30 GRIT GRINDING DIAMOND DISCS

Get the right finish from your concrete grinding job with 30 grit diamond grinding discs, designed for coarse grinding and concrete surface preparation. These diamond discs are ideal for removing surface imperfections, opening up concrete and preparing floors for subsequent grinding, polishing or coating applications.

Available from MEHCO in Mackay, our diamond grinding discs are a practical choice for contractors, builders, concreters and DIY users working on concrete floors and other suitable masonry surfaces.

30 Grit Diamond Disc for Concrete Grinding

A 30 grit diamond disc is commonly used as an initial grinding step when preparing a concrete surface. The relatively coarse diamond grit provides effective material removal while creating a suitable surface for progressing to finer grinding stages.

Depending on the condition and hardness of the concrete, 30 grit diamonds can be used to:

• Grind and prepare concrete floors
• Remove surface imperfections and minor high spots
• Open the surface of concrete
• Prepare concrete for polishing
• Prepare floors for coatings and sealers
• Remove surface residues and suitable coatings
• Level uneven areas before finer grinding
• Provide an effective first stage in a multi-step grinding process

The correct diamond tooling depends on the concrete hardness, existing surface condition and finish required. For particularly hard or soft concrete, a different diamond bond may provide better cutting performance.

Why Choose 30 Grit Diamond Grinding Discs?

Coarse grinding performance

The 30 grit size is suited to the early stages of concrete grinding where more material needs to be removed.

Ideal for surface preparation

Use 30 grit diamonds to prepare a concrete surface before progressing to finer grit sizes.

Suitable for grinding and polishing systems

A 30 grit disc can form part of a multi-stage concrete grinding and polishing process, followed by progressively finer diamond tooling.

Professional results

Using the appropriate diamond grit for each stage of the job can help improve productivity and produce a more consistent finished surface.

When Should You Use a 30 Grit Diamond Disc?

For many concrete grinding applications, 30 grit is used as a coarse preparation grit before moving to finer tooling. The exact starting grit will depend on the condition of the floor and the amount of material that needs to be removed.

If the goal is to expose aggregate, remove surface imperfections or prepare a floor for further grinding, a coarse diamond such as 30 grit can be an effective starting point. Once the required level of grinding has been achieved, progressively finer grits can be used to refine the surface.

For best results, select your diamond tooling based on the concrete hardness, required finish and type of material being removed.
