Joint Replacement Construction 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 jointing. It is a critical area that can easily lead to water leaks and cause cracking or lifting of the siding. Cracks or peeling are signs of deterioration!

2. Application of Masking Tape

Check the position for applying the tape and carefully attach it to avoid embedding into the surface.

3. Application of Primer

Apply primer thoroughly with a brush to ensure no areas are left unpainted.

4. Filling the Sealant

Next, we will apply the sealant. The sealant used this time is a urethane seal! Urethane sealants are highly adhesive and cost-effective sealants. However, they have drawbacks such as low weather resistance, vulnerability to UV rays, and a tendency to attract dust, so protection with paint is necessary when used outdoors. The durability is approximately 10 to 15 years, making it a cost-focused material!

5. Trowel Finishing

Using a trowel that matches the joint width, press firmly and finish smoothly.

6. Removing Masking Tape

Remove the masking tape promptly after finishing.

We were able to finish beautifully this time as well!

Exterior 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

After the high-pressure washing is complete, we assess the condition of the exterior walls and perform substrate adjustments such as crack repairs.

3. Protection of Surrounding Areas

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

4. Primer Application

After completing the high-pressure washing and substrate treatment, we apply the first coat of paint, which is the primer. This primer is essential for ensuring that the middle and top coats adhere properly to the surface. A well-applied primer greatly enhances durability and finish quality!

The primer we use is Epoxy Power Sealer. Epoxy Power Sealer is a “water-based single-component epoxy primer for roofs and exterior walls” that is compatible with a wide range of substrates.

・High penetration and adhesion

・Strong adhesion

This paint is well-suited for siding exterior walls.

5. Intermediate Coating (Heat-Reflective Paint)

Next is the middle coating. This is an important process to bring out the performance of the paint, achieve a beautiful finish, and eliminate uneven application!

6. Top Coating (Heat-Reflective Paint)

Next is the top coating. This is the finishing touch for the exterior wall painting. We will be mindful to ensure there are no uneven spots or missed areas, resulting in a beautiful finish! The paint used is Astec Paint’s Silicon REVO1000-IR. The manufacturer’s expected durability is about 13 to 16 years. Astec Paint’s heat-reflective paint holds the NO.1 share among heat-reflective paints! With high cost performance and excellent heat-reflective properties, this paint is very popular with our company!

7. Accessory Painting (Eaves, Soffit, Rain Gutter, Fascia, Shutter Box)

Eaves

Eaves are less exposed to sunlight and are less prone to deterioration; however, due to poor sunlight exposure, they tend to be more susceptible to moss and mold. Therefore, 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 attached parts will undergo surface preparation such as scraping, and for metal parts, we will apply an anti-rust primer followed by a middle coat and top coat with Yumelock. We will ensure that every detail is thoroughly painted!

Necessity of Exterior Wall Painting and Maintenance Schedule

◇ Necessity and Purpose of Exterior Wall Painting

The role of exterior wall painting is primarily to protect the exterior walls. Like the roof, the 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 house and maintain its appearance, 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 to check for signs of deterioration such as fading, peeling, and cracking about 3 to 5 years after the initial painting.

By regularly checking the condition of the exterior walls and performing maintenance as needed, you can protect your valuable home while maintaining its appearance.

This time, we used a paint that enhances the thermal insulation of the exterior walls, and I believe you will feel the effects during the summer!
The most important part of exterior wall siding is the joint sealing material.
If the joint sealing is damaged, 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, I recommend at least performing emergency repairs on the joint sealing maintenance.
