Spray polyurea waterproof coating is a spray type two components elastic coating composed of components A and B. Component A is a semi prepolymer prepared by the reaction of isocyanate with oligomer Diol or ternary alcohol, and component B is composed of amino terminated resin, hydroxyl terminated resin, amine chain extender, pigment and additives. Elastic polyurea material formed through on-site spraying with professional equipment. This product has excellent mechanical properties, medium resistance, outdoor aging resistance, and excellent adhesion.

Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed, the strength reaches C25 or above, and the moisture content is less than 8%. After processing the base surface, the next process should be carried out as soon as possible.
Environmental temperature and humidity requirements: The construction environment temperature should be between 5~35 ºC, and the base surface temperature should be at least 5 ºC higher than the air dew point temperature; The humidity range should be between 30% and 80%. Ventilation conditions: Ventilation should be maintained during construction, but construction should not be carried out when there is strong wind.
