Construction Process:
1. Basic Treatment for Aging Walls
Primarily refers to the removal of existing wall decoration. Generally includes the scraping of latex paint and joint compound, the removal of wooden trim, and the dismantling of other decorative items. If the wall has only been decorated for one to two years, the water-resistant joint compound on the wall does not need to be completely removed; after sanding and brushing the wall with steel bristles, it can be repainted with latex paint.
2. Basic Steps for Renovating Old Walls
Step 1: Wall Preparation
Before renovating old walls, the first step is to treat the wall base. Severely powdery areas should be entirely removed, and then coated with white cement. For walls previously painted and excessively smooth, sanding is required after removal to remove loosely adhered surfaces, facilitating better bonding with the new paint.

Two-step: Apply Base Coat
The role of wall primer is to seal the base material, resist alkali and moisture, protect the topcoat, and enhance the texture and coverage of the topcoat. For renovation of old houses, it is essential to apply wall primer. If topcoat is applied directly, over time, the wall may develop bubbles and mold, and it can also fade easily when exposed to sunlight for extended periods.
Three Steps: Large-Scale Repairs
Wall repairs with pre-painted surfaces can be麻烦, prone to color discrepancies, and the material usage and quality are uncertain, thus cannot guarantee ideal results. Therefore, it's best to repair the entire wall or opt for large-scale repairs as much as possible to minimize color variations.
Four Steps: Color Difference Prevention
Please follow the instructions on the paint bucket for mixing and application, and ensure the amount used is estimated correctly. Prepare an adequate quantity in one go to ensure consistent wall color and avoid discrepancies in the color of the re-mixed paint.
