Indoor Waterproofing Engineering Materials - Introduction and Construction Methods of JS Composite Waterproof Coating
Release time:
2021-08-30
Synopsis: Indoor waterproofing projects, as an important category in building waterproofing engineering, are mainly divided into rigid and flexible waterproofing methods. Rigid waterproofing has a longer service life, simple construction process, easy material sourcing, convenient maintenance, and good leak-stopping effects, but it has shortcomings in temperature change resistance, making it prone to cracking and water seepage. Flexible waterproofing has high tensile strength, large elongation, lightweight, convenient construction, and can adapt to certain deformations and expansions, making it less prone to cracking. However, it mainly uses organic materials such as asphalt and felt, which are prone to aging and have a short lifespan. Each choice has its shortcomings, but with the development of engineering technology, JS composite waterproofing coatings can address both aspects.

Introduction to JS Composite Waterproofing Coating
JS composite waterproofing coating, also known as polymer cement waterproofing coating, is made from elastic acrylic copolymer emulsion and various high molecular additives using the latest room temperature rapid cross-linking technology. It can be used by mixing with cement in a certain proportion during construction. After application, JS composite waterproofing coating forms a highly elastic and high-strength waterproof film with excellent water resistance, weather resistance, and durability; it is non-toxic, odorless, and pollution-free, can be applied on damp substrates, and can bond firmly with various materials such as substrates and cement mortar, making it easy to operate and simple to construct.
JS Composite Waterproofing Coating Construction Method
1. The substrate must be flat, solid, clean, and free of standing water. Uneven areas must be leveled first, and corners should be rounded.
2. Take materials in the specified proportion and mix thoroughly with an electric mixer until there are no lumps in the mixture.
3. Choose appropriate tools (rollers, brushes, etc.) and complete the layers in the order of base layer → lower layer → middle layer → upper layer according to the corresponding construction method.
4. The mortar protection layer or decorative layer construction must be carried out after the waterproof layer has been accepted. When applying mortar, to facilitate construction, clean medium-coarse sand should be sprinkled immediately after the last coat of the waterproof layer is applied.
The above is the introduction and construction method of JS composite waterproofing coating, hoping to assist the construction teams preparing for indoor waterproofing projects.
