Please tell me how I can get it out. I have used ER/80 concentrated and it is not working.

Thanks in advance.

Hi 2MI

Most importantly, did you dilute the ER-80 with water before use?

How did you apply it, and does your hose have a good pressure spray nozzle on it?

2 Mini Irons · October 23rd, 2009

Yes it was diluted. It was sprayed on the screen and let it sit for about 30 seconds. My hose nozzle has been working fine until today.

OK, sounds like you've used the ER80 before and probably mix it at a 1:10 up to 1:30 ratio, chem to water.

FYI- Anything stronger than 1:10 can cause your problem.

Are you spraying er80 solution on both sides of screen, and after application,
do you work it into the emulsion with a brush or sponge to help the dissolving stencil?

When you water-spray remove the stencil, are you starting at the screen bottom and working upwards?

(Sorry for all the questions)

2 Mini Irons · October 23rd, 2009

We sprayed both sides of the screens.
We are using the scrub brush to work it in.
Not sure about the last question but that is probably a no.

If my husband did not do the right ratio then what? When he could not get it off he started using more of the ER-80.

Did the ER80 dry on the screen during the process? If it did, it will essentially "lock" the emulsion on the screen and make it nearly impossible to remove.

2 Mini Irons · October 23rd, 2009

I am not sure. How can you tell if it dried on there. We sprayed them with water after we let it sit for about 30 seconds.

tlbays · October 23rd, 2009

Well, Mini....

If the ER80 is mixed too strong it will actually "over-strip" (over-oxidize) the stencil too fast and lock it in, same as it drying on the surface as Pwear indicated.

If the strong mix is rinsed down before the stencil is fully blown off the mesh, those rinsed areas won't easily reclaim.

That is why stencil removal from the screen bottom upwards can be a good plan in many instances.

Before you fire your husband from his appointed screen duty and create yet another unemployed screen cleaner

,
do you have a self-serve car wash (spray booths) nearby?

2 Mini Irons · October 23rd, 2009

Yes, we do. I should use the sprayers there? How did you know I was going to fire him! Lol

you need a pressure washer.

2 Mini Irons · October 24th, 2009

Yes I did! We got our screens back.

Another solution would have been to use a Haze Remover, let it sit, then wash it out with the pressure washer as mentioned before. I use that stuff on those stubborn screens and I have never looked back.
