Waterproof coating is permeable and bonded, with good elasticity and long service life. If the roof information is special, such as rubber, which is not suitable for waterproof coating, you can choose other waterproof information. Such as waterproofing agent, if it is the appearance of ceramic tile, it will not continue to crack, and it can be used to waterproof the surface, and the gap can be combined with caulking paste.

2. If the SBS waterproofing membrane has been paved for more than 67 years, the appearance is seriously damaged, so SBS can only be paved again. If the time is short and the damage is not very serious, then buy one or two barrels of oily polyurethane waterproof coating and re-alter the damaged parts, so that it can be used for two or three years, saving time, money and labor.

3. The leaking points of the roof are usually external places such as water outlets and joints. These details must be handled well during construction, which will be much safer. The self-management effect is not good, and the later protection is troublesome, which affects the overall effect. If in doubt, you need to find a professional maintenance team to deal with it. In a word, roof leakage should be fully implemented.
