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.
Use any 2x4 that overlaps the forms by at least 6 in but make sure it s straight photo 1.
Screeding concrete is one of the first steps in placing and finishing concrete.
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.
Work your way downhill if applicable drawing excess concrete into low spots and holes.
Screeding is the art of skimming or striking off the surface of the concrete after rough raking it.
Screeding should begin as soon as possible after the concrete is poured.
Your goal is to level out marks and fill small holes left by screeding.
Take a 2 x 2 and tack it to the wall 2 above the grade of the finished concrete.
The distance from the bottom edge of the 2 by 6 or 8 to the bottom of the u notch will be 2.
Screeding when done properly will leave you with a good even flat surface free of humps bumps holes and low spots.
Follow screeding immediately with the darby photo 2.
Straightedges are used to strikeoff or screed the concrete.
When you re hand screeding use a sawing motion across the guides as you creep forward along the guides.
