When to use a self-levelling underlayment
Self-levelling and smoothing underlayment compounds, such as TAL Screedmaster and TAL Superscreed SL, are ideal for levelling subfloors in installation areas such as hospitals, clinics and schools, where ‘soft’ (resilient) floor coverings are going to be installed as the final floor finish. These types of floor coverings require a perfectly smooth and level surface, as any surface imperfections in the floor will not only detract from the aesthetic appearance, but can also affect the longevity of the floor covering installation.
Unlike trowel-applied underlayments, that are usually only able to be applied a few square meters at a time, self-levelling underlayments are flowable and designed to be poured over the surface, then spread out to the desired thickness with an appropriate notched floor rake or adjustable floor spreader.
The high-flow and rapid-setting properties result in minimised installation times, making them ideal for fast-track installations. They can also be installed manually or can be pumped for large contracts or upper level floors.
The application of self-levelling underlayment compounds requires professional equipment and trained applicators, and as such, are better suited for installation by experienced installers.
TAL Screedmaster and TAL Superscreed SL are compatible with most commonly used adhesives and soft floor finishes, as well as with hardwood flooring, laminates, tiles and athletic flooring.
