Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproofing method for outer wall tiles constructed on a concrete building.

[0002]

2. Description of the Related Art Conventionally, a tiled outer wall is considered to be a semi-permanent outer wall material with excellent waterproof performance.
Providing waterproofness to the outer wall tiles has been left as a completely unconsidered matter.

However, porcelain, stoneware and porcelain tiles have efflorescence adhering to the surface layer of the tiles, which flows out from the periphery of the media shortly after the outer wall is completed, and impairs the appearance and design of the tiles as a white flower phenomenon. The outer wall tiles are repeatedly subjected to the effects of dryness and humidity, temperature changes, vibrations, etc., and the stresses associated with the movement occur, which causes stress peeling and cracks in the surrounding media and tiles, and through this, the adhesive mortar on the back surface passes. It is said that water permeates into the mortar and reacts with the free lime content of the mortar to elute efflorescence. But,
From the past recognition that these tiles and media are generally waterproof, the outer wall tiles at the time of new construction had no waterproof treatment.

Porcelain tiles, which are said to have no water absorbency, show a colored pattern by applying a glaze, but the surface has a structure very similar to that of glass, and the deterioration factor is that of polluted gas contained in the atmosphere. It is said that the acidic components of the chemical reaction with the reaction factors on the tile surface accelerate the deterioration.
In addition, it is said that the porcelain tiles have a matt finish, and these are surface changes due to dust, wind, and rain in the atmosphere.

The cement component CaCo ₃ used in the media mortar projects from the back surface to the tile surface under the influence of moisture, and the tile surface is contaminated with white. Most of these are calcium carbonate. Moreover, since the surface of the porcelain tile is also composed of a silicic acid component, precipitation from that portion is also one of the stains.

[0006]

As described above, the conventional finishing techniques for outer wall tiles cannot prevent deterioration and damage due to water permeation and retention permeation, and repeatedly cause outflow pollution of efflorescence. It will be. In addition, the deterioration of the performance of tile surface layer and media mortar that has deteriorated over time is accelerated by repeated movements, and the water that permeates from the tile and media promotes the outflow of efflorescence and deteriorates without water absorption. Even in porcelain tiles, exhaust gas from automobiles, which is one of the pollutants in the atmosphere, is sticky and sticks dust and dirt in the air to the tile surface. Other molds, algae, moss, etc. adhere to the surface and propagate and spread to areas with high surface humidity, and the media part progresses inward like a wedge, so leaving them unattended not only damages the building itself, but also the appearance. It must be said that some kind of waterproofing is indispensable because it is difficult to keep silent.

[0007]

SUMMARY OF THE INVENTION In light of the above need, the present invention seeks to provide a method of waterproofing exterior wall tiles and to provide new improvements to the finish treatment of exterior wall tiles.

Therefore, in the present invention, after finishing the outer wall tile composed of tiles and decorative media, the entire surface of the tiles and media is impregnated with a permeable waterproof material and a water-repellent material, and then a super weather resistant acrylic silicone resin system. A waterproof coating material such as fluorine resin is applied.

The tiles are the same in terms of the construction means of the present invention, although there are qualitative differences, such as ceramics having water absorption, stoneware, and porcelain having no water absorption. The waterproof material may be any of the above resin-based materials and other durable waterproof materials that do not impair the design of the tile.

[0010]

[Operation] Tile base mortar and pasting mortar undergo repeated expansion and contraction due to water absorption, and positive and negative repeated reactions occur similar to thermal expansion and contraction. It suppresses.

Further, the rainwater infiltrated from the cracks not only fills the floating gaps, but also penetrates into the tile surface layer and the capillaries and the capillaries of mortar and concrete, and becomes ice when it is cold, and its volume increases, and the expansion pressure of the When collapsed, water vapor pressure is generated in the capillaries during intense heat, which increases the stress and the repeated stress expands the floating, but it has the effect of preventing the occurrence of such an abnormal phenomenon. .

[0012]

As described above, according to the present invention, the entire surface of the tile and the image is impregnated with the penetrating waterproof material and the water repellent material, and then the durable waterproof material is applied to the outer wall tile of the conventional building or the outer wall tile. Water that has penetrated and stayed in the media can be eliminated, and the stain and penetration of the tile surface, aging stain due to accumulated moisture, and dry-wet action are suppressed, and cracks and expansion due to freezing damage of water-absorbing tiles especially in cold regions. Stripping can be prevented, construction is extremely simple, and the effect of forming and maintaining outer wall tiles as a sound finishing layer without losing the aesthetic appearance over a long period of time is remarkable.
