Wet application on solvent based clear products is the best way to achieve bubble free and optically clear results. Dry applying is possilbe but may result in some bubbles andor reduction in optical clarity. Can I use GF 255 on perforated vinyl since it is optically clear No. While GF 255 is optically clear it is formulated with a removable adhesive and is not designed for conformable applications. GF 255 will not bond well to the perforated film and can create blurry air pockets in the perforations that will block the films one-way vision. If I dont have a soft edged Teflon coated or wet edged squeegee can I use a regular squeege No. We do not recommend this. GF 255 is a clear calendared vinyl and as such it will have a tendency to show squeegee marks. Regular squeegees may have burrs or uneven edges which may make impressions in the vinyl. Sometimes you may be able to heat these impressions out depending on their severity but we do not recommend heating the film on a cold glass surface as cracking may occur. It is best to use a softer edge. You can also use a premask tape to protect the graphic during installation. GF 255 AUGUST 2022 309 S.

O M M E N D E D Allow the printed graphic to dry 24 hrs. or longer depending upon ink coverage. Lamination is optional but can protect if the graphic is going to be cleaned often and also helps during installation handling. 1. Thicker graphics are easier to apply. 2. If using a laminate an optically clear one is recommended. Transfer Tape is a must 1. With tape you can squeegee and reduce the risk of scratching. 2. Helps eliminate bubbleswater entrapment by creating a thicker graphic. 3. Using a paper application tape means you can wet it afterwards and it will remove easier. Clear application tapes will work but you may need to allow drying time before removing it. Removing too early could result in the graphic coming off the glass andor stretching. - Use an approved commercial based application fluid. - Spray the surface of the substrate. - Mist the adhesive side of graphic. - Wet graphic printed surface. - Apply to window and squeegee out all fluids. 1. We recommend a suede tippedTeflon squeegee for wet applications to prevent scratches A P P L I C AT I O N F L U I D S Soap Water Mixture - Although an accepted practice you should take caution when using dishwashing soap. It may be economical but dish soap has detergents and are not designed to be used with vinyl media. There may be soap surfactants that will interfere with adhesion and too many soapy bubbles can be difficult to squeegee out of an applied decal as well.

Marabu Action Tac Works as a cleaner and application fluid. Works on

all vinyl grades. 2. Marabu Window Juice Surface must be clean before use. Can be used to apply the graphic as well as remove the transfer tape spraying it after application to moisten. 3. Marabu Splash Surface must be clean before use. Mix with water. 4. Rapid Tac Cleans the surfaces as well as allowing the film to float until it is properly positioned. 5. Rapid Tac II Works great for glass applications and colder applications 20 F to 140 F. Works with economy calendered intermediate calendered high performance calendered metallic reflective polyester Mylar and other specialty films. 6. Sure Glide Has an adhesive activator which helps set adhesive and speed drying time when applying on metal and other hard surfaces. The key is not to use too much application fluid. The more fluid you use the more fluid you will have to squeegee out which can be labor intensive and hard to do. Fluid removal will ensure maximum bond. PRINTINGLOADING TIPS Loading GF 255 on HP 700700W800800W Latex Printers GF 255 OptiMark Optically Clear Vinyl may require the use of Output Platen Covers. Without these the media may appear to stick to the platen this seems like static but is the vacuum holding it and fold over. You can purchase this accessory at any HP distributor and it can be used on other media as well such as fabrics.
