Concrete restorer GB_R.B12

توضیحات

Description:

At the same time as concreting, mold removal, or after the passage of time, the surface of the concrete gets damaged or frosted, which can be easily restored and restored with concrete repair mortar. For this purpose, there is a need for a mortar for surface changes that, in addition to being made of concrete, has good adhesion. G.B_R.B12 concrete repair powder is formulated from cement, aggregate and polypropylene fibers and resin, which is a very soft and fine-grained powder that enables mortar after mixing with water, which can be easily applied on surfaces. The presence of copolymer resin and polypropylene fibers give the mortar good adhesion and mechanical resistance, and it can be easily applied in different thicknesses. The use of epoxy repair mortars on cement and concrete surfaces is not suitable for the repair of concrete or concrete surfaces with a high depth of damage due to the difference in the coefficient of thermal expansion, because if epoxy repair materials are used in high thickness and volume, we will see cracking and separation.

Physical and chemical state:

Maintenanc:

The above product can be stored for 12 months under standard storage conditions The best temperature for storage is 10 to 20 degrees Celsius

packaging method:

The desired product is offered in 20 kg bags

instructions:

Before applying, clean the surface from any pollution, including dust, fat, oil and loose particles, and if the surface is contaminated, you must first wash and clean the surface completely by sandblasting or water pressure. The presence of any fat on the work surface prevents the surface from bonding to the mortar and its scaling and scaling. To apply the restorer, the bottom surface must be scratched and roughened. If the rebars inside the concrete are visible, the back of the rebars should be emptied so that there is at least 1 cm of space around the rebars for rust removal and filling with concrete repair mortar. If the rebars are corroded, they should be de-rusted by sandblasting. The surface of the rebars should be covered with a layer of primer, if there are aggressive environmental conditions, the surface of the reinforcements should be covered with a layer of zinc-rich epoxy primer

The work surface should be saturated with water. 5 to 6 liters of water are needed for each bag of 25 kg of restoring powder. Make sure that the powder is always added to the water and mixed with an electric mixer (drill and blade) to obtain a uniform mortar. It is recommended to apply a primer layer on the desired surface to increase the adhesion coefficient. Apply the repair mortar on the surface with a trowel or trowel. It is suggested to add 2.5 kg of concrete adhesive to each 25 kg bag of repair powder to improve adhesion and properties. Concrete restorer is not capable of completely removing moisture and leakage or sealing the surface, and if the purpose of concrete repair is to seal the surface, special sealing materials should be used.

Hints : Always mix the amount of powder into the mortar that will be used for up to 30 minutes. If the repair is done in several layers, the time interval between two layers should be at least 3 hours, the lower layer should be slightly roughened with a spatula. In the early hours of implementation, the applied mortar should be prevented from direct sunlight, freezing or any aggressive environmental factors, and it should be cured for 48 hours, and if there are unusual environmental conditions, it should be protected by a wet sack and plastic.

Safety items:
