MyCROCEMENT™ Troubleshooting Guide | Fix Peeling, Cracking & Surface Issues
Microcement problems like peeling, cracking, visible mesh, or uneven texture are almost always caused by surface preparation, layer thickness, or curing time. This troubleshooting guide explains the most common microcement application issues, what causes them, and how to fix them correctly.
If you’re using MyCROCEMENT™, most problems are preventable by following the proper installation process.
Why Most Microcement Problems Happen
Most microcement failures are not material defects — they are application errors.
Traditional microcement systems require:
- Precise on-site mixing ratios
- Controlled water addition
- Rushed timing of application between layers
- Extended time to apply layers of product
Inconsistent mixing, or rushed or slow steps increase the risk of peeling, cracking, and surface defects or other defects due to early setting of the components.
MyCROCEMENT™ is premixed and ready-to-use to reduce these variables, it’s also very forgiving with ample times to apply — but correct preparation and application still matter.

Common Issues & How to Fix Them
1. Microcement Peeling or Poor Adhesion
Symptoms
- Peeling
- Flaking
- Lifting from substrate
- Hollow spots
Possible Causes
- Surface was dusty, dirty, or unstable
- Primer was skipped or not fully dry
- Base coat applied too thick
How to Fix
- Remove the affected area completely
- Re-clean and ensure substrate stability
- Reapply primer properly
- Apply base coats in thin, even layers
👉 Most adhesion issues are prep-related.
2. Visible Mesh Showing Through Microcement
Symptoms
- Reinforcement mesh visible through surface
- Slight grid pattern showing
Possible Causes
- Mesh not fully embedded in base coat
- Base coats applied too thin
How to Fix
- Apply an additional thin base coat
- Ensure mesh is fully encapsulated
- Lightly sand before applying finish coat
3. Trowel Marks or Uneven Texture
Symptoms
- Ridges
- Drag lines
- Heavy texture
- Inconsistent finish
Possible Causes
- Overworking material while setting
- Inconsistent trowel pressure
- Finish coat applied too thick
How to Fix
- Lightly sand high spots
- Apply final finish coat with controlled pressure
- Work in smaller sections
👉 Remember: subtle variation is normal. Heavy ridges are not.
4. Microcement Staining or Discoloration
Symptoms
- Water rings
- Dark spots
- Uneven color tone
Possible Causes
- Sealer applied unevenly
- Surface not dust-free before sealing
- Insufficient number of sealer coats
How to Fix
- Clean surface thoroughly
- Lightly abrade if necessary
- Reapply sealer evenly
- Follow correct cure times
5. Cracking or Hairline Fractures
Symptoms
- Fine cracks in surface
- Spider-web style lines
Possible Causes
- Substrate movement
- Base coats applied too thick
- Rushed drying time
- No reinforcement mesh where required
How to Fix
- Verify substrate stability
- Sand down affected area
- Reapply base coat properly
- Follow recommended layer thickness and drying times
How to Prevent Problems Before They Start
Most issues come from skipping prep or rushing steps.
Follow these principles:
- Ensure the substrate is stable and solid
- Always prime properly
- Apply thin, even layers
- Respect drying times
- Use mesh when required
- Do not rush the sealing process

FAQs
1. Why is my microcement peeling?
Microcement peeling is usually caused by poor surface preparation, lack of primer, or applying base coats too thick. The substrate must be clean, stable, and properly primed before application.
2. Why can I see mesh through my microcement?
Visible mesh typically means the reinforcement was not fully embedded or the base coats were applied too thin. Apply an additional thin base coat to fully encapsulate the mesh.
3. Why is my microcement cracking?
Hairline cracks often result from substrate movement, coats applied too thick, or insufficient curing time between layers. Always apply thin coats and respect drying times.
4. How do I fix trowel marks in microcement?
Lightly sand high spots and apply a controlled, even finish coat using consistent trowel pressure. Avoid overworking the material as it begins to set.
5. Why is my microcement staining?
Staining usually occurs when sealer is applied unevenly or the surface was not dust-free before sealing. Clean and reapply sealer evenly while respecting cure times.
