When it comes to flooring installations, screed plays a vital role in achieving a level, smooth, and durable surface. Screed acts as a base for the final floor covering, providing stability, insulation, and a level substrate. Whether you’re working on a residential, commercial, or industrial project, understanding the process and importance of screed installation is essential. In this comprehensive guide, we will explore everything you need to know about screed installation, from its purpose and types to the step-by-step installation process and tips for achieving the best results.
Screed is a thin layer of material applied over a concrete or subfloor to create a level and smooth surface for the final floor covering. It acts as a protective layer, improving the structural integrity of the floor and enhancing its performance. Screed can be composed of various materials, such as sand and cement, self-leveling compounds, or synthetic resins, depending on the specific requirements of the project.
There are different types of screed available, each suited for specific applications and project requirements:
Screed is used in a wide range of applications within the construction industry, but it is essentially a thin layer of material, similar to concrete, that is most commonly applied to a concrete subfloor or over insulation.
Screed is typically made from sharp sand, cement and water – in a ratio of around 1:3 or 1:4 of cement / sharp sand. There are a number of additives that can also be used to improve certain characteristics, for example, a faster drying time, improved thermal conductivity for underfloor heating, or increased strength. Additionally, screed can be reinforced with a wire mesh if required.
Learn the pros and cons. An unbonded screed sits on top of plastic sheets instead of directly on the concrete below. This protects your floor from moisture in the subfloor, and from settling and other issues in the main structure. However, an unbonded screed is more likely to curl. Reinforcing can help with this problem, as described below.
Clean the concrete base. Remove all dust and grease from the concrete before you begin the project.
Cover the floor in plastic sheeting. Lay down polyethylene or PVC sheets to separate the concrete from the screed layer. Overlap sheets by at least 20 cm (7.9″) and tape them together. Fold the sheets up 10 cm (3.9″) onto all walls and pillars.
Line walls and pillars with compressible material. This protects these surfaces from damage when the screed shrinks. You may use edging foam, 20mm (0.8″) kingspan insulation, or 1 cm (2.5″) polystyrene.
Reinforce the screed. Unbonded screed is at greater risk of micro cracks, which reduce its strength. Reduce this risk with one of the following approaches:
