Polished Concrete – General
There are basic 2 parts. Exposure + Polish
There are different methods used depending on the look / exposure you are after. Saying this nearly all the different methods follow the same initial few steps.
Your diamonds need to match the concrete condition.
Hard concrete is a function of grind ability. If dust produced is exeptionally fine it wont keep the diamonds open.
Soft concrete produces coarse, abrasive dust, especially green, water damaged concrete.
If the concrete is hard then you will need to use GTA soft bond diamond tooling. If concrete is soft, you have to use a GTA hard bond diamond. At GTA we can help you with this.
The condition of the concrete will determine the initial grinding steps needed to prepare the floor for polishing including coatings, epoxy removal etc.
Note the lower the grit number, the larger the grit is. This sait the first cut you can start with a GTA 30 grit diamond then move up to the GTA 60 grit and final cut using the GTA120 grit.
To complete the polishing stage you would move onto the GTA polishing pads.
When to go to site
Brand new concrete floors you have to allow at least 7-10 days to cure before the major part of the work commences. If the slab is old, you may need to check for pits and cracks, and then use the GTA 100 product to fill the holes.
Go back to finish the polishing process before skirting boards go on / plastering stage.
How much aggregate will show
If you are required to show aggregate, you have to grind/pass over the concrete more times. Full exposure you may need to pass over up to 5 times.
Grinding Wet or Dry
Most people use the dry process – it is faster and less messy but you will need a good vacuum to take care of the dust.
These can crack however not every joint cracks.
Expansion joints can be filled with K15.
With new slabs we suggest using long rods/rio bars in corners which can help reduce the cracking.
Have fun making money. Learn from others who are experienced in this business.
At GTA we can sit down with you after hours and help you start or help you move forward.
Thanks from all at GTA - Hope to see you in the near future
