Inquiry and Proposal Details

〇 Inquiry Details
We received the following inquiry from a customer who purchased a used house in Ota-ku, Tokyo!
・I bought a used house, and I want to change the appearance by remodeling the retaining wall and exterior wall.
・The caulking at the seams of the siding has deteriorated, so I want to repair it to prevent leaks.
・I was told by another contractor that painting the tiles is impossible, so I would like to confirm if there are any alternatives.

〇 Proposal Details

【2F Surrounding Exterior Walls】
・For the 2F surrounding ceramic siding, we proposed exterior wall painting with premium silicone after replacing the sealing.

【1F Surrounding Exterior Walls】
・For the 1F surrounding tile exterior wall, we proposed exterior wall painting that utilizes the existing tile joints.
・Since the existing material is tile, if we proceed with exterior wall painting as usual, peeling and bubbling of the paint film will occur immediately. Therefore, we applied cationic tight before performing the exterior wall painting.
・Considering moisture permeability, we carried out the exterior wall painting with Perfect Top.

Joint Replacement Work Procedure

1. Removal of Existing Sealing Material

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 and peeling are signs of deterioration! If the bond breaker that prevents three-sided adhesion is peeling, we will apply a new bond breaker.

2. Application of Masking Tape

 

Confirm the position for applying the tape and carefully stick it on 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 of Sealing Material

 

Next, we will apply the sealing. Place the nozzle of the caulking gun against the joint base and fill it sufficiently.

The caulking material used for this work isSunrise / SR Seal H100. It has a durability of about 30 years and is ultra-durable, ultra-low pollution, flexible, and resistant to dirt.

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.

Exterior Wall Painting Work Procedure

1. High-Pressure Washing

 

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

3. Protection of Each Part

Once the high-pressure washing is complete, 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.

3. Tile Damage – Mortar Repair

 

Next, while observing the condition of the tiles, we will shape the mortar for the damaged areas.

4. Tile Exterior Wall – Cation Tight Application

To ensure the paint adheres to the tile exterior wall, we will apply cation tight. If we need to fill the tile joints, we will do so with plastering work, but this time we will apply it with a roller and brush to leave the joints exposed.

4. Primer Application


After completing high-pressure washing and substrate treatment, the first step is to apply the primer paint, which ensures that the middle and top coats adhere well to the surface. By applying the primer thoroughly, you can significantly improve durability and finish quality!

The primer for the siding surface is SK Kaken’s water-based SD Surf Epoxy Premium. It also has substrate adjustment functions, sealing fine cracks!

For the tile surface, we will spray a cationic sealer! We ensured that the sealer penetrates well into the joints!

5. Middle Coat

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

For the tile surface, we will perform spray painting just like with the primer!
Since we wanted to emphasize moisture permeability for the tile surface, we used Perfect Top.

6. Top Coat

Next is the top coat. This is the finishing touch for the exterior wall painting. We will focus on ensuring there are no uneven spots or missed areas, achieving a beautiful finish!

We used SK Kaken’s Escape Premium Silicon for the paint. The manufacturer’s expected durability is said to be about 14 to 16 years.

7. Painting of Auxiliary Parts (Rain Gutter, Eaves, Fascia, Soffit, Canopy)

We will thoroughly paint every detail that can be painted! We will apply rust prevention primer to the metal parts! Since the eaves were made of board material, we will apply a sealer as a primer. [/chat]

Exterior Painting Work Procedure

1. High-Pressure Washing


Before applying the paint, we will thoroughly remove dirt and moss using high-pressure washing! We will also strip away any peeling paint! Neglecting this step can cause the freshly painted surface to peel off. We will wash not only the exterior but also the ground surfaces as well. [/chat]

2. Repairs and Surface Preparation

Since there was a request to eliminate the tile joints on the retaining wall, we performed plastering with cationic tight!

3. Primer Application

 

This is the first step of applying paint after completing high-pressure washing and surface preparation. It involves applying a primer that adheres well to the surface for the middle coat and the finishing top coat.
The primer we use is Safe Sealer!

4. Middle Coat

 

Next is the middle coat. This is a crucial process to ensure the paint performs well, looks beautiful, and eliminates any uneven application!

The paints used are:
Surface: Aica Kogyo / Joripad
Back: International Paint / IP Youheki Coat.

Using the same paint for the retaining wall as for the exterior walls can cause bubbling and peeling, so it is necessary to use specialized paints with excellent moisture permeability, such as Joripad and Youheki Coat!
This time, to reduce costs, we are using Youheki Coat only on the back side.

5. Top Coat

Next is the top coat. This will be the finishing touch for the painting. We will ensure that there are no uneven spots or missed areas, aiming for a beautiful finish! The paint used is the same as the middle coat, Aica Kogyo / Joripad, andInternational Paint / IP Youheki Coat. International Paint / IP Youheki Coat helps maintain the aesthetics of block walls and other surfaces for a long time!
