Many friends are asking, can waterproof coating be used to solve roof leakage? After all, many advertisements online claim that waterproof coatings come with a 50 year warranty, which sounds very tempting. And the application of waterproof coating is indeed convenient, it can be directly rolled or brushed with a pig brush for a few times. Ordinary roofs can be fixed in a day, but people are worried about poor waterproofing and short service life. Let’s talk about this topic in detail today~
What are the common roof waterproof coatings?
This is a waterproof coating specifically designed for roofs and rooftops, with good weather resistance and can be directly exposed for use. It is commonly used for roofs with complex structures.
This coating has good performance in all aspects, but it is not suitable for small area use and is prone to delamination, so it is not recommended.
This is quite controversial. Many people mistakenly believe that polyurethane coatings can be directly exposed for use, but this is actually a misconception. Except for property management, most professional waterproofing companies do not use polyurethane waterproof coatings externally.
Is it reliable to apply paint directly for roof leaks?
In fact, it is easy for roof leaks to occur again if they are directly coated. Firstly, there is a problem with the material itself. Waterproof coatings typically age within three to five years, while waterproofing membranes may not completely age for ten years, which does not affect the waterproofing effect. Secondly, some roof leaks cannot be solved by paint, which is why it is difficult for property management to fix them with paint.
summary
If your roof leaks, applying waterproof coating directly may not be the best choice. Although the construction is convenient, the effect and lifespan are not as good as waterproofing membranes. Waterproof coatings are prone to aging, and some water leakage problems cannot be solved by coatings. It is recommended that when choosing a waterproof solution, everyone should consider comprehensively and choose the most suitable waterproof material for their home.
