Have a helper add or remove concrete in front of the screed as you pull it.
How to screed concrete next to wall.
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.
Next divide the slab into equal parts with a straightedge and groover photo 5.
Set a floating form or a pipe screed along the length of the pour.
This process removes excess concrete and brings the top surface of the concrete to proper grade.
Add grooves every 10 or 12 ft.
Sidewalks and small slabs need grooves about every 4 ft.
Make multiple passes if needed to create a flat evenly filled area.
It must be completed before excess bleedwater appears on the surface.
If the edger is leaving a path deeper than about 1 8 in wait for the concrete to set a little longer and apply less downward pressure.
This is a guide to keep the screed at the correct height so that the concrete finishes off flat.

Or a better option would be an aluminum screed.
Drag a straight 2 4 screed board across the top of the concrete forms to level the concrete.
When you re hand screeding use a sawing motion across the guides as you creep forward along the guides.
Hand screeds can be a straight wood 2x4.
On driveways and garage slabs.
If the smooth surface begins tearing then your travel along the guides is too fast.
Work your way downhill if applicable drawing excess concrete into low spots and holes.
Straightedges are used to strikeoff or screed the concrete.
