The cost and cost of polyurethane waterproofing in the bathroom

Looking at the product packaging instructions, generally speaking, it takes 2 dosages per square meter to brush 2mm thickness, so a set of 30 kg can only brush 12 15 square meters.

For example, if the price of a 30kg set is 150 yuan, and 15 square meters can be painted, then each square meter is 10 yuan.

10 20 pieces, there is naturally a price difference between the quality of the material. How can the bathroom be made polyurethane waterproof? The two-component one is better!
