Diamond Polished Concrete.
There is no substitute for a true Diamond Polished Concrete floor.
A DPC Diamond Polished Concrete floor will out perform and outlast any other flooring system, with the exception of a floor that is subject to strong chemical abuse. In such cases we recommend our Syncoat Epoxy systems.
Consider these facts (most relevant to our commercial, industrial and retail customers)
- Most floors that are to be coated will require diamond grinding anyway.
- When an epoxy coated floor fails, the residue need to be ground off (cost $x) and then reapplication is at the original full cost again (+ inflation). While the initial cost of a Diamond Polished Concrete floor may be equal to a high build epoxy flooring system, the lifecycle cost can be 50% or lower after 10 Years.
- If in 10 or 15 years a Diamond Polished Concrete floor needs to be restored, only the last few polishing passes need to be redone. And often it is only in the high traffic areas. The restored areas will blend with the rest of the floor, because it is the same concrete.
- A Diamond Polished Concrete floor will be much flatter than a coated floor. This is because we use Planetary Diamond Grinders that grind off the high points in the floor. The result is a floor that will evenly bear weight loads. This reduces premature wear on high points of the floor and stress on equipment such as fork hoists from moving loads.
- Our Diamond Polished Concrete floors are treated with a densifier. This not only hardens the concrete, but prevents dusting from the concrete. The advantage is that there is less clean up, stock in warehouses is not covered with dust and staff have a cleaner environment to work in.
- A Diamond Polished Concrete floor has good light reflection. When used in conjunction with clear roof panels, it can in some situations, eliminate the need to have any lights on (during the day only). In other situations it typically reduces lighting costs by 50% or more. A concrete floor Diamond Polished to 3000 grit will reflect approx 50% of the light it receives. These savings all adds $ to the profit of the business.
- A Diamond Polished Concrete floor is easy to maintain. The very smooth surface prevents substances from easily bonding to the surface. The floors can be easily swept by hand or by mechanical means. Where required auto scrubbers can also be used.
- Surprisingly, a Diamond Polished Concrete floor is not slippery, and in fact a wet floor has more slip resistance than a dry floor. This is due to the tension the floor creates on water droplets. Where a fully sealed or coated floor will cause the water droplets to have a round bottom and cause aqua planning (the droplets roll across the surface), Diamond polished concrete allows the droplets to conform to the surface and prevents aqua planning.
- The process of creating a Diamond Polished Concrete floor does not involve using any flammable, dangerous or harmful chemicals. This system is both environmentally and physiologically safe.
- There is very little down time when creating a Diamond Polished Concrete floor. There is no drying time where the floor can not be traversed if required (some epoxies can be up to 5 days) and you do not have to be mindful of foreign objects that may get stuck in the product. There is no climatic delays and the process is not extended in winter. We do however prefer to have clear access to the area being completed.
How does the system work?
Our DPC Diamond Polished Concrete system utilises, and improves your existing or purpose laid concrete floor.
Step one - We start with aggressive diamonds and remove the concrete paste. This stage also removes the high points of the floor creating a flat surface. This stage takes the longest as we need to remove up to 5mm of concrete. This leaves deep scratches in the surface.
Step two - Semi aggressive diamond discs are used to remove the deep scratches created in step one.
Step three - An even finer diamond grade is used to remove the scratches left by step two.
Step four - We slurry coat the floor to fill aeration holes in the concrete.(many companies don't do this an end up with an inferior finish)
Step five - the slurry coat is removed.
Step six - the densfier is applied, this hardens the concrete and prevents dusting.
Step seven - the final metal bond diamond grade is used to remove any densifier residue and remove the scratches left by step 5.
Step eight - resin bonded diamond discs are used to remove the scratches left by step seven.
Step nine - finer resin bonded diamond discs are used to start bringing clarity to the floor.
Step ten - Even finer resin bonded diamond discs are used to bring gloss to the floor.
Step eleven - The floor is finished with a coat of Creteshield SR. This is a stain resistor that helps protect the floor from oils, fats and many other contaminates. It also increases the slip resistance of the floor.
Depending on the concrete, how it was laid and many other variables, up to 12 or 13 grades of diamonds may need to be used to create a glossy Diamond Polished Concrete floor.
