A good concrete floor screed design will include strength, bonding and compatibility with what is to be used over it – whether that be another covering or simply left as a wearing surface. If you require any technical or application support, give Rawlins Paints a call on 0113 245 5450. The traffic and load expectations of the floor will need to be taken into consideration prior to the floor screed’s application to ensure that the strength of the screed will be built to match the required specification.
The Differences Between Concrete and Screed
A key difference between screeds and concrete (which can have the same material ingredients) is that a screed is usually only as a top layer or finish to a concrete base. There is also a different texture between concrete and screed, with concrete being more coarse, rough and containing more aggregate and stones in with the sand and cement. Both floor screeds and concrete can be painted with a heavy duty concrete floor paint, also available at Rawlins Paints. Screed has a smoother texture than concrete, and is more like a mortar with its smaller aggregate components. Once laid, this makes for a much smoother and finer grain appearance than concrete.
How to Screed a Floor
At Rawlins Paints, our focus is on commercial and industrial properties, whose floor space far exceeds domestic settings. Professional applicators with experience of laying and installing these self-levelling floor screeds and compounds, will most likely have adapted their application methods to include things they find helpful to speed up the process and provide a better overall finish. For first time users and professionals alike, each resurfacing screed typically comes with an application guide, and Rawlins Paints’ blog also covers many application techniques for industrial and commercial purposes.
