WHAT IS SCREEDING CONCRETE?

Screeding concrete is the process of leveling and smoothing freshly poured concrete using a screed, which is a straight board, typically made of wood or aluminum, that is pulled across the surface of the concrete. This process removes excess concrete and helps to create a smooth, level surface that is ready for finishing. Screeding is typically done by hand or with a power screed, which uses a vibrating motor to level the concrete. It is an important step in the construction of a concrete surface, as it ensures that the surface is level and uniform, which is essential for the durability and longevity of the concrete.
TOOLS AND MATERIALS REQUIRED
First of all, before we start work, we need a list of tools and materials needed for the concrete screed as follows:
Tools required for Screeding Concrete:
Tools required for Screeding Concrete
- Bull float: A large, flat tool used to smooth and level the surface of the concrete.
- Builder’s barrows (with inflated rubber tires).
- Timber planks/ramp to wheel the barrow over if the ground is uneven or soft
- One or two square-mouthed shovels.
- A screed board – a smooth, heavy board about 900mm wider than the formwork
- A wooden float (a flat piece of wood with a handle) for finishing the surface.
- A steel trowel, if needed
- Protective tools for builders: Gloves, Safety glasses, Knee pads, Rubber boots
Materials required for Screeding Concrete:
Sand and cement mixture
Materials required for Screeding Concrete
- Concrete mix
- Reinforcement mesh or bars
- Plastic sheeting or vapor barrier
- Screed rails (if needed)
- Concrete curing compound
- Water (for mixing the concrete and cleaning tools)
TIPS & TECHNIQUES FOR A PERFECT CONCRETE SCREEDING
Whether you are new to concrete work or an experienced builder, here are some tips and techniques to help you achieve a perfect finish when screeding your concrete.
1. Properly prepare the sub-base
Before you start screeding, it’s important to ensure that the sub-base is level and properly prepared. This will prevent any unevenness or settling of the concrete later on. Use a compactor to compact the sub-base and ensure that it is firm and stable. Remove any debris and ensure that the surface is clean and dry.

2. Use the right tools
Various types of screeding tools are available, including a straightedge, a screed board, and a bull float. A straightedge is used to level the concrete, while a screed board is used to spread the concrete evenly across the surface. A bull float is used to smooth and finish the surface.
3. Start with the right mix

The right mix of concrete is essential for a perfect finish. The mix should be smooth and creamy, but not too wet or dry. The ideal consistency is similar to peanut butter. Use a concrete mixer to ensure that the mix is well-blended and uniform.
4. Work in small sections

To ensure that the concrete doesn’t dry too quickly, work in small sections. This will give you enough time to spread and level the concrete properly. Start at one end of the surface and work your way toward the other end. Use a screed board to spread the concrete evenly across the surface and a straightedge to level the concrete.

5. Keep it level
Use a steel trowel to adjust the concrete layer
One of the most important things to remember when screeding concrete is to keep it level. Use a level to ensure that the surface is flat and even. If you notice any low spots, add more concrete to those areas and level it again.
6. Finish with a bull float

Once you have screeded the concrete, use a bull float to smooth and finish the surface. Move the float back and forth across the surface to remove any high spots and create a level finish. Be careful not to over-finish the surface, as this can cause it to become too smooth and slippery.
In conclusion, screeding concrete is an important process in construction that requires attention to detail and the right tools. By following these tips and techniques, you can achieve a perfect finish floor every time.
