Construction method for sticking SBC water-proof coiled material by JS composite water-proof paint

Abstract

The invention relates to a construction method for JS composite underwater paint to stick SBC waterproof coiled material, the construction steps are as follows: (1) construction surface is treated; (2) liquid material and powder material of the JS composite underwater paint are mixed and stirred evenly, then are painted on the construction surface and stuck with the SBC waterproof coiled material, so that the SBC waterproof coiled material forms a layer of waterproof additional layer through sticking; (3) the liquid material and the powder material of the JS composite underwater paint and water are mixed and stirred to serosity, then painted on the waterproof additional layer; (4) the liquid material and the powder material of the JS composite underwater paint and water are stirred to the serosity and stuck on a bond coat and then stuck with a layer of waterproof coiled material; (5) positions where leakage is easy to happen such as wall angles, drain gullies, pipe orifices, dilatation joints and so on are covered with a layer of waterproof additional layer according to the step (2); (6) finally the liquid material and the powder material of the JS composite underwater paint and water are mixed and stirred evenly to serosity, then painted a layer of protective layer on the upper surface of the coiled material. The construction method of the invention can effectively make up for defects caused by crackles or holes of a foundation course, strengthen cracking resistance, improve waterproof effect and reduce the cost.

Description

Technical field: [0001] The invention relates to a roof waterproof covering layer, in particular to a construction method for pasting SBC waterproof coiled materials with JS composite waterproof paint. Background technique: [0002] The current JS composite waterproof coating, also known as JS polymer cement-based waterproof coating, is mainly used for waterproofing of roofs, kitchens, and bathrooms. It is composed of emulsion and powder, and the emulsion is acrylate emulsion or VAE emulsion. The main material is made by adding an appropriate amount of plasticizer, dispersant, preservative, and foam clearing agent. The powder is made of ordinary Portland cement or sulphoaluminate cement as the main material and water-reducing agent. The current SBC waterproof membrane is composed of a certain thickness of polyethylene film and polypropylene cloth or polyester cloth. It is used for roof waterproofing, underground waterproofing, anti-seepage engineering, etc. The construction ...

Problems solved by technology

Although this construction method has the advantages of simplicity and low cost, the disadvantage is that the initial adhesion of this cement slurry is small, and the softness of the SBC waterproofing membrane is limited, and the surface of the base is uneven, which leads to poor adhesion during laying. During the process, the phenomenon of "drumming" and "virtual sticking" often occurs, and it is easy to crack at the overlapping joints of the coils, which reduces the construction quality and waterproof effect
