pressure washing paint off

[peecook]

tried sand blasting on the M109, went through 10 bags and barely made a dent. was told a pressure washer with 4000 psi and a 45 degree tip would take it right off. just wanted to see if anyone else had any luck with this process or any other suggestions.

ya pressure washing does this well. i took paint off my frame w/it.

 

[peecook]

do you remember what psi you used?

 

[oldshep]

i think 3000 or 4000. I might have used a 0 degree tip. it made the paint fly pretty good.

Did that put any holes in the body???

The only way a pressure washer will eat steel is with sand injection and 20,000+ psi. It can break glass at almost any pressure. On a safety note being cut by high pressure water is an injection wound not a regular cut. It has to be cleaned and irrigated like a needle stab.

That's a pretty important detail to note. I guess I can't skimp off on my monthly shower that way...

It is going to take more than just 4000 PSI and a point nozzle to pull paint off of mine. Works slowly on weathered CARC.

Might take me 100 gallons of gasoline to do the entire truck. I'm going to try the sand attachment.
