Preparation is crucial before applying PENTENS SPU-1000. First, ensure that the surface is dry, clean, and free of grease, dust, or other impurities. If any cracks or holes are found, they should be repaired in advance to ensure the effectiveness and durability of the waterproof layer. Next, during the application process, a water-based primer should be applied to damp surfaces, which helps enhance the adhesion of the waterproof layer. Ensuring an even application of the primer is the first step to success.
The mixing of materials is equally important. According to the product instructions, the two components of PENTENS SPU-1000 should be mixed evenly. It is essential to choose the appropriate mixing tools to avoid the formation of bubbles, which can affect the final result. Subsequently, use a professional high-pressure spray gun to evenly spray the mixed material onto the surface, maintaining an appropriate distance between the spray gun and the surface to ensure uniformity and thickness of the coating.
After spraying, it is imperative to allow the first layer to dry completely before applying the second layer, based on environmental conditions. Generally, it is recommended that each layer does not exceed a thickness of 1.5 mm to ensure optimal results. Once SPU-1000 has fully cured, a non-yellowing topcoat can be applied, which not only enhances the protective effect but also improves durability. Finally, after completion, a thorough inspection should be conducted to ensure there are no missed areas or weak points, and the waterproof layer’s condition should be regularly checked to ensure its longevity and effectiveness. By following these steps, the excellent construction effect of PENTENS SPU-1000 will be ensured, further enhancing the overall performance of the waterproofing system.
