Delete a bike - that's the result


If the old bike has some unsightly spots, or if you want to visually rebuild it with an effect paint, you can repaint the frame. For the result to be perfect, however, it is necessary to proceed professionally. How this works is shown in this article.

The most important points

  • dismantling
  • the grinding
  • the right color
  • the paint protection

dismantling

The bike is only painted the frame. All other parts must be dismantled before. In particular, chrome-plated parts must be removed.

The frame must be suspended so that it is accessible from each side and has no support points.

grind

The better the sanding, the better the quality of the paint job. For still reasonably intact paints, sanding with fine metal sanding paper (120 grit) is sufficient.

Rust spots must be completely sanded off. If there is rust, pre-sand the entire frame with coarse sandpaper (80 grit) and then sand with fine paper (120 grit).

Frames with particularly severe rust damage should be sandblasted and completely stripped. Under the new paint then primer is first painted.

The right color

For brush painting, matt and semi-glossy colors are best suited. High-gloss paints almost always create an appearance that clearly shows that the bike has been repainted.

Car paints can be used, but almost always need a corresponding spray unit for a good result. Spray can colors are difficult to process. Paint noses and dripping points are difficult to avoid.

The paint protection

After painting, a clear coat should be applied to protect the paint. Special products, which are also used for car paints, make the paint more resistant.

Paint the bike frame perfectly - that's how it goes in turn

  • Lacquer matt or semi-gloss
  • clearcoat
  • Sandpaper 80 grit, if necessary
  • Sandpaper 120 grit
  • Dismantling tool
  • paint roller
  • brush
  • Suspension for the frame

1. Disassemble the bicycle

Remove all attachments. Remove the pedals and carefully cover the bottom bracket. Place the frame on a base for sanding

2. Grind the frame

Grind rust spots completely with coarse sandpaper. Pre-sand the entire frame with coarse sandpaper (80 grit). If the frame is stainless and the paint is still intact, this step can be omitted.

Finely sand with fine sandpaper (120 grit). In particular, grind very carefully in the corners and at the welds of the frame. Remove the grinding dust completely.

3. Apply first coat of varnish

Apply thinly the first coat with a brush, paint roller or sprayer. Pay attention to uniform paint application.

Then leave the paint to dry for 24 hours.

4. Apply second coat of varnish

Sand with fine sandpaper. Remove the grinding dust completely. Apply second layer of lacquer thinly and allow to dry for 24 hours.

5. Apply clearcoat

Clear lacquer, if desired or necessary also lacquer hardener, according to manufacturer's instruction and let dry. After drying, the bike can be reinstalled.
