| Process Leading to the Construction |
| We received an inquiry from a customer living in Kawasaki-ku, Kawasaki, stating, “The joints have deteriorated, and the underlying metal (joiner) is visible, so I would like to get estimates for joint replacement and exterior wall painting through a comparative estimate.”
Since the customer expressed a preference for “durable joints,” we proposed the high-durability sealing material, Auton Exceed! |

500,000 to 1,000,000 yen |

Exterior Wall Painting Construction Procedure
1. High-Pressure Washing

We thoroughly remove dirt and moss from the exterior walls with high-pressure washing! If any dirt remains, it can affect the adhesion and lifespan of the paint, so we wash carefully.
2. Protection of Areas

3. Primer Application

4. Top Coat
Royal Sera Clear is a clear paint compatible with photocatalytic siding (difficult-to-adhere siding).


5. Painting of Additional Parts (Rain Gutter, Soffit, Shutter Box)
Rain Gutter
Soffit
・Shutter Box

Joint Replacement Work Procedure
1. Removal of Existing Sealing Material
It is referred to as sealing, caulking, or joints. This area is crucial as it can easily lead to water leaks and cause cracking or lifting of the siding. Cracks and peeling are signs of deterioration!
2. Applying Masking Tape
3. Application of Primer
4. Filling with Sealing Material
Auton Exceed has a lifespan of about 3 times that of regular caulking materials (such as urethane and modified silicone). 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. Finishing with a Scraper
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/Royal Ceraclear, it is not allowed to apply it to the replaced joints, 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 common to carry out joint replacement and exterior wall painting together, so caution is necessary!

We were able to finish beautifully this time as well!

Summary
Above are the construction results for exterior painting and joint replacement in Kawasaki City, Kawasaki Ward!
Siding is strong against water from the surface, but weak against water from the back and sides.
When joints break, water can reach the sides and back of the siding, causing cracks and warping.
This can also lead to corrosion of the underlying structure, so maintenance before the joints break is recommended!
Estimates and inspections are, of course, free! If you have any concerns regarding roofs, rain gutters, exteriors, or exterior structures, please consult Kakeru Koumuten Co., Ltd. in Aoba-ku, Yokohama!
