Joint Replacement Construction Procedure
1. Removal of Existing Sealing Material
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!
2. Applying Masking Tape
3. Application of Primer
4. Filling with Sealing Material
5. Finishing with a Trowel
6. Removal of Masking Tape
This time, we were able to finish beautifully without any issues!
Exterior Wall 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 complimentary cleaning of the ground and inside the rain gutters!
This time, we performed high-pressure washing using bio-cleaning.
2. Substrate Adjustment
3. Protection of Surrounding Areas
4. Primer Application

After completing high-pressure washing and substrate treatment, we begin the first application of paint, which is the primer. This primer ensures that the middle and top coats adhere properly to the surface. A thorough primer application greatly impacts durability and finish quality!
This time, we used Astec Paint’s Epithic Filler as the primer.
5. Middle Coat
The paint used for the middle coating this time is Astec Paint’s Silicon REVO1000-IR.
6. Top Coating

This time, the paint used for the top coating is the same as the middle coating, Astec Paint’s Silicon REVO1000-IR.

7. Accessory Painting (Eaves, Water Cutting, Storm Shutter Boxes, Nose Hiding)
Eaves


The eaves are less exposed to sunlight and therefore less prone to deterioration, but due to the lack of sunlight, they tend to be more susceptible to moss and mold. For this reason, we use paint with high anti-mold and moisture-permeable properties for the eaves.
The paint used is Nippon Paint/Ken Ace.
Water Drainage

Shutter Box
Fascia Board
Balcony Waterproofing Construction Procedure
1. Surface Preparation and Roughening
To improve the adhesion of
2. Acetone Wiping
Next, we will perform acetone wiping! This is also an important substrate treatment. Acetone wiping involves removing the oil film from the FRP waterproofing surface! Skipping this step can lead to paint peeling.[/chat]
3. Primer Application (Undercoat)
The primer acts as an adhesive that promotes the adhesion between the waterproof layer and the topcoat![/chat]
4. Topcoat Application
The topcoat is generally applied in two layers!
After finishing the application, we will check for any missed spots. [/chat]
5. Completion of Balcony Waterproofing Work
Once the balcony is dry, the work is complete![/chat]

Summary
These are the results of our exterior painting, sealing work, and balcony waterproofing work in Tachikawa City!
This time, we used paint that improves the heat insulation of the exterior walls, and you should be able to feel the effects during the summer!
The most important part of exterior siding is the joint sealing material.
If the joint sealing is cut, it can lead to leaks and internal wood decay, as well as warping and cracking of the siding material.
Even if exterior painting is difficult cost-wise, we recommend at least repairing the joint sealing as an emergency measure.
Kakeru Koumuten Co., Ltd. is happy to assist with emergency measures and partial repairs.
The customer was very satisfied after confirming the finish of the painting and joints!
