How to Broom Finish Concrete
If you know how to broom finish concrete you have successfully managed to counter one of the disadvantages of concrete: its slippery surface making it dangerous to walk on, especially for children. Concrete is certainly among the top surfaces when it comes durability. However, the slippery element makes homeowners think twice. A simple broom finish will provide greater friction, making it safe for people to walk on without affecting the durability of the concrete. The extra effort that is needed for a broom finished concrete should certainly fall in your list of do-it-yourself tasks.
Step 1 - Build, Level, and Fill the Concrete Forms
First form the concrete slab and then pour it in accordance with the standard concrete installation methods. These methods include, constructing the forms from wood and then leveling them. Then simply fill up the forms with cement and use a straight board to level the concrete. Hold the straight board crossways on the top of the concrete form and slowly move it across the surface.
Step 2 - Finish the Concrete Exterior with a Trowel
Use a trowel to finish the surface. The trowel is used to smooth out the surface and level it. Using a trowel to finish the surface will also help work the tiny rocks concealed in cement to the base of the surface and bring the cement-water mixture at the top.
Step 3 - Broom Finish the Concrete Surface
Take a concrete broom and run it across the concrete surface. You have the option of using a regular household broom but it is recommended for better results that you employ a concrete broom that professionals use to broom finish concrete. Hold the bristles of the concrete broom at approximately a 45-degree angle with the cement. Keeping in mind in which direction people usually walk on the surface, pull the broom from one corner of the surface to the other in that direction at a 90-degree angle. Now shift the broom to the edging of the surface where you have applied the broom finish.
Step 4 - Consistency and Edges
Keep the pressure exerted on the cement uniform at all times to ensure that a consistent set of marks are produced on the cement. Then move onto the edges of the concrete slab and finish them. This is where an edge trowel comes in handy. Use the edge trowel to round off the edges of the concrete slab and make a flat margin. This helps form a consistent border for the broom part of the concrete slab finish. However, do not undo your work by allowing people to use it immediately. Give the cement adequate time to dry off before allowing people to walk on the concrete slab.
