First, the basic concept articles
1. Why should home improvement be waterproof?
When renovating a new house, hydropower transformation is inevitable, which often damages the original waterproof layer. To strengthen the waterproofing and protect property, avoid disputes with neighbors, and ensure long-term safety, waterproofing during renovation is essential.
2. How to calculate the cost of home improvement waterproofing?
Waterproofing is a crucial part of home renovation, but it's relatively inexpensive. Using high-quality materials and skilled labor, the cost is about 60-100 yuan per square meter, which accounts for only about 1% of the total renovation cost. Despite being a small expense, it's a vital investment in long-term protection.
3. What are the risks of not doing waterproofing?
Water can seep through even the smallest cracks. In bathrooms and kitchens, where water is frequently used, leaks can cause damage to lower floors, leading to costly repairs and potential legal issues. Re-waterproofing after the fact can cost 3-5 times more than proper initial waterproofing.
4. What are the main areas that need waterproofing?
The toilet, kitchen, balcony, first-floor rooms, basement ground floor, and all walls require waterproofing. These areas are most vulnerable to moisture and water damage, so they must be properly treated.
5. Why is the waterproof height in toilets set at 1.8 meters?
This height ensures comprehensive protection, especially around showers or faucets. If the waterproof layer is too low, water can seep into the walls, causing mold, peeling tiles, and loss of waterproof effectiveness. It’s recommended to apply this height uniformly, even if some areas could technically be lower.
6. Why is the balcony waterproofed?
Exposed balconies must be waterproofed to prevent rain and snow from seeping down. Even non-exposed balconies may be used for washing, making waterproofing necessary to prevent water damage.
7. Why is the kitchen also waterproofed?
The kitchen is the second most critical area for waterproofing, as water from utensils can leak through floor drains. The floor and walls should be waterproofed up to 0.3 meters, and higher on walls near sinks for extra protection.
8. How to calculate the waterproof area in home decoration?
Toilet waterproof area = [(perimeter of the room - door width) × 1.8m (height) + floor area]. Kitchen waterproof area = [(perimeter of the kitchen - door width) × 0.3m (height) + floor area]. This helps estimate the required material quantity accurately.
9. When should waterproofing be done during the renovation process?
Waterproofing should be done immediately after hydropower renovation. It’s important to apply it directly on the structural base to ensure optimal results and prevent future leaks.
10. How long does the waterproofing process take?
For materials like acrylic or JS, it typically takes about three days. Base preparation takes 1-2 hours, followed by three layers of coating applied every 4-8 hours. After drying, a closed water test can be conducted the next day to check for leaks.
Second, material cognition
1. What types of waterproof materials are available in the market?
There are over a hundred waterproofing products, but only a few are commonly used. Popular options include polyurethane, acrylic, polymer cement, and cement mortar. Each has different properties and applications.

10. Why isn't a continuous waterproof layer used in kitchens and bathrooms?
Kitchens and bathrooms have complex structures, making it difficult to apply continuous layers. Coatings are preferred because they can be applied evenly and effectively cover all areas.
11. What is the role of "plugging treasure" in waterproofing?
Plugging treasure is a rigid waterproof material used for sealing cracks and joints. It is not suitable for long-term waterproofing due to its lack of flexibility and tendency to crack under stress.
12. Can plugging treasure replace cement for tiling?
Yes, it can be used as an alternative to cement for tiling, but the surface must be clean and moist before application.
13. Can plugging products be granulated and still work?
If stored improperly, plugging products can become granular and lose effectiveness. It's best to avoid using such products to ensure proper waterproofing performance.
Third, material selection articles
