How To Use Diamond Pads To Prep A Floor For Polishing

About This Project

Concrete Polishing Diamond Pads can be some of the most useful tools in your arsenal when finishing your concrete floors.


This is because they prep your floor in a way where the Stain or Polish or Epoxy (really whatever it is you are using) will catch onto the concrete in a way that makes it shine the way you want it to.

How To Prep A Concrete Floor For Polishing With Diamond Pads


Not to mention, when you pass through on a concrete slab, it’s going to do wonders at removing the dirt off the floor. Just check out Video #1 above.


Here we use a 50 grit Concrete DNA Diamond Satellite Pad which does a great job at removing the dirt off the floor, in just one pass.


In the video Toby simply puts a Diamond Pad on a concrete grinder and moves over the area slowly, applying a lot of water as he goes. Note: the link before does not lead to the same grinder as used in the video but it will achieve the same result.


Now you might be asking yourself, what exactly are we doing here?


Like why is it important to be using diamond tooling to prep the floor for polishing?


Well to begin, it removes the dirt from a dirty floor. And it does it better than any broom could.


Take the projects we are polishing in our videos for example: these are usually shops or other areas that have had high amounts of foot traffic. Not to mention, they’ve rarely been cleaned before we took the diamond tooling over them.


The dirt has already settled and become more integrated into the concrete. Well, this is going to take more to remove than a simple sweet through! Diamonds are excellent at this.


Now, let’s talk about the theory behind using Diamond Tooling. If you will refer to the 2nd video, this will make even more sense.


At a microscopic level, concrete has all these little peaks and valleys that we don’t see. When light hits these, it reflects in a certain way that makes it less shiny.


That’s not what we are aiming for. We want a nice, smooth surface that’s going to cause the light to reflect off the surface at the appropriate angle, and make it have that shiny surface feel we are aiming for.


This is also why we are going over the surface slowly, we want to make sure we get the surface completely covered.


Now, once you’ve made a pass (i.e. half the distance to the wall or so) get your double foam squeegee and push it the direction in which you are moving. You can also reuse the water as you need it, until it gets too dirty to use.

How To Install Diamond Pads On The Concrete Grinder


This section is referring to the 3rd video, where we place a Diamond Pad on a low speed floor buffer. By low speed we mean somewhere between 175 – 350 RPMs.


Most of these machines will be between 17-20 inch pads, and you use a Satellite Pad on them. And if you watch the video you’ll see how easy it is to get the pads on.


Essentially, the bottom of the machine will have a pad on them already that has little teeth all over the surface. This is going to grip onto the top of your Diamond Pad and make it easy for you to make passes with it.


After you do this enough times you can even run it with one hand!


Don’t skip the 4th video above, by the way. It’s a great walk through of all the different grits for the DNA Pads.


As you’ve seen, polishing floor with a Concrete DNA Pad is easy, and you shouldn’t have any issues with it. But if you do, leave a comment or get in touch and we’ll get back to you!

These videos use our Concrete DNA Diamond Pads, which you can find at the link below.
