A practical step sequence for renovating existing tile using the published Shunfengshan renovation-paint technical sheets.

Direct answer
Confirm the tile substrate is sound, free of active leaks, and can be cleaned and abraded; approve an adhesion and color sample; then apply two roller or spray coats under the stated temperature and humidity window. Fully polished or glazed tile requires a reviewed adhesion method before large-area work.
Step 1: Decide if renovation is suitable
Exclude hollow, loose, leaking, or heavily contaminated surfaces that cannot be cleaned. A decorative finish does not replace waterproof or structural repair.
- Fix hollow or loose areas first
- Investigate leaks
- Separate wet and dry zones
- Keep substrate photos
Step 2: Clean, degrease, and abrade
The published sheets require removing dust, oil, and failed coatings, then light abrasion. Highly smooth polished or glazed tile needs a reviewed adhesion method.
Step 3: Approve a small sample
Validate cleaning, abrasion, adhesion, color, tools, and cleaning response before locking the system.
- Stable adhesion
- Accepted color
- Clean edges
- No dusting or mottling after cleaning
Step 4: Apply two coats under stated conditions
Both one- and two-component sheets specify two roller or spray coats above 10°C and below 75% RH with ventilation.
Reference values at 25°C and 50% RH are about 30 minutes touch dry, four hours to recoat, and 24 hours through dry.
Step 5: Cure before water-and-wear judgment
Avoid scratching and soaking before full cure. The sheets use seven days before assessing improved water and wear performance. Inspect coverage, edges, details, and cleaning—not color alone.
Frequently asked questions
How many coats are usual?
The published sheets specify two roller or spray coats, subject to sample and acceptance needs.
Can glazed tile be coated directly?
Not with a generic method. Confirm adhesion and approve a sample first.
How should coverage be used?
About 1 kg per 5–6 m² for two coats. Add substrate, loss, and contingency when ordering.
