Im sure people have different methods of doing everything.
For instance, when switching from a striper from waterborne paint to solvent based paint….and back again.
Has anyone experimented with different ways to switch from one to the other and found the “best” way to do it?
Or even any good tips with a method that you’ve always used and never had any reason to try anything different? Found a “best” solvent to use? Quick, efficient, and cost effective…. too much to ask for all three?May 1, 2015 at 1:45 am #6576Girish C. Dubey, President STAR, INC.Participant
First…thanks for the post.
And…it’s not too much to ask for all 3…!
Here’s my rule…only the cutting agents touch each other.
In other words…if I have Latex in my machine…and I want to switch to Acetone…
First…I flush out the Latex, once with water. Then…I flush out the water with Xylene.
Then…then…I flush out the Xylene with the Acetone.
Something else…I always think in terms of; what do I want IN my machine.
I do not think in terms of…how do I get something OUT.
( You get something out by putting something in. )
Again…only the cutting agents touch each other.
Next…then…if I want to switch back to Latex…
First…I flush out the Acetone with Xylene.
Then…I flush out the Xylene with water.
THEN…I flush out the water with Latex.
Does that makes sense?
Next…if…if…I flush out water with Acetone…I get maybe (2) seconds of “silly string” coming from my gun…!
It isn’t a big deal…but…I believe it’s just the Acetone paint “touching” the water and “reacting”.
Yes, I’ve been on a job and had water in the machine. I had NO Xylene…! ( Dummy! ) So…I used the Acetone to flush out the water. Yes…I had silly sting looking stuff coming from the gun…for about (2) seconds…then the Acetone.
No big deal. All is well.
But…my rule…only the cutting agents touch each other.
And…I can flush out with as little as (2) gallons of whatever cutting agent I need.
Bottom line…it’s quick…easy…( flush once )…and I think…best.
I hope I helped.

Makes perfect sense!
How about this scenario….
I have one striper loaded with blue. One with white.
I finish spraying the white and switch that machine to yellow.
Easy, I don’t even have to clean out, just switch my bucket.
But I missed a section of white. So, back to white.
Latex is easy, replace the yellow with water, then the water with white.
(to avoid having light yellow lines) Water is easy and cheap.
But with acetone, I don’t really want to waste the Xylene just to switch colors.
But, when replace the yellow with Xylene, then the Xylene with white….now my xylene is kinda yellow.
Can I keep that xylene to use again?May 1, 2015 at 2:28 am #6578Girish C. Dubey, President STAR, INC.Participant
First…are you ready…?…I never clean my machine.
I know other stripers who never clean their machines.
…who has time…?
Next…mine will also sit with paint in it for days.
Or…the Yellow machine may be in use for days and the White machine sits.
Next…that’s how I keep the buying of Xylene to a minimum.
The “dirty” Xylene will separate in a day. Either use it again or skim it off…etc.

Hmmm, I have always switched from white straight to another color.
BUT, when going from- a) color to color, or b) color to white..
I have always gone – color > water > color(or white) , under the theory that the two colors will contaminate each other.
Thus making wasted paint (or funky colored lines) until color #2 pushes out color#1(….or, white).
Maybe I’ll just have to give ignoring that theory a go!
