Construction Conditions

Base Surface Requirements: To ensure a flawless application of our Reliable Waterproofing with Rapid Curing Hot Spraying Polyurea Liquid, the concrete base surface must be meticulously cleaned, with any imperfections repaired and smoothed to an optimal roughness. It's crucial that the concrete curing process is complete, achieving a strength of C25 or above, and maintaining a moisture content below 8%. Following these preparations, proceed immediately with the next phase to maximize the product's performance.
Environmental Temperature and Humidity Requirements: Our product thrives in a construction environment where temperatures range from 5~35 ºC, ensuring the base surface temperature is consistently at least 5 ºC above the surrounding air's dew point. This precision is key to achieving the desired results. Humidity Range and Ventilation Conditions: The ideal humidity range falls between 30% and 80%, creating the perfect balance for application. It's essential to maintain good ventilation during the application process, while avoiding work during periods of strong wind to ensure the integrity and finish of the waterproofing system.

Operation Methods Requirements

Base Surface Specifications: Ensure that the concrete base surface is meticulously cleaned, repaired to a smooth finish, and polished to achieve optimal roughness. Confirm the completion of concrete curing, with strength reaching at least C25, and a moisture content below 8%. Once the base surface is prepared, promptly proceed to the subsequent process to maintain quality.
Environmental and Humidity Parameters: Maintain the construction environment temperature within the range of 5~35 ºC, while ensuring the base surface temperature is a minimum of 5 ºC above the air dew point temperature; This ensures optimal application conditions. Humidity and Ventilation Standards: Control humidity levels between 30% and 80%. Ensure proper ventilation throughout the construction phase; however, abstain from construction activities during strong winds to maintain work integrity.

Mixing Instructions: Thoroughly combine component B of the coating before use, maintaining a strict A: B volume ratio of 1:1. It is imperative that professional construction teams utilize specialized spraying equipment, with material temperatures consistently managed between 50~80 ºC for premium results.
Process Continuation: Generally, the subsequent process can commence approximately 12 hours after painting. If the construction interval surpasses 24 hours, an interface agent application is necessary. Weather Contingencies: In the event of adverse weather conditions such as rain post-coating, apply a layer of interface agent before proceeding to the next phase to ensure coating integrity.
Curing Standards: For optimal performance, allow the paint film to cure for a minimum of 7 days post-application, ensuring peak performance and durability.
