Joint Replacement Work Procedure
1. Removal of Existing Sealing Material

This is commonly referred to as sealing, caulking, or jointing. It is a critical area that can easily lead to water leaks and cause cracking or lifting of the siding. Cracks and peeling are signs of deterioration!
2. Preparation (Masking Tape Application)
3. Application of Primer
4. Filling with Sealing Material
Auton Exceed has a lifespan of about 3 times that of regular caulking materials (urethane, modified silicone, etc.). The expected lifespan is about 30 years. The cost will be about 50,000 to 100,000 yen higher for a building with a total floor area of 30 tsubo.
5. Spatula Finish

6. Removal of Masking Tape
That concludes the process.
Normally, exterior wall painting is done after replacing the joints, but in the case of Kikusui Chemical/SP Power Fluorine Clear, it is not allowed to apply it to the joints after replacement, so the joint replacement was done after painting. The process may vary depending on the materials used, and knowledge is required!
If the exterior wall is siding, it is often the case that joint replacement and exterior wall painting are done together, so caution is necessary!
This time, we were able to finish beautifully without any issues!
