To my knowledge, it is a health hazard method, and not usre if your bike suitable for that method.

Hi,

Please note that sandblasting removes a layer of GOOD base material from your frame during the process.

If your bike frame is made of 'soft" ALU-Alloy, it may take away quite a bit....like 0.1mm (subject to type of sand/garnet/grit used, blasting air pressure, skill of the blaster etc). If your frame material thickness is 1.0mm => 20%, if 2.0mm => 10% etc....

As frames are generally circular in shape, 01.mm is the reduction in radius.....meaning; gone 0.1mm x 2

This weaken the frame exponentially......so do note this in your rides after that.

The other options are:

- chemically remove the paint/coating (but I dun know the processes or what or how it will affect the GOOD base materials of the frame).

- hydro blasting: This method is much better as it will remove the paint coating without removing the GOOD base material of the frame. Depending of what type of coating, the water pressure varies but are usually in the High Pressure Water range (10k-15k psi) or Ultra-High range (20k-35k psi)

Whichever method you intend to use; I still think that it will be expensive relative to the market price of your bike frame unless you have a special Titanium-Alloy Bike Frame....if not, it's just an unproductive excerise...in my opinion.

However, do let us know the cost if you do check/consult with Rebound Centre.....I am just equally curious about it. Thank you.

Thanks IvanLim. Your information on different methods of removing paint from our beloved bicycle frames is of great help to us. I've just checked with rebound center about the cost of stripping and painting a suspension fork and a hard tail mtb frame (single colour) is ard 420 and takes about a week.
