ᐅ What should I consider when painting Ikea BESTA furniture to achieve a durable finish?

Hello everyone, I want to paint my Ikea Besta furniture to give it a fresher and, above all, more durable finish. However, I’m wondering which preparations and steps are really necessary to ensure that the paint not only looks good but also lasts long. My main concerns are the smooth plastic surfaces and edges, which are not exactly ideal for painting. What type of primer is best, how should sanding be done, and which types of paint are recommended? I’m also curious about the proper drying times and whether intermediate sanding is needed. I’m looking forward to practical answers and tips so I don’t miss anything important and end up with a finish that is prone to damage.

Hello, I can provide you with some important tips based on my experience that are particularly crucial for your question. Unlike untreated wood, the surface of Ikea BESTA is usually melamine-coated or made of plastic, which makes adhesion more difficult. Therefore, proper preparation is key:

- Thoroughly clean the surface to remove grease and dust. It is best to use a cleaning agent that does not leave any residues.
- Lightly sand with fine-grit sandpaper (grit 220 to 320) to create a rougher surface for the primer.
- Use a special adhesion primer designed for plastics to ensure the paint adheres properly.

For the paint, I recommend a solvent-based acrylic or two-component (2K) coating, as these are more durable than simple water-based paints. Sanding between coats improves the surface quality.

It is also important to allow sufficient drying time, at least 24 hours, and to work in a dust-free and not overly humid environment to achieve the best results.

You hit the nail on the head! For such smooth surfaces, thorough preparation is essential, otherwise everything will peel off later. A small tip from me: after sanding and priming, you can gently go over the surface with a very fine sanding pad before applying the final coat of paint. This improves adhesion even more and creates a wonderfully smooth finish.

Also, it’s worthwhile to apply the paint in thin layers. Thick coats tend to crack or run, which not only looks old but also reduces durability.

If you’re using a brush, make sure to use high-quality brushes, or even better, a spray gun if you have access to one. This helps avoid brush marks and achieves a better surface.

I would like to organize and expand the previous tips to achieve the most durable results when painting Ikea BESTA furniture:

- Surface condition: Since these are mostly melamine-coated particle boards, paint adhesion is limited without proper surface preparation.
- Cleaning: Remove grease, silicone residues, and dust with appropriate cleaning agents (e.g., isopropanol).
- Sanding: Lightly roughen the surface using very fine sandpaper (320 grit). Avoid sanding too aggressively to prevent completely removing the coating.
- Priming: Use adhesion promoters based on plastic or primers specifically designed for melamine surfaces. These are essential for bonding between the surface and the paint.
- Paint type: Two-component acrylic or polyurethane paints offer good abrasion resistance and UV stability. Solvent-based paints are more durable than water-based ones.
- Application: Apply thin layers with light sanding (400 grit) between each coat to ensure smooth surfaces and good adhesion.
- Drying: Ideally dry at 20-25°C (68-77°F) with adequate ventilation. Full curing may take several days.

These points are based on extensive testing and ensure a durable and attractive finish.

Summary:

- Clean
- Fine sanding (320)
- Apply primer for plastic
- Thin coats of paint with intermediate sanding (400)
- Be patient during drying

That’s all it takes for a durable result.

Thank you for the precise summary, RENMA. I am still wondering if the same process applies to edge coating as for the surfaces? With BESTA, the edges are sometimes slightly rounded and appear to be made of a somewhat different material. Is a different primer or coating type required, or is the standard method sufficient? I want to avoid the paint chipping or wearing off more quickly on the edges.
