Here's a quick, easy and inexpensive way of mounting a poster in a permanent and clean-looking way. I bought this poster as a contrast to my 3D periodic table, and wanted to do Murray Robertson's great artwork justice as opposed to just pinning it to the wall. There are other descriptions of how to make plywood-backed posters, but the poster I got was thick and glossy and I was concerned that the mod podge approach might not be best suited to the my poster. So I used spray-on contact adhesive instead, and it worked well enough that I thought I'd share the process.

Step 1: Materials and Preparation

- poster. Make sure the poster is nice and flat. I left mine between two sheets of plywood overnight.
- spray adhesive. I used Super 77, but I assume any contact cement spray adhesive would work.
- plywood. Thicker and higher quality the better, for planarity and edge appearance, respectively. Cut to the size of the poster or slightly larger.
- a large sheet of paper. I stuck two pieces of brown butcher paper together with masking tape. The paper needs to be bigger than the poster.
- finish for the edges. I used Varathane water-soluble crystal clear finish.

<p>This looks fantastic! I love the look of the plywood edges. I thought I would prefer a flat black edge, but the plywood looks very clean and modern. Did you only clear finish the edges? I was thinking clear finishing the entire front for both protection (scratches/fading) and keeping the edges of the poster down. Also, what thickness of plywood are you using here?</p>
<p>Yes, I only did the edges. Probably should have done the back too but I was in a massive hurry. No signs of peeling of the poster - that glue is pretty effective. 3/4&quot; plywood. </p><p>Note the main error I made was using a piece of plywood that had been stored outside in humid conditions. When it dried (weeks), it warped. I strongly suggest storing the plywood flat inside before posterizing it.</p>
<p>Why not a piece of foam core mounting board? It should be lighter, cheaper and easier to work with than plywood.</p><p>Also, I think the acid from the plywood will have a negative effect on the poster over time.</p>
<p>Flatter, thicker and more rigid, and I like the look of the plywood edge in this context. This poster is pretty thick - almost like glossy card than paper. I suspect it will fade faster from light on the face than acid leaching from the back. The contact adhesive will make for a pretty good barrier.</p>
<p>Contact adhesive will melt foam core ;) ask me how I know...</p>
<p>How do you know? :P</p><p>Seriously, I'd like to hear your story. What materials/brands were your poster, your foam core, and your adhesive, exactly? I'm sure most adhesives would melt foam, but I didn't know spray adhesive would penetrate the card stock or poster board that covers foam core.</p>
I apologize, I wasn't using foam core but The phone sheeting insulation for house.
<p>I see some blue tape on the edges of the poster in that next-to-last photo. Was that to protect them from the clear finish? Is that painter's tape? I'm not familiar with it; is it easy to remove without damaging paper? Was your poster glossy?</p>
<p>Very nice. I've seen and used the dowel technique, but I like this approach much better. Good stuff! :)</p>
<p>Thanks. Not sure what the dowel technique is, but I imagine they take the place of the paper? Was really hustling this weekend so didn't get time to research this as thoroughly as I probably should have</p>
Ha, sorry! Yes, you lay out a bunch of dowels to hold the top layer away from the bottom, and remove them one at a time. I think it might be a trick I saw from someone making laminate countertops.
<p>The dowel technique works well with a rigid product like laminate counter or wood veneers, but something flimsy like a poster seems to need the paper mask to prevent accidental contact. Also with dowels you usually start in the center and work outward. The goal is to prevent bubbles. Starting at one end and towards the other should also work. I would use a window tint squeegee.</p>
<p>Looks great! How did you hang it?</p>
<p>Thanks. I've not yet - it is standing on an easel. I'll probably just put a couple of screws in and put some wire between them</p>
This is the first successful way I've seen for doing this! Wish I had this info 40 years ago!
<p>Nice! The Varaithane is awesome stuff and will make the edges waterproof (for humid environments) and chip proof. </p>
<p>Easier than I tought, Thanks!</p>
<p>I like that you used the Periodic table of elements as the poster.</p>
