Comparative analysis of advantages and disadvantages of waterproof coiled materials and waterproof coatings
Due to the difference in material composition and appearance of the waterproof coiled material and the waterproof coating, the characteristics of the material, the construction process, the applicable parts, and the application environment are different. Deco waterproof engineers compared the overall performance of the two, and let consumers know what products they need by comparison.

advantage:
Waterproof membrane material - convenient construction, short construction period, no need for maintenance after forming, no temperature influence, small environmental pollution, layer thickness is easy to master according to design requirements, accurate calculation of materials, convenient construction site management, easy to cut corners, uniform thickness, empty It can effectively overcome the stress of the base layer when paving (maintaining the integrity of the waterproof layer when large cracks occur in the base layer).
Waterproof coating - any complex base layer can be made into a continuous overall waterproof layer; the equipment is simple and the construction technology is easy to master. The waterproof layer of the coating and the base layer have a bonding surface of 100% (except for cracks, joints, etc., except for the use of the reinforcement layer. The water leakage of the coating waterproof layer during the serviceable period is mostly that the cracking width of the base layer exceeds the extendable range of the waterproof coating. The cause of water leakage and the part forming the water leakage are easily found. The warranty is very convenient, as long as a small amount of waterproof material repairs the crack and the damaged part. can. High quality waterproof coatings are available for waterproofing on the back surface. Part of the waterproof coating can be applied on a wet base and form a waterproof layer.
Disadvantages:
Waterproof membrane material - it needs to be cut according to the shape of the waterproof base layer. For the complex base layer, multiple pieces of splicing are required. It is difficult to bond the waterproof coils to each other; completely absolute sealing will become a major problem. The leakage of water is the biggest hidden danger; the protection of the waterproof membrane after construction and the maintenance after water leakage are also difficult problems. The penetration of any part is broken, degumming and leaking (even if there is only one place), and the waterproof function of the whole connected layer All will be lost, if the damage and defective parts can not be found, local repair is impossible, then only redo waterproof.
Waterproof coatings - coatings require a certain period of physical and chemical reaction to form a waterproof layer after consolidation; some waterproof coatings produce harmful gases during the curing process and are harmful to the human body. Some waterproof coatings need to be painted many times for the completion of a waterproof layer. Each time there is a certain interval between paintings, the final completion of the waterproof layer takes a long time; during the construction of waterproof coating, on-site management is very important. Cut corners and rough shoddy will be organic in case of management negligence; the thickness of the coating waterproof layer is determined according to the number of coating passes during construction. In addition to the number of coating passes, the solid content of the coating itself is the determining factor of film thickness.
