Microcement vs Polished Concrete

In this article, we will explore the differences between microcement and polished concrete, comparing their qualities, advantages, disadvantages, finishes, applications, pricing, and more.

What is Polished Concrete?

Polished concrete, also known as screed concrete, is a decorative finish rather than a pure cladding.

It is used in indoor and outdoor areas like parking, shopping centres, extensions, and living rooms.

Polished concrete is a finish achieved by sprinkling a cementitious mortar with aggregates and then polishing the floor to a shine using a rotary polisher.

Microcement vs Polished Concrete: Top 11 advantages of microcement over polished concrete

When it comes to comparing microcement and polished concrete, one common question we often receive is about the benefits of microcement over polished concrete. Based on our extensive experience in the field, we have identified several key advantages of microcement:

1. More Control of Colour & Finish

Microcement offers greater control over colour, tone, texture, and overall aesthetics compared to a polished concrete finish.

The method of application and precise measurements of products and pigments allow for a wide range of customization options.

2. Low Applied Thickness

Microcement can be applied at a depth of only 2-3mm (excluding any necessary preparation). This is significantly thinner than the minimum thickness of 100mm typically required for a polished concrete floor. The reduced thickness makes microcement a suitable choice when height limitations are a concern.

3. Multiple Uses & Applications

Microcements are highly versatile and can be applied on various surfaces such as walls, floors, ceilings, and stable substrates in both residential and commercial environments. This flexibility expands the design possibilities and allows for cohesive aesthetics throughout a space.

4. Less Heavy / Noisy Machinery

Unlike polished concrete, microcement application does not typically require heavy and noisy grinding or diamond polishing tools. This aspect makes microcement installation feasible in areas where traditional polished concrete would have been impractical or disruptive.

5. Fast Drying / Installation Time

The application time for a microcement finished floor is significantly reduced compared to that of a polished concrete surface. Typically, a standard microcement installation takes around 4-5 days (which may vary depending on the size and complexity of the project). The faster drying time allows for quicker project completion.

6. Installation Timing Flexibility

Due to the reduced installation time requirements, microcement can be applied towards the end of a project. This timing flexibility reduces the risk of damage or compromise resulting from other trades or third-party activities. For example, microcement installation can take place once a kitchen has been fully installed.

7. Retro Fitting / Installation Possibilities

Microcements offer the advantage of retro-fitting in many cases. As long as the existing substrates are stable, microcement can be applied over various floor finishes with minimal height build-ups or the need for extensive excavation.

8. Less Cracking

Microcements are inherently less prone to cracking compared to polished concrete floors.

To further minimize the possibility of cracking, proper installation practices should be followed. This includes correctly installing and curing new substrates, ensuring proper drying and commissioning of underfloor heating systems before microcement application.

9. Compatibility with Underfloor Heating

Microcement is compatible with underfloor heating systems due to its high thermal conductivity, while polished concrete is not.

10. Debris Generation

Microcement can be applied directly to existing surfaces without producing debris, while polished concrete requires construction work that generates debris.

11. Expansion Joints

Polished concrete requires expansion joints every 4 to 5 meters to accommodate potential movement, whereas microcement is a continuous covering and doesn’t require expansion joints.

In conclusion, microcement presents several distinct advantages over polished concrete, including greater control over aesthetics, thinner application thickness, versatility in usage, reduced reliance on heavy machinery, faster installation time, flexible timing, retro-fitting possibilities, and improved resistance to cracking. These factors make microcement a compelling option for those seeking a customizable and practical flooring solution.

How to Install Polished Concrete Floors?

The installation process for a polished concrete floor is similar to other types of concrete flooring. It involves preparing the ground, shuttering, pouring concrete, checking slab thickness, curing concrete, and polishing the floor.

Here is a general overview of the process:

Surface Preparation: The first step is to prepare the concrete surface. This includes cleaning the floor thoroughly to remove any dirt, debris, or coatings. Any cracks or imperfections should be repaired, and the surface should be leveled if needed.
Grinding: Once the surface is prepared, the grinding process begins. Specialized grinding machines equipped with diamond-impregnated discs are used to remove the top layer of the concrete and expose the underlying aggregate. The grinding is typically done in multiple passes with progressively finer grits to achieve the desired level of smoothness.
Polishing: After grinding, the concrete is polished to enhance its shine. The polishing process involves using resin-bonded diamond pads, starting with coarser grits and gradually moving to finer grits. This helps achieve a smooth and reflective surface. A densifier may also be applied during the polishing process to improve durability and stain resistance.
Sealing: Once the desired level of polish is achieved, the floor is thoroughly cleaned to remove any dust or residue. A sealer is then applied to protect the polished concrete and enhance its appearance. The sealer can provide additional stain resistance and make maintenance easier.
Maintenance: To keep the polished concrete floor in optimal condition, regular maintenance is necessary. This typically involves routine cleaning with a neutral pH cleaner and periodic reapplication of a maintenance coating or wax to maintain the shine and protect the surface.

It is important to note that creating a polished concrete floor is a skilled process that requires expertise and specialized equipment. Hiring a professional contractor experienced in polished concrete is recommended to ensure the best results and a long-lasting, beautiful floor.
