Kitchen, Balcony, Bathroom Construction Process
Step 1: Prepare Tools
Ensure all necessary tools and waterproofing materials are prepared before the application, including brushes, trowels, rollers, mixers, etc.
Step 2: Waterproofing Procedures and Construction Requirements
1. The surface must be flat, clean, free of sanding and loose particles. It is necessary to first clean the base for waterproofing. This requires the use of tools such as brushes, spatulas, shovels, and hammers for cleaning.
2. All protruding granules and floating dust debris must be thoroughly cleaned. Additionally, if the base is uneven, the application of waterproofing materials during construction may result in uneven thickness, leading to poor waterproofing effects, cracking of the waterproof layer, and leakage issues.
3. For uneven substructures on floors and walls, use Leak Sealer to level the surface. In the bathroom, an inclination must also be created on the base surface to facilitate water flow, with varying heights.
Step 3: Applying Waterproof Coating
Once the groundwork is taken care of, it's time to start mixing the waterproof paint, which can be used after thorough mixing according to its instructions.
Waterproof coatings require two coats. First, apply horizontally, then after drying, proceed with vertical brushing. Especially for polymer-based waterproof membranes, a thickness of over 1.5 millimeters is necessary to achieve better waterproofing effects.
2. During application, focus on sealing areas prone to leaks such as floor drains, pipe roots, corners, and阴阳 angles first. For other areas, paint the vertical surfaces before the flat surfaces. The shower wall should be coated up to 180 centimeters, and the bathtub area should be painted up to 30 centimeters above the bathtub.
3. When applying wall roller coating, avoid creating a smooth finish as it may lead to tile hollowing and falling off later on. Try to apply the waterproof coating in one go to the wall. If you opt for a textured finish, it would be even better!
The entire waterproof coating must be fully applied without any omissions, securely bonded, and free from cracks, bubbles, or peeling.
Step 4: Waterproofing and Water Tightness Test
Once the waterproof coating is completely dry, you can initiate a 72-hour water-tightness test to verify the effectiveness of the waterproofing. During the test, the water level should be elevated 3-4 centimeters above the floor, and a waterstop should be installed at the doorway.
Ensure the balcony's water test extends to the sliding door. If there's leakage through the drain to the room, you can saw the drainage pipe about 1-2 cm lower than the sliding door to prevent water from spilling into the room.
After 72 hours with no significant changes, it indicates there are no leaks, and the water can be drained. If leakage occurs, the waterproofing needs to be redone. This situation typically arises at the junction of pipe walls and corners. Sometimes, the location of pre-buried pipes also requires close attention, as leaks often occur due to negligence in these areas.
Step 5: Apply Protective Layer
After ensuring no leakage, apply a protective layer using cement mixed with 801 adhesive by rolling on the surface of the waterproof coating to prevent damage to the waterproofing layer during later construction. The protective layer must fully cover the waterproofing layer. Brush it up the wall by 10 centimeters.
