Inquiry Details
We received an inquiry from a customer living in Asahi Ward, stating, “I am considering exterior wall painting and roof work for my house, which is nearly 20 years old. I am looking for a contractor who can provide convincing proposals from a professional perspective!”

Joint Replacement Construction Procedure

1. High-Pressure Washing (Bio Cleaning)

First, we thoroughly remove dirt and moss with high-pressure washing of the exterior walls! If dirt remains, it can affect the adhesion and durability of the paint, so we wash carefully.

This time, we used bio-cleaning! The bubbles you see are from the detergent. We also provided complimentary cleaning for the ground, foundation, and exterior structures!

2. Removal of Existing Sealant

We remove the existing sealant using a cutter and other tools. This is referred to as sealing, caulking, or jointing. It is a crucial area that can easily lead to leaks and can cause cracking or lifting of the siding. Cracks and peeling are signs of deterioration!

3. Preparation

Next, we will perform surface protection using masking tape and other materials. This is done to prevent dirt on the exterior walls and to achieve a clean finish.

We carefully check the position where the tape will be applied and stick it on without letting it dig into the surface.

4. Application of Primer

To enhance the adhesion of the sealing material to the surface, we apply primer with a brush, ensuring there are no missed spots.

5. Filling with Sealing Material

Next, we will inject the sealing material. Place the nozzle of the caulking gun at the bottom of the joint and fill it sufficiently.

The sealing material used for this project is Sunrise/SR Seal H100. The expected durability is 30 years,
with ultra-high durability, ultra-low pollution, flexibility, and resistance to dirt.

6. Finishing with a Trowel

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

7. Removal of Masking Tape

After the

finishing, promptly remove the masking tape, and the joint replacement work will be completed.

Exterior Painting Work Procedure

1. Substrate Adjustment

After the

high-pressure washing is completed, we will perform substrate adjustments such as crack repairs while checking the condition of the exterior wall!

2. Opening and Floor Protection

Next, we will 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 work!

Neglecting protection can create gaps, allowing paint to seep in or resulting in uneven lines. [/chat]

3. Primer Application


After completing high-pressure washing and surface preparation, the first step in applying the paint is to use a primer that ensures the middle and top coats adhere well to the surface. Applying the primer thoroughly makes a significant difference in durability and finish!

The paint used is Astec Paint / Epithic Filler AEII. [/chat]

4. Middle Coat

Next is the middle coat. This is a crucial step to unleash the paint’s performance, achieve a beautiful finish, and eliminate uneven application!

The paint used is Astec Paint / Silicon REVO1000-IR. The manufacturer’s expected durability is about 13 to 16 years. [/chat]

5. Top Coat


Next is the top coat. This will be the finishing touch for the exterior wall painting. We will ensure that there are no uneven areas or missed spots, aiming for a beautiful finish!

The paint used is the same as the middle coat, Astec Paint / Silicon REVO1000-IR.

6. Painting of Auxiliary Parts (Fascia, Soffit, Eaves, Rain Gutter, Shutter Box, Slim Duct, Balcony Waterproofing)

Fascia

Soffit

Rain Gutter

Shutter Box

Slim Duct

Balcony Waterproofing

After completing the surface preparation such as scraping for the

auxiliary parts, for iron components, we apply a rust preventive primer, followed by a mid-coat and top-coat using Rock Paint / Hyper Yumelock. We ensure that every detail is thoroughly painted!

For the eaves, we used Nippon Paint / Water-based Ken Ace, and for the balcony waterproofing, we used Kanae Chemical Industry / Kanae Water-based FRP Top (Top coat for FRP waterproofing).

Additionally, we disassemble the slim duct to paint it without sticking. By detaching and painting, we can also thoroughly paint the exterior wall beneath the slim duct!

Let’s make use of color simulation!

Our company has introduced a simulation software that allows you to freely change color combinations using images of your building taken during the shoot!

By utilizing this software, you can preview realistic images of not only the exterior walls but also the shutters and rain gutters after construction.

For this customer, we were able to use this simulation software to transform the originally single-colored exterior wall into a beautiful two-tone appearance with accents!

As you can see in the images below, the difference between the simulation image and the actual photos of the building after painting is so subtle that it is hard to tell apart; the finish is very close and beautiful!
