Description
M-CRETE 100 – Lightweight Epoxy Concrete Repair Mortar
Is formulated using solvent free epoxy resins and lightweight fillers. The product is designed for the long term repair of spalled and damaged concrete.
Due to the low mixed weight of the material is perfectly suited for vertical and overhead concrete repairs or to repair damaged stone.
The mixed material has a very high build capability of up 50.0mm in a single application.
This helps to reduce the application time and repair cost considerably, versus conventional repair methods.
Any exposed reinforcing bar will need to be prepared and treated with a primer such as M-PRIME 200 – Metal Surface Primer to stop further corrosion and spalling.
.
Typical Uses
- Reinforced Concrete Lintel Repair
- Concrete Windowsill Repair
- Concrete Column Repair
- Damaged Stonework
- Cosmetic Repairs to Bridges and Concrete Structures

Application Guide
- The concrete surface must be free of all dust and loose materials, compressed air can be used to clean any thin hairline cracks or deep pitting.
- For oil contaminated surfaces an enzyme cleaner must be applied to the surface to ensure that all residual oil contamination is removed.
- The concrete can be abraded using a mechanical grinder to ensure the repair material is adhering to a sound concrete surface.
All repair surface must be primed
- Pour the primer (activator) component into the primer (base) component tin and mix with the spatula provided.
- Once the resin is streak free apply by brush to the repair area.
- Ensure the primer is pressed into any cracks or pitting and the concrete surface is thoroughly wetted.
Prior to mixing please ensure the following:
- The material components are at a temperature between 15-25°C.
- The ambient & surface temperature is above 10°C.
- The ambient & surface temperatures are not less than 3°C above the dew point.
- Transfer the bag of aggregate (aggregate is pre-mixed with the based component) into the 5ltr, tin provided and then add the activator component to the aggregate.
- For the best results use an electric paddle mixer to ensure the two components are thoroughly mixed.
By Hand
- Once mixed best application method is by forcing the material in to the repair with a gloved hand and finishing with a float to achieve the required surface finish.
- For overhead or vertical surfaces, the material can be applied up to 50mm using melamine boards as temporary shuttering to support the mortar whilst curing.
- For best results spray water onto the face of the trowel for the finishing skim.
