A bush hammer is a floor grinder machine attachment used for surface preparation on concrete, asphalt, stone, and other masonry materials, consisting of a shaft or roller with a head or reel of hardened pins, teeth, or blades – these roughen up and texture surfaces as they roll or rotate across it.
Bush hammers prepare surfaces for new coatings and provide decorative textures with a standard floor grinder - no extra equipment is required. Our article covering how bush hammers work offers more information.
So What?
Getting the right surface texture for decorative or safety purposes can be a real headache with traditional surface finishing methods. You know the story - inconsistent swirling patterns that need extensive reworking to get things uniform again.
That's where bush hammers come in. These handy tools remove all the frustration from resurfacing with their engineered precision components. Swap out the cylindrical tungsten tipped reels to dial in precisely the finish your project needs, whether it's smooth as glass concrete or non-slip grip on roadways.
Range of Textures and Finishes
The interchangeable reels on bush hammers allow for tailored surface textures. From smooth concrete suitable for coatings to highly aggressive grip on roadways, bush hammers can achieve the perfect finish according to CSP levels set by the International Concrete Repair Institute.
Fine textured reels with small pins produce smooth, consistent concrete at a CSP 2-3 level. Medium textured reels are well suited for general surface preparation applications.
Meanwhile, coarse reels with large pins can remove coating layers over 10mm thick and maximise road skid resistance.
Bush Hammer Industrial Floor Refurbishment
Bush hammers efficiently strip and prepare concrete floors for new industrial coatings and toppings. They remove laitance, old paints, or epoxies, expose decorative aggregate, and level out uneven bars or joints on warehouse and factory floors, helping prepare the slab for durable and attractive new flooring solutions.
Compared to other surface preparation methods, bush hammers create ideal concrete profiles without deep scarring or an uneven finish – just specify the correct tipped reel for the job, such as the Blue Line 3-15 for CSP Level 5 texture.
The consistent performance, durability, and versatility of bush hammers make them indispensable for surface preparation across various industries. Their specialised engineering delivers the desired texture and renewal of worn infrastructure and flooring.
Summing Up
The industry has struggled to get quality, uniform textures from old hammerheads fitted to grinders for years. Sure, they could get the job done, but consistent finishes were rare, requiring extreme skill and time to get right.
Engineering ingenuity has finally cracked the bush hammer code. By combining precision components like tungsten carbide tips with optimised housing, we have a new system designed specifically for high-performance floor machines.
Contractors who've tested these new bush hammers report smooth, swirl-free concrete textures surpassing anything they could produce before.
The improved vibration absorption makes running them comfortable even for full workdays (note that the floor grinding machine also plays a role in vibration), and dust-free operation keeps worksites cleaner.
