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 against a wall.
Straightedges are used to strikeoff or screed the concrete.
Screeding when done properly will leave you with a good even flat surface free of humps bumps holes and low spots.
Work your way downhill if applicable drawing excess concrete into low spots and holes.
Your goal is to level out marks and fill small holes left by screeding.
Now cut a u shaped notch on the end of a 2 x 6 or 2 x 8 to accept the 2 x 2.
Screeding levels the concrete with the top of the forms and begins the process of forcing the larger aggregate below the surface.
Take a 2 x 2 and tack it to the wall 2 above the grade of the finished concrete.
This process removes excess concrete and brings the top surface of the concrete to proper grade.
Screeding should begin as soon as possible after the concrete is poured.
Screeding is the art of skimming or striking off the surface of the concrete after rough raking it.
When you re hand screeding use a sawing motion across the guides as you creep forward along the guides.
The distance from the bottom edge of the 2 by 6 or 8 to the bottom of the u notch will be 2.
Screeding concrete is one of the first steps in placing and finishing concrete.
