What is the 16 Grit Double Zig Zag Redi Lock Grinding Shoe used for?
It is designed for aggressive initial concrete grinding and surface preparation. The coarse 16 grit is suitable for removing surface imperfections, grinding high spots and preparing concrete for subsequent grinding, coating or polishing stages.

Which bond should I choose?
Choose the bond according to the hardness and abrasiveness of the concrete. As a general rule, use a softer bond on harder concrete and a harder bond on softer or more abrasive concrete.

When should I use Super Soft Bond?
Super Soft Bond is recommended for very hard, dense or high-MPa concrete where harder bonds may glaze and stop exposing fresh diamond effectively.

When should I use Soft Bond?
Soft Bond is designed for hard concrete and helps continually expose fresh diamond during grinding.

When should I use Medium Bond?
Medium Bond is a versatile general-purpose option for medium or normal concrete hardness.

When should I use Hard Bond?
Hard Bond is recommended for soft, porous or abrasive concrete. The harder matrix helps prevent the diamond segments from wearing too quickly.

How high are the diamond segments?
The Double Zig Zag grinding shoe features 12mm high diamond segments for excellent usable segment depth and long working life.

Is 16 Grit aggressive?
Yes. 16 Grit is a very aggressive metal-bond diamond grit designed for initial grinding and fast material removal. It will leave a coarse scratch pattern, so finer grinding stages may be required afterwards depending on the desired finish.

What machines are these grinding shoes compatible with?
They use the Redi Lock mounting system and are designed for compatible Husqvarna Redi Lock floor grinders. They can also be used with other floor grinding machines fitted with a suitable Redi Lock adapter or conversion plate.

What happens if I choose the wrong bond?
A bond that is too hard for the concrete may glaze and stop cutting effectively. A bond that is too soft for abrasive concrete may wear prematurely. Selecting the correct bond helps maximise both cutting performance and tool life.
