Mar 25, How to use concrete kneeboards and concrete sliders

I’ll show you how to use concrete kneeboards to mag float a patio slab in preparation for a broom finish.

Concrete knee boards or Concrete Sliders are a finishing tool you use to get onto the concrete and start the finishing process.

The knee boards are used for hand finishing concrete with a mag float and/or a steel trowel. 

By using the knee boards or “sliders” you can start finishing concrete earlier than if you use a power trowel.

Hi, my name is Mike Day. I own this site and I also run a concrete floor business, Day’s Concrete Floors, Inc.

I made a video to show you how to use concrete knee boards or concrete sliders as some people call them.

Being in the concrete floor business, we use knee boards to finish concrete in many ways.

Concrete Finishing Techniques:
Hand Troweling Concrete Smooth

Concrete kneeboards let you get on the concrete a little earlier than you can walk on it, to start the finishing process.

We use them to mag float the surface of a patio before broom finishing or stamping the concrete.

They allow us to slide along the surface without sinking into the concrete.

The advantage of this is being able to fix any imperfections in the surface of the concrete left behind by the bullfloat. 





Sometimes on smaller concrete floors or slabs, we’ll mag float and trowel the floor using just the knee boards instead of a power trowel.

We’ll float the surface once and steel trowel it 3 – 4 times to achieve a mirror smooth floor.

Now we’ve been doing this for a very long time so sometimes this process is just easier for us to do it that way. 

We also use these “concrete sliders” to finish residential floors in the winter that are undercover or decked over and don’t have good ventilation.

If we use a power trowel, there’s a good chance of us getting carbon monoxide poisoning. Been there and done that too many times.

In my business, my guys and I use concrete knee boards almost everyday we pour a concrete floor, patio, or pool deck.

You’ll see in the video just how we use them.

In Conclusion:

I’d highly recommend having a pair of these if you finish concrete. They do make finishing concrete much easier. I know for us they sure do.

Feb 16, Concrete Yardage Calculators – How Much Do I Need For Any Type of Job

Find the perfect concrete calculator to figure cubic yardage (and cubic meters) for any type of concrete project. Floors, slabs, walls and much more.

Calculate concrete cubic yardage for slabs, walls, footings, columns, stairs, blocks, curbs, and gutters using the many different concrete calculators on this page.

Estimate the volume and weight of concrete you’ll need for any given area.

Figure out how many cubic yards of concrete you need in both US units of measure (feet and inches) and International system of units or metric units (meters and centimeters) of measurement.

Concrete calculator

LEARN HOW TO INSTALL YOUR OWN CONCRETE SLAB HERE!

The best way (and fastest way) to calculate concrete yardage is using a concrete calculator.

These concrete calculators are very accurate and will help you determine the volume of concrete you need for the type of project you’re doing.

Always add a little extra to the quantity estimated just to be on the safe side. 

Rarely is any concrete project perfect and you don’t want to be left short on the amount you need.

You’ll be able to calculate concrete cubic yardage, weight, and how many bags you need for:

  • Concrete slabs
  • Concrete Walls
  • Concrete Footings
  • Circular slabs or Tubes
  • Columns or Sono-tubes
  • Concrete Curbs and Gutters
  • Concrete stairs

Concrete calculator formula for a slab or floor

If you want to use a formula to calculate concrete volume, I have a whole page like the picture above that shows you a written formula for:

  1. Square or Rectangular Slabs
  2. Round Slabs
  3. Concrete Walls
  4. Concrete Footers
  5. Square Columns
  6. Round Columns
  7. Concrete Stairs and Steps
  8. Concrete Curbs and Gutters

Concrete calculators for specific applications

Use the concrete calculators below to help you determine concrete yardage for your specific project.


Use the calculators above for estimating purposes only.

Always double check your calculations when you figure concrete for a project. Not having enough concrete to finish can be both frustrating and problematic.

Concrete is made from aggregate (stone), sand, cement, and water.

You can make your own concrete using the raw materials and my concrete mixing ratio formula or you can buy pre-mixed concrete in bags that you just add water to.

For large projects, ordering concrete from a ready mix concrete company is usually easier and faster. 

Learn how to do your own concrete slab by taking my concrete slab course.

The concrete calculator APP for the Iphone and Android smartphone is terrific! I use it daily. The free desktop download is courtesy of Meet-Mr-Concrete.

Learn how I check the sub-grade to find the average thickness of a concrete floor on either the floors or slabs calculator page.

When I order concrete from a ready mix company, I always add 1/2 to 1 yard more than what it says on the calculator.
