Exterior 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 waterproofing materials, so we wash carefully. For areas where leaks are occurring, we cleaned by hand instead of using high-pressure washing!

2. Substrate Adjustment

After the high-pressure washing is complete, we will perform substrate adjustments such as repairing the mortar joints of the tiles!

3. Protection of Various Areas

Next, we will protect areas that will not be painted, such as windows, sashes, and floors, using masking tape and other materials. If protection is neglected, gaps may form, allowing waterproofing materials to seep in, or it may result in unsatisfactory clean lines.

4. Primer Coat

This is the first painting task after completing high-pressure washing and substrate treatment. Applying the primer coat thoroughly makes a significant difference in durability and finish! The primer used is Seven Chemical’s Seven S Sealer.

5. Intermediate Coat (Two Coats)

Next is the intermediate coat. The material used for the intermediate coat is the main agent of Seven S, and it will be applied in two coats!

The paint used is Seven Chemical’s Seven S. Seven S is a transparent waterproof finishing material that changes the existing texture very little. It has a long track record of over 25 years and is a trusted transparent waterproofing material.

6. 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 spots or missed areas, aiming for a beautiful finish. The paint used is Seven Chemical’s Seven S Top!

Joint Replacement | Construction Procedure

1. Removal of Existing Sealant

We will remove the existing sealing material using a cutter or similar tools. This is referred to as sealing, caulking, or jointing. It is a crucial area that can easily lead to water leaks, as well as cracks or lifting in the siding. Cracks and peeling are signs of deterioration!

2. Masking Tape Application

Check the position for applying the tape and carefully attach it to avoid any overlap on the surface.

3. Primer Application

Apply the primer with a brush, ensuring there are no missed spots. The primer used is a high-performance urethane primer from Auto Chemical Industry.

4. Filling with Sealing Material

Next, we will apply the sealing. This time, we used Auton Chemical Industry’s Auton Exceed. Auton Exceed is a highly durable sealing material with a lifespan of about 30 years. It offers nearly three times the durability of urethane and silicone-based materials!

※Note:Since Auton Exceed takes time to cure, if you plan to paint the exterior walls after the sealing work, you must allow several days for curing.

5. Trowel Finish

Use a spatula that matches the joint width to press firmly and finish smoothly.

6. Removal of Masking Tape

After finishing, promptly remove the masking tape.

That concludes it.
Once again, we were able to finish beautifully!
