P95 Acrylic

[2B]

We had a customer come in asking to get signs done with P95 Acrylic, the catch is they want it different colors (1 color per sign) but only on the back of the sign and not doing colored Acrylic. the sign will be attacthed to the wallso it needs to be able to hold its weights and adhere good to the VHB adhesive
tape.

We have looked into oil & acrylic paints, but the time it takes to cure the paint is an issue for scheduling.

are there other methods / options for "coloring" the back of the acrylic?

Check with a sign or print shop. Where in Texas are you located. I know one or two I could recommend.

Central Texas, The customer is VERY ADAMANT that the work is done in house, that is the reason for the post. We can do it, and have done it with oil based paints as the current method but taking to long to cure. we have also looked at AcryliPrint® HD FusionProcessor but the cost for the machine is a hefty. Our post is looking for input on different processes that have been done/tested and what the outcome was.

we paint the back of P95 acrylic all the time with standard latex house paint, you just have to be careful not to scratch it off, but if you do just touch it up, the P95 is so frosted you can't tell where it was touched up anyways.

I have also see it screen printed from the back

rush the painter but not the paint

How large or small are these panels, if they are fairly small use the spray plastic paint from Krylon or Rustoleum(sp) and when that dries back with calendered vinyl of the same color family to make the color solid looking from the front. You can also do this with oil based paint using a roller but that does take at least 24 hours to set up before putting on vinyl.

Maybe I am a little naive but can't you just throw down a solid layer of vinyl with the big squeegee or laminator?

the size is 8"x8", we have been using the paint approach, unfortunately the paint is slowing down the production. Not in the drying aspect but the curing aspect because as the paint cures it releases fumes, and the released fumes are causing the VHB tape to release from the paint. so we are having to wait the full cure cycle. This leaves little time for the assembly.

Vinyl was our first though, unfortunately not all of the colors can be located in vinyl. Have looked @ 3M, Avery, Oracal, etc...

We paint with Krylon, regular or Fusion, one day and cover with vinyl to prevent scratching the next day, have never had a problem with tape coming off.

When you paint are you using roller or spray?
Do you use a like color vinyl to help uniformity?

When we do a single layer of acrylic there are no issues. it is when the multiple layers are done, that is when the "curing fumes" are becoming an issue, since they have no where to vent.
the VHB tape was being applied to the paint with no vinyl overlay.

We typically use Krylon or Fusion spray with one good coat. The backing vinyl would normal be calendered of a similar color, however if the paint is light such as ivory or light yellow we would use white. Typically ADA signs are mounted on a wall so they don't get any back light so the color of the vinyl doesn't make much difference. If you use Fusion and should find you need a 2nd coat, you need to spray with in an hour or 2of the first coat or it will cause the first coat to wrinkle.

Side note, on the layout that was attached, the braille on the sign with 101A, the A is missing in the braille.

We were doing it with a roller and that is where IMO the problem is coming from with too much paint being applied.

the solid walls are no worries, the reason for asking about the similar vinyl was regarding glass walls.

oops my bad, guess I should had proofed the layout before posting, wasn't even thinking about the braille. That's what happens when you check yourself. was really just using to show the different layers.

Just an FYI, but your restroom signs are not techinically compliant to the ADA regs -

703.6.1 Pictogram Field. Pictograms shall have a field height of 6 inches minimum. Characters and braille shall not be located in the pictogram field.

703.6.3 Text Descriptors. Pictograms shall have text descriptors located directly below the pictogram field. Text descriptors shall comply with 703.2, 703.3 and 703.4.

Also, the Braille shown on your drawing is not Grade 2.

FWIW,

The file name is incorrect for that I am sorry for misleading anyone, its outside the edit post time frame or it would already be changed.

Thanks, goes back the braille not being proofed first. When you don't ensure quality it shows in more ways than one.

these are NOT the templates that are used for ADA compliant production. merely a visual aide in showing the difference between the single layer and multi-layered.

Man I'm glad I don't have to do any braille.
