  • problem with wall graphics

    Posted by Shane McNamee on 21 January 2009 at 10:43

    Hello all.
    We’ve been doing large format, digitally printed wall graphics for the past couple of years (must be 1000’s of sq meters at this stage!), but are having major problems on 3-4 large jobs (so far!?) that were installed over the past 5-6 weeks or so.
    The graphics seem to apply fine, but in a matter of a day or two, are starting to come away from the wall surface. We’ve been using an Emblem monomeric permanent Vinyl for all that time, and never had this problem before. They are all internal graphics (shopping centers, airport lounges, shops etc), applied to emulsion painted walls, but the vinyl just doesn’t seem to want to bond to the wall. We suspect a change in the material, but could it be anything else?

    We fit all kinds of prints and cut vinyls to exhibition stands, and have the same problems every now and again. I can only put it down to the type of paint and certain colours used, but cant be more specific than that. Also the atmospheric conditions play apart, ie extreme humidity and heat changes from day tonight.

    Very frustrating as we always use the same materials.

    Pretty much what Ian has said above.. pigment in the paint can cause problems especially with dark paint…

    I agree that its probably the paint. Flat, matt or satin is always an issue, but especially if it hasn’t cured or dried properly.

    Some painters push the envelope and recoat before the base coat is dry. They tend to ‘outgas’ a bit longer in that case.

    Best way to know is if the paint still ‘smells’. If you can smell it, its not dry.

    Also, here in Oz we have these paints with teflon or ‘cleaning’ qualitys.

    Basically, if the paint is designed not to stain, it will not let adhesive grip properly either.

    If the weather is cold, and its been painted, I’d hazard a guess the paint is still curing…..

    You’d correctly expect the permanent glue would be pretty aggresive. More reason to suspect the paint in my book.

    Cheers

    different manufacturers of plasterboard
    whether the plasterboard has been sealed
    the number of coats and the paint used

    all have an effect on how and adhesive performs….so I was told 😀

    I would imagine the material is fine 😀

    Hi,

    What’s the best type of paint to use when sealing the wall if vinyl is to be used?

    another daft question… when quoting what’s the average price per sq ft / metre for full wall graphic? I don’t do wall wraps at the moment just looking into it.

    Cheers

    Stu, the very best paint would be an enamel, but a gloss acrylic is almost as good, and it dries quicker. Depends on the budget of course.

    Your wall graphic pricing depends on your own expenses. Work out what it costs to produce, taking in to account the material cost, your labour in time, and the margin you need to make it worthwhile.

    Everyones price will differ depending on their company structure, and the margins they want/need to make it worthwhile.
