Thinking about renovating your space with microcemento? It’s a fantastic choice—modern, seamless, and stylish. But here’s the truth: while microcement looks simple, applying it properly is anything but. It’s a technical process that requires experience, the right materials, and a lot of attention to detail.
In this guide, we’ll walk you through the most common mistakes people make when applying microcement, and how to avoid them—so your walls, floors, or bathrooms turn out as beautiful and durable as you imagined.
1. Skipping Surface Preparation
This is the #1 reason microcement fails. People often apply it over a surface that’s dusty, damp, cracked, or just not ready. When that happens, the microcement can:
- Crack
- Bubble
- Peel away from the surface
How to avoid it:
Make sure the surface is completely clean, dry, stable, and level before applying anything. Any imperfections underneath will show through—or worse, ruin the finish over time.
2. Rushing the Drying Process
Microcement is applied in layers. Each one needs proper drying time before you move to the next. But many people rush the job, and that’s when issues start:
- Cracks
- Uneven color
- Weak resistance to wear
How to avoid it:
Follow the recommended drying times—no shortcuts. Drying too fast is a recipe for disappointment.
3. Using Cheap or Generic Products
Not all microcement is created equal. Low-cost options might save money at first, but often lead to:
- Poor adhesion
- Fading
- Surface damage with minimal use
How to avoid it:
Choose high-quality materials from reputable suppliers. A well-formulated microcement system will look better and last much longer.
4. Poor Sealing (or No Sealing at All)
The final sealing layer protects your microcement from stains, moisture, and scratches. But many people either apply too little or skip it altogether.
The result?
- Water stains
- Permanent marks
- Quick wear and tear
How to avoid it:
Apply the recommended number of coats of sealant, and make sure it’s compatible with your microcement system. Don’t treat this step like an afterthought—it’s essential.
5. Trying to DIY Without Experience
Let’s be honest: watching a few YouTube tutorials isn’t enough. Applying microcement isn’t like painting a wall—it’s a craft that takes training and hands-on experience.
What can go wrong?
- Uneven texture
- Trowel marks
- Cracks or poor adhesion
How to avoid it:
If you want great results, hire a professional. Someone with experience knows how to adapt the product to your space, conditions, and needs.
6. Using the Wrong System for the Room
Microcement in a bathroom is not the same as microcement on a kitchen floor or an outdoor patio. Each space has different requirements—like resistance to water, heat, or heavy traffic.
How to avoid it:
Make sure you’re using the right product system for each space. A good installer will help you choose the right combination of base coat, finish, and sealant.
Final Thoughts: Do It Right, or Do It Twice
Microcement is an amazing material—but only when applied correctly. When done right, it gives you a smooth, seamless finish that lasts for years. But if applied poorly, it can start to fail within weeks.
