An Overview

Polished Concrete is a remarkable flooring solution that combines cutting-edge technologies to enhance the appearance and durability of concrete surfaces. Through advancements in floor grinding machines, chemical treatments, and resin diamond technologies, we can now achieve stunning high-grade finishes with exceptional wear resistance.

What is Polished Concrete

Polished Concrete is the combination of three different technologies applied to a concrete surface. By combining advancements in floor grinding machines, chemicals and the latest resin diamond technologies, we are now able to produce spectacular high grade surface finishes with wearing properties unlike any other.

The CGP Polished Concrete Process

To begin the CGP Polished Concrete process, it is essential to allow the newly laid concrete slab to cure for a period of 7-28 days. For new developments, we recommend grinding the slab before any construction commences. This approach ensures a uniformly flat surface throughout. During this stage, customer presence is required to approve the desired level of aggregate exposure. If construction has already begun or it is an existing house, we prefer to complete skirting board installation, joinery work, and final coats of painting after we finish our process, unless the painting is already completed.
The Stages:
1. Coarse Grinding (30 Grit): This stage exposes the desired amount of aggregate and ensures overall flatness, satisfying the customer's expectations.
2. Medium Grinding (60 Grit): The use of this grit removes any scratches left behind by the 30 grit process.
3. Fine Grinding (120 Grit) and Grouting: In this stage, we utilize dust from the concrete along with a grout agent to fill in imperfections like cracks and holes throughout the floor.
4. Application of Densifier/Hardener: A state-of-the-art densifier/hardener is applied, reacting with the concrete to create an incredibly hard surface.
5. Secondary Application of Hardener and Removal: The next day, we apply another coat of hardener to further enhance the surface, and then remove it using 50 grit resin pads.
6. Additional Application of Hardener: Another coat of hardener is applied and allowed to dry.
7. Removal of Hardener: Using 100 grit resin pads, we remove the hardener from the surface.
8. Further Application of Hardener: A subsequent coat of hardener is applied.
9. Final Removal of Hardener: With the use of 200 grit resin pads, we remove the hardener completely.
10. Polishing with 400 Grit Resin Pads: This stage achieves a matte finish.
11. Polishing with 800 Grit Resin Pads: A satin finish is achieved.
12. Polishing with 1500 Grit Resin Pads.
13. Polishing with 3000 Grit Resin Pads: A full gloss finish is achieved.
14. Application of Impregnating Sealer/Enhancer: We apply a state-of-the-art sealer/enhancer designed to protect the concrete surface from stains, fats, oils, while enhancing its natural color.
15. Buffing off Excess Enhancer: The excess enhancer is carefully buffed off, leaving a beautifully finished floor.
Once this stage is completed, your floor is ready to use. At CGP, we use only the best machinery, diamond tooling, and polishing pads available on the market, ensuring the highest quality results.

Benefits of Polished Concrete

When properly installed, treated, and maintained, Polished Concrete offers numerous advantages. These include:
- Wear - Dusting - Tyre marking - Water, Industrial Chemicals, Oils, Food stains, Greases, Hydraulic fluids, Fuels, Fatty materials - Abrasion & Heat - Low maintenance surface without surface coating - Improve natural lighting - Allege free - The process in which the concrete is ground and honed using specialized diamond bonds and chemical treatments (Densifier and Hardener) provides the durability and strength of up to 10 times that of a standard polished concrete surface. - With Polished Concrete or mechanically polished concrete, we are taking one of the hardest materials known to man (concrete) and making this the wearing surface instead of film coating/sealer. - Polished Concrete can be used in new or old construction for manufacturing, warehouses, automotive factories and showrooms, retail, commercial and domestic environments. - Polished Concrete can be installed without costly down time normally associated with epoxy and urethane coatings. - Polished Concrete brings out the beauty of concrete and combines it with the unparalleled advantages of an easy maintenance. It eliminates the need for epoxy or thin film coatings will improve over age guaranteeing a surface that can withstand even the toughest traffic and add years to the expected life of the floor. - Additional benefits of the Polished Concrete system include its odorless application and environmentally friendly properties (VOC free) promoting a healthier working environment with no immediate or continual toxic emissions. - Resistance to wear, dusting, tire marking, water, industrial chemicals, oils, food stains, greases, hydraulic fluids, fuels, and fatty materials. - High abrasion and heat resistance. - Low-maintenance surface without the need


- Always keep floor vacuumed and dirt free. - Spills should be cleaned from polish concrete surface immediately. - Do not use bleach or citrus based cleaners on the floor. - Furniture should have protective pads placed under them. - Micro fibre mop is best used to keep floor clean and streak free. - Areas where heavy soiling exists will require localised cleaning prior to cleaning entire Polished Concrete area. - In high traffic areas; burnish daily with a high speed burnisher using red nylon pads.

Frequently Asked Questions

Can you have coloured polished concrete floor?
Absolutely! When laying a new slab, you have the option to choose from different cement colors. Discuss your preferences with your concrete supplier to explore the available options.
Can I choose the aggregate for a new concrete slab?
Yes, you have the freedom to select various aggregate colors, types, sizes, and minerals for the topping mix when laying a new concrete slab. Discuss these options with your concrete supplier to determine the best choice for your project.
Is there an alternative to the exposed aggregate look?
Yes, the depth of the grind can result in different levels of stone or aggregate exposure, allowing you to achieve a non-exposed aggregate finish if desired.
Can you polish an existing concrete slab?
Absolutely! If you're tired of the old look of carpet or floorboards and want a fresh, contemporary, low-maintenance floor, we can polish the existing concrete slab. The final result will depend on factors such as the type of concrete, the slab's MPA (megapascal) rating, aggregate density, and the condition of the concrete floor.
What about 75-year-old concrete that is pitted, well-worn or has had coatings applied?
No problem! We can transform your worn-out concrete floor into a beautiful marble-like finish, giving it a fresh new look.
When should I liaise with a concrete polisher?
It's best to involve a concrete polisher at the earliest planning stage of your project. This allows for better coordination and potential cost benefits for the client.
Are there any harmful VOC’s?
No, the polishing process is completed in an eco-friendly manner, making it suitable for green construction projects. There are no harmful VOCs involved.
Is a polished concrete floor slippery for outdoors?
No, the surface can be made non-slip, making it suitable for outdoor areas such as pool decks and outdoor entertaining spaces.
How is it done?
Diamond discs are mounted to a heavy grinder weighing 200+ kilos. Rough grits are used to remove imperfections and flatten the floor, followed by finer grits to achieve a marble-like shine. The process typically involves 14 steps, starting with 30-grit diamond shoes and ending with 3000-grit resin diamond pads.
How long will it last?
Polished concrete is a permanent solution. Unlike wax, epoxy, or acrylic coatings that may eventually fail, our process results in a bare concrete floor that has been permanently polished. In heavy industrial, commercial, or institutional use, a cost-effective re-polishing may be needed years down the road, depending on your maintenance practices.
Can the shine be destroyed?
While it's not easy to do so, strong acids such as muriatic acid can etch the floor and destroy the shine. However, etched areas are easily repaired.
Is the process dusty or messy?
No, our state-of-the-art equipment minimizes dust during the polishing process, making it almost dust-free.
Where is Polished Concrete found?
Polished concrete can be found in a variety of spaces, including warehouses, restaurants, schools, retail stores, manufacturing facilities, residential properties, showrooms, and many more applications. Its versatility makes it suitable for various environments.
