How Does Self-levelling Compound Work?
Self-levelling compound is a cement-based mixture used to smooth and level uneven subfloors before the installation of flooring materials such as tile, hardwood, laminate or carpet. It is a popular choice in construction and renovation projects because it naturally creates a flat, even surface, which is the perfect underlay for the final floor choice.
Here’s how a self-levelling compound works:
Composition:
Self-levelling compounds are typically composed of cement, fine aggregates and other additives. The specific formulation can vary, but the main goal is to create a flowable mixture that can spread and settle evenly across a surface.
Flowability:
The key feature of the self-levelling compound is its ability to flow and spread out evenly across the surface. When prepared correctly, the self-levelling compound becomes a low-viscosity liquid, gravity and surface tension work together to level the compound.
The low viscosity of the self-levelling compound mixture enables it to flow and settle into depressions and irregularities in the subfloor. As it spreads it will naturally fill in low spots or irregularities. The surface tension helps the compound maintain a uniform thickness across the entire area. These characteristics are beneficial, as they address unevenness in the subfloor, preparing the surface for the final finish.
Setting and Curing:
After application, the self-levelling compound sets and cures, our self-levelling compounds can be ready to walk on in as little as 24-48 hours. During this time, it hardens and becomes a solid surface.
Compatibility:
Self-levelling compounds are versatile and can be used on various subfloor materials, including concrete, plywood, and existing tile, as long as the surface is prepared correctly.
It’s important to note that proper surface preparation, including cleaning, priming, and addressing any structural issues, is essential for the correct application of self-levelling compounds.
