Large 3 Headed Concrete Grinder

1. Can you grind concrete?
Yes, many people grind concrete in order to either remove high spots in that have been laid in a slab, soften edges in either sharp or raised concrete, smooth over or remove old adhesives for the purpose of repainting, or simple grind and polish the concrete slab for an aesthetically pleasing finish. The process of concrete grinding is simple and easy, watch one of our instructional videos, or ask one of our staff in-store.

2. Is concrete grinding difficult?
No, the process itself of grinding concrete is relatively simple, with any handy DIY individual being up to the job. However, it is important to make sure that you have the right tool for the job, whether that be grinding concrete to expose the aggregate, removing old paint, polishing the concretes surface, scarifying to remove volume or simply to shape and/or edge a corner, being provided with the right machine and the right grinding attachments will make a world of difference.

3. How much does it cost to hire/rent a concrete grinder?
The price of a concrete grinder will vary depending upon the price of the machine and the duration over which you rent/hire it. Starting from a small hand-held concrete edger, the price is $130 per day & $500 per week, however, this is only appropriate for small jobs; compare this a single head concrete grinder, which is $195 per day, $700 per week, but is capable of grinding up to 80 square meters. Finally, a large 3-headed planetary concrete grinder is best used for areas above 80m2, and this costs $400 per day and $1500 per week.

4. How do I choose which grinding pads I require?
The best and easiest way to determine the required grinding pads is to either look at the linked PDF file titled “concrete blade selection chart” across any concrete grinding product or to watch our linked video on how to choose concrete grinding pads. Failing this, feel free to call in and talk to one of our helpful staff members.

5. What tool should I use to smooth concrete?
There are many tools that can be used to smooth concrete, organized by size, the first is a concrete surfacer/ edger, used to edge the sides of a slab, or smooth over rough edges of a protruding slab, the secondly is a single head concrete grinder, used to either grind or polish concrete in areas below 8m2. The third tool for smoothing concrete is a large 3-head planetary concrete grinder, which is the industrialized version of the small concrete grinder, appropriate for sizing above 80m2. Finally, if you are looking to remove a large amount of volume, a concrete scarifier is best, which utilizes hardened spinning rods to plain down the concrete in layers.

6. Do we charge for wear on the grinding pads?
Yes, this pricing will vary between machines and can be enquired about with our customer service team. The total charge is taken as a deposit, with the remaining diamond being refunded back at the conclusion of the hire.
