Surface preparation : 1. Surface preparation: use polisher & dust collection machine to polish the concrete panel and then clean the dust; it should be polished, repaired, dust collected according to the site basic ground condition;and then apply primer evenly,to cover the rough part; Correct substrate preparation is critical for optimum performance. Surface should be sound, clean, dry and free from loose particles, oil, grease, and other contaminants; 2. Primer is a single-component product, open lid can be used directly; rolling or spraying evenly at 1 time; 3. Polyurethane waterproof paint is a single-component product also, open lid can be used directly; rolling or spraying evenly at 1 time; 4. Inspection standard for the top coating: Non-sticky to hand, no softening, no nail print if you scratch the surface.Application Step

Construction Conditions The construction conditions should not be in moisture season with cold weather (temperature is ≥10℃ and humidity is ≤85%). The below application time refers to normal temperature in 25℃.Cautions : 1) The mixing paint should be used within 20 minutes; 2) Maintain 5 days after finished, can be walked on when floor is solid absolutely, maintain 7 days could be used; 3) Film protection: keep away from stepping on, rain, exposing to sunlight and scratching until the film is fully dried and solidified; 4) You should make an small sample before large-scale application.I suggest that you can find a 2M*2M places in the corner of the construction site to apply it.Notes: he above information is given to the best of our knowledge based on laboratory tests and practical experience. However, since we cannot anticipate or control many conditions under which our products may be used, we can only guarantee the quality of the product itself. We reserve the right to alter the given information without prior notice.    Practical thickness of the paints can be little different from the theoretical thickness mentioned above due to many elements like environment,application methods,etc.Versatility One-component polyurethane waterproof coatings are also widely used. It can be used on a variety of surfaces including concrete, metal and wood, making it ideal for a variety of projects. Low odor Unlike some other types of waterproofing, one-component polyurethane waterproofing is low in odor. This makes it a safer choice for indoor projects as there is less risk of harmful fumes. Overall, one-component polyurethane waterproofing coatings are an excellent choice for anyone looking to protect their surfaces from water damage. With its ease of application, excellent water resistance, durability, versatility and low odor, the paint is the ideal solution for a range of projects.
