Cement Based Plastering Render Repair Mortar With High Strength

Product features:

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.

Scope of 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.

Construction technology:

Base treatment: Before construction, cut into the maintenance scope about 10 mm with cutting machine, chiseling all loose concrete away, remove rust iron thoroughly, and remove dust on the surface of the concrete, And then coated with repair mortar interface agent on the steel surface. If the base plane is dry completely before plastering repair mortar, must be clean with water thoroughly and plaster again, and then can plaster the repair mortar.

Stirring: mix mortar with quantitative water (add water gradually), stirring with the right type of blender mixing about 5 min, until evenly without block.
Construction: Put and overwhelm the repair mortar with a spatula or with artificial construction directly on the base plane of the coating interface.

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.
