BANNER INSTALLATION GUIDELINES

Below are some guidelines to follow when finishing and installing banners. These tips and tricks will apply to wet-strength paper, fabric, vinyl, polyethylene and polypropylene films, and non-woven banner materials.


OVERPROTECT:


Use Magic DMFTP or a thin pressure sensitive adhesive. One sided applications can result in curl towards the laminated side and possibly contribute to adhesion failure. Compatible sprays or roll-ons can be used but may not provide uniform coverage. Pretest overprotection layer prior to use.



HEM EDGES:


For durability, hem edges by either sewing or using banner tape. The right and left sides are hemmed first, then the top and bottom lengths. If using rope, it should be added into the top and bottom hemline at this time, before the hem is secured.

*Sewing: If unlaminated, stitch hem side up to avoid scratching image with the sewing machine foot. For maximum reinforcement, use a double-stitched hem with a double lock stitch, with a maximum of 5 stitches per inch.

*Banner Tape: Apply standard high tack banner tape to the back of the banner. Fold edge over and press securely. Pretest banner tape prior to actual job.



INSTALL GROMMETS AND REINFORCE CORNERS:


*Grommets: Place grommets every 2 feet apart in the hem line along the length of the banner so that the grommet penetrates 2 layers.

*Reinforce corners: To increase durability and strength, reinforcements can be made with small 2″ to 3″ patches of nylon or an additional cut piece of banner or adhesive grommet tab products, such as BANNER-UPS®. Grommets should go through all corner layers.



CUT WIND SLITS:


Some installers prefer wind slits on scrim banners over 10 feet. Cut 6″ wind slits in the shape of a half moon - in the direction of the letter ″U″, approximately 2 feet apart across the center of the banner.



HANG:


Corners can be secured using the installed rope or bungee cords. Apply equal tension on all 4 corners assuring the banner is taut but not tight. Too much tension can result in premature failure. The banner should not flap in the wind.
