To paint over existing gloss with a new coat of gloss, the quickest and easiest method is typically sanding.
Preparing Gloss for Repainting
Before applying new gloss paint over old gloss, proper preparation is key to ensure a smooth and durable finish. Here's a step-by-step guide:
Sanding the Existing Gloss
According to the provided reference, sanding over the existing gloss is usually the quickest and easiest solution if the paint is in relatively good condition (chip-free and not flaking).
- Use fine-grit sandpaper (e.g., 220-grit) to gently roughen the surface of the existing gloss paint.
- Sanding creates a "key" for the new paint to adhere to, preventing it from peeling or flaking.
- Ensure that you have sanded the entire area you wish to paint.
- Wipe down the sanded area thoroughly with a damp cloth to remove any dust.
Other Preparation Steps
While sanding is usually the main preparation, consider the following:
- Cleaning: Clean the surface with a degreaser to remove any grease or grime. This allows the new paint to adhere properly.
- Repairing damage: If there are any chips, dents, or holes, repair these before painting. Use a suitable filler and sand it smooth once dry.
- Tack cloth: Wipe over the surface with a tack cloth to ensure all dust is removed.
Applying the New Gloss Paint
Once the existing gloss is prepped, you can apply the new gloss paint:
- Use a good-quality brush or roller suitable for gloss paint.
- Apply the paint in thin, even coats. Avoid overbrushing or over-rolling, as this can lead to brush strokes or an uneven finish.
- Allow each coat to dry completely before applying the next. Follow the manufacturer's instructions regarding drying times.
- Typically, two coats of gloss paint are needed for optimal coverage and durability.
