Abstract
The invention discloses a waterproof and antifouling construction method for an external wall, which comprises the following steps: s1, cleaning the wall surface, and drying; s2, repairing hollowing, cracking and falling parts, repairing gaps with special mortar and waiting for drying; s3, directly spraying waterproof and antifouling agents; and S4, drying for 24 hours, and spraying water for acceptance. According to the invention, the hollowing, cracking and falling parts are repaired before the waterproof antifouling agent is sprayed, so that the waterproof and antifouling effects after spraying are improved.
Description
Technical Field
The invention relates to the technical field of waterproof and antifouling construction methods, in particular to a waterproof and antifouling construction method for an outer wall.
Background
When the outer wall is subjected to waterproof and antifouling construction, a direct spraying mode is often adopted, and hollowing, cracking and falling parts on the surface of a wall body are not repaired before spraying, so that the waterproof and antifouling effect after spraying is poor.
Disclosure of Invention
The invention aims to provide a waterproof and antifouling construction method for an outer wall, which aims to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a waterproof and antifouling construction method for an outer wall comprises the following steps:
s1, cleaning the wall surface, and drying;
s2, repairing hollowing, cracking and falling parts, repairing gaps with special mortar and waiting for drying;
s3, directly spraying waterproof and antifouling agents;
and S4, drying for 24 hours, and spraying water for acceptance.
Preferably, the waterproof antifouling agent is a CPC multifunctional composite waterproof antifouling agent.
Preferably, the coating rate of the waterproof and antifouling agent is 10 m/l.
Preferably, the drying mode is natural air drying.
Preferably, before the step S3, an application test is performed on the surface to be subjected to waterproofing and antifouling construction.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, the hollowing, cracking and falling parts are repaired before the waterproof antifouling agent is sprayed, so that the waterproof and antifouling effects after spraying are improved.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Examples
The invention provides a technical scheme that: a waterproof and antifouling construction method for an outer wall comprises the following steps:
s1, cleaning the wall surface, and drying;
s2, repairing hollowing, cracking and falling parts, repairing gaps with special mortar and waiting for drying;
s3, directly spraying waterproof and antifouling agents;
and S4, drying for 24 hours, and spraying water for acceptance.
Specifically, the waterproof antifouling agent is a CPC multifunctional composite waterproof antifouling agent, and the silane nano active content reaches 82%, so that the waterproof antifouling agent is a water-based environment-friendly permeable transparent waterproof solution). The small molecular structure can penetrate through the cementing surface, penetrate into the tile, any natural stone and concrete, and chemically react with the air exposed in the acidic or alkaline environment and water molecules in the substrate to form a hydrophobic treatment layer, so that the moisture is inhibited from entering the substrate. Resulting in water-repellent, Cl-, UV-resistant properties and excellent breathability. Can effectively prevent the base material from corroding, loosening, stripping and mildewing the concrete and the internal reinforcing steel bar structure due to water seepage, sunshine, acid rain and seawater erosion to cause seepage and pathological changes, and prolongs the service life of the building. The protected substrate has good water repellency and retains its original appearance. An alkaline environment, such as concrete soon as it is poured, stimulates this reaction and accelerates the formation of a water repellent layer.
Specifically, the coating rate of the water-and soil-repellent agent was 10 m/l.
Specifically, the drying mode is natural air drying.
Specifically, the spraying mode is through a sealed spray gun.
In other embodiments, the spray application is by a spray application.
Specifically, before step S3, an application test is performed on the surface to be subjected to waterproof and antifouling construction, so as to ensure compatibility and achieve an ideal waterproof effect.
The working principle is as follows: [ construction conditions ]
a. The climbing equipment meets the safety requirements;
b. during construction, an operator wears a working garment, brings a safety helmet and a protective tool, ties a safety belt, implements all safety measures, and constructs strictly according to an operation program;
c. the construction site keeps good ventilation and is equipped with necessary illumination, so that the construction safety is ensured;
d. the materials and machines are stacked orderly, and the protection measures for greening, doors and windows and other building accessories are implemented in place, so that the civilized construction is realized;
e. when a roller and a paint brush are selected for brushing, the roller and the paint brush should roll back and forth for a circle on the dentate plate or add materials at the edge of the barrel after dipping each time, so as to reduce waste and avoid environmental pollution;
f. the coating construction must be carried out from top to bottom by the building, and the coating is bound by natural dividing seams, junctions of internal corners and external corners or downpipes and the like each time.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
