To repair the roof. The first case in which the leaking so we had to try and find where the leak is not that really where it's due. If the leakage is caused by the waving of the mortar. To repair the roof. May be done as follows.
The best way to repair a roof is to be demolished, new plaster, new ways to do this is the real solution. When leakage up. To repair the roof with cement or sand it. If an overflow to the head such as cement tiles. Or cement is not good. Or not the drainage holes. Sometimes it may be due to water uptake. This is great for several reasons. After that, a new family. Then closed with PU glue. This is done by the manufacturer. And people do have the expertise to do so. It will work out better than Method 2.
2 fillings Repair cracks and paint sealants. This method does not need to be removed. First, it will be easier to use the water for about ¾ TOA cement. To repair cracks, defects. And polishing complete with finishing. Finally, skin covered with toa Roof seal sun block chemicals were applied to the entire master's roof. This allows the heat better and will reflect the heat. With the leak as well. The chemical is taken as a film coating provides flexibility really well (but be careful because these chemicals are being used).
3 ways that I recommend is to shoot the PU foam. The waterproofing PU Foam, Polyurethane Foam has been developed to solve the water problem, repair roof leaks and waterproofing works well with high-quality Polyurethane Foam is suitable for repairing leaks. This foam can stop a shot for sure. Material, the foam will expand when exposed to water is 2 parts: first and second fluid Polyurethane Foam: Foam accelerator. The nature of the foam will not shrink. And reacts with water to grow a little to prevent leakage. Flexible as well. Have good adhesion to wet and dry surfaces. Safe environment. This foam material reacts with water to control the timing of 3 minutes and 30 seconds Training waterproofing Polyurethane Foam PU Foam (Polyurethane Foam) is not toxic to the body. Can be used with potable water storage tanks. The swimming pool is safe. Without the need to keep water out how to get rid of the fog, water, cement dust and dirt and grease. Within the cracks. Penetrate the injection of water (Packer) oblique angle of 45 degrees with a hiatus in the middle of the penetration depth of the rift between drill holes and then install the game (Packer) based on them. Chemical Foam Polyurethane Foam injection pressure to a pressure greater than 17 bar into the cracks. Or where there is leakage of water through the nozzle. Foams will react with water and then Seth came out to see. Then inject a shot in the head by the installation completely. And may need to inject a boost to water leakage is completely stopped the growth of the Polyurethane Foam Polyurethane Foam trend is up about 3.15 MPa pressure should be carefully repaired.
Step 4: Use silicone to fill that this is the only way to solve. In preliminary only. Can not really solve the problem.
