Construction Process:

1. Basic Treatment for Old Wall Surfaces

Primarily refers to the removal of existing wall finishes and decorations. Generally 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. Simply sand and brush the wall with steel bristles before repainting 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. For walls with severe powdering, remove all the paint. After removal, apply a layer of white cement. For walls that have been painted and are excessively smooth, sanding is required after removal to remove loose coatings, facilitating adhesion between the new paint and 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 renovation of old houses, applying wall primer is a must. If the topcoat is applied directly, over time, the wall may develop blisters and mold, and it can also easily fade with prolonged sun exposure.

Three Steps: Large-Scale Repairs

Repainting walls that have already been coated with finish paint can be quite tricky, as it's prone to color mismatches. The varying time of material use and uncertain quality also prevent ensuring an ideal outcome. Therefore, it's advisable to repair the entire wall or opt for large-area repairs as much as possible to minimize color discrepancies.

Four Steps: Color Difference Prevention

Please follow the instructions on the paint bucket for mixing and applying the paint, and ensure accurate estimation of the amount needed. Prepare enough in one go to ensure consistent wall color and avoid discrepancies in the color when repainting.
