TB135 Mini Excavator Repainting Guide

[MikePhua]

In the life cycle of construction machinery, maintaining the exterior is just as important as maintaining its performance. For mini excavators like the TB135, prolonged usage can lead to wear and tear, scratches, or rust buildup on the body. Repainting is an effective way to solve these issues, not only extending the life of the equipment but also enhancing its appearance. This article provides a guide on how to repaint the TB135 mini excavator, including preparation steps, painting procedures, and maintenance tips.
Importance of Repainting

1. Enhancing Appearance
   With time and exposure to harsh environments, the exterior of the TB135 can suffer from various damages, such as scratches, peeling paint, and rust. These damages can reduce the machine's aesthetic appeal and even affect its resale value. Repainting can restore the machine to its original look and improve its overall appearance.
   
2. Protective Function
   Beyond aesthetics, repainting provides an additional layer of protection for the equipment. A fresh coat of paint helps prevent rust, corrosion, and other environmental factors from damaging the surface. In humid or rainy environments, a well-applied paint layer acts as a protective barrier to prevent metal oxidation and extend the equipment’s lifespan.
   

Preparation for Repainting

1. Choosing the Right Paint
   Selecting the appropriate industrial-grade paint for mini excavators is crucial. The paint must have good weather resistance, oil resistance, and corrosion protection, especially for outdoor machinery. High-quality paint ensures long-lasting results and reduces the need for frequent touch-ups or maintenance.
   
2. Cleaning the Surface
   Before applying paint, the TB135 must be thoroughly cleaned. Use a pressure washer or industrial cleaning solution to remove dirt, grease, old paint, and rust. The surface should be completely dry before painting to ensure the paint adheres properly and avoids peeling or bubbling.
   
3. Repairing Surface Damage
   If there are large scratches or dents on the surface, use sandpaper or metal filler to repair the damage. Sand down the affected areas to create a smooth surface, ensuring even paint coverage. For extensive rust, use a wire brush to clean the surface, or apply a rust-proof primer.
   

Repainting Process

1. Applying Primer
   The primer is a key step in the painting process as it enhances paint adhesion and increases corrosion resistance. Use a rust-proof primer specifically designed for metal surfaces, applying it evenly across the TB135’s body. Once the primer has dried, sand the surface to ensure smoothness.
   
2. Spraying Topcoat
   The topcoat is the finishing layer that provides color and the final protective coating. Use a spray gun to apply the topcoat evenly, ensuring that the paint is spread uniformly across the surface. It is advisable to apply two to three layers of topcoat, waiting for each layer to dry before applying the next one.
   
3. Drying and Curing
   After the final coat of paint, allow the machine to rest in a well-ventilated area for several hours to ensure the paint dries properly. For industrial-grade coatings, it may be necessary to use professional drying equipment to accelerate the curing process. Be sure to allow the paint to fully cure before handling the equipment to prevent scratches or peeling.
   

Post-Painting Maintenance

1. Regular Inspections and Care
   While repainting improves both the appearance and protection of the machine, regular inspection of the surface is still necessary. Check for any new scratches, dirt, or other damages and address them promptly. Small chips or cracks should be touched up immediately to prevent them from spreading or worsening.
   
2. Avoiding Heavy Impacts
   Although repainting provides added protection, it’s important to avoid rough contact with sharp or hard objects during operation. Take care to prevent the equipment from colliding with obstacles that could damage the paint or expose the metal underneath.
   

Conclusion
Repainting the TB135 mini excavator not only improves its appearance but also enhances its resistance to rust, corrosion, and other environmental elements, thus extending its service life. By choosing the right paint, preparing the surface properly, and following the correct painting techniques, you can achieve excellent results. Additionally, regular inspections and proper maintenance will help preserve the paint's longevity. If you want to revitalize your TB135 and improve its performance, repainting is undoubtedly a valuable investment.
