floor slab can be finished in many ways, depending on its intended use:
- Screeding – This is carried out on all floors.
It spreads the concrete evenly to the required surface level, giving the
surface a basic level of flatness and levelness.
- Floating – This is carried out on all floors.
It brings the fat to the floor surface, allowing finishes which rely on surface
fat, such as trowelling, to be performed.
- Trowelling – This is mainly carried out on
internal floor slabs. It squeezes water out of the paste closest to the
surface, densifying and sealing it to provide a tough working surface.
- Texturing of the surface – This is carried out on slabs where
slip resistance is important and flatness isn’t an issue e.g. external slabs.
important aspect to consider when applying these finishes is the timing of each
process. If the timing is misjudged, it can completely ruin the final finish in
All of these finishing methods can be carried
out by hand. However, for large surface areas, such as industrial concrete
floors, machines are used.
