Preparation of the basis:
Conduct a visual and instructional assessment of defective areas of concrete to calculate the required amount of materials. Clean the damaged areas from structurally weak concrete of other contaminants, preventing adhesion of the mortar to the surface of the repaired concrete. When the reinforcing bars are bare, it is ne- cessary to remove the concrete around them by at least 15 mm. In the presence of active leaks, it is necessary to eliminate them with a dry mixture of ARENA PlugMix PW "Hydraulic plug"
Attention! Before applying ARENA RepairMaster R300, it is necessary to moisten the substrate with water to the maximum possible saturation.
PREPARATION OF SOLVENT MIXTURE:
Work should be carried out at a temperature not lower than -5°C.
Attention! Use only clean water and packaging to prepare the mortar. To prepare such volume of a mortar mix which can be developed within 40 minutes from the moment of mixing with water.
The optimum temperature of the mixing water is 20°C. When the temperature decreases, the time for setting the solution mixture increases and the final strength of the solution decreases. When the temperature is increased, the time for grasping is reduced. On 1 kg of a dry mixmix it is required 0,18-0,19 l of water. It is best to mix with a low-speed drill. Mix for 3 minutes before forming a homogeneous plastic mass without lumps. Dissolve the mortar during use to maintain the original consistency. Re-addition of water to the solution is not allowed.
Before applying the mortar mixture, the concrete surface of the area to be repaired should be thoroughly moistened. Depending on the amount of work, the mortar can be applied with a trowel, a spatula manually or by wet-rolling. The optimum layer thickness of the applied material is 10 mm. The subsequent layers can be applied after 60-120 minutes beforehand. The overpayment of the repair mixture on large areas must be done on a masonry net.
CARE OF PROCESSED SURFACE:
It is necessary to ensure that the treated surfaces remain moist for 3 days. For what you need to moisturize the surface 2-3 times a day.
