Porcelain tile exterior wall how to do waterproofing leakage?

Porcelain tile decorative surface wall leakage is mainly due to improper construction of decorative tiles, decorative tiles themselves are sintered ceramic material, so impermeable, and the bonding material is cement paste, easy to cause decorative tiles on all sides of the mortar is not full and the formation of cavities. And because of the cement between the tile and tile hook appears very fine horizontal cracks and some honeycomb, pockmarked and dog holes, rain is very easy to penetrate from these seams, holes, holes into the leveling layer and tile lining, and be adsorbed in it, because the finish tile impermeable, water is trapped inside and form a small reservoir, can only seepage indoors. After the rain, when the sun shines directly on the outside wall surface, due to the high temperature outside, the temperature inside is low, at this time stored in the leveling layer, tile lining water vapor through the leveling layer of capillary holes into the inner wall, resulting in the inner wall wet and moldy interior decoration, the outer wall from the inside outflow of white minerals, affecting the wall aesthetics.

The treatment method is divided into the following steps:

1, first of all, the outer wall cleaned up, so that the surface is free of grease, holes and holes in the joints do not leave loose particles such as dust and cement and all debris.

2, with waterproof powder and JS composite waterproof coating at 3.5:1 ratio of mixing made of repair paste, will be between the bricks on all cracks, holes inlay dense.

3, to be dry, with silicone water-repellent agent will be sprayed all over the wall. Silicone water-repellent agent is an environmentally friendly products, do not change the original color of the substrate, not easy to stick with the dust, does not affect the decorative effect of decorative tiles.

Through the above method of treatment of the wall, due to a large number of capillary pores and fine cracks are closed by the hydrophobic agent, while the hydrophobic agent in the external wall surface formed by the hydrophobic coating layer, so that the rain like falling on the lotus leaves as difficult to stay in the external wall surface, which eliminates the source of water seepage, so as to achieve waterproofing purposes.
