Comparison of waterproof coil and waterproof coating

Due to the difference in material composition and appearance form of waterproof coil and waterproof coating, the characteristics, construction technology, applicable parts and application environment of the material are different. The following is a comparison of the comprehensive performance of the two, through the comparison to let consumers roughly understand what kind of products they need.

Advantage

Waterproof coil

(1) Convenient construction, short construction period, no maintenance after forming, not affected by temperature, small environmental pollution.

(2) The layer thickness is easy to grasp according to the design requirements, the material calculation is accurate, the construction site management is convenient, and it is not easy to cut corners.

(3) The thickness of the layer is uniform, and the stress of the base can be effectively overcome when the base is empty (the integrity of the waterproof layer can be maintained when the base has a large crack).

Waterproof coating

(1) Any complex base can be made into a continuous overall waterproof layer, simple equipment, construction technology is easy to master.

(2) The waterproof coating layer and the base layer have a 100% bonding surface (except for cracks, joints and other parts of the reinforced layer empty paving method).

(3) The water leakage of the coating waterproof layer in the service life, mostly for the base cracking width exceeds the extension of the waterproof coating, the cause of water leakage and the formation of water leakage parts are easy to find, the warranty is very convenient, as long as a small amount of waterproof materials to repair cracks and damage parts.

(4) high-quality waterproof coatings can be successfully waterproof on the back surface, and some waterproof coatings can be constructed on the wet base and form a waterproof layer.

Shortcoming

Waterproof coil

(1) It is necessary to measure and cut clothes according to the shape of the waterproof base, for the complex shape of the base, it is necessary to splice multiple pieces, and the bond at the joint of the waterproof coil is more difficult.

(2) Complete and absolute sealing will become the main problem, the biggest potential water leakage.

(3) The protection of waterproof coil after construction and maintenance after water leakage is also a problem, any part of the damage, degumming, leakage (even if it is only one), the waterproof function of the whole coherent level will all fail, if you can not find the damage and defect parts, then the local repair is impossible, then only rewaterproofing.

Waterproof coating

(1) The coating needs a certain time of physical and chemical reaction consolidation to produce a waterproof layer, some waterproof coatings in the curing process to produce harmful gas release, harmful to the human body.

(2) The completion of a waterproof layer of some waterproof coatings requires multiple brushes, and each brush must have a certain interval, so the final completion of the waterproof layer will take a longer time.

(3) In the construction process of waterproof coating, site management is very important, jerry-cutting, shoddy production in the case of management negligence will have opportunities to take advantage of.

(4) The thickness of the coating waterproof layer is determined by 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.
