Construction technology for treating mould wall surface of building

Abstract

The invention discloses a construction technology for treating a mould wall surface of a building. Tools of an electric polishing wheel, a flat spade and the like are used for cleaning an original coating away until a concrete base surface is exposed; peracetic acid is used for sterilizing and disinfecting a wall, before using, after the mixed liquid is placed for 24 h according to the matching ratio of A to B being 10:8, the mixed liquid is diluted to a peracetic acid solution with the concentration of 0.2%-0.5%, the peracetic acid solution is put in a sprayer and sprayed for sterilizing anddisinfecting, and the liquid absorbing amount of the cement wall is 100 ml / m2; after the wall surface is sterilized and disinfected for 4 h, water-proof putty is adopted for scrapping and levelling the wall surface; a first selected coating component is stirred uniformly by adopting a mechanical stirring method, a second component is added according to the proportion marked by a packing bucket, the mixture is uniformly stirred again, and the coating application period is 3 hours; after the levelled base surface is naturally dried for 48 h, alkali-resistant undercoat is brushed, and the using amount of the undercoat is 0.1 kg / m2; specific inspection records should be recorded on each coating. The technology is simple, the appropriate mould-proof treatment of the wall surface can be ensured,after construction, the phenomenon of the mould wall surface cannot repeatedly occur so that the mould-proof quality can meet the requirements, and the service life of the wall body is prolonged.

Description

technical field [0001] The invention relates to a process, in particular to a construction process for treating moldy building walls. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resins have mostly or completely replaced vegetable oils, so they are called paints. Coatings are not liquid, and powder coatings are a large category of coatings. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the class...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned existing complex process for wall surface anti-mildew treatment, and there are repetitions, so that the problem of poor anti-mold effect on the wall surface is designed, and a construction method for processing moldy building wall surface is designed. process, the process of this process is simple, can ensure that the anti-mildew treatment of the wall is in place, and there will be no repetition after construction, so that the quality of anti-mildew can meet the requirements, prolong the service life of the wall, and solve the existing problem of anti-mildew on the wall. The process of mildew treatment is complicated and repeated, which makes the anti-mildew effect of the wall poor.
