RAIZI shows the detailed process step by step to follow while doing dry cement terrazzo grinding and polishing.


This is an initial rough cement terrazzo floor surface installed 30 days ago.


 
Now let’s begin:
Step 1
Husqvarna PG820 floor grinder machine ready: Use GP Gold Series metal bond #30 for the surface opening. Usually this is a challenge for most polished concrete contractors. Your metal bond diamond segments have to be very sharp but also own consistent cutting
performance in dry use. As you know, the cement terrazzo flooris very hard C30 usually but very sticky. This is the reason why I sayit is a challenge.If people have no good diamond tools, they usually open the surface with water. This wet grinding process will generate too much slurry.It will cost much more time and money in dealing with the slurry. So dry solution is better choice.


 
Some people may ask why not open the surface with #16 metal diamonds, it is much faster. I would like to say that very very deep
scratches will appear once you use #16 metal diamonds. It will add your time cost in removing such deep scratches with coming metal diamonds. Many people use #16 diamonds segments or wet grinding way to open surface and leveling the cement terrazzo floor
because they cannot get REALLY GOOD diamond system.

Let us check the scratches depth generated by #16 metal diamonds

Note:
Cement Terrazzo uses a cement matrix and describes multiple terrazzo systems including sand cushion, bonded, monolithic,
polyacrylate, and rustic. These floors use a cement-based mix with the aggregate (chips) to form the terrazzo top.


 
Keep grinding 3-5 passes over the floor surface, dry working to get a heavily exposed aggregate.

Step 2
Use Redi-lock two button metal bond diamond segment #50 to remove the scratches left by metal#30 and level the concrete surface slowly and evenly ,dry working for 3-5 passes over the floor surface.


 
Step 3
Let us go to the transition steps. It is the most important stage from metal bond to resin bond because scratches removal is concerned. The longer the metal bond diamonds are used, the more chance scratches will appear on the floor in grinding steps.
Now you have the MAGIC tools for scratches removal. We call it SharpCut ceramics.  with this SharpCut ceramics, you speed up your working efficiency and shorten the working time. This is to say, you have saved the money.

Use 3 inch #50 SharpCut™ ceramic polishing pads for transition

Step 4
Apply Pore Filler on the floor and grout with the #100 SharpEco™ diamond ceramic polishing pads to fill the pores created by air bubbles and extracted aggregate. The pore filler will combine the dust and will be forced into the holes tightly.

Please note:

Step 5
Use the NHD hybrid diamond polishing pads #100, dry working, go through 2-3 passes,We come to the polishing step now. So before start polishing process with resin bond, use the mops ,sweeper and vacuum cleaner to wipe off all the dust scattered on the floor and also carefully clean the dust and small sand aggregate on plate of the concrete grinding machine. It is very important to avoid new random scratches because of sands and falling diamonds.


And the effect as follows:



Step 6
Use the NHD hybrid resin polishing pads #200, dry working, go through 2 passes




The effect is as below:



Step 7
Use the hybrid resin polishing pads #400, dry working, go through 2 passes




And the effect after #400 is as below, you can notice that slight sheen has been available on the floor surface.



Step 8
Use the hybrid resin polishing pads #800, dry working, go through 2 passes


The effect is as below, you can see that gloss has been shown on the floor. The floor has been highly polished. Objects reflected are
sharp and crisp with mirror like clarity.



Step 9
Use the hybrid resin polishing pads #1500, dry working, go through 2 passes


The effect is as below,1500 grit diamond pads result in a surface that shows a high level of specular reflectivity and the most mirror-like surface. Once floor is polished to a 1500 grit level, the Effiman Polished Concrete System finish delivers a high level of gloss.



Step 10
Use the hybrid resin polishing pads #3000, dry working, go through 2 passes


The effect is as below. So you can see that we got the perfect fully mirror like finish on the cement terrazzo floor. It can be as the premium floor for museum, art gallery, library and luxury store.
