    I have to apply translucent vinyl to two sheets of substrate a customer got at Laird Plastics.
    I dunno what it is exactly. It's white plastic but whether it is polycarb, Lexan, acrylic or whatever is not obvious.
    It's masked with a tan masking that reads TG MASKING by PLASTIKOTE.
    My question is:
    Does it have a "good" side or are both sides OK?
    Also, do I let it outgas after unmasking?
    :thankyou:
    Love....Jill

    Tap on it with your finger. If it sounds "metallic", it's polycarbonate (Lexan). If it sounds "dull", it's acrylic.

    Both sides are fine to use. It doesn't have to outgas.

    Hmmm. It sounds neither! Just glad that either side is OK to use. Thanks.
    The masking is the same on both sides.
    I loathe this type of sign.
    Customer bought a used sign from CL and wanted me to strip the faces...I sent him to Laird Plastics.

    Sounds like acrylic with the tan mask .. I would be safe and let it "outgas".. I personally have never had issues with applying right away, but might as well be safe.. Polycarb usually has a clear mask on it .. would come to you rolled up if the length is long enough .. both sides are ok if it is acrylic..

    Thanks again. I do remember the last time I got polycarb that it was rolled up.
    And the acrylic I bought had a brown masking that was delightful to remove.
    I'll unmask these today and cut the vinyl tomorrow.

    Luckily this seems pretty fresh.
    I go from the "high" of just having a customer tickled pink to pick up a hand painted sign to now dealing with plastic fantastic.

    Removing the brown mask is a joy, especially when it gets old.
    I find a cardboard tube about the same width as the acrylic, peel up a few inches of mask from the edge of the plastic, wrap it around the tube, and roll the mask off in one piece.

    If the paper mask does prove difficult a light soak with paint thinner will make it easy

    Given the masking has TG on it, i am going to weigh in on PETG, which laird does carry. Have you considered calling laird and finding out what your customer purchased?

    I unmasked 'em. Easy as pie, masking was some weird tan plastic stuff.
    Will cut-n-stick tomorrow.
    I could call, but I have to go to my "real" job now.
    Thanks again!
