Painting silk over gloss requires proper preparation to ensure the paint adheres correctly and achieves a smooth, long-lasting finish. The key is to create a surface that the silk paint can grip onto, since gloss paint is very smooth and non-porous.
Preparation is Key
The biggest challenge when painting silk over gloss is that gloss paint is inherently difficult for new paint to stick to. Therefore, some preparation is needed:
- Sanding:
- The first, and most recommended, step is to sand down the gloss surface. This removes the sheen, creating a rougher texture that will provide a better grip for the silk paint. You don't need to remove all the gloss paint, just roughen the surface.
- Use fine-grit sandpaper to avoid damaging the underlying surface.
- Alternative to Sanding:
- If you would like to avoid sanding, you can use a coat of Zinsser Cover Stain, which will adhere to the gloss surface and provide a good base for the silk paint.
Painting Silk Over Gloss
Once you have prepared the surface, you can proceed to paint with silk paint.
- Apply Primer (If Needed): If you have sanded the gloss, using a general primer might be beneficial. However, if you've used Zinsser cover stain, it acts as a primer itself.
- Apply Two Coats of Silk Paint:
- Apply two coats of your chosen silk paint. Allow adequate drying time between coats.
- Ensure each coat is applied evenly for a consistent and durable finish.
- A brush is suitable for smaller areas, but a roller may be easier for larger sections.
Why This Approach?
- Adhesion: The primary reason for sanding or applying a special primer is to improve the adhesion of the silk paint. Gloss paint's smooth surface doesn't provide sufficient grip for new paint.
- Durability: Proper preparation helps the new paint adhere better, making it less likely to chip or peel.
- Finish: Following these steps will achieve a more professional and smoother finish.
Recommended Actions
| Action | Why? |
|---|---|
| Sanding the gloss | Creates a rough surface for better paint adhesion |
| Zinsser Coverstain (if not sanding) | Acts as a bonding primer and allows for silk paint adhesion |
| Two coats of silk | Provides the most professional and durable finish |
By using these methods you should be able to paint silk over gloss.
