Oct 2019 CONCRETE FINISHING TECHNIQUES
Offering an unending variety in choice, concrete installations can be poured or cast into different designs, forms and functional installations finished with a number of varying techniques. Manipulated either by alternative concrete finishing techniques, different materials used, exposed aggregate concrete or a combination of a multitude of methods, the appearance of concrete and especially in the case of floor finishes, can be vastly different based on different types of finishing techniques applied. For the most part concrete floor finishes, if not modified will cure with a smooth to semi smooth surface. While this finish is ideally suited if the flooring will later be finished with tiles, carpets or laminate flooring, there are a number of concrete finishing techniques that will result in an aesthetically appealing appearance without any further styling.
Sephaku Cement explores various concrete finishing techniques unlocking a world of versatility in concrete floor finishes.
- ScreedingJust as concrete has been placed, using an aluminium tool to smooth out the surface, screeding concrete will result in a supremely smoothed concrete surface as the screed board or floating screed is guided over the surface of wet concrete. This concrete finishing technique can be further enhanced by adding a concrete stain to the surface of the screeded concrete. Through the application of either an acid stain to the surface of screed concrete floors or alternatively by adding pigment when initially mixing the concrete, concrete staining and pigmentations add a vibrant accent to concrete floor finishes with a flash of colour from a vast selection of options.
- TrowelingAfter applying an initial screeding technique to wet concrete, manual or power float concrete finishing techniques can be applied to further smooth out concrete installations. By using either a handheld flat steel blade fitted to a handle or a power trowel ideally used on larger surface areas, trowelling concrete surfaces will further refine grooves and edges for a more polished concrete finish and glossy appearance.
- Rounded EdgingBevelled edging results in the sloped or rounded boarders of placed concrete installations. Where wood box moulds cast sharp precise corners, bevelled concrete edging tools will see softer borders with either a round or angled gradient and a more refined finish. Employing a specialised edging tool to achieve this finish, the same tool can also be used to guide intentional concrete joins in the directing of concrete cracks. Bevelled edging and control joints may also be achieved from stamped concrete installations. Provided the concrete stamp stencil echoes the same bevelled edged as the handheld edging tool, the same finish can be achieved as stamped concrete at a fraction of the time (and expense) especially when applied to larger areas.
- Broomed or Brushed FinishNot the most elegant or refined concrete finishing technique, but an effective method to adding traction as a slip resistant solution or an artistic texture to typically smooth concrete or plaster. A brushed concrete finish is achieved much as its name suggests, by running a clean hard bristle broom over the surface of recently placed concrete , a broom finish creates a scrubbed or grazed surface and can be created either in long straight strokes or a circular motion to create skimmed swirls
