What is screeding?
Screeding is a construction technique used to level and smooth out a concrete or other material surface, such as a floor or a wall.
It involves using a straight-edge tool, such as a screed board or a laser level, to remove excess concrete or material and ensure that the surface is even and level.
The process typically involves pouring the concrete or material onto the surface and then using the screed tool to distribute it evenly, removing any excess material and filling in any gaps or voids.
Screeding is an important step in the construction process, as it ensures that the surface is smooth and level, which is necessary for the proper installation of flooring, tiling, or other finishes.

Here are the general steps for screeding:
1. Prepare the surface: Ensure that the surface to be screeded is clean and free of debris and that any necessary groundwork or subflooring has been completed.
2. Place the concrete or other material: Pour the concrete or other material onto the surface, spreading it evenly with a shovel or rake to ensure that it covers the entire area.
3. Set up the screed: Determine the appropriate type and size of screed tool to use, and set it up at one end of the surface. This may involve attaching handles or other accessories, or using a laser level to guide the screed.
4. Screed the surface: Starting at one end of the surface, use the screed tool to level and smooth out the material, moving the tool back and forth in a sawing motion. Apply enough pressure to remove excess material, but not so much that the screed tool sinks into the material.
5. Check the level: Use a level or other measuring tool to check the level of the surface, making any necessary adjustments by adding or removing material with a trowel.
6. Repeat the process: Continue screeding the surface in sections, moving the screed tool along the surface and checking the level as you go. Be sure to overlap each section slightly to ensure a smooth and even finish.
7. Finish the surface: Once the entire surface has been screeded and levelled, allow it to dry or set according to the manufacturer's instructions. You may need to add a finishing layer, such as a coat of sealer or polish, depending on the type of surface you are working with.
Overall, screeding can be a time-consuming and labour-intensive process, but it is an important step in achieving a level and smooth surface for your construction project.
