Characteristics of anti-crack mortar
Anti-cracking mortar is a building material mixed with cement, lime, sand, polymer, and other materials. It has the following characteristics:
High strength: Anti-cracking mortar has high tensile strength and compressive strength, which can effectively bear the load of the building and ensure its safety of the building.
High cohesion: The anti-cracking mortar has strong cohesion and can be firmly bonded to the surface of the building without peeling off.
Good anti-seepage performance: Anti-crack mortar has good anti-seepage performance, which can effectively prevent water penetration and protect the walls of buildings from being eroded by water.
Good crack resistance: anti-crack mortar has strong crack resistance, which can effectively prevent cracks in buildings.
Good durability: The anti-crack mortar has good durability and can maintain a long service life.
How to use anti-crack mortar
Preparations: Before construction, dust and oil stains on the surface of the building need to be removed to ensure that the surface is dry and clean.
Mixing: Mix anti-cracking mortar and water according to a certain ratio, and mix well with a mixer or hand mixer until there are no solid particles.
Brushing: Use a brush to evenly paint the anti-cracking mortar on the surface of the building, and the thickness of each brush should be controlled between 1-2 mm.
Maintenance: After the construction is completed, it is necessary to maintain the painted anti-cracking mortar to ensure that it is dry and solidified. Generally, it needs to be maintained for 3-5 days.
Precautions for anti-crack mortar
Mixing according to the specified ratio: When using an anti-cracking mortar, it needs to be mixed according to the specified ratio to avoid excessive or too little water, which will affect the quality of the anti-cracking mortar.
Uniform brushing: When painting anti-cracking mortar, it is necessary to paint evenly to avoid missing brushes or uneven thickness and thickness.
Control the thickness of the painting: the thickness of the anti-cracking mortar should be controlled between 1-2 mm each time, to avoid excessive thickness affecting its adhesion and curing time.
The curing time should be sufficient: the anti-cracking mortar needs to be cured after construction to ensure that it is fully dry and solidified. Generally, it needs to be cured for 3-5 days, otherwise, the quality of the anti-cracking mortar will be affected.
Precautions for storage: Anti-cracking mortar needs to be stored in a cool and dry place, avoid direct sunlight and high-temperature environment, so as not to affect its quality.
As a commonly used building material, anti-crack mortar has good crack resistance and cohesive force, which can effectively improve the durability and safety of buildings. When using an anti-cracking mortar, it is necessary to pay attention to mixing according to the specified ratio, uniform brushing, control of brushing thickness, and sufficient curing time to ensure its quality. Reasonable use of anti-crack mortar can effectively prevent cracks in buildings and improve the quality and safety of buildings.
