Application Procedure
1. Surface Preparation
Remove dust, grease, oil, loose particles, and deteriorated concrete. Damaged areas should be cleaned thoroughly, and smooth surfaces should be roughened where necessary to ensure proper adhesion.
2. Mixing
Mix one 25 kg bag with 4.0–4.5 liters of clean water using a low-speed mixer until a homogeneous consistency is achieved. Allow the mixture to rest briefly before remixing.
3. Application
Apply the prepared mortar using a trowel or spatula. The maximum recommended application thickness is 50 mm. For thicker repairs or larger surfaces, apply in multiple layers.
4. Curing
Protect the repaired surface and keep it moist for at least 24 hours after application to ensure proper curing and optimal strength development.
Application Recommendations
- Mix only with clean water.
- Do not apply at temperatures below +5°C.
- Use the mixed mortar within approximately 30 minutes.
- Prevent standing water on the substrate during application.
- Remove corrosion from reinforcing steel before repair using appropriate preparation methods.
Conclusion
WEBEREP MA 200 is a reliable structural repair mortar offering outstanding strength, excellent adhesion, and superior water resistance. Whether used in new construction, rehabilitation, or maintenance projects, it provides durable and long-lasting concrete repairs that meet professional performance requirements.
