How to Apply Microcement 

Are you considering using microcement for your next project? If that’s the case, it’s important to understand the correct techniques to achieve the results you’re aiming for. Microcement application is a nuanced process that requires precision and attention to detail.

This versatile material can transform any space into a sleek, modern environment. Have a look at our comprehensive guide for a detailed step by step on how to apply microcement successfully.

6 Steps of Microcement Application

Our application of microcement step by step guide covers everything from preparation to the final touches. Whether you’re a seasoned professional or a DIY enthusiast, these steps will ensure a flawless finish.

1. Surface Preparation

First, make sure the surface is free from dust and grease, completely dry (without capillary or plaster/cement moisture), and as level or smooth as can be. Microcement can be applied on two types of surfaces: those needing a regularization procedure (like walls and floors with tiles or cement plaster) and completely smooth surfaces (such as smooth caulked walls or entirely smooth walls).

For microcement floors, regularisation is needed no matter the finish. If both floors and walls need regularisation, additional preparation steps are necessary. However, for smooth walls, the process is speedier and less expensive. Once the surface is checked, protective tape is used to safeguard areas not meant for microcement application.

2. Surface Regularisation – Base Coat Application

After making sure the surface is prepped and ready, the next step is applying the primer. This first layer is vital to ensure the microcement sticks properly to the surface. Start by applying a primer—this will significantly improve the bond between the microcement and the substrate.

After the primer, make sure to mix the base coat material accurately, following the manufacturer’s guidelines. Using a trowel or spatula, spread this mixture evenly across the surface, ensuring consistent coverage. It’s important to let this base coat dry thoroughly before moving on to the next steps in the application process. This not only ensures adhesion but also creates a solid base for the upcoming layers.

3. Second Coat Application

Once the base coat has dried thoroughly, it’s time to move on to the second coat of microcement, a pivotal step in achieving the final look and feel of the surface. This layer is where the desired colour and texture really start to show.

The process involves carefully mixing microcement material, pigment, and water in specific proportions as advised by the manufacturer. With a steady hand, this mixture is applied over the prepared surface using either a trowel or a spatula, paying close attention to detail to ensure an even spread of the intended thickness.

After spreading, a steel trowel or a finishing microcement trowel is used to refine the surface, smoothing it out for a seamless finish. It’s crucial to allow this second coat enough time to dry, following the manufacturer’s recommended timing, before moving on to the next stages of the application.

4. Sanding

Once the critical layer of the second coat has completely dried, the next vital step in the microcement application process is sanding. This phase is crucial for achieving a flawlessly smooth and even surface, essential for the final appearance and texture.

It is recommended to use either a sanding block or a sanding machine, along with fine-grit sandpaper, to gently sand the surface in circular motions. This careful attention helps to even out any irregularities and smooth the entire area.

Once the sanding of the surface is done clean the dust with a vacuum cleaner or damp cloths and the protective tape must be removed. A final inspection of the surface is necessary to verify its smoothness and readiness for the concluding application step, guaranteeing the perfect foundation for the finishing touches.

5. Sealing

The last crucial step in the microcement application process involves sealing the surface, a vital process for ensuring the long-term durability and aesthetic quality of the microcement. This step serves multiple purposes; it not only provides strong protection against stains and water damage but also significantly enhances the overall durability of the microcement. Applying a sealer helps in getting rid of absorption, giving the microcement those desirable waterproof qualities.

Furthermore, sealing has the added benefit of enhancing the final colour of the microcement, enriching its appearance. For easier application, it is recommended to use a short-haired roller or a brush. The sealing process progresses as follows: Begin by evenly applying a coat of sealer across the surface, adhering strictly to the guidelines provided by the manufacturer.

Allow this initial coat to dry thoroughly. Depending on the desired level of protection, additional coats may be necessary; make sure each coat is allowed to dry completely before applying the next.After the final coat, it is essential to allow the sealed surface a sufficient curing period, as recommended, before it is subjected to heavy use or cleaning. This ensures the optimum protection and longevity of the microcement surface.

6. Finishing Varnish

The application of the final varnish is the last step in the microcement process, acting as the ultimate shield. Its crucial role cannot be overstated, guaranteeing the microcement is fully waterproof and resistant to standard cleaning agents like bleach, ammonia, and anti-limescale products. Consumers can choose from three varnish finishes – glossy, matt, and satin – for a personalised look depending on the surface.

Glossy varnishes are commonly recommended for floors due to their toughness and visual appeal, while matt or satin finishes are preferred for walls, offering a more subtle shine. For optimal protection, it is advisable to apply two to three coats of the chosen varnish using a short-haired roller, ensuring each coat is applied evenly and allowed to dry completely before proceeding.

How to Apply Microcement in Different Areas?

Microcement’s flexibility makes it a perfect option for a wide range of uses, from flooring to walls in homes and businesses alike.

Application of Microcement on Walls

If you’re revamping your walls, here’s how to apply microcement step by step:

Will a microcement crack?

The microcement itself won’t crack, but if the base layer’s strength to resist cracks is too high, surpassing the microcement’s flexibility, it’ll end up pulling. So, laying strong foundations is key to achieve the desired outcome.

This stresses the importance of thorough groundwork preparation and fortifying the base before applying the microcement. Ensuring the underlying surface is sturdy, with reduced stress points and sufficient flexibility, is crucial. This not only prevents unsightly cracks but also boosts the overall longevity and durability of the microcement finish.

What is the best base for microcement?

The perfect foundation for microcement needs to be solid, stable, and free from any movement or flex. Surfaces like concrete, cement screeds, or mortar are usually the best choices as they offer a robust base that can bear the weight of the microcement without shifting.

Moreover, these materials have an absorbency level that complements the optimal adhesion of the microcement. Before applying, it’s crucial to ensure the base is not just structurally sound but also correctly levelled, clean, and dry. Thoroughly preparing the base can significantly impact the durability and visual appeal of the microcement finish, preventing potential issues like cracking or peeling.

Is Microcement cheaper than tiling?

When you look at microcement compared to traditional tiling, the cost can vary based on factors like the area size, project complexity, and the type and quality of materials used. Generally, microcement can be a more budget-friendly choice long-term due to its durability, minimal maintenance needs, and no grouting required, which can cut labour costs.

Moreover, microcement gives a seamless and flexible finish, letting you apply it over existing surfaces without removal, potentially saving on preparation time and costs. However, the initial costs might be higher because of the need for specialist installation skills.

How long does microcement last?

When microcement is properly installed and well-maintained, it can stand the test of time, offering a durable and classic aesthetic appeal. The longevity of microcement greatly depends on the quality of the installation, from preparing the base layer to applying the technique. Regular upkeep and the use of appropriate sealants are also vital in maintaining the surface’s integrity over the years.
