Problems solved by technology

The waterproofing of building envelope structures (including roofs and exterior walls, etc.) generally adopts waterproof structures facing the water. Due to temperature stress and material aging, the exposed waterproof layer is cracked or damaged, resulting in leakage of the building. Phenomenon
[0004] When the exposed waterproof layer is cracked or damaged, many of the cracks are very small and difficult to find quickly with the naked eye. Even if you search carefully, it is difficult to quickly find the leakage point of the waterproof layer
The traditional solution in the prior art is usually to renovate the entire waterproof layer, and the cost is relatively high

preparation example Construction

[0040] The present invention has no special limitation on the preparation method of the exposed waterproof layer. It is sufficient to install a waterproof layer on the surface of the outer wall or roof that needs to be waterproofed, and then apply a different-color top coat on the surface of the waterproof layer.

[0041] In an embodiment of the present invention, when the waterproof layer is an asphalt-based waterproof coiled material, the present invention preferably brushes a layer of interface agent on the surface of the asphalt-based waterproof coiled material, and then brushes a layer of interface agent on the surface of the interface agent. Color surface coating is enough.

[0042] The present invention also provides a method for repairing cracks in the exposed waterproof coating described in the above technical solution, including:

[0043] On the surface of the exposed waterproof coating crack, repaint the different color top coat.

[0044] By adopting the method pro...

Embodiment 1

[0049] The present invention sets the exposed waterproof coating provided by the present invention on the roof of a certain villa in Haikou, specifically:

[0050] Brush and scrape a layer of blue waterproof paint on the roof of the villa, with a thickness of about 2 mm. Such as Figure 4 as shown, Figure 5 For the present invention is the picture of brushing blue waterproof paint in embodiment 1;

[0051] After finishing the brushing and scraping of the blue waterproof coating, the present invention brushes and coats the white architectural reflective heat insulation coating on the surface of the blue waterproof coating, with a thickness of about 0.06mm. Such as Figure 4 as shown, Figure 4 It is a picture of white architectural reflective heat-insulating coating applied in Example 1 of the present invention.

[0052] See results Figure 5 , Figure 5 It is the picture after the roof waterproofing construction of the villa in Example 1 of the present invention is com...

Embodiment 2

[0055] The present invention uses white flexible water-resistant putty with a thickness of about 1mm in the waterproof construction method of the outer wall of a self-built house in Danzhou, Hainan. After the white flexible water-resistant putty is applied and scraped, the surface of the white water-resistant putty is brushed with yellow acrylic water-based exterior wall paint with a thickness of about 0.06mm.

[0056] One year after the project was completed and put into use, slight cracks appeared on the window frame of the exterior wall, which was very eye-catching. After the owner found out, he used the same yellow exterior wall paint for local repairs in time, and there was no leakage on the wall.

Abstract

The invention provides a method for rapidly discovering cracks or breakage of an exposed waterproof layer, so that the portion with the cracks is repaired and maintained easily. According to the method, a heterochrome face coating is arranged outside the exposed waterproof layer, vision disparities in one or more aspects of color hue, color value and color purity exist between the heterochrome face coating and the waterproof layer, the heterochrome face coating and the waterproof layer can be distinguished with naked eyes, and the thickness of the heterochrome face coating is smaller than or equal to 0.6 mm. When the cracks exist on the exposed waterproof layer, the tension of the cracks on the waterproof layer can no be borne by the heterochrome face coating with the small thickness, then the heterochrome face coating cracks accordingly; due to the vision disparities, in the aspects of color and / or color value, between the heterochrome face coating and the waterproof layer, the portions where the cracks occur can be found simply with the naked eyes, the waterproof layer can be repaired and maintained easily, and maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, decoration and maintenance, in particular to a method for discovering cracks in an exposed waterproof layer and a method for repairing cracks in the exposed waterproof layer. Background technique [0002] Building leakage is a chronic disease that is difficult to cure in construction projects. According to the statistics of China Construction Waterproof Association, 65% of the newly-built houses in China will have different degrees of water leakage within one to two years after they are put into use. 75% of quality complaints, building water leakage problems intensified. Building waterproof engineering is not only related to the use of users, but also related to the foundation and life of buildings. [0003] According to the position of the waterproof layer in the building envelope structure system, it can be divided into two types: exposed waterproof structure and concealed water...
