🏠 Why repainting a wall that has already been painted is not always that simple ?
A wall that has already been painted may seem ready to receive a new coat. However, poor preparation can lead to a lack of adhesion, streaks, poor coverage, or an unsustainable result..
Whether the existing paint is matte, satin, or glossy, a few checks can help achieve a professional finish.
👉 Discover why choosing Maestria paints will provide you with professional quality and excellent durability.
🔎 Step 1 : How to prepare a previously painted wall before repainting it ?
Before starting, assess the condition of the wall :
✔️ is the paint healthy ?
✔️ are there any cracks ?
✔️ holes ?
✔️ stains ?
✔️ is the paint peeling ?
✔️ is the wall washable or powdery ?
👉 If the paint is peeling, all non-adhering parts must be removed before repainting..
🧽 Step 2 : Carefully clean the support
Even if the wall looks clean, it often contains :
- dust
- fat
- nicotine
- kitchen traces
- pollution
A cleaning ensures better adhesion of the new paint.
🔧 Step 3 : Fix the defects
Replug :
- trousers
- cracks
- impacts
Then :
- sanding
- dusting
The surface must be perfectly smooth.
🎨 Step 4 : Should a primer be applied before repainting a wall? ?
Not always.
A underlayment is recommended when :
✔️ the support is very porous
✔️ An old painting is very bright
✔️ the color changes significantly
✔️ The wall has significant repairs.
🖌️ Step 5 : Which paint to choose for repainting a wall? Choosing the right finish
