Quick Answer

A bush hammer plate uses rows of hardened pins that strike the surface thousands of times per minute to fracture, texture and profile concrete and stone. Use it for anti-slip texture, breaking down thick coatings, and preparing floors before overlays or new coatings.

How It Works

Unlike a grinding disc that cuts with diamond segments, a bush hammer plate works by percussion. The pins impact the surface and shatter the top layer, which is exactly what you need for rough texture or brittle coatings.

When to Use a Bush Hammer Plate

• Anti-slip safety texture on walkways and ramps
• Removing glue, varnish and resin coatings
• Breaking thick coatings that resist diamond grinding
• Face-see and orange-peel effects on precast panels
• Scarifying before new coatings or overlays

Bush Hammer vs Grinding Disc

• Bush hammer: textures and breaks brittle layers fast, leaves rough profile
• Grinding disc: removes material smoothly, refines the profile
• Typical combo: bush hammer first, then grind to smooth

Machine Options

Bush hammer tooling comes as plates for floor grinders (230-270 mm) and smaller plates for angle grinders (125 mm). Roller-style heads are popular for floor machines because the rotating rollers cover a wide path efficiently.

Frequently Asked Questions

Q: Does bush hammering weaken the concrete?

A>No. It removes a thin surface layer; depth is controlled by pin design and machine pressure.

Q: Can I use it on soft concrete?

A>Yes, but reduce pressure - the pins can chip soft slabs more aggressively.

Q: Do I still need to grind after bush hammering?

A>Only if the job needs a smoother profile, for example before coating or polishing.

Conclusion

Bush hammer plates are the fastest way to texture and de-coat concrete. Keep them in your toolkit for anti-slip work and coating breakdown, and follow with grinding when the finish must be smooth.
