TYPES OF CONCRETE GRINDERS AND THEIR PRIMARY FUNCTIONS

For minor and major projects that involve concrete, grinding the material could become a very serious issue. However, contractors that render these services use different machines and one of them is concrete grinder. 

But the selection of this machine depends upon the size of the project and thus, you can choose from different versions that we have discussed here in this post.

These concrete grinders are broadly classified into three names like hand-held, walk-behind and then, the last one is the ride-on concrete grinders. Let us have a look at these names and their features.

Hand-Held Concrete Floor Grinders -

• According to the experts, these hand-held units are ideal for smaller applications and for fiddly jobs like grinding areas that are close to walls, in corners and other hard-to-reach places.  

• They have very compact size and because of this, they are very light in weight and hence, very easy to manoeuvre.

• Because of these features, they are an ideal choice for domestic projects like smoothing concrete countertops, bathroom floors and rough patches on concrete floors.

• Other than this, these hand-held concrete grinders are also ideal for smoothing vertical surfaces like walls and door jambs.

• However, they are hand held, you will have to control it manually and with this, you will achieve really soft surface.

Walk-Behind Concrete Floor Grinders-

• The next version is given the name of "Walk-Behind Concrete Grinders" that come in various sizes ranging from single disc units right up to multiple disc units.

• Because they are very easy to manoeuvre, it can be used for polishing larger surface areas and even concrete floors both in domestic as well commercial areas.

• Another point to note is that they are well-suited for profiling large slab surfaces in a relatively short space of time and are a very popular choice in even amongst first-time users.

• The "Walk-Behind Concrete Grinders" is categorised in terms of size, i.e. small, medium and large and all of them are greatly helpful in grinding the concrete.

Solvent Borne Epoxy:

• Experts say that this material is the traditional version that has been in since this material was used for the first time.

• A very notable characteristic of this material is that it is mixed with a relatively higher amount of organic a compound called "solvent" that dries up when the epoxy is applied.

• As a result of drying, the epoxy floor coating Sydney dries up, leaving behind a really robust and durable surface.

• This type has a number of advantages and there are some controversies too, attached to it.

• One more meaning of this name is that it uses water as the main carrier and there are no solvents included at all.

• At the same time, ease of application is something that you need to take note of and with it; thin and thick coats can be applied without strenuous efforts.

• As far as cleaning is concerned, you would be surprised to know that it requires just water in order to be cleaned up.

• Despite all the qualities and positives that we discussed you need to understand that this version too has its share of drawbacks, but they are not as serious as those present in solvent-based epoxy.

• Because this is pure epoxy, it is given the name of 100 percent epoxy and the top thing to know is that it puts not environmental impacts whatsoever.
