MC Nisiwa- SH

Nisiwa-SH Silicone based, ready to use, colourless, hydrophobic impregnation with deep penetrating property Application Notes General Nisiwa-SH is a silicone based, ready to use, colorless hydrophobic impregnating coating with deep penetrating properties. Nisiwa-SH protects the exterior masonry reliably against the penetration of moisture to interiors despite pelting rains. Through this process of prevention of transfer of moisture to interiors, an efficient waterproofing and damp proofing is obtained during spring as well as winter seasons. Nisiwa-SH does not affect the breathing capacity of impregnated surfaces. It is suitable for application on almost all types of common building materials. It is suitable for porous substrates as well as substrates with a slight absorption properties. Instructions for use Preparation of base The substrate must be sound, dry and free from other contamination. Plasters should be at least 14 days old. The cracks and other defective spots in the bases should be rectified before application of Nisiwa-SH. Handling Nisiwa-SH can be applied by means of soft brushes or by spraying. Only one coat of sufficient material per application is enough to achieve an excellent impregnation. While using spray application it is suggested to also cover the neighboring areas, including those that are not to be impregnated. In case of bases exhibiting high absorptive tendencies two coats are necessary for achieving good impregnation. When glazed, sintered or non-absorptive surfaces are to be impregnated, a preliminary trial should be carried out to check the efficiency of the application. It is also recommended to run preliminary trials where there is a possibility of strong dusting on impregnated surfaces during the process of application or when the coat is wet. Consumption The consumption of Nisiwa-SH depends upon the quality and absorptive capacity of the surfaces to be impregnated. Approximately the consumption is in the range of 150 gms/m2 per coat. If a second coat of Nisiwa-SH is necessary, it should be ensured that the prior coat of Nisiwa-SH should be thoroughly dry. Product Properties • Optimum protection of facades from pelting rains and precipitation moisture by virtue of deep penetrating capacity • Water based and solvent free • Possesses deep penetrating effects and is delivered in ready-to-use consistency • Does not seal surface pores and maintains the original breathing capacity of concrete • Leaves interiors dry under all weather conditions • Prevents damage of masonry exposed to aggressive atmosphere especially by frost • Prevents efflorescence and checks moss and fungus growth • It has good penetration capacity on low absorption surfaces as well as on fine-pore or moist (not wet) surfaces • It is effective 1 to 2 hours after application. The impregnation with Nisiwa -SH is unaffected by rains • It does not bring about change in colour or structure of impregnated areas • It shields effectively the facades against dust and soot. • It provides long lasting and durable impregnation to facades supplemented by water repelling properties
