Permanently paint a garage door


Painting a garage door can serve two different purposes. The paint itself can be used as a coloring decoration or it is applied as the most transparent, protective layer. High quality 2-in-1 paints can be skimmed directly without previous primer coat.

Protective coating for many colors

If you want to paint a garage door in one color or in several colors, you can do it directly with a special garage varnish. Modern acrylic coatings do not need an additional protective lacquer layer. If, however, many different colors are to be used or the garage door is painted with motifs, a primer and a final transparent protective coating are recommended.

The individual color transitions and line courses of a coating pose a potential risk of leakage. In the microscopic size range, two color layers "collide" here with their terminating edges. If the edge has only the smallest, often invisible, holes or uncovered surfaces, these spots become potential rust or paint breakage risks. A complete paint seal eliminates this risk.

Garage lacquers for all door leaf materials

Special garage door lacquers withstand all requirements against weather conditions and temperature fluctuations. The modern coatings are suitable for ferrous steel surfaces and often also for non-ferrous metals such as aluminum. They are available in almost infinite color choices and range from high-gloss over normal gloss to matt and semi-matt appearances.

How to paint your garage door

  • 750 milliliters of garage paint for five square meters painted twice
  • Maybe primer
  • Abrasive (120 grit)
  • soapsuds
  • Ammonia-containing zinc cleaner as needed (e.g., ammonia)
  • wire brush
  • Grinding block or grinding machine
  • Hand Brush
  • Synthetic fleece sponge
  • Natural bristle brushes
  • Plastic paint roller
  • masking tape
  • pencil
  • Mouth and eye protection

1. Clean

Sweep the garage door with the hand brush and remove any loose and coarse dirt with a wire brush. Remember the profile corners and edge edges and also remove peeling old paint or old paint.

2. grinding

Strain 120 grit sandpaper onto the sanding block or grinder and thoroughly remove any rust and old paint. Grind the entire surface slightly after the targeted processing of the damaged areas.

3. Possibly priming

Depending on the selected paint, you may need to prime the garage door first. Spread the primer evenly from top to bottom.

4. Draw guides

If you want to create a geometric pattern or a subject by painting, draw the necessary guides with a pencil. Mask the first surface to be painted with masking tape.

5. Change surface

After the uniform thin paint application according to the manufacturer's instructions, wait until the paint has dried to a tolerable extent. Then glue off the edges of the already painted surface and paint the next segment.

6. Protective coating

When all surfaces have been painted, after two passes they usually cover well, cover the entire garage door with a transparent layer of protective lacquer.

Tips & Tricks

Different gloss effects can be generated by the combination of the color and protective varnish. Matte to high gloss and vice versa, high gloss to high gloss or matt to matt enhances the respective effect or develops refractive lighting effects.
