There is no single answer to the question of latex screed thickness, the correct depth and type of floor screed will be dictated by many factors including architecturally specified floor finishes, construction tolerances and provision of falls. The design should also take into account structural requirements such as preventing disproportionate collapse and composite action with the concrete slab beneath.Learn more :

The type of floor finish will also dictate the level of floor screed required, if underfloor heating is being installed the pipes must be placed in the floor screed and this will increase the overall depth of the floor screed. In some situations it may be beneficial to use a self-levelling screed or other modified type of floor screed where a higher strength is required and it will provide a more durable surface for the final floor covering.

Optimizing Performance: Choosing the Right Latex Screed Thickness

In some cases, particularly where the floor is to be used as a wearing surface, it may be advantageous to use a concrete-based floor screed or a reinforced cement sand bonded screed to reduce shrinkage potential and control the drying process. This will generally require the inclusion of mesh reinforcement to mitigate curling, which is a common problem with conventional power floated concrete floors and the specification of admixtures such as GCP Applied Technologies’ Eclipse 4500 (shrinkage reducing) can also be helpful.

The most important thing to remember is that it is the responsibility of the specifier, and not the contractor, to specify the correct depth and type of floor screed. It is also vital to carry out appropriate calculations for the required strength and ensure that expansion joints are specified and that a hold point is included in the specification for inspection of the formed expansion joint prior to installation of the floor finishing.
