One, Waterproof Coating Cleaning Method
1、Remove
Generally, it is best to remove the dry portion of the waterproof coating with a scraper, as it is difficult to clean and can be removed more effectively with a scraper. If it is very difficult to remove with a scraper, you can add some water to facilitate removal.
2、Cooling Oil
You can apply a degreasing agent to the areas where waterproof coating has been applied. The degreasing agent contains substances that can dissolve the waterproof coating. After the chemical reaction, simply rinse the area clean.
3、 Rinse with water
If the waterproofing material is water-based, it can be directly rinsed off with water. However, it is essential to clean it up immediately, as it becomes difficult to remove once it has dried.
4、Cleaning with detergent
If the fabric is stained with waterproof coating, you can rub lard onto the fabric, then soak it in a detergent solution, rinse with water, and finally, bleach it to remove the stain.
Two. important considerations for waterproofing coating application
1、The waterproof substrate must be solid, dry, and smooth, with no debris. Any unevenness or cracks must be filled with cement mortar.
2. Pre-treat the substrate with a thin layer (0.2-0.3mm thick) of diluted paint (using 200# gasoline or xylene) after proper dilution.
3. Typically, apply three coats, allowing the first coat to fully dry (usually 24 hours) before applying the second. Apply each coat in a vertical direction.
4、The proportions should be followed according to the packaging requirements. During application, mix components A and B in a clean container by hand or with an electric mixer for 3-5 minutes until thoroughly combined. Apply the mixture evenly to the substrate using a plastic or rubber scraper.
