5 Tips for Applying Microcement with Rockcote MicroStone

Rockcote, a leading Australian-owned brand known for its commitment to quality and service, is proud to introduce its MicroStone range. This innovative product line is designed to offer a natural microcement finish that exudes elegance and durability. In the following blog, we will share five expert tips for applying MicroStone to ensure a flawless and long-lasting finish!

Preparing the Surface

Proper surface preparation is the foundation of any successful microcement application. A well-prepared surface ensures strong adhesion and a smooth, flawless finish.

1. Clean the Surface:

Ensure the surface is dust-free, grease-free, and completely dry. Any moisture can hinder the adhesion of the microcement. Sand, grind, or acid etch any existing paint, coatings, or debris as required. This step is crucial to ensure the new layer adheres well.

For surfaces requiring regularisation, such as tiled walls or rough cement, apply a primer to improve bonding. Rockcote’s Keycote or High Adhesion Primer is ideal for this purpose. For more information on primers and additives, visit Rockcote’s Patching, Priming, and Additives.

2. Regularisation:

• Irregular surfaces need a regularisation procedure to create a smooth, level base for the microcement. This is essential for surfaces like walls with tiles or uneven cement.
• Apply a base coat to create a smooth, level surface. Use a trowel to spread the base coat evenly and allow it to dry completely. The base coat acts as a foundation, ensuring proper adhesion of the microcement. It is critical to follow the manufacturer’s instructions for mixing and application to achieve the best results.

Mixing and Application Techniques

Achieving the right consistency in your microcement mixture is crucial for a smooth and even application.

3. Mixing Microcement:

• Follow the manufacturer’s instructions precisely for mixing Part A (10L) and Part B (5L) of the MicroStone. Accurate proportions are essential for the mixture’s performance.
• Use a mechanical mixer to achieve a uniform, lump-free consistency. Mixing by hand can result in inconsistencies and lumps, which can affect the final finish.
• Ensure that the mixed product is used within the recommended timeframe to maintain its optimal properties.

4. Application Techniques:

• Apply the first coat of microcement with a trowel or spatula, ensuring an even spread. This coat will create a smooth base for the subsequent layers.
• Allow the first coat to dry completely before applying the second coat.
• The second coat should provide the desired texture and colour. Spread the microcement evenly, achieving the desired thickness, and smooth out the surface using a steel trowel or a finishing trowel.
• Additional coats may be required to enhance durability for floors. Each coat should be applied thinly and allowed to dry completely before the next application. Rockcote’s MicroStone can be used to achieve various textures, so experiment with different techniques to find the best finish for your project.

Finishing Touches

The final appearance of your microcement render can be significantly enhanced with careful finishing touches.

5. Sanding and Sealing:

• After the final coat of microcement has dried, gently sand the surface with fine-grit sandpaper to achieve a smooth, even finish. This step helps to remove any imperfections and create a uniform surface.
• Remove all sanding dust with a vacuum cleaner or damp cloth. It’s important to ensure the surface is completely clean before proceeding to the sealing stage.
• Apply a coat of sealer using a short-haired roller or brush. This step is crucial for protecting the microcement from stains, water damage, and wear. The sealer also helps to enhance the final appearance by bringing out the colour and texture of the microcement.
• Multiple coats of sealer may be applied to achieve the desired level of protection and enhance the final appearance. Follow the manufacturer’s instructions for drying times between coats.
• Finally, apply a finishing varnish to ensure complete water resistance and durability. Depending on the application area, choose between shiny, matte, or satin finishes. Shiny finishes are typically recommended for floors, while matte or satin finishes are preferred for walls. The finishing varnish provides an additional protection layer and enhances the microcement’s visual appeal.

Common Mistakes to Avoid

To ensure a flawless application, it’s important to be aware of common mistakes and how to avoid them.

1. Inadequate Surface Preparation:

• Skipping surface cleaning or regularisation can lead to poor adhesion and an uneven finish. Always ensure the surface is thoroughly prepared. Neglecting this step can result in the microcement peeling or cracking over time.

2. Incorrect Mixing:

• Inconsistent mixing can cause lumps and affect the application. Use a mechanical mixer and follow the manufacturer’s instructions precisely. Incorrect mixing can lead to variations in colour and texture, compromising the overall appearance.

3. Uneven Application:

• Applying microcement too thickly or unevenly can result in an inconsistent texture. Use a trowel to spread the material evenly in thin layers. Applying too much material at once can cause it to crack or not adhere properly.

4. Insufficient Drying Time:

• Rushing the drying process can compromise the finish. Allow each coat to dry completely before proceeding to the next step. Skipping this step can lead to a weak bond between layers, affecting the durability of the finish.

5. Neglecting Sealing and Finishing:

• Skipping the sealing process can leave the microcement vulnerable to damage. Always apply the recommended sealer and finishing varnish. Proper sealing protects the surface from stains, water damage, and wear, ensuring the longevity of the finish.
