Construction Process:

1. Basic Treatment for Aging Walls

Primarily refers to the removal of existing wall finishes and decorations. Typically includes scraping off latex paint and joint compound, removing wooden trim, and dismantling other decorative items. If the wall has been decorated for only one to two years, the water-resistant joint compound on the wall may not need to be completely removed. After sanding and brushing the wall with steel wool, it can be repainted with latex paint.

2. Basic Steps for Renovating Old Walls

Step 1: Wall Cleaning

Before renovating old walls, the first step is to treat the wall base. Severely flaking paint should be completely removed, and then a layer of white cement should be applied. For walls previously painted and excessively smooth, sanding is required after removal to remove loose, adherent layers, facilitating better adhesion of new paint to the wall.

Step 2: Apply Primer

The role of wall primer is to seal the base material, resist alkalinity and moisture, protect the topcoat, and enhance the texture and coverage of the topcoat. For renovating old houses, it is essential to apply wall primer; otherwise, if the topcoat is applied directly, bubbles and mold may appear over time, and the wall may also discolor after prolonged sun exposure.

Three Steps: Large-Scale Repair

Repairs to walls that have already been painted with topcoat can be quite麻烦, prone to color discrepancies. The varying times of material usage and uncertain quality also cannot guarantee ideal results. Therefore, it's best to repair the entire wall or opt for large-area repairs whenever possible, to minimize color variations.

Four Steps: Color Difference Prevention

Please follow the instructions on the paint can for mixing and application, and ensure accurate measurement. Prepare enough quantity in one go to maintain consistent wall color and avoid discrepancies in repainted areas.
