Joint Replacement Construction Steps
1. Removal of Existing Sealing Material
This is referred to as sealing, caulking, or jointing. It is a critical area 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 Sealant
SR Seal H100 has a lifespan of about 3 times that of regular caulking materials (urethane, modified silicone, etc.). The expected lifespan is approximately30 years.
5. Finishing with a Trowel
6. Removal of Masking Tape
We were able to finish beautifully this time as well!
Exterior Wall Painting Construction Procedure
1. High-Pressure Washing


First, we thoroughly remove dirt and moss from the exterior walls using high-pressure washing! If dirt remains, it can affect the adhesion and durability of the paint, so we wash carefully.
We also provided a complimentary cleaning of the floor and inside the rain gutters!
2. Substrate Adjustment
3. Protection of Areas
4. Primer Coat
After completing high-pressure washing and substrate treatment, we apply the first coat of paint, which is essential for ensuring that the middle and top coats adhere well to the surface. A thorough application of the primer significantly impacts durability and finish quality!
The primer we use is the White Filler from Astec Paint. Astec Paint’s “White Filler” becomes a soft film (micro-elastic) after drying, allowing it to follow the movement of the building and hairline cracks. It also has substrate adjustment capabilities and is a water-based, single-component flexible acrylic primer suitable for a wide range of substrates.
5. Middle Coat (Heat-Reflective Paint)
6. Top Coating (Heat-Reflective Paint)

7. Accessory Part Painting (Eaves, Soffit, Rain Gutter, Fascia, Shutter Box)
Soffit
The eaves are less exposed to sunlight and therefore tend to be less prone to deterioration; however, due to poor sunlight exposure, they are more likely to develop moss and mold. For this reason, we use paint with high anti-mold and moisture-permeable properties for the eaves.
The paint used is Nippon Paint / Ken Ace G2.
Fascia
Rain Gutter
Shutter Box
The Necessity of Exterior Wall Painting and Maintenance Schedule
◇ The Necessity and Purpose of Exterior Wall Painting
The role of exterior wall painting is primarily to protect the walls. Like the roof, the exterior walls are directly affected by rain, wind, and UV rays. Regular exterior wall painting helps prevent these damages and plays a role in extending the lifespan of the house.
Additionally, making the house look beautiful is also a role of exterior wall painting. Since the exterior walls determine the first impression of the house, maintaining their beauty enhances the comfort of the residents and the evaluation from the surroundings.
If you want to extend the lifespan of your house and maintain its aesthetics, exterior wall painting is necessary.
◇ Maintenance Schedule for Exterior Wall Painting
Generally, the lifespan of exterior wall painting is said to be about 7 to 10 years. However, like the roof, it varies depending on the type of paint used, the painting method, and climatic conditions. Inspections are necessary 3 to 5 years after the first painting to check for signs of deterioration such as fading, peeling, and cracks.
By regularly checking the condition of the exterior walls and performing maintenance as needed, it is possible to protect your valuable home while maintaining its aesthetics.

Summary
This is our track record of exterior wall painting and sealing work in Zushi City, Kanagawa Prefecture!
This time, we used paint that improves the heat insulation of the exterior walls, and you should be able to feel the effects during the summer!
The most important part of exterior wall siding is the joint sealing material.
If the joint sealing comes off, it can lead to leaks and internal wood decay, as well as warping and cracking of the siding material.
Even if exterior wall painting is difficult due to costs, we recommend at least maintaining the joint sealing as an emergency repair.
