In this video I show from start to finish how to prepare, form and pour a 6/" thick concrete slab reinforced with 1/2/" rebar.

Common tools/materials for finishing concrete:

Mixers:
Whether you mix in a truck, a portable mixer or a wheelbarrow, you want to be sure your concrete is thoroughly mixed for maximum strength and durability.

Wheelbarrows
Ideal for transporting (or even mixing) small batches of concrete or tools on the construction site.

Rubber boots or work boots
Concrete is stiff stuff, and wearing waterproof boots is the best way to get through it and avoid contact with your skin. It is also easy to rinse your shoes after the concrete has fallen.

Compactors
If the concrete slab location requires preparation with a subbase of any type, a compactor will help set the stone or aggregate in place.

Levels
Both the subfloor and the slab surface must be level. Using a standard long-line spirit level or a laser level you can check whether the slab fully complies with specifications, before pouring and afterwards.

Measuring tapes
Concrete forms and slab depth require the same “measure twice, pour once” verification as any other material on the job site.

Saws
Reciprocating saws, circular saws or grinders may be necessary to cut reinforcement or shapes on the construction site. They may also be necessary if there is a problem under the slab and some of the concrete needs to be removed after it has hardened and dried.

Kick
Shovels help distribute concrete around the construction site to fill gaps created during the pouring process or for smaller applications. Square-ended shovels generally work better for concrete; rounded ones spread the concrete unevenly.

Rakes and take-along rakes
Using a rake is the fastest way to get the freshly poured concrete into place more evenly. Garden rakes work, but concrete rakes, also called take-along rakes, have a more scooped blade to make it easier to pre-level new concrete. Concrete rakes also have a tooth on the back of the blade to lift rebar or mesh into place before the concrete begins to harden.

Trills
Concrete vibrators help release trapped air pockets and excess water from the concrete mixture to prevent potentially compromising problems in medium to high slump concrete.

Screeds
Screeds come in different sizes and can be a specific tool (also called straight edge or butt cutters), or they can be simple flat pieces of dimensional lumber. The purpose of a screed is to smooth concrete after it has been placed in place by scraping away excess material from the slab surface.

Taurus floats
Bull floats are tools with wide blades on a long (possibly telescoping handle) that provide the first pass for leveling ridges and filling voids in the concrete after decking work has been carried out.

Magnesium floats
Magnesium floats (or mag floats) are smaller hand floats typically used to float slab edges or to use for finishing work on smaller slabs.
Kneeling planks
Especially when using manual trowel work, kneeling planks provide a smooth way to support your weight on the wet concrete while moving easily over the slab surface.

Leveling concrete trowels
Trowels also help smooth concrete surfaces for their finishing coats before drying. For smaller slabs, manual troweling is common, while for large slabs, electric trowels are often preferred. There are different types of trowels for specific concrete work.

Float blades and trowel blades
A variety of blade types are available for floats and trowels, each designed to achieve different finishes. During the troweling phase, some care must be taken not to polish the surface and prolong the drying time.

Grooving cutter/joint tool
For certain types of work, grooving the surface also helps prevent cracking or excessive damage from shrinkage as the concrete dries or during use.

Rander
An edger is a tool designed to round off exposed concrete edges for a smooth finish.
