Step 1: Assess and Prepare the Floor Surface
Successful microcement floor installation begins with meticulous surface preparation. Getting this initial stage right determines the longevity and aesthetic quality of your final floor finish. Understanding how to properly evaluate and ready your substrate is absolutely critical.
Start by thoroughly examining your existing floor surface. You will need to check for critical factors such as moisture content, structural integrity, and overall levelness. Substrate preparation principles vary depending on your base material whether you are working with wood, concrete, or existing tiling. Look for signs of damage including cracks, uneven areas, or structural weaknesses that could compromise your microcement application.
Clean the surface completely using professional degreasing agents and ensure all dust, debris, and loose materials are removed. Sanding might be necessary to create a smooth, receptive surface that allows proper microcement adhesion. For wooden surfaces, pay special attention to checking moisture levels and potential movement that could cause future cracking. Concrete substrates require different preparation techniques including potential levelling compound application to create a perfectly flat foundation.
Expert Tip: Always perform a moisture test and allow at least 48 hours for substrate acclimation before beginning your microcement installation to prevent future complications.
Here’s a comparison of substrate preparation requirements for microcement flooring:
| Substrate Type | Key Preparation Step | Main Risk if Skipped | Recommended Solution |
|---|---|---|---|
| Concrete | Levelling compound | Uneven finish | Self-levelling screed |
| Wood | Moisture testing | Cracking | Install vapour barrier |
| Tiling | Surface sanding | Poor adhesion | Use primer and sand thoroughly |
Step 2: Apply the Primer for Strong Adhesion
Applying the right primer is a critical step in ensuring your microcement floor achieves maximum durability and aesthetic appeal. The primer acts as a crucial bridge between your prepared substrate and the final microcement layer, creating a robust foundation for your flooring installation.
Begin by selecting a high-quality primer specifically designed for microcement applications. Carefully read the manufacturer’s instructions and choose a primer compatible with your specific substrate type whether you are working on concrete, wood, or existing tiling. Using a roller or specialist application brush, apply the primer evenly across the entire surface ensuring complete and consistent coverage. Pay close attention to maintaining a uniform thickness and avoiding pooling or uneven areas that could compromise the final finish.
Allow the primer to dry completely according to the manufacturer’s recommended timings. This typically ranges between 2 to 4 hours depending on environmental conditions such as temperature and humidity. The primer should feel slightly tacky but not wet when touched this indicates it is ready for the next stage of microcement application. Ensure proper ventilation during the drying process and avoid walking on the primed surface to prevent any potential contamination or disruption.
Expert Tip: Use a lint free roller and apply the primer in thin crossed layers to guarantee optimal adhesion and prevent potential bubbling or uneven surfaces.
Step 3: Mix and Spread the Microcement Layers
Applying microcement requires precision and technique to achieve a seamless, professional finish across your floor. The mixing and spreading process is where your craftsmanship truly comes to life, transforming the prepared surface into a stunning architectural feature.
Begin by carefully measuring the microcement powder and liquid components according to the manufacturer’s precise instructions. Microcement flooring installation demands exact proportions to ensure optimal consistency and performance. Use a clean mixing bucket and a mechanical mixer to combine the ingredients thoroughly, avoiding air bubbles and achieving a smooth paste with a cream like texture. Mix only the amount you can apply within 30 minutes to prevent material wastage and maintain optimal working properties.
Apply the microcement using a stainless steel trowel, working in thin successive layers of approximately 1 to 2 millimetres. Spread the material systematically across the primed surface using smooth consistent movements. Ensure each layer is completely even and free from imperfections, overlapping slightly with previous applications to create a uniform finish. Allow each layer to dry partially before applying the next coat this technique helps prevent cracking and ensures a robust final surface.
Expert Tip: Always mix microcement in small batches and maintain consistent trowel pressure to achieve a perfectly smooth and uniform layer without visible joins or inconsistencies.
Step 4: Sand and Seal for Lasting Protection
The final stage of your microcement floor installation involves carefully sanding and sealing the surface to create a durable, professional finish that will protect your investment for years to come. This critical step transforms your raw microcement application into a resilient and aesthetically pleasing floor surface.
Begin the sanding process using fine grit sandpaper or a professional orbital sander with progressively finer grades. Start with a medium grit (120 to 180) and gradually move to a fine grit (240 to 320) to achieve a smooth, even surface. Microcement flooring installation requires gentle yet thorough sanding to eliminate any minor imperfections while maintaining the layer’s integrity. Work systematically across the entire surface ensuring uniform treatment and avoiding over sanding any particular area.
After sanding, carefully remove all dust using a clean microfibre cloth and prepare to apply the protective sealer. Choose a high quality microcement specific sealer that complements the colour and finish of your floor. Apply the sealer using a short nap roller in thin, even coats ensuring complete coverage without pooling. Allow each coat to dry completely before applying the next typically waiting around 2 to 3 hours between applications. Most microcement floors require two to three protective sealer coats for optimal durability and resistance to wear.
Expert Tip: Use a lint free roller and apply sealant in crossed layers with light even pressure to guarantee complete coverage and prevent potential streaking or uneven protection.
Step 5: Inspect and Finish the Microcement Floor
The final stage of your microcement floor installation involves a comprehensive inspection and meticulous finishing process that ensures your new floor meets the highest standards of quality and aesthetic appeal. This crucial step transforms your hard work into a professional result that will stand the test of time.
Professional microcement floor inspection techniques require systematic examination of the entire surface for potential imperfections. Begin by carefully checking the floor under different lighting conditions natural daylight and artificial light to reveal any subtle irregularities. Look closely for colour consistency, surface smoothness, and any areas that might require additional attention. Pay special focus to edges, corners, and transition zones where application techniques can sometimes reveal minor inconsistencies.
Allow the floor to cure completely before permitting full foot traffic typically waiting at least 48 hours after the final sealer application. During this curing period, restrict access to the area and maintain a consistent room temperature between 15 and 25 degrees Celsius. Once fully cured, conduct a final walkthrough to ensure the surface meets your expectations. Gently run your hand across the floor to check for smoothness and use a soft cloth to test the sealer’s finish ensuring a uniform and protective coating.
Expert Tip: Keep several clean microfibre cloths and a small touch up kit nearby during the final inspection to immediately address any minor imperfections you might discover.
Review the main quality checks for finished microcement floors:
| Inspection Point | What to Look For | Typical Correction |
|---|---|---|
| Surface Smoothness | No ridges or bumps | Gentle sanding |
| Colour Consistency | Uniform appearance | Spot retouch of colour |
| Edge Neatness | Clean transitions | Careful trimming |
| Sealer Finish | Even, streak-free coat | Reapply thin layer |
