Coarse grain repair Dexter
Coarse-grained remover is a kind of cement-based powder that has the ability to form and adhere to a variety of materials, especially concrete, due to the presence of various polymers for concrete adhesives and fibers in its structure.
Coarse-grained repairer is based on the following standards:
ASTM C928, ASTM C1583
BS EN 12636, BS EN 12637
Coarse-grained repair features:
Extremely high adhesion to a variety of materials
Can be used on cement and concrete surfaces
Can be used on internal and external surfaces
Easy to run
Suitable mechanical strength
Resistant to heat and cold cycles
Increase the impermeability of concrete surfaces
Ability to supply in different colors depending on customer needs
Uses of coarse grain repair:
Repair and leveling of porous surfaces with a depth of more than 3 mm
Leveling unevenness caused by formatting errors
Can be used on surfaces that are in direct contact with water.
Execution of cement muscles up to a maximum thickness of 2 cm
Repair cracks with a depth of more than 3 mm of concrete and cement surfaces
Consumption of coarse grain repair:
Depending on the amount of porosity and unevenness of the applied surfaces for covering one square meter with a thickness of 3 mm to 20 mm can be calculated depending on the density.
This product is not recommended for thickness less than 2 mm, and if you use this product for thickness more than 2 cm, be sure to consult with our experts.
Steps of using coarse grain repair method:
The surface must be clean, firm and free of grease, dust, paint, oil and loose particles.
About 4.5 to 5 liters of water should be added to each 25 kg bag. Mixing the powder with water should be done using an electric mixer. Always add the powder slowly to the water and make sure that the electric mixer is on when the powder is added to the water and that the mixing process continues until a uniform and homogeneous mixture is obtained.
Be sure to moisten the substrates before applying the prepared mixture.
Apply the prepared mortar with a trowel or spatula on wet surfaces.
Always mix the amount of powder with water to be used in less than 20 minutes at most.
After the mortar is half dry, keep all surfaces moist by spraying water for at least 24 hours.
