This step in the finishing operation is the most important in producing a true plane surface and takes place immediately after the spreading of the concrete.
Screeding concrete between walls.
Quality concrete is used for construction and structural tasks while screed is applied as a top layer to a concrete base.
Screeding is the art of skimming or striking off the surface of the concrete after rough raking it.
The skimming device is called a screed.
Concrete and screed are both made from a mixture of cement water and aggregate.
Screeding is the art of skimming freshly poured concrete floors and other surfaces.
But when it comes to their uses as building materials concrete and screed are very different.
Straightedges are used to strikeoff or screed the concrete.
Physical differences between concrete and screed.
Screeding when done properly will leave you with a good even flat surface free of humps bumps holes and low spots.
A good screeding job should leave a surface uniformly flat between two guides without any low spots or holes.
This can usually be accomplished by some diyers on a small scale like a sidewalk for example.
This process removes excess concrete and brings the top surface of the concrete to proper grade.
