What can I add to paint to make it dry really, really quickly?

Asked by Dutchess_III (28254 points ) February 25th, 2012

I printed out 3 courses of math, 1st and 2nd semester of each course. We’re talking several 3-ring-binders of paper. Well, then I realized that it printed out the teacher’s version, which includes the answer key. I don’t want to waste a ton of paper and toner re-printing them so I just want to white the answers out. However, I’d end up using 50 zillion white out brush things. Not cost effective plus it would be tedious and sticky. I figured I could get a half pint of white paint and a thin artists brush and do the same thing much more quickly and cheaply. However, I need the paint to dry as quickly as possible.
Would adding alcohol do the trick do you think? Any other thoughts?

I’m not sure what you could add, but a fan would help them dry quicker. Obviously, you’d have to clip the pages to something, or weigh them down to keep them from blowing away. What about using a black sharpie to cover them up?

Sharpie, yah…but…it would look sloppy. I just have this thing about nice n neat, especially in my classroom. I feel like people learn better when things are nice to look at and well organized. I don’t know if it’s true or not.
Fan would be waaaaay too much trouble. We’re talking hundreds of pages that also have to stay in order.

I’d use permanant roll-on glue tape. You can buy it at Staples and it works like the white-out tape, but can’t be removed.

Just get a little bottle of acrylic paint in the craft section of Walmart or wherever. It dries very quickly as long as you aren’t putting a ton of it on anything. Like within 10 minutes it will be fairly dry.

I used to do a lot of layering on my paintings and I always used acrylics because I couldn’t finish paintings if I had to wait forever for a layer to dry.

I’ve always found it easier to say screw it, cut your losses and redo the printing. Reuse the waste paper for scrap paper.

Use some watered down exterior primer like for houses. Mix in [⅔water ⅓ paint thinner] equal part to [the paint] and get the thickness how you want it. Should dry pretty fast but needs to be done outdoors. You could also try stickers or something to cover up the answers

I would be any enterprising person would find a way to scrape off the paint. I also wonder about anything stick on because steam, hair dryers or freezing will remove almost any sort of stick on. I think I would take a black magic marker and black out the secret stuff, I think that would be the most foolproof method.

(When I was at Georgetown U years ago, an information booklet went out and it listed Father So and So a 92 year old Jesuit as the Director of Pubic Relations. Someone forgot the “L.” They quickly became collector’s items. I probably still have mine somewhere. I hadn’t thought of that in years but your question brought it to the front of my mind.)

@rooeytoo I don’t think paint would “scrape off” of paper very well. It would be more likely to just tear a hole in the paper.
I think I’ll go with the permanent marker, in different colors. Unless other colors won’t cover up the stuff, but we’ll see.
