Bike painting. Answered

Is it o.k. just to sand a bike, with light grain sandpaper (so as not to scratch) to paint the bike?  I am paining from almost "white" colore to a darker colore.  Any help, sure would be appreciated.

Lightly sand, clean the surface, dry it, paint it. You won't need primer if the old paint is ok. Follow the instructions on the paint can for number of coats, time between coats, and drying time.

If you want a really good finish in the end, then you really ought to take the bike apart, down to the frame and sand it well. Then make sure to clean away all the dust (AND any rust) and give it a good rust proofing primer coat (with a sprayer, not a brush). Then spray coat your bike in the color you want, and for even better protection, add finish coats in clear. (Ensure you follow directions for drying times, and work in a fairly dust free environment).

Painting a bike is much like painting a car, and you'll get better results if you do it right. If you're not that concerned with the outcome, then by all means, tape off the areas you don't want painted and do it that way, but regardless, don't use a brush. It's virtually impossible to get a good finish that way.

Well, I want it to look professional, but if I take the bike apart....I will never get it back together with all those gears. Maybe I will have someone take it apart and put it back together for me. It has a lot of gears, and it is not a single chain bike or 3 speed. someone told me to use sponge brush and I was going to use that....but now I don't know. I am going to look into having someone take it apart for me. I know it is important, all that time spent on it, sanding, rust proofing primer coat.....(I guess I go to any Home Depot for that?). I do want it to look nice and will definitely think about adding finish coats in clear.
Thanks for your help. The hardest part is taking it apart and putting it back together and hoping it still works as good as it always has.

I agree that taking the bike apart may be the toughest task, but like you said, you want a professional result, so the reward is worth the effort. Ask around at some bike shops and see what they'll charge to help you disassemble and then reassemble your bike. They may have some new employees that could use the training, and may not charge you much. If you do try it alone (or get the help of a friend), just make sure you're prepared. Take a ton of photos while you're taking the bike apart and ensure that every part is bagged and labeled so there is no guess work when putting things back together.

From that point, you want to make sure you're using the right materials. Home Depot should have most of what you need, but there is also automotive stores to look at as another option.

Here's a link to more info on the actual prep work and painting (in case you need the additional help).


So then I don't have to use a primter or paint remover? I have the sandpaper and have started sanding it. I haven't opened the can of Rock-Miracle Paint & Varnish Remover that I bought. If all I have to do is sand, to ruff it up, then I won't need this caustic, toxic paint remover? Also, I'm not taking the bike apart. I am going to try to use the sponge brushes to apply the paint and hope it works. The spray paint, I have considered, but can't get the color I want in the spray paint. I guess I could always buy a spray container, but then I would definitely have to consider taking the bike apart.
Thanks for your answer.

Weather or not a primer coat is needed will depend on the pain you use. But its always a good idea to primer it first.

yup just like painting a car SAND IT AND SHOOT IT.

good luck


The whole point of sanding is to ruff up the surface so the paint has something to hold too. Just like painting anything else you will need several coats of paint. Let the paint dry for as least 12 hours between coats.
