sorry for the basic question but im using so many brushes its driving me nuts!
i can clean th ebrush with acetone no problem but im worried that if i then reuse that brush then any remaining acetone on the brush may cause a problem when applying more resin???
Just let it full dry before reusing them. I have a spot on top of a media blast cabinet I have the students to place the cleaned (weather Resin Emulisfier or acetoned cleaned) tools to dry and at the next class I put them back into a bucket in the spray booth for reuse.
I also tell them to dip any brush into acetone before using them as if there’s a slight trace of resin emulisfier and you do a lay up, it will blister after getting the part out into the sun at a later date…:oops:
You can use acetone as a thinner for PER but I’m not sure on epoxy.
thanks for that,im just using poly at the mo,i think when it comes to epoxy parts i will be happy enough wasting a brush per part,but im only doing molds at the mo.
you’ll actually spend more money/time than it’s worth. Just throw them away. I can get 2" chip brushes in bulk for $0.35 each.
ive bought about 100 brushes so far and if im making a mold and do it in say 4 stages,thats 4 brushes,at the moment im washing some and saving them for less criticle uses like the final layers on a mold etc.cheapest you can get in the uk is about 40p eack which is about 80 cents.
If you are using epoxy, the best cleaning solution is laquer thinner. I have used acetone and the emulsifier for poly and vinyl. I agree that you are paying more, and it is probably cheaper as long as it is a hobby, but once you get into a shop, it is not wise to spend the labor dollars on cleaning.
I see Jm’s point of cleaning since the students aren’t paid and funds are hard to come by.
