    I put two coats of polycrylic on a small acrylic on hardboard painting and got this

    the first layer was completely dry before I applied the second coat. I didn't notice any crackling on the first layer.

    I like a glossy finish, not too keen on satin. This was semi-gloss – which suits my taste – the crackling not so much. I didn't apply an isolation layer, but doesn't seem like this would cause that effect with the polycrylic.

    Has it crackled only over that pink area – or can we just not see it over the blue?
    Just wondering if the paints differ at all?

    It has an even layer or crackle over the entire painting(12″x12″)-except for the green triangle of water and the cat at the bottom.

    This will not be helpful to you at all but I love the crackle effect! I do know that there are mediums sold solely to have this effect.
    The other thing I keep learning the hard way, the back of a canvas can have as much of an effect of the painting as the front.

    I do like your sky and mountain however!

    the painting is of a maneki neko and Mt. Fuji in the aftermath of the earthquake and tsunami that hit Fukushima, Japan in 2011.

    The crackle kinda-sorta works for this painting – but I can't use polycrylic again until I can predict the outcome.

    I've just read that you should wait at least a week before applying polycrylic.
    Is that helpful?

    Another thought – did you spray thinly? Too thick might pose a problem of layers drying evenly?

    How long did it take for the crackling to happen? I have a few pictures of paintings I've done and coated with Polycrylic (Minwax, correct?)

    I've used it on two projects, and I really thought I was protecting my work.
    Project #1, from last June 2018ish. Wood. I primed, then put on a coat of black Gesso before painting with acrylics.

    Painting #3: Feb 2019, Acrylic on ACM panel (gesso primer)

    As an aside, if in fact I should NOT be using this to protect acrylic paintings, what should I use to preserve my paintings?

    The painting was at least a month old before I applied the polycrylic. The first layer didn't appear to have any crackling – but I didn't inspect it that closely and it was in a dimly lit room – so I can't say for sure. The polycrylic is a liquid brush on – not a spray.

    This morning I applied a third coat -the 2nd coat I had applied very thin, maybe too thin?? The third coat I applied liberally. I wish I had sanded it first, but I didn't think to try that until I had already applied the third coat. It's dry now and it appears that the third coat did not crackle and made the crackle from the second coat less noticeable

    I would use something else on acrylic paintings. I use polycrylic over paper, and think it's a great material. I have also put polycrylic over "troubled" areas of acrylic paint (that perhaps spread or split due to mixing things that shouldn't be mixed). You could call polycrylic and ask. You're probably better off using one of Golden's products as final protection layer to your paintings. Their site is full of information and you can also call them for advice.

    If Polycrylic is applied heavily it may feel dry to the touch but underneath may not be fully cured. A second application applied heavily will cause that type of alligatoring. I use Poly all the time on different surfaces and have not experienced this except when I was in a hurry and did the above.

    I think you're onto something. I read that if you put a thin coat over a thick coat, the thin coat can dry before the thick coat underneath. A breeze for example to speed up the drying of the topcoat.

    This apparently is a common problem with poured acrylics – called craving(?).
