Haynes Polished Concrete is a concrete polishing company in Greendale near Melbourne in Victoria that can be contracted to provide concrete grinding and polishing for home that has an existing polished concrete floor. That’s right, we can come to your home and re-polish your existing concrete floors so they look like new again.

We call this type of service a regrind and polish of an existing polished concrete floor. For this home, the client had moved into the home a few years ago and even though the floor had been polished previously, it was showing signs of wear because it was done about 10 years ago without any other regular servicing or maintenance in between.

So we can visit your home to regrind the floor, which is the last grinding stage, then polish the floor to a high gloss sheen finish to make it look like new again. We can do this for large areas like living rooms, kitchen or dining areas, even hallways or bedrooms. For this home it was about 100 square meters of existing polished concrete floor that had to be treated. After masking up all the walls, benches or other items that would be in the way we could use our mechanical polished concrete machine or a mix of hand polishers to get into the tight areas like inside the pantry in the kitchen.

The budget required for this concrete grinding and mechanical polished concrete service was approximately $10,000 ex gst and it took around five days to complete because of the large area to be polished. As you will see in the photos the final result is like having a brand new polished concrete floor.

Can existing polished concrete floors get damaged or scratched?

Polished concrete floors are the toughest most durable material to use for flooring in a home, business or retail shop. Depending on the quality of the concrete polishing service that is used initially it is possible that it can get scratched and lose its lustre over time. If it was just a concrete grind and seal then depending on the quality of the sealants used these can wear away over the years. Similar scenario applies if it was a mechanically polished concrete floor which provides a harder wearing surface compared to one that is sealed but can be prone to aging over time.

Many factors will  contribute to this happening and these are the common causes of damage or scratches on existing polished concrete floors:

  1. Heavy foot traffic: High volumes of foot traffic, especially with abrasive or sharp objects like rocks or sand on shoes, can cause wear and tear on the surface of the floor, resulting in scratches. It is pretty similar to running soft sand paper over a surface, over time it just wears away. If your home has polished concrete floors near the entry / exit to the backyard then this can be common. Alternatively for a business with high foot traffic during the day this can have the same effect.

  2. Furniture movement: Dragging or sliding heavy furniture across a polished concrete floor without proper protection can lead to scratches or scuff marks. This could be chairs under a dinner table for example that are pulled in and out all the time without any feet protection.

  3. Impact or dropped objects: Dropping heavy objects or tools onto the floor can cause chips, cracks, or scratches, particularly if the impact is forceful or concentrated.

  4. Chemical spills: Certain chemicals, such as acidic or abrasive substances, can damage the surface of a polished concrete floor if not cleaned up promptly. Chemical spills can cause etching or discolouration, leaving visible marks.

  5. Improper maintenance: Using harsh cleaning agents, rough cleaning tools, or abrasive pads can contribute to scratching or dulling the surface of the floor. It is important to follow proper maintenance guidelines to minimise the risk of damage.

While polished concrete floors are durable and resistant to many types of damage, they are not completely impervious. Regular maintenance and taking precautions to prevent potential sources of damage can help extend the lifespan and appearance of the polished concrete floor. If damage or scratches do occur, regrinding and polishing can be considered to restore the floor to its original condition.

Why do you need to regrind an existing polished concrete floor?

Regrinding and polishing an existing polished concrete floor in Melbourne may be necessary under certain circumstances. Here are some common reasons for considering regrinding and polishing:

  1. Surface imperfections: Over time, polished concrete floors may develop scratches, stains, or wear due to heavy foot traffic, furniture movement, or other factors. Regrinding can help remove these imperfections and restore the floor’s smooth and even appearance.

  2. Levelling and flattening: Unevenness or uneven wear can occur in certain areas of a concrete floor. Regrinding can address these issues by levelling the surface and creating a consistent finish throughout the floor.

  3. Gloss enhancement: Polished concrete floors can lose their luster and shine over time due to regular use and exposure to dirt, grime, or chemicals. Regrinding followed by polishing can revive the floor’s gloss, making it look new and vibrant again.

  4. Changing design preferences: If you want to alter the appearance of your existing polished concrete floor, regrinding provides an opportunity to modify its exposure level, aggregate visibility, or even add decorative elements. This allows for customisation and adaptation to evolving design trends.

Benefits and considerations of regrinding and polishing:


  1. Cost-effective: Regrinding and polishing an existing floor is generally more cost-effective compared to installing a new flooring system. It saves on material and labor costs since the existing concrete slab serves as the base.

  2. Sustainability: By reusing the existing concrete slab, regrinding and polishing contribute to sustainable practices by reducing waste and minimising the need for additional resources.

  3. Improved durability: Polished concrete floors are known for their durability and long lifespan. Regrinding and polishing can strengthen the surface, enhancing its resistance to abrasion, impact, and stains.

  4. Low maintenance: Polished concrete floors are relatively easy to maintain. They require regular cleaning and occasional reapplication of a protective sealer. By regrinding and polishing, you can restore the floor’s low-maintenance characteristics.

  5. Aesthetics: Regrinding and polishing can enhance the appearance of your concrete floor, providing a sleek, glossy, and professional finish. It offers a wide range of design possibilities, including custom colours, aggregates, and patterns.


When considering regrinding and polishing, it’s important to assess the condition of your existing floor and consult with a professional contractor who specialises in concrete polishing. They can evaluate the feasibility of the project, recommend the appropriate steps, and provide an estimate of the costs involved, we can do this via the phone & also offer free site visits.
