Screeding Concrete Against A Wall

Screeding should begin as soon as possible after the concrete is poured.

Screeding concrete against a wall.

Work your way downhill if applicable drawing excess concrete into low spots and holes. Follow screeding immediately with the darby photo 2. Use any 2x4 that overlaps the forms by at least 6 in but make sure it s straight photo 1. Wow 2 thumbs down for the best answer i have used homosote expansion joint and i have used coil stock coil stock is the best choice in my opinion even if you poured against the sill plate and ran a bead of concrete caulk along the seam when it was set it would be ok there should be enough slope that water shouldnt be that much of an issue most inspectors dont have a clue anyway.

This process removes excess concrete and brings the top surface of the concrete to proper grade. When you re hand screeding use a sawing motion across the guides as you creep forward along the guides. Screeding when done properly will leave you with a good even flat surface free of humps bumps holes and low spots. 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 is the art of skimming or striking off the surface of the concrete after rough raking it. The conventional way to handle this problem is to use a length of 1 5 or 2 inch diameter pipe as the screed reference level. It can be cork 1 2 thick by 4 tall set to the wall with short pins to hold it while pouring. Straightedges are used to strikeoff or screed the concrete.

Typically when i pour concrete against a house foundation never pour concrete against any siding imho it invites trouble later i have an expansion joint set to the house. The stakes are pounded in so that their tops are the pipe diameter below the intended concrete height. This pipe sits on top of a series of stakes that you place in the ground in a line a few inches from the brick wall. Screeding levels the concrete with the top of the forms and begins the process of forcing the larger aggregate below the surface.
