Construction waterproof Render Repair Mortar / concrete repair mortar

Feature:
1. Extremely low water demand, have good early strength.
2. Excellent bonding power, reduce the old and new mortar's stripping.
3. High density, good waterproof performance. Reduce permeability of chloride and carbon dioxide, protect building's main structure effectively.
4. Low shrinkage, reduce cracking.
5. Easy construction so that improve the efficiency.
6. Non-toxic and tasteless, it does not contain solvent, inflammable.
Application :
It’s suitable to repair concrete exfoliation caused by reinforcement corrosion; repair the structural defects or concrete components part; fill in the gap between the decorative window.
Stirring: mix mortar with quantitative water (add water gradually), stirring with the right type of blender mixing about 5 min, until evenly without block.
Attention:

1. Should clean and wet the base plane before construction.
2. The stirred slurry should be finished within 4 hours.
3. Avoid construction below 5 ℃, 40 ℃ above environment.
4. The layer is completed, should be natural maintenance more than 3 days, can do the next working procedure construction.
5. Don’t use the dried paste by re-adding water.
