In home decoration, the selection of materials is crucial. Not only should the quality of the materials be considered, but their waterproofing properties are equally important. Especially in areas like the bathroom, where water exposure is frequent, proper waterproofing is essential to prevent damage and maintain a comfortable living environment. Here’s a detailed guide on how to properly handle waterproofing during home renovation.
When renovating spaces such as kitchens and bathrooms, it's advisable to use mortar-based waterproofing agents, such as Lao Yaer Waterproofing Agent. Many people have reported good results with this product. Unlike traditional waterproofing materials that require the base surface to be dry (with moisture content below 9%), these modern agents can be applied directly to wet surfaces. This not only simplifies the process but also ensures better adhesion and long-term effectiveness, especially in high-moisture environments like bathrooms.
Why is waterproofing necessary?
During the renovation of new homes, the original waterproofing systems installed by developers are often disturbed or removed. To protect your property and avoid disputes with neighbors, it's essential to reapply waterproofing. Water can easily spread through small leaks, causing damage to lower floors and leading to costly repairs or legal issues. Additionally, re-waterproofing can provide up to 3–5 times more protection than before the renovation.
What areas need waterproofing?
Key areas that require waterproofing include the floors and walls of bathrooms and kitchens, balconies, all ground-level floors and walls, and basements. Roofs—whether prefabricated or cast-in-place—should also follow national standards for waterproofing.
Basic requirements for the base surface:
The surface must be clean, free of debris, and have a moisture content no higher than 9%. It should be level and compact, with all corners and joints properly prepared.
First layer of waterproofing:
1. Apply a flexible waterproof layer using either coatings or membranes. The base must be dry, making it suitable for construction after several days of hot and dry weather. After application, a water retention test should be conducted.
2. For coating waterproofing, a common method is "one cloth and two coats." Clean the base, apply the first coat, let it dry, then lay a layer of glass fiber mesh for reinforcement. Cover with another coat and ensure the total thickness exceeds 3 mm.
3. If using membrane materials, apply adhesive on both the back of the membrane and the base surface, then carefully lay it from far to near, ensuring proper alignment and seam treatment.
4. The second layer is a rigid waterproof layer, typically made from high-grade fatty acid mortar waterproofing agents, cement, sand, fine aggregate, and fibers. It should be about 20–30 mm thick.
Steps for applying the rigid waterproof layer:
- Install grids according to specifications, spacing them at 4000mm x 4000mm.
- Moisten the base surface without leaving standing water.
- Apply the mortar or fine stone concrete starting from the farthest point, working towards the nearest, and complete each section in one go, ensuring proper compaction and smoothing.
- After initial setting, remove the dividing strips, roll and adjust the joints.
- Seal the joints with flexible sealing material and perform regular watering and maintenance.
- If there is a rooftop garden, cover the soil promptly to prevent erosion.
Proper waterproofing is a critical step in any home renovation project, ensuring durability, safety, and peace of mind for years to come.
