Craft Foam Sealing Issues

So, I've googled just about everything to do with craft foam before I even started my newest project of craft foam armor, but I'm still running into some problems. :\

Most tutorials/discussions on sealing craft foam suggest using either Future floor cleaner or Mod Podge.
I'm in Germany at the moment, and I haven't been able to find ANY Future floor cleaner, or even anything similar, so instead I found some Mod Podge at the terribly limited craft shop in my area (it is mostly dedicated to quilting and scrapbooking) and started using that.
Problem is that there are lots of lumpy brush strokes. I read (on a scrapbooking site) that you can sand Mod Podge between coats to decrease the brush strokes. I'm really worried about trying this... >.<; I don't want to sand into the craft foam and mess it up further...

Does anyone have an alternative method, or know more about sanding Mod Podge? Please keep in mind I'm rather limited on what I can get my hands on.

(Edit) Since I've already put something up about this, thought I'd ask a second question. XD I used this ->
http://www.entropyhouse.com/penwiper...helmsdeep.html
<- tutorial and shaped the craft foam, then added glue and fabric to make it all sturdier. When I added the fabric and glue, however, the shape I had formed the armor into was somewhat lost. Is it possible for me re-shape them over heat without a problem? Or will the fabric have made it too sturdy?

Thanks in advance~

The future floor cleaner is actually a transparent floor wax/protectant. You could likely get away with using a similar brand of the same product.

As for reshaping, I think that would be possible as well, but be careful when doing so.

When I couldn't find any Future, I looked for anything in the cleaning/chemical section with the word wax in it's description and didn't find anything. :\
I'll try reshaping the pieces. ^__^ Thanks Nyokun.

i believe some white school glue and some water mixed together (or fabric glue) would work instead of modge podge

You have to wet sand the mod podge with 400+ grit sandpaper.

Future had a name change. It goes by Pledge with Future Shine now. It doesn't say wax on the bottle, but "Floor finish" so I guess you can try getting something that has that on the label.

If it's lumpy, it might also be a brush problem. You can try modge podge with a different paint brush.

I used the same tutorial on my armor and I didn't use future. I used the glue method to seal the foam then put the paint over it and acrylic varnish on the top. I used spray paint for the color since I was going for the hammered metal look. It works just fine. The armor is waterproof and very strong.

Sandpaper works fine, just go easy with it. Like, don't dig it into the stuff. I've used an exacto knife to smooth corners on modpodged craftfoam, so don't worry about messing it up with sandpaper. Add another coat or two after you sand it, using water to thin it out some. Thinner modpodge makes for less visible brushstrokes.

If u want a smooth finish don't touch a brush meaning get a spray version or airbrush but those cost a lot. If u paint the craftfoam with a brush u probably alredy left a brush stroke on it so even if u sand the modpodge u'd still have the brush showing. So avoid a brush if u don't want it showing. As for sealer look in art section for acrlic sealer doesn't have to be modpodge. And add varnish if its getting sticky

No, you won't. Not if you wet sand it. It says so on the back of the bottle and in practice it's entirely effective at removing brush strokes

Hmm interesting. Will that remove the brush strokes from acrylic paint also? Because I try so many method to remove them but so far the best way is just not use brush and spray everything from paint to modpodge spray.

No. It will just work for mod podge. This will probably take off the pant but it will smooth out your sealer. If you want to prevent brush strokes in your paint, brush on several extremely thin coats rather than two or three heavy ones.

My thanks to everyone for the extremely helpful and informative replies.

Since I have more than one piece of armor that has yet to be sealed or painted, I think I'll try out all of the methods mentioned here (except for the Pledge with Future Shine, because I still haven't seen any...) Maybe afterwards I'll make a compendium of the different options and sources for using Craft Foam, just so it's all in one place..... ^___^

you sand it down and then repaint. It can take alot of careful layering and sanding to get a smooth finish.

chiming in my two cents, I've been sealing my craft foam with gesso. I've also used white school glue.
