Do You Have A Screeding Project We Can Help With?

Is it right for the job?


Floor levelling compounds are mainly cementitious and latex thin section, partially self levelling, screeding sytems that can achieve SR1. These systems are commonly used for levelling of pour substrates or the final layer on top of a screed to achieve finer tolerance for the installation of tiles / vinyls, etc. The installation thicknesses vary but there are solutions that range from 1mm up to 40mm in one application and generally have fast drying properties with polymer modifications.

Latex compounds can be either mixed with potable water or as a two part system consisting of powder and a liquid latex bottle.  The mixing process is with an electric mixer to ensure a thorough mix.   Water mixed compounds are sensitive to water dosage and the correct procedures must be made for successful installation.  The substrate needs to be clean, sound and free from dust, plater droppings, grease, paint, polish and loosely adhered material.  It is advised that a primer is used to ensure a complete bond to the substrate and this will also increase the flow of the compound.  The screed can be applied by trowel and a spike roller is recommended to even out the product and then let the product displace to provide an even flat surface.  The standard thickness is 1mm up to 10mm in one application and sometimes sand can be added to bulk out the screed and add additional thickness.  Please refer to manufacturers data sheet at all times.

Cementitious levelling compounds are used to level pour substrates to achieve finer tolerances for the installation of final floor finishes.  The final floor finish can be tiles,c arpet, wood flooring, linoleum, floor epoxy paints, etc.  Cemetitious thin section levelling screeds range from 3mm up to 40mm depending on product and can be either hand or pump applied.  Some compounds are classed as wearing screeds due to their high tensile strength and can be suitable for industrial toppings.  These screeding applications have fast drying properties so final coverings can be installed quickly.  The finishing process is with a spike roller and needs to be at quite a fast rate to ensure the flow of the product.  A carefully prepared surface is required as a solid anchor and correct primer needs to be applied.

Please note:  The data below is provided as a starting point and will vary dependent on site conditions, product selection and working methods, you should always check the latest product data sheets directly from the manufacturer and consult with professionals to ascertain suitability for you projects.
