The roof of color steel slab house needs to be waterproof. Due to long-term exposure to outdoor bad weather environment, materials with good weather resistance must be used.

聚氨酯防水涂料是由聚醚、异氰酸酯等一系列化学反应形成的聚氨酯预聚体a组分和固化剂B组分组成。使用时，A、B组分按一定比例混合均匀，涂刷固化后形成弹性整体防水胶膜。

Polyurethane waterproof coating is composed of polyurethane prepolymer A and curing agent B formed by a series of chemical reactions such as polyether and isocyanate. When in use, components a and B are mixed evenly according to a certain proportion, and an elastic overall waterproof adhesive film is formed after brushing and curing.

施工要点：

Key points of Construction:

1.基础表面处理：建筑基础表面应坚固、平整、无粉尘。不得填平油污、凹面和损坏的零件。

1. Foundation surface treatment: the building foundation surface shall be firm, flat and free of dust. Oil stain, concave surface and damaged parts shall not be filled.

2.配料：按A组分：B组分=1:2的比例，先将材料A放入容器中，再加入材料B，搅拌均匀后使用。

2. Ingredients: according to the ratio of component A: component B = 1:2, first put material a into the container, then add material B, mix evenly and then use.

3.施工：涂料施工通常分两次进行。用橡胶刮刀或棕色刷子将混合后的涂料均匀地涂在基层表面。需要厚度应一致，并确保涂层在基底表面的渗透和粘合。一道涂层表面干燥后，可施涂二道涂层并进行刮涂，二道涂层的刮涂方向应与一道涂层的刮涂方向垂直。

3. Construction: coating construction is usually carried out in two times. Apply the mixed coating evenly on the base surface with a rubber scraper or brown brush. The required thickness shall be consistent and ensure the penetration and adhesion of the coating on the substrate surface. After the surface of one coating is dry, two coatings can be applied and scraped. The scraping direction of the two coatings shall be perpendicular to the scraping direction of one coating.

4.如果在制备的薄膜中产生气泡(通常由基底表面的高含水量引起)，则应切割起泡处以排出水分，然后在干燥后用油漆进行修补。

4. If bubbles are generated in the prepared film (usually caused by the high water content of the substrate surface), the bubbles shall be cut to drain the water, and then repaired with paint after drying.

济南彩钢板房屋顶防水材料使用聚氨酯防水涂料，因为其防水性能相较于其他材料更好，使用时间也更长。

Polyurethane waterproof coating is recommended for the roof waterproof material of Jinan color steel slab house, because its waterproof performance is better than other materials and its service time is longer.
