Pouring A Basic Concrete Floor

With a concrete floor, you can add a lot of different textures, color, designs, and even stampings to change things up and bring the whole room together. Pouring a concrete floor does require skill and specialized tools. However, you will find that after a little while you start to get the hang of pouring concrete and it becomes a great do it yourself project.

Step 1 - Measure the Amount of Concrete

Find out how much concrete you are going to need. Concrete volume is measured in cubic feet rather than square feet. Multiply the length and width and the thickness of the concrete to find the cubic volume. If you are going to use your bags of concrete, the bag will tell you how much it will cover. Typically, a bag of concrete will handle 1 cubic foot of area.

Step 2 - Build Concrete Forms

Lay out the forms and rebar on the floor you want to cover with concrete. A concrete floor must be level and smooth. To achieve that, use a series of forms to contain the concrete. Build forms around the area you want for a concrete slab or floor by using 2x4 braces coupled with wide planks. It doesn't matter the width of the boards as long as they are wider than the height of the concrete.

Step Three - Lay out Rebar

Rebar adds strength to the concrete. Lay out a criss cross pattern of rebar on the floor of your slab. Using spacers, keep the rebar at least 1/2" to an 1" above the floor bottom.

Step Four - Mix Cement

Mix the cement close to the area you are doing the pour. When you mix your own concrete will you use a cement mixer to mix the water, aggregate and cement products. Once it is to the desired consistency you will either load into a wheelbarrow, or shovel directly into the slab. The closer you are, the easier this is.

Step Five - Pour Concrete and Float Smooth

Pour the concrete into the slab and begin to level it with a float. For larger areas, you would use a bull float which is much longer and can reach more area. For small areas you can use a hand float. The idea is leveling out the concrete floor is to basically push the cement to where it needs to go. It will naturally find the lowest point and fill it. Your job is to continue to push it towards that area while keeping the floor level. A good way to keep it level is to screed the concrete. By putting a long piece of 2x4 across the form, you can slide it across the concrete keeping it all at the same height.

When the concrete starts to set up, run a smoother float over the floor. Once the floor has had time to cure, seal it with a concrete sealer to protect it from any spills and stains.
