencies, poor performance, or failures of the compound. Reading and following the product datasheet and guidelines ensures the compound is prepared, applied, and cured correctly, optimising its performance and durability.

Ambient conditions

The environmental conditions during the application and curing of the self-levelling compound can significantly impact its performance. Temperature and humidity levels should be within the recommended range to prevent issues such as improper curing, cracking, or poor adhesion. Protecting the area from direct sunlight, wind, or precipitation is also essential, particularly for outdoor applications, to avoid rapid drying or contamination of the compound.

Budget and cost-effectiveness

Economic considerations should also influence decision-making. While self-levelling compounds are a valuable investment for achieving high-quality floors, balancing costs with project requirements and budget is essential. Opting for cost-effective solutions without compromising quality and performance is crucial. Therefore, exploring various products and their cost implications can help make informed, economically sound decisions.

1. Substrate preparation

To find out if your current substrate is suitable for the microcement installation please use our Substrate Preparation &#; Recommendation Table tool. 

When installing microcement on a screed or concrete surface, the surface must meet certain requirements. These requirements include being level, clean, cured, dry, dust-free, and free of substances that could hinder adhesion. Microcement cannot be applied on non-solid substrate with any type of movement issues.

Want more information on Self-Leveling Compound Manufacturer? Feel free to contact us.

For the microcement flooring  the substrate to

be solid, load bearing, level, fully cured, stain free with a minimum tensile strength of 1.5 N/mm2 and dry maximum humidity allowed 4%.  

Any self levelling compound used as a subfloor should be load bearing.

If the microcement is being installed on a new screed or concrete floor or plastered walls, it is important to ensure that the surface had enough time to cure and is free of moisture. It is common for freshly screeded floors to appear crack-free at first glance, but only after applying our bonding sealer/primer &#; No1 Sealer, will you be able to fully assess the condition of the subfloor.

Microcement can be applied to various surfaces such as tiles, glass, metal, screed, concrete, green MDF, and marine plywood. However, it should not be applied to wooden or laminated floors due to potential movement issues.

Before applying microcement, it is crucial to carefully inspect the subfloor for any cracks, moisture issues, unevenness, or movement issues. These issues must be addressed before installation begins.

All external areas must be water-tight and protected from wind, and roofs must also be water-tight. Prior to installation, any pipework and underfloor heating systems must be tested to ensure there is no water ingress, which can affect the curing process and final finish of the microcement.

Microcement should not be used as a levelling material as it is not time or cost effective. Instead, self-levelling compound, screed, or our FIX ALL mortar system can be used.

When applying microcement on dry-lined walls, there are two options: plastering or taping and jointing. Plastering involves applying tape to joints and then coating the entire surface with plaster. Taping and jointing involve taping the joints and then applying three coats of jointing compound to the joints only.

When applying microcement to the walls with the cement boards on then either plastering or ClaudiCemento FIX ALL system should be used first as part of the substate preparation.

When applying microcement to the substrate with moisture issues such as damp, and/or in the basements , and /or in the outdoor areas then ClaudiCemento HYDRO FIX should be used first as part of the substate preparation.

When creating a furniture that is designed for a microcement coating, double up on moisture-resistant Green MDF, glue and screw it from the bottom, and flush and overlap the joints.

Proper attention must be paid to joints and movement during floor or wall preparation, as any future movement can result in cracks.

Under floor heating (UFH) should be turned off at least 3 days before application and can be turned back on after 28 days. Microcement cannot be applied directly on UFH pipes, as the substrate for microcement installation must be solid and load bearing. 

Existing expansion joints should be mirrored, and any new ones should be designed by architects or structural engineers.
