How to apply microcement in the staircase? Step by step guide

Using microcement on stairs is an excellent way to achieve a stylish and modern look with a durable and seamless surface. Microcement is a thin cement-based coating that can be applied over various surfaces such as wood, concrete, and tiles. In this article, we will explore the benefits of using microcement on stairs and provide a step-by-step guide on how to apply microcement to stairs. Benefits of Microcement Stairs Stairs are one of the most trafficked areas in homes, used several times a day, which leads to wear and tear. By using microcement, you not only add a modern look to the stairs but also gain high durability and resistance to wear and traffic. Below, we explain the main benefits of using microcement stairs:

1. Microcement Stairs Promote Continuity Microcement-covered stairs are gaining more attention every day because, unlike wooden or parquet stairs, they do not require expansion joints. This adds value as microcement stairs promote continuity of the stairs and, more importantly, the room they are in. All elements (stairs, floor, walls, ceiling) are seen as an integrated whole, creating an appearance of absolute continuity that can be enhanced by matching the color of the stairs with the floor.

2. Avoid Construction Work with Microcement Stairs Microcement is a decorative coating with excellent adhesion that can be applied directly over existing materials such as marble or concrete. This competitive advantage allows you to renovate stairs with microcement without the need for construction, waste generation, and with significant time and cost savings, in just a few hours.

3. Easy Cleaning of Microcement Stairs Small stairs usually do not pose a problem for cleaning. However, cleaning long stairs that connect floors can be complicated. Cleaning microcement stairs is very easy as they form a continuous, seamless surface that can be easily cleaned with a soft cloth or mop and a neutral pH cleaner.

4. Microcement Stairs Are Highly Durable If there's a distinctive element in microcement stairs, it's their durability. Thanks to their excellent resistance, especially to traffic, impact, and wear, they remain in excellent condition for years.

5. Microcement on Stairs Does Not Affect Structural Load The thin thickness of microcement (between 2 and 3 millimeters) ensures that coating stairs with microcement does not affect the structural load at all.

6. Microcement Stairs for Indoor and Outdoor Use Microcement stairs are a versatile architectural element that is mainly used in interior design due to the sense of stability, spaciousness, and cleanliness they provide. However, microcement stairs are also very popular for exterior use due to their elegance, grandeur, and presence.

7. Non-Slip Finish for Microcement Stairs The result of applying microcement stairs with a suitable finish is a safe, non-slip surface. How to Apply Microcement on Stairs Step 1: Preparation

• Surface Cleaning Thoroughly clean the stairs to remove any dust, dirt, grease, or old paint. A clean surface provides better adhesion for the microcement.
• Surface Repair Check the stairs for cracks, holes, or uneven areas. Use a suitable filler or repair mortar to fix these defects. Sand the surface to ensure it is smooth and even.
• Priming Apply a high-quality primer suitable for the type of surface you are working on. The primer increases adhesion between the existing surface and the microcement. Allow the primer to dry completely according to the manufacturer’s instructions. Step 2: Applying the Base Layer
• Mixing Microcement Prepare the microcement mix according to the manufacturer’s instructions. This usually involves mixing dry microcement powder with polymer or water to achieve a workable consistency.
• Applying the First Base Layer Use a trowel to apply the first base layer of microcement. Spread it evenly over the surface of the stairs, ensuring a uniform thickness. The base layer acts as a foundation for subsequent layers. Allow the first layer to dry completely, which typically takes 24 hours.
• Sanding After the base layer has dried, sand it lightly to remove any imperfections or rough spots. This step is crucial for achieving a smooth surface in the final layer. Clean the surface to remove any dust from sanding. Step 3: Applying Additional Layers
• Second Base Layer Apply the second base layer of microcement in the same manner as the first layer. This layer helps build the necessary thickness and ensures an even surface. Allow it to dry completely and sand it again to achieve a smooth finish.
• Preparing the Final Layer Prepare the final layer of microcement mix, which may have a slightly different composition or texture to create a smoother surface. Step 4: Applying the Final Layer
• Applying the Final Layer Use a trowel to apply the final layer of microcement, ensuring it is smooth and even. This layer should be thin but uniform and should cover any remaining imperfections from the previous layers. Take your time to make the final surface as smooth as possible.
• Adding Texture If desired, you can add textures or patterns to the final layer using various tools or techniques. This step allows for customization and creativity, giving your stairs a unique look. Step 5: Finalizing
• Sanding and Polishing Once the final layer is completely dry, sand the surface lightly to remove any minor imperfections and achieve a smooth finish. For a glossy appearance, you can use finer grit sandpaper or a polishing machine.
• Sealing To protect the microcement and enhance its durability, apply a sealer or varnish. Choose a sealer suitable for microcement that provides the desired level of gloss. Apply the sealer in multiple thin coats, allowing each coat to dry completely before applying the next one.

Step 6: Curing

• Allowing Microcement to Cure Proper curing is crucial for the full strength and durability of microcement. Allow the stairs to cure for at least seven days before subjecting them to heavy traffic. Avoid cleaning with water or harsh chemicals during this period. Maintenance Tips
• Regular Cleaning Keep the microcement stairs clean by regularly wiping them with a soft cloth or mop and a neutral pH cleaner. Avoid abrasive cleaners or tools that might damage the surface.
• Periodic Sealing Depending on the amount of traffic and wear, you may need to reapply the sealer periodically to maintain the protective layer and appearance of the microcement. Conclusion Applying microcement on stairs is a meticulous process that requires attention to detail and patience. However, the result is a stunning, durable, and modern surface that can transform the look of any staircase. By following these step-by-step instructions, you can achieve professional-quality microcement stairs that are both functional and beautiful.
