Selecting proper Concrete Polishing Pad (or disc) is the key to obtaining a decent finish for your concrete and obtaining the foremost bang for your buck. There are many alternative sources, names, designs and costs for diamond pads in the market. This could be terribly confusing, and what usually happens is that our choice comes all the way down to value. This is unfortunate because in several cases an inexpensive pad can cost you a lot within the long-standing time. However, no one is asking you to shell out a large unwanted sum of money for these pads! There’s a place for those, and we don’t have to be compelled to go there (granite people may though).
The large diameter pads are stable on big and flat areas in comparison to the smaller pads. But, the large pads cannot stay stable on the thin concrete areas. In addition, you will have trouble in using them on the vertical edge of the kitchen counters.
Small diameter pads are less stable and a lot possible to gouge if used on big polishing machines. These are suitable for small machines and do a great job on small edges and strips of concretes where a large polishing pad won’t work properly.
Diamond pads are available in a wide range of thicknesses, from around 2mm skinny to 8mm thick.
Thicker pads can last longer, however, they tend to be much stiffer, and generally are susceptible to cave in when not dried or used for a long time.
Thin pads don’t last as long, however, they are versatile. This is often a giant advantage when you are polishing curved surfaces such as wash basins.
#3. Diamond Quality:
While it’s simple to determine the thickness of a concrete polishing pad, it’s not that easy to assess the quality of the diamonds embedded in the pad, or for that matter, even the grading and quantity of diamonds can’t be assessed that easily. Ultimately it’s the diamonds that do the cutting, and they are the reason for the cost of the polishing pads.
The most expensive concrete polishing pads always use the top quality industrial diamonds. In these pads, the diamond concentration is high, and therefore the gradation is slim. Diamonds are available in a range of sizes. A slim gradation means that most of the diamonds are of equal size and that the grit range of the disc is a lot more precise. Any change in the small diamonds never has any effect on the standard of the concrete surface.
Cheap pads use low-grade diamonds. These tend to possess a lot of flaws and have a far poorer graduation. Additionally, fewer diamonds are embedded in such pads. Mostly the gradation in such concrete polishing pads is broader, thus one pad may have a significant amount of smaller diamonds and a few coarser diamonds. This ends up in a low-quality surface and slower cutting.
#4. Binder used for the pads:
The binder that encapsulates the diamonds is simply as vital as the diamonds, and it has a great impact on the functionality and the longevity of the concrete polishing pad. Binder materials vary from ceramic to organic compound, and different materials are used for different pads. Binder hardness is extremely vital. A binder that’s too soft can wear away quickly when used for polishing a hard surface such as concrete.
Nearly all wet sprucing pads use an organic compound binder with different kinds of resins. It’s terribly rare that a pad distributor will not be able to describe the binder with any purposeful detail, thus you have to make sure you ask the distributor about the binder used before selecting your concrete polishing pad.
