Background to the Construction
We received an inquiry from a customer living in Atsugi City, stating, “Since the house is older, I would like to request an inspection of the roof and exterior walls.”

This time, the customer expressed a desire to proceed with painting the roof and exterior walls, so we prepared several estimates for them.
After comparing with estimates from other companies, they entrusted us with the roof and exterior wall painting work!
They praised us, saying, “I feel reassured knowing that you can handle everything from scaffolding to the entire project in-house!”
The plan they entrusted us with includes roof painting using Fine Perfect Best and exterior wall painting using Royal Sera Clear, which enhances the existing siding pattern!

For the sealing material, they entrusted us with the high-durability sealing material, Auton Exceed!

Roof Painting Construction Procedure

1. Cleaning and Surface Preparation

First, we thoroughly remove moss and dirt from the roof using high-pressure washing and scraping. We will also repair any cracks in the roof.

2. Protection of Various Parts

Next, similar to exterior wall painting, we will protect areas that will not be painted, such as rain gutters, using masking tape and polymer sheeting.
This is an important task.

3. Primer Application

Next, by applying the primer thoroughly, we can achieve differences in durability and finish.

4. Spacer Installation

Next, after the primer, we insert spacers between the roofing materials to ensure a pathway for rainwater and moisture to escape.

5. Intermediate Coating

Next is the intermediate coating. We used Fine Perfect Best in black for the paint.
The durability is said to be about 10 to 12 years. The durability may vary depending on environmental factors.

6. Top Coating

Next is the top coating. This will complete the roof painting.

7. Completion

Finally, we will clean up any debris that has fallen and finish the job!

Exterior Wall Painting Construction Procedure

1. High-Pressure Washing

We thoroughly remove dirt and moss with high-pressure washing of the exterior walls!

2. Protection of Areas

We will protect areas that will not be painted, such as windows, sashes, and floors, using masking tape, blue sheets, and poly masks. This is a very important task in the painting process! If protection is neglected, gaps may form, allowing paint to seep in or resulting in uneven lines.

3. First Coat Application

This is an important step to showcase the performance of the paint, achieve a beautiful finish, and eliminate uneven application! This time, we will be using a clear coating, so unlike regular exterior wall painting, we will only apply the finish coat twice, and there will be no undercoat process.

4. Second Coat Application

This is the finishing of the exterior wall painting. We focus on ensuring there are no uneven spots or missed areas, resulting in a beautiful finish! The paint used is from Kikusui Chemical / Royal Seraclear!

Royal Seraclear is a clear paint compatible with photocatalytic siding (difficult-to-attach siding).

5. Painting of Additional Parts (Rain Gutter, Eaves, Soffit, Vertical Gutter, Foundation Water Cut)

We will thoroughly paint every detail that can be painted! [/chat]

Joint Replacement Work Procedure

1. Removal of Existing Sealing Material

We will remove the existing sealing material using a cutter or similar tool.
This is referred to as sealing, caulking, or joints. It is a critical area that can easily lead to leaks and cause cracking or lifting of the siding. Cracks and peeling are signs of deterioration!

2. Preparation (Masking Tape Application)

Check the position of the tape and apply it carefully to avoid embedding into the surface.

3. Application of Primer

Apply the primer with a brush or similar tool, ensuring there are no missed spots.

4. Filling with Sealant

Place the nozzle of the caulking gun against the joint base and fill it adequately. The caulking material used is Auto Chemical/Auton Exceed.
Auton Exceed has a durability of about 3 times that of regular caulking materials (urethane, modified silicone, etc.). The expected durability is about 30 years. The cost will be approximately 50,000 to 100,000 yen higher for a building with a total floor area of 30 tsubo.

5. Finishing with a Trowel

Use a trowel that matches the joint width to press firmly and finish smoothly.

6. Removal of Masking Tape

Remove the masking tape promptly after finishing.

This concludes our discussion.
Normally, we would perform the joint replacement after the exterior wall painting, but in the case of Kikusui Chemical/SP Power Fluor Clear, it is not allowed to apply it to the joints after replacement, so we replaced the joints after painting. The process varies 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!
This time, we were able to finish beautifully without any issues!
