It’s worth noting that while micro concrete shares similarities with other cementitious coatings like micro cement and polished concrete, there may be slight differences in terms of composition and application techniques depending on the specific product and manufacturer.

Micro concrete mix ratio:

The mix ratio for micro concrete can vary depending on the specific application and desired strength. However, a commonly used mix ratio for micro concrete is:

• Cement: Sand: Water = 1:2:0.5

This means that for every part of cement, you would use two parts of sand and 0.5 parts of water.

It’s important to note that this ratio is just a general guideline and can be adjusted based on factors such as the desired strength, aggregate size, and other additives used in the mix. It’s always recommended to refer to the manufacturer’s instructions or consult with a concrete expert for specific projects to ensure the best results.

Micro concrete texture:

Micro concrete texture refers to the surface finish or pattern created on a micro concrete surface. It’s also known as micro-topping or skim coat is a thin layer of concrete typically applied to existing surfaces such as floors, walls, or countertops to achieve a decorative and durable finish.

The texture of micro concrete can vary depending on the desired aesthetic effect. Here are a few common micro concrete textures:

1. Smooth Texture: This texture is achieved by applying the micro concrete mixture evenly and then toweling it to create a smooth and polished surface. It gives a smooth & contemporary look.
2. Trowel Texture: By using a trowel, the micro concrete can be manipulated to create various patterns and textures. The trowel marks add subtle variations and a slightly rougher finish.
3. Stamped Texture: This texture is achieved by pressing stamps or templates into the micro concrete surface while it is still wet. Stamps can mimic the appearance of materials like stone, brick, or wood, creating a textured and realistic finish.
4. Stenciled Texture: Stencils can be used to create intricate patterns on the micro concrete surface. The stencil is laid on the wet micro concrete, and a trowel or a roller is used to apply a contrasting color or texture. When the stencil textures are removed, the pattern will remain.
5. Exposed Aggregate Texture: This texture is achieved by incorporating decorative aggregates, such as small stones or glass chips, into the micro concrete mix. Once the surface is troweled and cured, the aggregates are partially exposed, creating a textured and decorative finish.
6. Burnished Texture: This texture is created by using a burnishing tool, such as a power trowel or a burnishing pad, to polish the micro concrete surface. It results in a smooth and glossy finish with a subtle sheen.

These are just a few examples of textures that can be achieved with micro concrete. The choice of texture depends on the desired aesthetic, functionality, and techniques employed during the application process.

Micro concrete specifications:

1. Composition: It is typically a blend of Portland cement, fine aggregates (such as silica sand or quartz), polymers, and additives. The exact composition may vary depending on the manufacturer and specific product.
2. Thickness: Micro concrete is applied in thin layers, usually ranging from 1 to 3 millimeters. However, the thickness can vary based on the desired effect and application requirements.
3. Surface preparation: The substrate or surface where micro concrete will be applied should be properly prepared. This usually involves cleaning the surface, repairing any cracks or imperfections, and ensuring it is stable and free from dust, grease, or other contaminants.
4. Application method: It can be applied by troweling, spraying, or rolling, depending on the manufacturer’s recommendations and the desired finish. It’s necessary to follow the manufacturer’s instructions for proper application techniques.
5. Curing: After application, micro concrete needs sufficient time to cure and harden. The curing time can vary but is typically around 24 to 48 hours. During this period, it’s crucial to protect the surface from moisture and physical damage.
6. Finishing: It can be finished in various ways, such as polishing, burnishing, or applying a protective sealer. The desired aesthetic and functional requirements will determine the appropriate finishing techniques.
7. Colors and patterns: Micro concrete is available in a wide range of colors, allowing for versatile design possibilities. It can also be used to create patterns, textures, or even mimic the appearance of other materials like stone or marble.

It’s important to note that these specifications can vary depending on the specific product and manufacturer. Therefore, it’s always recommended to refer to the manufacturer’s technical data sheet and follow their guidelines for the particular micro concrete product you are using.
