MyCROCEMENT™ Troubleshooting Guide
Introduction
This guide helps identify and fix common issues during or after microcement application. Follow these recommendations to maintain professional results and prolong the life of your surface.
1. Poor Adhesion
Symptoms: Microcement peeling, flaking, or coming off the substrate.
Possible Causes:
- Surface was not stable or clean
- Primer not applied or insufficient drying
- Base coat applied too thick or uneven
Fix:
- Remove affected area
- Re-clean and prep surface
- Apply primer and base coats as per guide
2. Visible Mesh
Symptoms: Mesh fibers showing through base or finish coats.
Possible Causes:
- Mesh not fully embedded in base coat
- Base coats too thin
Fix:
- Apply a thin additional base coat to fully cover the mesh
- Sand lightly between coats if needed
3. Trowel Marks or Uneven Texture
Symptoms: Lines, ridges, or uneven texture visible in finish coats.
Possible Causes:
- Overworking material as it sets
- Inconsistent trowel pressure
- Finish coat applied too thick
Fix:
- Lightly sand high spots
- Apply second finish coat with controlled, consistent pressure
4. Staining or Discoloration
Symptoms: Surface shows spots, water rings, or uneven color.
Possible Causes:
- Sealer applied unevenly
- Surface not fully clean or dust-free
- Insufficient number of sealer coats
Fix:
- Clean affected area
- Reapply sealer according to instructions
- Ensure even coverage and correct drying time
5. Cracking or Hairline Fractures
Symptoms: Fine cracks appear in base or finish coats.
Possible Causes:
- Substrate movement
- Base coats applied too thick
- Insufficient curing time between layers
Fix:
- Check substrate stability
- Remove cracked area, sand, and reapply base coat
- Follow correct drying times and layer thicknesses
Tips for Prevention
- Always ensure surface stability
- Clean and prep thoroughly before any application
- Follow recommended layer thicknesses and drying times
- Use reinforcement mesh where indicated
- Avoid rushing between coats
Final Note
Most issues arise from skipping prep, rushing coats, or ignoring curing times. By following the MyCROCEMENT™ Application Guide, these problems can usually be avoided.
