Microcement has become an increasingly popular choice for modern interiors, offering a sleek, seamless finish that transforms floors, walls, and surfaces. However, achieving that flawless look isn’t as simple as mixing and applying—microcement is a highly technical material that requires expert handling to prevent common issues like cracking, uneven finishes, and premature deterioration. While DIY tutorials might make it seem straightforward, the reality is that improper application can lead to costly repairs and disappointing results. In this post, we’ll explore why professional application is essential for microcement and how expert installation ensures a durable, beautiful finish that stands the test of time.
Understanding Microcement’s Composition and Why It Cracks
Microcement is a polymer-modified cement-based coating applied in thin layers, typically ranging from 2-3mm in thickness. Its composition includes cement, water-based resins, additives, and fine aggregates, all carefully balanced to create a strong, flexible surface. However, this delicate balance is precisely why cracking occurs when application goes wrong. If the mixture ratio is off—too much water weakens the bond, while too little creates brittleness—cracks will inevitably appear. Temperature and humidity during application also play crucial roles; applying microcement in overly cold, hot, or humid conditions disrupts the curing process, leading to structural weaknesses. Additionally, the substrate must be perfectly prepared—any movement, moisture, or contamination in the underlying surface will transfer through the thin microcement layer, causing cracks to form as the material settles.
The Critical Importance of Surface Preparation, Mixing, and Environmental Control
Professional microcement application begins long before any material touches the surface. Proper surface preparation is paramount: professionals assess substrate stability, moisture levels, and structural integrity, addressing any issues before application. They know how to properly prime different surfaces—whether concrete, tile, wood, or plasterboard—ensuring optimal adhesion. Mixing microcement requires precision; professionals use calibrated tools and follow exact manufacturer specifications to achieve the perfect consistency every time. They also control the working environment, monitoring temperature and humidity levels, and adjusting application schedules accordingly. Each layer must be applied at the correct thickness, with adequate drying time between coats—rushing this process or applying layers too thick leads directly to cracking and delamination.
The Risks of DIY Microcement Application
When homeowners attempt DIY microcement installation, several common problems emerge. Cracking is the most frequent issue, often appearing within weeks or months of application due to improper mixing, inadequate surface preparation, or poor environmental conditions. Uneven finishes are another telltale sign of amateur application—inconsistent layer thickness creates unsightly variations in color and texture that are virtually impossible to correct without complete removal. Reduced durability is perhaps the most concerning risk; without proper sealing techniques and layer application, DIY microcement may chip, stain, or wear prematurely, requiring expensive professional remediation far sooner than properly installed surfaces. Many DIYers also underestimate the physical demands and technical skill required, resulting in rushed work, missed preparation steps, and ultimately, a surface that fails to deliver on microcement’s promise of seamless beauty.
The Expertise Professionals Bring to Microcement Installation
Professional microcement applicators bring years of training, specialized tools, and hands-on experience that simply cannot be replicated through online tutorials. They possess technical skills honed through hundreds of installations, understanding exactly how materials behave under different conditions and how to adjust techniques accordingly. Professionals use industrial-grade tools—specialized trowels, mixing equipment, and application instruments—that ensure uniform coverage and proper texture. Their experience allows them to anticipate and prevent problems before they occur, identifying potential issues with substrates, environmental conditions, or project timing that inexperienced applicators would miss. Perhaps most importantly, professionals stand behind their work with guarantees and warranties, providing peace of mind that DIY installation can never offer. They understand the nuanced artistry required to achieve microcement’s signature seamless appearance, blending layers imperceptibly and creating the smooth, sophisticated finish that makes this material so desirable.
Real-World Examples: Amateur Application vs. Professional Results
Consider the case of a homeowner who attempted to install microcement in their bathroom after watching online tutorials. Within three months, hairline cracks appeared throughout the floor, and several areas near the shower began to lift and discolor. The substrate hadn’t been properly sealed against moisture, the mixing ratios were inconsistent, and layers were applied too quickly without adequate drying time. The eventual repair cost twice as much as hiring a professional would have initially, requiring complete removal and reinstallation. In contrast, a similar bathroom professionally installed by PerfectlyPlastered has remained flawless for over five years, withstanding daily moisture exposure and heavy use without a single crack or blemish. Another common scenario involves kitchen floors where DIY applicators fail to account for underfloor heating systems—improper application over these surfaces leads to rapid cracking as materials expand and contract. Professional installers know how to work with these systems, using flexible primers and appropriate application techniques that accommodate thermal movement.
Another example involves a commercial space where the business owner attempted to save costs by applying microcement themselves on a high-traffic retail floor. Within six months, the surface showed significant wear patterns, uneven areas where layers were too thin, and multiple cracks radiating from stress points. The unprofessional appearance damaged the business’s image and ultimately required professional remediation. Compare this to professionally installed microcement in similar commercial environments—PerfectlyPlastered has completed numerous retail, hospitality, and office installations that maintain their pristine appearance years later, even under intense daily use. The difference lies not just in technical application, but in understanding traffic patterns, stress points, and selecting appropriate product specifications for each unique environment.
