    BUTT SEAMS
    [​IMG]

    I've heard that this is a great way to install a wall mural, especially with materials like phototex. I've read (on this site) and had sales people say to me: it's easy... just overlap, cut through both layers and remove the two waste pieces and you have a virtually unnoticeable seam.

    My questions is how are people doing this on a normal drywalled and painted wall? To cut through two layers of phototex you have to use a fair amount of force. If you don't fully cut through these fabric-style materials, you get loose threads which is no good. If you cut hard enough, you cut into the paint and drywall, which then makes it have a raised ridge. Maybe with dark coloured graphics this might not be noticeable but with lighter graphics you see this black line. Not to mention when they remove the graphics they'll have all these slices in their wall that they need to fix.

    I was thinking of laying a protective strip under the edge, then cutting on that and removing it after - quite a bit of extra work. Ever since I tried it once I have just left overlapping edges. But someone is saying they don't like overlaps, so I'm considering trying this again.

    Curious to know.. has anyone done this type of butt seam with phototex or similar and had good results?

    Yellowtools might have a solution to help you cut those butt seems. They are also an MM on here.

    I just leave the layered seam. I have never had a complaint from it. You don't notice it really, and with some vinyls, you can barely even feel it.
    I tried doing what you described years ago, and like you said, I ended up with parts that frayed, and cut too deep into the wall, so when peeling up the excess strip, it also took a piece of painted drywall with it.

    The yellotools one works pretty well. The one with the teflon shoe is pretty expensive, but does work well. If you are going to go that route, you will need a larger overlap. I'd say nothing less than about 2". Look into doing but seams with dinoc. Can work in a very similar fashion. The wrap institute has some videos on doing it. When I went for my dinoc certification, they taught us to do them in the same fashion as what Justin shows on the wrap institute.

    So you mean using the bodyguard knife? Never thought of that... I see why you'd need a nice big overlap in that case you have to lift vinyl a bit, and starting the cut seems like it might be fun. Not to mention it won't be a perfectly straight cut as when using a ruler or guide. Interesting
