What Is Microcement and Why It Works on Drywall
Understanding Microcement as a Decorative Continuous Coating
Microcement is a thin, cement-based decorative coating applied in multiple layers, typically totalling just 2–3 mm. Unlike tiles or plaster, it creates a continuous, joint-free surface that feels modern, refined, and architectural.
Because microcement is lightweight and highly adhesive when used with the correct primers and reinforcement systems, it adapts beautifully to a wide range of substrates—including drywall
Why Drywall Is a Suitable Substrate for Microcement
- Drywall (also known as plasterboard) is stable, flat, and widely used in interior construction. When correctly installed and prepared, it provides an excellent base for microcement. The key lies in reinforcement and elasticity, allowing the coating to move subtly with the surface beneath.
Can You Apply Microcement Directly Over Drywall?
Yes—but never without preparation.
Key Conditions Drywall Must Meet Before Application
Structural Stability and Fixings
Drywall panels must be securely fixed to a rigid framework. Any movement—however slight—can cause cracking in the finished microcement surface.
Surface Flatness and Joint Treatment
All joints must be properly taped and filled. Uneven seams will telegraph through the microcement, especially under natural or directional lighting.
Benefits of Applying Microcement Over Drywall
Lightweight Solution for Walls and Ceilings
Unlike traditional cement renders, microcement adds minimal weight. This makes it ideal for drywall partitions, ceilings, and decorative features where structural load is a concern.
Seamless, Modern Aesthetic Without Demolition
Why tear down walls when you can transform them? Microcement over drywall allows for a complete visual overhaul without demolition—saving time, money, and mess.
Is Microcement Over Drywall Durable Long-Term?
Crack Resistance and Flexibility
When installed as part of a complete system, microcement over drywall is remarkably durable. The elasticity of Topcret products allows them to absorb subtle movement without cracking.
Maintenance and Longevity Expectations
Maintenance is simple—regular cleaning with neutral products is enough. With proper sealing, microcement can last decades, even on drywall substrates.
Microcement Over Drywall in Wet Areas
Bathrooms, Kitchens, and Moisture Control
Yes, microcement can be used over drywall in bathrooms and kitchens—but only with moisture-resistant boards and waterproof sealing systems. When done correctly, the result is a seamless, waterproof surface ideal for modern wet areas.
Design Ideas for Microcement on Drywall Surfaces
Feature Walls, Fireplaces, and Ceilings
Microcement over drywall shines in:
TV feature walls
Fireplace surrounds
Statement ceilings
Commercial partitions
Its continuous texture and subtle tonal variation add depth without visual clutter.
Professional vs DIY Application: What Should You Choose?
While DIY kits exist, drywall applications demand experience. Incorrect preparation can lead to cracking or delamination. For guaranteed results, professional installation using Topcret systems is strongly recommended.
Conclusion: Is Microcement Over Drywall the Right Choice?
Microcement over drywall isn’t just possible—it’s a powerful design solution. When applied correctly with reinforcement, primers, and professional sealing, it delivers durability, elegance, and versatility unmatched by traditional finishes.
If you’re looking for a seamless, contemporary surface without structural changes, Topcret microcement over drywall is an outstanding choice.
