Joint Replacement Work Procedure
1. Removal of Existing Sealing Material
This is referred to as sealing, caulking, or joints. 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. Protection (Masking Tape Application)
3. Application of Primer
4. Filling with Sealant

5. Finishing with a Trowel
6. Removal of Masking Tape
We were able to finish beautifully this time as well!
Exterior Painting Work Procedure
1. High-Pressure Washing


With bio-cleaning, we thoroughly remove dirt and moss! Unlike high-pressure washing that removes dirt with water pressure, bio-cleaning mixes chemicals to clean bacteria, mold, and roots of plants thoroughly!
We also took the opportunity to clean the tiles!

In order to bring out the performance of
5. Top Coat

This is the finishing touch for


6. Painting of Auxiliary Parts (Shutter Box, Water Cutting, Eaves, Rain Gutter)
Shutter Box

Water Cutting Metal

Eaves
・Rain Gutter
We will thoroughly paint every detail that can be painted! For metal parts, we will apply rust prevention paint before the topcoat! [/chat]
Balcony Waterproofing Construction Procedure
1. Surface Preparation and Roughening
To improve the adhesion of the paint, we will create fine scratches on the surface to be painted! This is known as surface treatment! We will roughen the smooth surface![/chat]
2. Acetone Wiping
Next, we will perform acetone wiping! This is also an important surface 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 (Base Coat)
The primer acts as an adhesive that promotes the adhesion between the waterproof layer and the topcoat![/chat]
4. Topcoat Application
Top coat is applied in two layers as a standard!
Once finished, we will check for any missed spots.
5. Completion of Balcony Waterproofing Work
