Publish Time: 2024-11-26
Building and stone waterproof emulsion may be damaged due to natural aging, wear, chemical corrosion or mechanical damage during long-term use. Effective repair measures can not only extend its service life, but also ensure the durability of the waterproof effect.1. Preliminary assessment and cleaningDamage assessment: First, conduct a detailed inspection of the damaged area to assess the extent and scope of the damage. If it is a small area of local wear, local repair can be carried out; if it is a large area or deep damage, the entire area may need to be re-coated.Surface cleaning: Use appropriate tools (such as high-pressure water guns, brushes, scrapers, etc.) to remove loose materials, dust, oil stains and old waterproof layers from the damaged area. Make sure the surface is clean, dry and free of impurities.2. Local repairFill cracks and holes: Use waterproof mortar or special filling materials to fill cracks and holes. When filling, ensure that the material fully fills the gap and is flush with the surrounding surface after curing.Grinding and polishing: If there is a color difference or unevenness between the filled area and the surrounding surface, you can use a grinding tool to grind it, and then polish it to make the repaired area consistent with the surrounding surface.3. Re-apply waterproof emulsionPrimer treatment: Before re-applying waterproof emulsion on the repaired area, perform primer treatment first. Primer can enhance the adhesion between the waterproof emulsion and the substrate and improve the waterproof effect.Waterproof emulsion coating: Choose a product that is the same or compatible with the original waterproof emulsion to ensure uniform coating and moderate thickness. Avoid bubbles and gaps during coating.Layered coating: If you need to enhance the waterproof effect, you can apply multiple layers of coating, and each layer should be fully dried.4. Strengthen protective measuresAdd a protective layer: Building and stone waterproof emulsion After the waterproof emulsion is applied, a protective layer (such as waterproof coating, protective film, etc.) can be added to enhance the wear resistance and anti-aging ability of the waterproof layer.Regular maintenance: After the repair is completed, establish a regular maintenance plan, regularly check the condition of the waterproof layer, and promptly detect and deal with new damage.5. Special case handlingChemical corrosion repair: building and stone waterproof emulsion For damage caused by chemical corrosion, it is necessary to neutralize and remove the corrosive substances first, and then perform local repairs and re-apply waterproof emulsion.Mechanical damage repair: For mechanical damage (such as impact, scratches, etc.), it is necessary to perform local repairs first, and then re-apply waterproof emulsion.6. Professional construction and quality controlProfessional construction: building and stone waterproof emulsion If the damage is more serious or involves a large area, it is recommended to hire a professional construction team for repair. Professional construction teams have rich experience and professional tools to ensure the quality of repair.Quality control: During the repair process, strict quality control is carried out to ensure that each step meets standards and specifications. After the repair is completed, a comprehensive inspection and test is carried out to ensure that the waterproof effect is as expected.When the building and stone waterproof emulsion is worn or damaged, it can be effectively repaired through preliminary evaluation and cleaning, local repair, re-applying waterproof emulsion, strengthening protective measures, special case handling and professional construction and quality control. These measures not only restore the integrity and performance of the waterproof layer, but also extend its service life, ensuring the long-term waterproofing of the building and stone.
