To begin
- make plans! A
project made with concrete is so permanent that it could become a lasting
monument to your lack of planning! Make sure you know exactly what
you're going to do and who's going to help you before
the concrete arrives.
-
Forms:
Use 2" x 4" planks set on edge. Hold the
2" x 4" in place with stakes driven into the ground every
18 inches. The stakes must be on the outside of the forms and must
be even with the top of the forms.
-
Gather
your tools! Tamper,Garden Hose, Bull Float, Rake, Steel Trowel,
Hand Float, Wheelbarrow, Stakes, Soft Bristle Broom, 2" x 4" Screed Board, Square Nose Shovel. Most of these tools are for rent
at Sandee's Soil and Rock.
-
The concrete
arrives the fun begins! (Make sure you have several people
to help you--at least three people for three
yards or less of concrete.) Wet your area several times the
night before you pour your concrete and sprinkle the ground once before
the cart arrives. This insures a good cure and also keeps the ground
from drawing water from the concrete which means you will have more
time to work the concrete before it sets. Pour concrete out of the
Cart-Away trailer or wheelbarrow.
Begin at the far end of the forms and dump each load close to the
last. Use square nose shovels and rakes to spread the concrete evenly
to the top of the forms.
-
Have two people
use a 2" x 4" screed board to level the
concrete, moving back and forth in a sawing motion as well as across
the concrete.
-
You can use a
tamper to bring moisture and sand to the surface
and to move large aggregate down into the concrete. Don't be afraid
to step out on the concrete but make sure you always move in a backward
direction covering your foot prints as you go.
-
Run an edger lightly
around once following the tamping to establish a groove. This will
simplify final edging.
-
Next, use a long
handled bull float. Back and forth strokes will smooth the
ridges left by screening and tamping.
-
Use the hand
float with flat strokes in an arch motion. Do not apply pressure
or you may cause a rough, sandy finish.
-
Use the edger
again following the hand float to produce a rounded edge that will
not chip easily when forms are removed.
-
When the concrete
can hold a man's weight and not make an impression and when it has
lost its surface moisture, use a steel trowel to
finish the surface. Kneel on a piece of board as you move across the
concrete. Use firm, flat, even pressure in an overlapping circular
motion.(OPTIONAL: you may create a broom
finish after the steel trowel by dragging a broom with very
soft bristles in one direction across the concrete.)
-
To cure
your project, dampen the area daily for 5 days.
-
After you are
finished and cured, remove the forms and enjoy your handiwork for
years to come.
