1. Preparation: Before application, ensure the joint surface is dry, clean, and free of oil, water stains, and other impurities. If necessary, clean it with a professional cleaning agent.
2. Mixing the Caulking Agent: Combine the caulking agent powder and the special thinner in the correct proportions and stir thoroughly until there are no particles or lumps.
3. Application: Using a special scraper, apply the caulking agent evenly to the joint to be caulked, applying a little more to facilitate sanding later.
4. Curing: Allow the caulking agent to dry naturally. Wipe off any excess caulking agent with a clean, damp cloth to ensure a smooth, even joint.
5. Sanding: After the caulking agent has completely cured, sand it with sandpaper to achieve a smooth, aesthetically pleasing joint.
