This week, Mr. Anju provided the decoration owner with professional knowledge about the waterproofing of the home improvement. In particular, the owners who are going to decorate in the summer should pay attention to the fact that if the waterproofing and wall treatment are improper in the decoration process, water leakage, water accumulation and mildew on the wall will not only affect the life but also bring it to the home and neighbors. In the event of economic losses, the quality of construction directly affects the “flooding†problem after occupancy. How to "waterproof", let us listen to Mr. Anju's suggestion.
How is waterproofing done?
Waterproofing is one of the most important and complicated processes in the construction process. Although it is not necessary for the owner to do the construction by hand, understanding the correct and complete process is beneficial to supervising the construction process and making the waterproofing process better.
Before laying the waterproof material, the base layer to be laid must be cleaned, the loose concrete and mortar on the surface of the base layer should be cleaned, and the protruding hard blocks should be removed. The cement mortar is uniformly brushed with cement mortar, waterproof oil surface and appropriate amount of adhesive. The surface mortar is made of 1:3 cement mortar, mixed with 3%-5% waterproof powder (or agent), and mixed after construction. Floor drains, casings, sanitary ware roots, yin and yang angles, etc., which are prone to condensed water, should also be used as a waterproof additional layer. The joints between the bathroom, kitchen and other rooms should be waterproofed. The waterproof layer of the kitchen wall and other rooms should be treated with four walls, and 300mm above the ground. The waterproof wall of the bathroom wall should be made and the height should be no less than 1800mm.
Look carefully at the four processes
1. The base layer must be dense, firm, clean, and free of floating soil.
2, the cement mortar and the base layer are combined with a solid and empty drum, the surface is smooth, no cracks and pitting on the surface, the yin and yang angles are made into a circular arc shape; the weak parts that are prone to leakage are smooth and smooth, and the combination is strict and smooth.
3, the leveling slope must meet the design requirements, smooth water flow.
4. The thickness of the protective layer must meet the strength requirements. It is strictly forbidden to damage the waterproof layer during operation.
Balcony "three defenses" is more important
The construction of the balcony is actually not big. The most important thing is the three “waterproofâ€. Today, Mr. Anju talks with everyone about how to do the waterproofing of the balcony.
The first is the waterproofing of the balcony sliding door. In the south, the construction technology of balcony sliding doors is often the key to whether the home can survive the rainy season. First of all, we must pay attention to the quality of the door, the sealing is better, and the inside and outside of the waterproof frame should not be mistaken. If the balcony has no windows at all or the windows are not well waterproofed, then the second waterproof line is in turn.
The second is the waterproofing of the balcony floor. First make sure that the ground has a slope and the lower side is a drain. Then make sure that the balcony and living room or balcony and living room have a height difference of at least 2 to 3 cm. It is difficult to make such a height difference between the living room and the balcony, because the building itself may have a height difference of only about 1 cm. Mr. Anju suggests that you use a marble plate to decorate it, which is both practical and beautiful. Of course, the two sides of the slate and the bottom should be sure to do the work of blocking the leaks. Use cement to make up the leak.
The third is to keep the floor drains open. The floor of the balcony should ensure the smooth drainage system (especially when the balcony is planted, it should be cleaned regularly to prevent the floor drain from leaking) to prevent the water from penetrating into the room. If the garden is artificially illuminated, it should also be waterproofed, especially lamps and leak-proof switches, to avoid damage caused by leakage during rainy days.
Fiberglass Self-adhesive Joint Tape is made of C-glass or E-glass filament yarn to weave fiberglass mesh and then treated with high elastic pressure sensative glue. Characteristics are high tensile strength, good dimensional stability, stability to temperature, good elasticity, capillary action, and corrosion resistance.
Fiberglass self-adhesive mesh tape is widely used in joining plaster plates, mending drywall cracks and piecing together and making up different kinds of plates. It goes on faster, adheres better, and requires no pasting or stapling. It won't tear, shrink, stretch or bubble, while it hides joints, cracks and holes permanently.
