Adding a concrete patio is an easy, affordable way to enhance a blank-slate backyard. Anyone can use Quikrete concrete mixes to pour a slab and extend their living space outdoors. Even better — It doesn’t require special training or skill sets — just follow the package’s instructions. But before you get to work, remember: safety first. Follow these tips on how to broom-finish concrete.
Whether you pour a concrete slab or use Quikrete Re-Cap Concrete Resurfacer on an existing slab, you need to add texture so it doesn’t become slippery when wet. With new concrete, this step happens following most of the finishing. After you’ve leveled the surface and smoothed it with floats and trowels, use a broom to add a small amount of texture.
We recommend doing this when the concrete has cured to the point that it is becoming solid but is still soft. Learn more about how long it takes concrete to dry.
When Is Concrete Ready for a Broom-Finish?
Concrete is ready for broom-finish when it is firm enough not to surrender to a push of a finger or hand and soft enough on top to accept marks from a stiff broom.
When you resurface an existing slab with Quikrete Re-Cap Concrete Resurfacer, the process is the same. Ensure that the concrete is hard enough that the broom won’t remove the resurfacer and not too soft that it won’t create the necessary texture.
It may take some practice to find that happy medium between when it’s too early to finish and when it’s too late. A good rule of thumb is to press a finger on the concrete and ensure you can’t leave an imprint.
And if there’s not an imprint, lightly score the surface. That’s when the fun begins.
Technique Basics for Broom Finishing Concrete
Whether you want simple straight lines or an artistic pattern, mastering the basics of broom finishing is straightforward. Keep these core techniques in mind to ensure your success:
- Use a stiff bristle broom with synthetic (nylon) or natural (horsehair) fibers to imprint the concrete. Stiff bristles are key for leaving an imprint.
- Pour a concrete mix designed for broom finishes that contain retarders to slow drying time. Working time is critical.
- Wait until the slab is walkable but still soft enough for broom imprints. The timing window is narrow, so test different moments.
- Lightly drag the broom across the surface using consistent pressure and direction. Too much pressure can undo the smooth finish.
- For decorative looks, experiment with different bristle textures, colors, and movement patterns. The right timing takes practice.
Creative Ideas for Decorative Broom Patterns
The importance of broom finishing for both texture and visual appeal is evident. You can lightly drag a broom in one direction over the concrete as a safeguard. You also can get creative by adding fun designs.
Whether you go for the tried-and-true straight drag or added character with different shapes and colors, you’ll end up with an attractive, safe surface. Here are ideas to make your broom finish unique:
- Multi-directional: Alternate the direction of broom strokes to create a zigzag or diamond pattern.
- Circular: Sweep the broom in circles or curved lines rather than straight lines.
- Borders: Outline a border with a different broom texture or color.
- Geometry: Try square or triangular broom imprints for a modern look.
- Colors: Tint the concrete or use colored broom fibers for extra pop.
Let your creativity guide you while maintaining proper texture for safety.
Choosing Broom Types and Bristle Materials
Not all brooms are equal when it comes to finishing concrete. Bristle material and stiffness play a big role in how well the broom imprints the surface. Here are good options:
- Horsehair: The classic choice offering subtle lines.
- Nylon: Extra-stiff synthetic fibers create deeper imprints.
- Polypropylene: Softer than nylon for very smooth finishes.
- Plastic: For basic utility finishes.
Thicker broom heads imprint more concrete per pass. Wider brooms cover more area. We recommend testing different brooms on leftover concrete to find your favorite.
Tips for a Quality Broom Finish
Here are more tips to get a high-quality broom finish:
- Use a magnesium float to smooth the concrete before finishing, and leveling the surface.
- Wait until all the water on top evaporates before imprinting. If you imprint with water, it weakens the design.
- Work in sections for the best coverage and consistency.
- Keep broom strokes uniform in direction and pressure. Overlap for consistency.
- Rinse and dry the broom between uses to keep the bristles clean and stiff.
- Avoid overlapping corners. Broom up to edges but not across them.
- Apply a cure-and-seal product after finishing to protect and enhance the finish.
Patience is key. Wait until the slab is ready before finishing. Rushing the process risks undoing smooth finish work.
Caring for a Broom Finish Over Time
With proper maintenance, a quality broom finish can last decades. Our experience tells us that sweeping regularly with a stiff broom helps prevent dirt buildup. Use a pressure washer on low settings to deeply clean without damaging the concrete. We also recommend re-applying a cure and seal product every two to three years for additional protection.
To prevent unintentional damage, avoid dragging sharp or heavy objects across a finish that can swatch easily. Remove standing water and ice to prevent freeze-thaw damage, and periodically re-apple colored finishes and stains to refresh the look.
Also, repair cracks and pits as soon as possible to prevent deterioration, but use caution with any chemicals. Wear gloves and eye protection. Following manufacturer guidelines ensures maximum durability. Consult a concrete professional if you’re unsure about repairs.
So, Is Broom-Finishing Concrete Worth the Effort?
If you want the safest, best-looking concrete, broom finishing is mandatory. The minimal extra time and costs are worthwhile. Small ridges from stiff bristles create traction, preventing slippage. Unfinished concrete becomes dangerously slick.
Broom finishing also provides texture and appeal to a bland slab. With creative patterns, borders, and colors, it becomes a decorative landscape element.
Anxiety may grip newcomers because of the fast timing needed to imprint textures. But with practice and patience, you can master the basics. Starting with a single-direction utility finish before trying fancy designs is wise. Get comfortable with the timing and textures first.
While broom finishing requires attentiveness, the reward is concrete which performs better and looks great. The effort gives your slab longevity, safety, and style.
FAQs About Broom Finishing Concrete
What kind of broom should I use?
You should use a broom with thick, stiff synthetic or natural bristles. Nylon or horsehair are ideal materials. The broom head should be wide enough to imprint substantial areas.
When is the right time to broom-finish?
The right time to broom-finish is when the wet concrete has firmed up enough to walk on without leaving footprints. Press your thumb into the surface. If it leaves an imprint, wait longer until the slab firms up.
What's the proper technique for broom-finishing?
The proper technique for broom-finishing is using even, consistent strokes and moderate downward pressure as you drag the broom. Slightly overlapping the strokes ensures full coverage. Move in the same direction across the whole slab or section.
Can I apply color or stains to my broom finish?
You can apply colored concrete and color hardeners to accentuate broom designs. Acid stains can also add color after finishing. Always follow manufacturer instructions.
How long does a broom finish last?
With periodic maintenance like re-sealing, a broom finish can last 20 to 30 years or longer. Avoid heavy traffic and chemical exposure to maximize life span. Proper installation is key.
How do I clean and care for a broom finish?
Clean your broom finish with regular brushes from a stiff broom. Hose down the slab occasionally to prevent dirt buildup in imprints. Re-apply cure and seal products every few years. Make repairs quickly to avoid cracking or erosion.
Can I broom finish stamped or stenciled concrete?
Yes, adding a light broom finish creates a subtle texture across stamped and stenciled designs. Use a soft broom to avoid damaging detailed patterns.
What kind of sealer should I apply to a broom finish?
Use a penetrating acrylic or urethane-based cure-and-seal product meant for broomed concrete. The product will enhance color and impart lasting protection without altering texture.
How soon can I walk on newly broom-finished concrete?
Allow the concrete to fully cure for several days before heavy foot traffic. Avoid vehicles, furniture, or harsh chemicals until the concrete has hardened completely.
