A brushed concrete finish can be prepared by applying texture to freshly poured concrete with a stiff-bristled brush.
This method is frequently used for floors, driveways, patios, etc. In this process, the brush is dragged across the surface, creating patterns and grooves that give the surface a textured and appealing finish.
The brush used may affect the final result of concrete in different ways. Horsehair brushes are generally used to produce a smooth and polished texture, whereas wire brushes are preferred for a more pronounced and textured appearance.
By changing the pressure and direction of the brushstrokes, masons create a wide range of patterns and textures.
Brushed concrete finish not only looks good, but it also has useful benefits. The texture makes the surface durable and slip resistant. It is suitable for high-traffic areas.
The brushing method also helps to hide minor flaws that might appear during the pouring and finishing process of concrete.
Overall, Brushed concrete finish surfaces are popular for outdoor surfaces that need to be traction, durable, and beautiful to look good because they have benefits that are both useful and beautiful.
How to brush finish concrete | Procedure for Brushed concrete finish
1. Pour Concrete: Level the surface with a bull float or screed after the concrete has been poured on the surface. Remember that the concrete should be evenly distributed all over the surface. i.e. make the thickness of concrete equal.
2. Curing of concrete: The concrete should be left to cure for at least 24 hours. The concrete will be sturdy enough to withstand brushing if this is done.
3. Make the surface wet: Before brushing, wet the surface of the concrete with fresh water. This keeps the concrete from drying out too quickly and makes it easier to draw texture on concrete.
6. Pick the proper brush: Choose a brush with stiff bristles that are suitable for the required texture. Wire brushes are generally used To draw texture on concrete surfaces.
Make sure that the brush should be clean, has a good shape, and is free from any dirt and curved bristles.
7. Start Brushing: First of all work over the wet concrete surface in small sections. Hold the brush at a slight angle and maintain consistent pressure while dragging it across the surface.
The brushstrokes must overlap in order to create a textured pattern. Keep the pressure and direction of the brush constant throughout the concrete surface.
10. Modify the texture: To create various textures, you can change the depth and direction of the brush strokes. Heavier strokes result in deeper grooves and a rougher texture while lighter strokes produce a smoother finish. You can use any method according to your choice and requirement.
11. Clean the surface: Use a broom or blower to remove any bristles or loose debris from the surface after brushing is finished.
13. Allow the brushed concrete to fully dry and cure it for 6 to 7 days to get maximum strength and durability.
14. You can use a curing compound. If there is a lack of water.
When to brush finish concrete?
Brushing on the concrete surface should be done while it is still soft and after the surface water has evaporated. This typically takes between 20 minutes to 4 hours, depending on the weather condition.
Brushing too late on the concrete surface makes it difficult to create an effective texture, whereas brushing too early can weaken the concrete.
Remember the following points while deciding to brush on finished concrete.
- Poke the concrete surface with your finger. If it makes an impression, it’s too soft.
- To determine texture, feel the pliability of the concrete. If it is flexible, it is ready for brushing. If something is rigid and hard, it is too late.
- The water above the surface of the concrete should be completely evaporated after casting.
Brushed concrete vs smooth
The two most common types of concrete finishes are Brushed concrete finish and smooth concrete finish. Each has its own advantages and disadvantages.
a. Brushed concrete finish
Brushed concrete is made by brushing freshly poured concrete. The surface becomes a pleasant appearance and a practical texture. It is safe to walk on in the rain due to the surface’s excellent grip and texture.
Brushed concrete finish is constructed in places where people walk a lot, like driveways, patios, and sidewalks. Maintaining brushed concrete requires little effort.
b. Smooth Surface
A smooth concrete surface is constructed using a steel trowel on freshly poured concrete. It makes the surface smooth and polished, making it simple to clean and maintain.
Smooth concrete is generally used in commercial and industrial buildings, where a polished appearance is desired.
Brushed concrete vs smooth
|Feature||Brushed concrete finish||Smooth Concrete|
|1. Texture||It has lower traction than a brushed concrete surface.||It has a textured surface|
|2. Traction||It has Excellent slip resistance||It has a Polished surface so, It has poor slip resistance|
|3.Appearance||It looks Attractive||It has Polished surface and looks more attractive|
|4. Cost||Brushed concrete finish is less expensive||More expensive|
Which type of concrete finish is right for you?
Your specific requirements and preferences will determine the concrete finish that works best for you.
A brushed concrete finish is an excellent choice if you want a surface that is safe, beautiful, and requires little upkeep. Smooth concrete is a great option if you want a polished surface that is spotless and easy to clean.
Broom vs brush finish concrete
|Criteria||Broom Finish Concrete||Brushed concrete finish|
|1. Texture||It has Coarse texture with visible broom lines||It has a Coarse texture with visible broom lines|
|2. Slip-resistance||It has Excellent traction so, it is suitable for areas where slip resistance is important||It Varies depending on the texture created on the surface|
|3. Durability||It is Highly durable and can withstand heavy foot traffic and vehicular loads||It is also Durable, but may not be as resistant to wear as a broom finish|
|4. Aesthetics||It provides the more functional, utilitarian appearance||It looks more attractive than broom-finish concrete.|
|5. Customization||It has Limited customization options||Can create different levels of texture on the surface|
|6. Application||It is suitable for outdoor areas like driveways, walkways, and pool decks||A brushed concrete finish is suitable for indoor applications and decorative concrete elements|
|7. Cost-effectiveness||More cost-effective due to minimal tools and labor required||May require more labor and expertise, potentially adding to the cost|
|8. Speed of completion||It can be completed relatively quickly||It may take longer due to detailing and customization|
|9. Primary Considerations||It is generally constructed for slip-resistance||It is generally constructed for visual appeal and customization options|
