Joint Sealing Replacement Construction Steps
First, we will replace the joint sealing!
Depending on the paint, the work process may be reversed.
The sealing material used this time is Sunrise Co., Ltd. / SR Seal H100.
Its features include ultra-high durability, ultra-low pollution, flexibility, and resistance to dirt.
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 can cause cracking or lifting of the siding (exterior wall). Signs of deterioration include cracks and peeling!
2. Applying Masking Tape
This is an important task to ensure a clean finish.
3. Application of Primer
4. Filling of Sealant Material
SR Seal H100 has a durability of about 3 times that of regular caulking materials (urethane, modified silicone, etc.). The expected durability is approximately 30 years.
The cost is about 50,000 to 100,000 yen higher compared to regular modified silicone for a building with a total floor area of 30 tsubo.
5. Finishing with a Trowel
6. Removal of Masking Tape
Exterior Wall Painting Construction Procedure
1. High-Pressure Washing
2. Protection of Various Areas
3. Primer Application
4. Middle Coating
5. Top Coating
The paint used this time is Seika Japan Co., Ltd. / Dia Super Seranflex!
Dia Super Seranflex is an ultra-high durability inorganic paint that offers excellent cost performance in relation to its durability and benefits.
6. Painting of Auxiliary Parts
Auxiliary parts refer to areas other than the exterior walls and roof!
The painting methods and the paints used can vary depending on the location, so caution is necessary!

Balcony Top Coat Construction Procedure
1. Surface Preparation and Roughening
By doing this, we increase the area where the paint can adhere, thereby enhancing adhesion.
We will move or elevate any obstacles, such as outdoor units, that may hinder waterproofing work.
2. Primer Application (First Coat)
3. Top Coat Application (Two Coats)
After painting, we will check for any missed spots.
4. Completion of Balcony Top Coat Work
This time, we introduced the highly popular Diamond Super Seranflex from our company!
The process for balcony top coating varies depending on the materials used, so knowledge is essential!
Benefits of Simultaneously Performing Exterior Painting and Sealing
As in this case, there are several benefits to performing exterior painting and sealing at the same time.
This is important for the protection and maintenance of your home, as well as cost performance, so please keep this in mind!
Improved Waterproofing
Sealing prevents water intrusion by sealing gaps and cracks in the exterior walls. By performing sealing simultaneously with exterior painting, we enhance the waterproofing of the entire painted surface, preventing damage from rainwater and other sources.
Long-Term Durability
The new paint layer and sealing enhance the weather resistance of the exterior walls, protecting them from UV rays and climate changes. This helps delay paint peeling, fading, and the deterioration of the sealing.
Maintenance of Aesthetics
Sealing fills small cracks and holes in the exterior walls, smoothing the surface before painting and providing a beautiful finish. By performing painting and sealing simultaneously, we achieve a consistent appearance and texture.
Improved Cost Efficiency
By performing exterior painting and sealing at the same time, we can save on construction costs such as scaffolding setup compared to doing them separately.
This leads to a reduction in the overall cost of the project.
Structural Protection
Sealing also plays an important role in protecting the structural components of the building. By thoroughly filling gaps in the exterior walls, we can prevent moisture and pest intrusion, extending the lifespan of the building.
Improved Energy Efficiency
By sealing gaps, we reduce air leakage during heating and cooling, improving energy efficiency.
This also leads to savings on heating and cooling costs, making it an environmentally friendly choice.
Simultaneously performing exterior painting and sealing not only enhances aesthetics but also offers many functional advantages, making it one of the best methods for protecting and maintaining a building.
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 ultraviolet 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 home and maintain its appearance, we recommend exterior wall painting!
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, this can vary depending on the type of paint used, the painting method, and climatic conditions. Inspections are necessary 3 to 5 years after the initial painting to check for signs of deterioration such as fading, peeling, and cracking.
By regularly checking the condition of the exterior walls and performing maintenance as needed, you can protect your valuable home while maintaining its appearance.
Description of the Paint Used [Seika Japan Co., Ltd. / Super Ceramflex]
Super Weather Resistance
Super Ceramflex has weather resistance that exceeds that of fluororesin paints. This allows for the long-term maintenance and protection of the building’s aesthetics.
Super Low Pollution
This paint has super low pollution properties, making it difficult for contaminants to adhere, and dirt can be easily washed away by rainwater. This helps maintain the beauty of the painted surface for a longer time.
Flexibility
Due to its high flexibility, the risk of cracking is significantly reduced even when applied over sealing. This is because it easily follows the movement of the substrate.
Moisture Permeability
Moisture permeability refers to the property of allowing moisture in vapor form to escape before it condenses into droplets.
Super Ceramflex has high moisture permeability, allowing water vapor to pass through while preventing water droplets from passing. This efficiently releases moisture from inside the walls, preventing issues such as thermal swelling.
Environmental Consideration
By combining inorganic paints with organic components, it achieves both environmental consideration and high performance. In particular, water-based and low-solvent types are offered as environmentally friendly options.
Improved Workability
To accommodate various substrates, it is possible to add new functions through combinations with adjusting materials. This expands the flexibility and application range of the construction.
With these features, Super Ceramflex is highly suitable for exterior wall painting, enabling long-term protection and maintenance of aesthetics.
