Waterborne polyurethane floor paint and waterborne epoxy floor paint are similar in use, but waterborne polyurethane floor paint can be used outdoors, while waterborne epoxy floor paint is mostly used indoors, and waterborne polyurethane floor paint has sunscreen characteristics. Both can be dust-proof, skid-proof, wear-resistant, pressure-resistant, seamless, easy to clean, corrosion-resistant and other characteristics. There are also similarities in construction technology, polyurethane flooring and water-based epoxy flooring have the same construction technology, but the materials are different. 

1、基礎地面打磨清理，裂縫、凹坑、起皮、起砂等現象處理；

1. Ground grinding and cleaning, cracks, pits, peeling, sand and other phenomena;

2、涂刷底涂，涂量要足；

2. The amount of undercoat should be adequate.

3、刮涂無溶劑中涂砂漿；先找補再整體刮涂一道；待完全固化后精細打磨一道；

3. Scraping and painting with mortar in solvent-free medium; first looking for repairs and then scraping together as a whole; after complete solidification, fine grinding together;

4、刮涂膩子，用于封塵；

4. Scrape and coat putty for dust sealing.

5、刮涂一道聚氨酯面漆，再滾涂一道水性聚氨酯面漆即可。聚氨酯地坪可以在水性環氧地坪上做，反之水性無錫環氧地坪不能在聚氨酯上做。

5. Scrape a polyurethane topcoat and roll a waterborne polyurethane topcoat. Polyurethane flooring can be made on waterborne epoxy flooring, whereas waterborne epoxy flooring can not be made on polyurethane flooring.

水性聚氨酯耐磨性能十分好，具有耐潮濕及防滑、耐嚴苛化學品腐蝕、耐重載及強沖擊、環保無污染等優點，使用壽命長達20年以上，耐-40℃-130℃高低溫，可廣泛應用于食品、屠宰、重防腐、高濕高溫等極端工作環境下之地面處理，和所有須耐磨、潔凈、耐化學品等車間、倉庫、停車庫、試驗室等地面，具有傳統地坪涂料如環氧、金剛砂地坪等不可比擬的優勢。

Waterborne polyurethane has excellent wear resistance, such as moisture resistance, skid resistance, corrosion resistance of severe chemicals, heavy load resistance, strong impact resistance, environmental protection and pollution-free. Its service life is over 20 years, and it can withstand high and low temperatures ranging from - 40 C to 130 C. It can be widely used in extreme working environments such as food, slaughtering, heavy corrosion protection, high humidity and high temperature. Processing, and all workshops, warehouses, parking garages, laboratories and other floors that must be abrasive-resistant, clean, chemical-resistant, has incomparable advantages of traditional floor coatings such as epoxy, diamond sand floors.
