Have you decided to give new life to a shiny support through painting? Follow this practical guide to get a perfect finish!
Prepare the Surface
To obtain a perfect finish on a glossy support, the first thing to do is carefully prepare the surface.
This means cleaning the area with specific soap to remove grease and dirt. If necessary, use wood filler to fill any cracks or imperfections and allow to dry completely.
Once dry, sand the filler with 120-grit sandpaper, then go over the entire surface with 180-grit sandpaper. This process ensures that the shine is completely removed, making the substrate ready for painting.
Application of the Fund
The next step is to apply one bottom layer. Use a two- to three-inch brush to apply the primer and let it dry following the manufacturer’s instructions.
It is important to check that the primer covers the surface evenly. If necessary, apply a second layer.
- Sand lightly between layers with 220-grit sandpaper.
- If working on bare wood, apply a primer first, followed by two coats of primer.
Application of the finishing paint
To complete the job, apply a layer of finishing paint (for example, glossy, satin or eggshell) and allow to dry completely. Usually, one layer is sufficient, but if necessary, apply another layer after 24 hours.
Painting on existing glossy paint
While it is possible to paint directly onto a glossy surface, it is not recommended. The glossy surface does not offer good adhesion for the new paint, which therefore risks peeling off easily.
If the gloss paint is in good condition, clean it with specific soap and sand lightly with fine-grit (220) sandpaper. This will improve the adhesion of the new paint.
Removing Old Gloss Paint
If the glossy paint is in poor condition, it is best to remove it. There are two options: use a paint stripper or one Thermal gun. The paint stripper is ideal for intricate surfaces, while the heat gun is more effective and economical for elements such as windows, doors and skirting boards.
- Use one scraper to remove softened paint.
- Read the heat gun instructions and practice on a small, hidden area.
Painting on peeling glossy paint
You can paint over peeling paint by following a few steps. First of all, remove any paint chips with fine-grit sandpaper. Apply a thin layer of primer and let dry.
Repeat the process with another layer of primer, sand lightly and finally apply the finishing varnish.
Choice of Paint
If the surface is prepared correctly, almost any type of paint can be used as a final coat. However, it is advisable to opt for glossy, satin or eggshell paintswhich offer a durable and long-lasting finish.
If you want to use an emulsion paint to match the color of your walls, be aware that it will not last as long as the ones mentioned above.
