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 and peeling are signs of deterioration!

If there are areas where the bond breaker preventing three-sided adhesion has come off, we will apply a new bond breaker.

2. Protection

Next, we will carry out protection using masking tape and other materials. This is done to prevent dirt on the exterior walls and to define the finish line.

We will carefully apply the tape, ensuring it does not dig into the surface.

3. Application of Primer

To enhance the adhesion between the sealing material and the substrate, we will apply primer to the work surface using a brush or similar tool.

4. Filling the Sealing Material

Next, we will apply the sealing. Position the nozzle of the caulking gun at the bottom of the joint and fill it sufficiently.

The caulking material used for this work is Sunrise / SR Seal S70. SR Seal S70 is a non-bleed type that is less likely to cause joint contamination, making it a high-performance sealing material suitable for exposed joints as well as for painting substrates.

Sunrise / SR Seal S70

5. Trowel Finishing

Use a trowel that matches the width of the joint to press down firmly and finish smoothly.

6. Removal of Masking Tape – Completion of Joint Replacement Work

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

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 it carefully. We will also wash the exterior structures, concrete floors, and inside the rain gutters as well.

2. Substrate Adjustment

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

3. Protective Measures

Next, we will protect areas that will not be painted, such as windows, sashes, and floors, using masking tape, blue sheets, and poly masks. This is a very important task in the painting process!

Neglecting protective measures can create gaps, allowing paint to seep in or resulting in uneven lines.

4. Primer Coat

This is the first application of paint after completing high-pressure washing and substrate treatment. It is 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 primer used is Nissin Sangyo / GAINA Multi Sealer. This is a GAINA (ガイナ) exclusive primer developed in collaboration between Kikuchi Chemical Industry Co., Ltd. and Nissin Sangyo Co., Ltd., featuring excellent adhesion durability.

5. Middle Coat

Next is the middle coat. This is a crucial step to bring out the performance of the paint, achieve a beautiful finish, and eliminate uneven application!

The paint used is Nissin Sangyo / GAINA (ガイナ), which is characterized by its high insulation and heat shielding properties!

6. Top Coat

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

The paint used is the same as the middle coat, Nissin Sangyo / GAINA (ガイナ).

7. Painting of Additional Parts (Bathroom Ceiling, Slim Duct, Rain Gutter, Entrance Door)

Bathroom Ceiling

Rain Gutter

Entrance Door

For the painting of the bathroom ceiling, we used Nissin Sangyo / GAINA, just like for the exterior wall painting. After protecting the areas that will not be painted, we apply the primer, middle coat, and top coat.

For other attached parts, after finishing the surface preparation such as scraping, we apply a rust preventive in the primer for iron parts, and then use Rock Paint / Yumelock for the middle and top coats. We make sure to paint even the smallest areas thoroughly!

Additionally, we disassemble the slim duct to prevent it from sticking together during painting. By detaching and painting, we can also ensure that the exterior wall beneath the slim duct is painted properly! [/chat]
