How to make a concrete bench
Step 4.4 Top up the bench form
Top up the bench form with more concrete.
In fact, over-fill it, and then....
Screed off the excess concrete.
Use a straight piece of wood to "screed" or level out the concrete.
Work the screed board back and forth with a sawing motion along the tops of the form until the concrete is level all over.
Step 4.5 Attach the leg forms to the bench form
Partially assemble each leg form, with one side panel (b) only, and place them in position on the bench form around the reinforcing wire.
Slipping the angle brackets over the bolts in the bench form will automatically place the leg forms in the right position.
Then add the second panel (b) to each leg form and fasten them in place with the wing-nuts.
Likewise, tighten the angle brackets to the bench form with wing-nuts.
