How to Paint a Bike Frame

One of the most frequently asked questions is: how to paint a bike frame? Here is the complete guide for helping you finish the paint job, And make your bike look good again.


No matter how tempted you are to start painting the mountain bike frame without disassembling it, never do it. You will spoil the entire look of your bicycle and would regret it later. The first thing you should do while painting the frame is disassembled the bike until you have the bike frame only.

Everything that’s connected to the frame must be removed. This includes the seat, wheels chain, derailleur, and everything else. To take these off, you’ll require:

  • chain tool
  • Allen wrench (4mm, 5mm & 6mm)
  • Socket wrench
  • Crescent wrench

For painting, you’ll require a clear coat. I used:

  • Blue Krylon Dual
  • Krylon Clear Coat

With these tools, get to it. The great thing about bikes is that every part you’ll need to take off is easy to find. Do you have a hole that can be used to use the Allen wrench? Good, use an Allen wrench! This will take control of the disc brakes and bar stem and the holders for bottles. Make use of the socket wrench to get rid of the crank arms and the crescent wrench to remove the front fork as well as the chain wrench to fix the chain of your bike.

If you’re just beginning to learn about this, make sure you be attentive to all pieces you take off since you’ll be required to return them later on. Be sure to take care to store all pieces. It’s easy to drop small pieces on the route.

Clean the frame:

Before you start painting your bike frame, you should clean it thoroughly to remove any grease or dirt. This cleaning can be as simple as using a damp cloth on the frame. But in some cases, you might also need specific grease-removing agents. The condition in which you keep your bicycle would be the primary determiner here.

Use sandpaper:

You’ll have to roughen up the old paint, so the new one can fit onto it. Scrub the frame with sandpaper, and you’ll get your work done. Don’t scrub too hard to remove the entire paint; a few minutes of scrubbing will do the work.

The grit I chose was 150 but I could have used even finer. The idea is to provide the paint with a smooth surface to hang onto but not to strip away all previous paint.

Cover anything you don’t want to paint:

There can be your bike logo or stickers that you don’t want to spoil with the new paint, you can cover them with anything, so the paint does not touch them. Masking tape or shopping bags could be the right props to hide all such bike components.


Now it is time to paint. You can hang the entire frame with something to get a clear shot. If you don’t have a good place to hang the frame, you can place it on the floor (don’t forget to cover it with paper or a plastic sheet).

Apply 3 coats of paint at least. Once done with each coat, wait for 5 minutes and let the first coat dry.

Spray can VS spray painting gun

Painting is straightforward, however, one important tip is to take your time evaluating the most efficient method of carrying out this task. Spray containers are the least expensive method of making frames look brand new however not everything that sparkles is gold. . In reality, the uniformity of spray produced as well as the coating quality are factors that could impact negatively the final painting result, and can increase the chance of making mistakes significantly. Additionally, their cost isn’t even that cheap! An investment that is slightly more expensive will provide you with a tiny air compressor, and panting gun. This option will be able set the amount of air that escapes through the gun, and disperse over the entire coat.

Tips for painting

Whatever way you prefer, once you’ve selected your paint tool start by working your way through the surface until it’s covered the entire surface with a light coat of paint. Are you still not seeing that first hue? Do not worry about it, the best technique is to apply a few thin coats instead of one thick layer. Take 20 minutes between each application, you’ll reach the quality goal only if you adhere to the time for drying. There’s no set amount of coats that are thin, it’s about continuing until the previous frame is completely coated. Be patient, and you’ll be reimbursed. Most important when painting , move the spray source to the fullest extent without simultaneously getting near enough to your frame to prevent drips.

Once the frame is completely coated and dry, finish the work using a transparent coating What is the best method to shield the bike from corrosion and keep it shining? Repeat the process, allowing time between each application, and repeat the process three times.

Now your bike will be set to rest for 24 hours, and dry in a perfect manner.

Reassembling the bike

Begin by removing the painter tapes you have previously put on and if you’ve completed the taping procedure, you should not be able see any burrs. The entire components you removed prior to putting it on back. Front forks and the seat, handlebars, brakes, the left and right-hand cranks the rear and front derailleurs as well as the bottom bracket, and the wheels.
